A diction for addiction: A brief overview of our papers at the 2017 International Conference on Behavioral Addictions

This week I attended (and gave one of the keynote papers at) the fourth International Conference on Behavioral Addictions in Haifa (Israel). It was a great conference and I was accompanied by five of my colleagues from Nottingham Trent University all of who were also giving papers. All of the conference abstracts have just been published in the latest issue of the Journal of Behavioral Addictions (reprinted below in today’s blog) and if you would like copies of the presentations then do get in touch with me.

Griffiths, M.D. (2017). Behavioural tracking in gambling: Implications for responsible gambling, player protection, and harm minimization. Journal of Behavioral Addictions, 6 (Supplement 1), 2.

  • Social responsibility, responsible gambling, player protection, and harm minimization in gambling have become major issues for both researchers in the gambling studies field and the gaming industry. This has been coupled with the rise of behavioural tracking technologies that allow companies to track every behavioural decision and action made by gamblers on online gambling sites, slot machines, and/or any type of gambling that utilizes player cards. This paper has a number of distinct but related aims including: (i) a brief overview of behavioural tracking technologies accompanied by a critique of both advantages and disadvantages of such technologies for both the gaming industry and researchers; (ii) results from a series of studies carried out using behavioural tracking (particularly in relation to data concerning the use of social responsibility initiatives such as limit setting, pop-up messaging, and behavioural feedback); and (c) a brief overview of the behavioural tracking tool mentor that provides detailed help and feedback to players based on their actual gambling behaviour.

Calado, F., Alexandre, J. & Griffiths, M.D. (2017). Youth problem gambling: A cross-cultural study between Portuguese and English youth. Journal of Behavioral Addictions, 6 (Supplement 1), 7.

  • Background and aims: In spite of age prohibitions, most re- search suggests that a large proportion of adolescents engage in gambling, with a rate of problem gambling significantly higher than adults. There is some evidence suggesting that there are some cultural variables that might explain the development of gambling behaviours among this age group. However, cross­cultural studies on this field are generally lacking. This study aimed to test a model in which individual and family variables are integrated into a single perspective as predictors of youth gambling behaviour, in two different contexts (i.e., Portugal and England). Methods: A total of 1,137 adolescents and young adults (552 Portuguese and 585 English) were surveyed on the measures of problem gambling, gambling frequency, sensation seeking, parental attachment, and cognitive distortions. Results: The results of this study revealed that in both Portuguese and English youth, the most played gambling activities were scratch cards, sports betting, and lotteries. With regard to problem gambling prevalence, English youth showed a higher prevalence of problem gambling. The findings of this study also revealed that sensation seeking was a common predictor in both samples. However, there were some differences on the other predictors be- tween the two samples. Conclusions: The findings of this study suggest that youth problem gambling and its risk factors appear to be influenced by the cultural context and highlights the need to conduct more cross-cultural studies on this field.

M.D, Magi, A., Király, O., Barta, C. & Urbán, R. (2017). Reward Deficiency Syndrome Questionnaire (RDSQ):
A new tool to assess the psychological features of reward deficiency. Journal of Behavioral Addictions, 6 (Supplement 1), 11.

  • ‘Reward Deficiency Syndrome’ (RDS) is a theory assuming that specific individuals do not reach a satisfactory state of reward due to the functioning of their hypodopaminergic reward system. For this reason, these people search for further rewarding stimuli in order to stimulate their central reward system (i.e., extreme sports, hypersexuality, substance use and/or other addictive behaviors such as gambling, gaming, etc.). Beside the growing genetic and neurobiological evidence regarding the existence of RDS little re- search has been done over the past two decades on the psychological processes behind this phenomenon. The aim of the present paper is to provide a psychological description of RDS as well as to present the development of the Reward Deficiency Syndrome Questionnaire (developed using a sample of 1,726 participants), a new four-factor instrument assessing the different aspects of reward deficiency. The results indicate that four specific factors contribute to RDS comprise “lack of satisfaction”, “risk seeking behaviors”, “need for being in action”, and “search for overstimulation”. The paper also provides psychological evidence of the association between reward deficiency and addictive disorders. The findings demonstrate that the concept of RDS provides a meaningful and theoretical useful context to the understanding of behavioral addictions.

  • Background and aims: The Ten-Item Internet Gaming Disorder Test (IGDT-10) is a brief instrument developed to assess Internet Gaming Disorder as proposed in the DSM­5. The first psychometric analyses carried out among a large sample of Hungarian online gamers demonstrated that the IGDT-10 is a valid and reliable instrument. The present study aimed to test the psychometric properties in a large cross-cultural sample. Methods: Data were collected among Hungarian (n = 5222), Iranian (n = 791), Norwegian (n = 195), Czech (n = 503), Peruvian (n = 804), French­speaking (n = 425) and English­ speaking (n = 769) online gamers through gaming­related websites and gaming-related social networking site groups. Results: Confirmatory factor analysis was applied to test the dimensionality of the IGDT-10. Results showed that the theoretically chosen one-factor structure yielded appropriate to the data in all language­based subsamples. In addition, results indicated measurement invariance across all language-based subgroups and across gen- der in the total sample. Reliability indicators (i.e., Cronbach’s alpha, Guttman’s Lambda-2, and composite reliability) were acceptable in all subgroups. The IGDT- 10 had a strong positive association with the Problematic Online Gaming Questionnaire and was positively and moderately related to psychopathological symptoms, impulsivity and weekly game time supporting the construct validity of the instrument. Conclusions: Due to its satisfactory psychometric characteristics, the IGDT-10 appears to be an adequate tool for the assessment of internet gam- ing disorder as proposed in the DSM-5.

Throuvala, M.A., Kuss, D.J., Rennoldson, M. & Griffiths, M.D. (2017). Delivering school-based prevention regarding digital use for adolescents: A systematic review in the UK. Journal of Behavioral Addictions, 6 (Supplement 1), 54.

  • Background: To date, the evidence base for school-delivered prevention programs for positive digital citizenship for adolescents is limited to internet safety programs. Despite the inclusion of Internet Gaming Disorder (IGD) as a pro- visional disorder in the DSM-5, with arguable worrying prevalence rates for problematic gaming across countries, and a growing societal concern over adolescents’ digital use, no scientifically designed digital citizenship programs have been delivered yet, addressing positive internet use among adolescents. Methods: A systematic database search of quantitative and qualitative research evidence followed by a search for governmental initiatives and policies, as well as, non­profit organizations’ websites and reports was conducted to evaluate if any systematic needs assessment and/or evidence-based, school delivered prevention or intervention programs have been conducted in the UK, targeting positive internet use in adolescent populations. Results: Limited evidence was found for school-based digital citizenship awareness programs and those that were identified mainly focused on the areas of internet safety and cyber bullying. To the authors’ knowledge, no systematic needs assessment has been conducted to assess the needs of relevant stakeholders (e.g., students, parents, schools), and no prevention program has taken place within UK school context to address mindful and positive digital consumption, with the exception of few nascent efforts by non­profit organizations that require systematic evaluation. Conclusions: There is a lack of systematic research in the design and delivery of school-delivered, evidence-based prevention and intervention programs in the UK that endorse more mindful, reflective attitudes that will aid adolescents in adopting healthier internet use habits across their lifetime. Research suggests that adolescence is the highest risk group for the development of internet addictions, with the highest internet usage rates of all age groups. Additionally, the inclusion of IGD in the DSM-5 as provisional disorder, the debatable alarming prevalence rates for problematic gaming and the growing societal focus on adolescents’ internet misuse, renders the review of relevant grey and published research timely, contributing to the development of digital citizenship programs that might effectively promote healthy internet use amongst adolescents.

  • Despite being one of the most popular activities among adolescents nowadays, robust measures of Social Media use and representative prevalence estimates are lacking in the field. N = 5961 adolescents (49.2% male; mean age 16.6 years) completed our survey. Results showed that the one-factor Bergen Social Media Addiction Scale (BSMAS) has appropriate psychometric properties. Based on latent pro le analysis, 4.5% of the adolescents belonged to the at-risk group, who reported low self-esteem, high level of depression and the elevated social media use (34+ hours a week). Conclusively, BSMAS is an adequate measure to identify those adolescents who are at risk of problematic Social Media use and should therefore be targeted by school-based prevention and intervention programs.

  • Background and aims: To our best knowledge, no scale ex- ists with strong psychometric properties assessing problematic pornography consumption which is based on an over- arching theoretical background. The goal of the present study was to develop a short scale (Problematic Pornography Consumption Scale; PPCS) on the basis of Griffiths` (2005) six-component addiction model that can assess problematic pornography consumption. Methods: The sample comprised 772 respondents (390 females; Mage = 22.56, SD = 4.98 years). Items creation was based on the definitions of the components of Griffiths’ model. Results: A confirmatory factor analysis was carried out leading to an 18­item second­order factor structure. The reliability of the PPCS was good and measurement invariance was established. Considering the sensitivity and specificity values, we identified an optimal cut­off to distinguish between problematic and non-problematic pornography users. In the present sample, 3.6% of the pornography consumers be- longed to the at-risk group. Discussion and Conclusion: The PPCS is a multidimensional scale of problematic pornography consumption with strong theoretical background that also has strong psychometric properties.

More mass debating: Compulsive sexual behaviour and the internet

The issue of sex addiction as a behavioural addiction has been hotly debated over the last decade. A recent contribution to this debate is a review by Shane Kraus and his colleagues in the latest issue of the journal Addiction that examined the empirical evidence base for classifying compulsive sexual behaviour (CSB) as a behavioural (i.e., non-substance) addiction. The review raised many important issues and highlighted many of the problems in the area including the problems in defining CSB, and the lack of robust data from many different perspectives (epidemiological, longitudinal, neuropsychological, neurobiological, genetic, etc.).

As my regular blog readers will know, I have carried out empirical research into a wide variety of different behavioural addictions (gambling, video gaming, internet use, exercise, sex, work, etc.) and have argued that some types of problematic sexual behaviour can be classed as sex addiction depending upon the definition of addiction used. I was invited by the editors of Addiction to write a commentary on the review and this has just been published in the same issue as the paper by Kraus and colleagues. This blog briefly looks at the issues in that review that I highlighted in my commentary.

For instance, there are a number of areas in Kraus et al.’s paper that were briefly mentioned without any critical evaluation. For instance, in the short section on co-occurring psychopathology and CSB, reference was made to studies claiming that 4%-20% of those with CSB also display disordered gambling behaviour. I pointed out that a very comprehensive review that I published with Dr. Steve Sussman and Nadra Lisha (in the journal Evaluation and the Health Professions) examining 11 different potentially addictive behaviours also highlighted studies claiming that sex addiction could co-occur with exercise addiction (8%-12%), work addiction (28%-34%), and shopping addiction (5%-31%). While it is entirely possible for an individual to be addicted to (say) cocaine and sex concurrently (because both behaviours can be carried out simultaneously), there is little face validity that an individual could have two or more co-occurring behavioural addictions because genuine behavioural addictions consume large amounts of time every single day. My own view is that it is almost impossible for someone to be genuinely addicted to (for example) both work and sex (unless the person’s work was as an actor/actress in the pornographic film industry).

The paper by Kraus et al also made a number of references to “excessive/problematic sexual behavior” and appeared to make the assumption that ‘excessive’ behaviour is bad (i.e., problematic).  While I agree that CSB is typically excessive, excessive sex in itself is not necessarily problematic. Preoccupation with any behaviour in relation to addiction obviously needs to take into account the context of the behaviour, as the context is far more important in defining addictive behaviour than the amount of the activity undertaken. As I have constantly argued, the fundamental difference between a healthy excessive enthusiasms and addictions is that healthy excessive enthusiasms add to life whereas addictions take away from them.

The paper also appeared to have an underlying assumption that empirical research from a neurobiological and genetic perspective should be treated more seriously than that from a psychological perspective. Whether problematic sexual behaviour is described as CSB, sex addiction and/or hypersexual disorder, there are thousands of psychological therapists around the world that treat such disorders. Consequently, clinical evidence from those that help and treat such individuals should be given greater credence by the psychiatric community.

Arguably the most important development in the field of CSB and sex addiction is how the internet is changing and facilitating CSB. This was not even mentioned until the concluding paragraph yet research into online sex addiction (while comprising a small empirical base) has existed since the late 1990s including sample sizes of up to almost 10,000 individuals. In fact, there have been a number of recent reviews of the empirical data concerning online sex addiction including its treatment including ones by myself in journals such as Addiction Research and Theory (in 2012) and Current Addiction Reports (in 2015). My review papers specifically outlined the many specific features of the Internet that may facilitate and stimulate addictive tendencies in relation to sexual behaviour (accessibility, affordability, anonymity, convenience, escape, disinhibition, etc.). The internet may also be facilitating behaviours that an individual would never imagine doing offline such as cybersexual stalking.

Finally, there is also the issue of why Internet Gaming Disorder was included in the DSM-5 (in Section 3 – ‘Emerging measures and models’) but sex addiction/hypersexual disorder was not, even though the empirical base for sex addiction is arguably on a par with IGD. One of the reasons might be that the term ‘sex addiction’ is often used (and arguably misused) by high profile celebrities as an excuse to justify their infidelity (e.g., Tiger Woods, Michael Douglas, David Duchovny, Russell Brand), and is little more than a ‘functional attribution’. For instance, the golfer Tiger Woods claimed an addiction to sex after his wife found out that he had many sexual relationships during their marriage. If his wife had never found out, I doubt whether Woods would have claimed he was addicted to sex. I would argue that many celebrities are in a position where they are bombarded with sexual advances from other individuals and have succumbed. But how many people would not do the same thing if they had the opportunity? Sex only becomes a problem (and is pathologised) when the person is found to have been unfaithful. Such examples arguably give sex addiction a ‘bad name’, and provides a good reason for those not wanting to include such behaviour in diagnostic psychiatry texts.

Net bets: What makes betting online attractive to gamblers?

Over the past two decades I have carried out a lot of research on what factors are important in attracting people to engaging in online activities such as online video gaming, online gambling, online shopping, and online sex. Research has shown that virtual environments have the potential to provide short-term comfort, excitement and/or distraction – all of which can be highly reinforcing to internet users. My research has consistently shown that there are many generic factors that facilitate online use including accessibility, anonymity, affordability, convenience, escape, immersion, interactivity, disinhibition, and simulation. Today’s blog briefly examines these factors.

unknownonline-gambling

Accessibility Access to the Internet is now commonplace and widespread, and can be done easily from the home, the workplace and (via mobile gambling) on the move. Given that the uptake of consumptive behaviours is strongly correlated with increased access to the activity, it is not surprising that the incidence of activities like online gambling and online gaming is slowly increasing across different populations across the world. Fundamentally, increased accessibility of these activities enables the individual to rationalize involvement by removing previously restrictive barriers such as time constraints emanating from occupational and social commitments.

Anonymity – The anonymity of the Internet allows users to privately engage in such activities as sex and gambling without the fear of stigma. This anonymity can also provide the user with a greater sense of perceived control over the content, tone, and nature of the online experience. Anonymity also has the capacity to increase feelings of comfort since there is a decreased ability to look for, and thus detect, signs of insincerity, disapproval, or judgment in facial expression, as would be typical in face-to-face interactions. For activities such as gambling, this may be a positive benefit – particularly when losing – as no-one will actually see the face of the loser. Anonymity, like increased accessibility, may reduce social barriers to engaging in gambling, particularly skill-based gambling activities such as poker that are relatively complex and often possess tacit social etiquette. The potential discomfort of committing a structural or social faux-pas in the gambling environment because of inexperience is minimized because the individual’s identity remains concealed.

Affordability – Given the wide accessibility of the Internet, it is now relatively inexpensive to use online services on offer. Furthermore, the overall cost of has been reduced significantly through technological developments, again, rendering affordability less of a restrictive force when it comes to rationalizing involvement in the behaviour. For example, the saturation of online gambling industry has lead to increased competition, and the consumer is benefiting from the ensuing promotional offers and discounts available on gambling outlay. Regarding interactive wagering, the emergence of peer-to-peer gambling through the introduction of betting exchanges has provided punters with commission free sporting gambling odds, which in effect means the player needs to risk less money to obtain potential revenue. Finally, ancillary costs of face-to-face gambling, such as parking, tipping and purchasing refreshments, is removed when gambling within the home and therefore the overall cost of gambling is reduced making it more affordable.

Convenience – Online behaviours usually occur in the familiar and comfortable environment of home or workplace thus reducing the feeling of risk and allowing even more adventurous behaviours. For the internet user, not having to move from their home or their workplace is of great positive benefit and increases the attractiveness of online activities compared to offline activities.

Escape – For some internet users, the primary reinforcement to engage in an online behaviour is the gratification they experience online. However, the experience of activities like online gambling, online gaming and/or online sex may be reinforced through a subjectively and/or objectively experienced ‘high’ or positive change in mood state. The mood-modifying experience has the potential to provide an emotional or mental escape and further serves to reinforce the behaviour. In short, online activities can provide a potent escape from the stresses and strains of real life.

Immersion – The medium of the Internet can provide feelings of dissociation and immersion and may facilitate feelings of escape (see above). Immersion can produce lots of different types of feelings that may be reinforcing for the internet user such as losing track of time, feeling like you’re someone else, and being in a trance like state.

Interactivity – The interactivity component of the Internet can also be psychologically rewarding and different from other more passive forms of entertainment (e.g., television). The interactive nature of the Internet can therefore provide a convenient way of increasing such personal involvement that can – in online situations – lead to increased online use. Furthermore, the alternative methods of peer interaction are available within interactive online activities that retain the socially reinforcing aspects of the behaviour. Individuals can communicate via computer-mediated communication in most online activities (including gambling and gaming).

Disinhibition – The feeling of disinhibition is one of the Internet’s key appeals as there is little doubt that the Internet makes people less inhibited when they are online. Online users appear to open up more quickly online compared to offline situations and reveal themselves emotionally much faster than in the offline world. This has been referred to by Dr. John Suler as ‘hyperpersonal communication’. According to Dr. Suler, this occurs because of four features of online communication: 

  • The communicators usually share social categories so will perceive each other as similar (e.g., all online poker players)
  • The message sender can present themselves in a positive light, and so may be more confident
  • The format of online interaction (e.g., there are no other distractions, users can spend time composing messages, mix social and task messages, users don’t waste cognitive resources by answering immediately)
  • The communication medium provides a feedback loop whereby initial impressions are built upon and strengthened.

Simulation – Finally, simulations provide an ideal way in which to learn about something and which tends not to have any of the possible negative consequences. For instance, most online gambling sites have a practice mode format, where potential gamblers can place a non-monetary bet in order to see and practice the procedure of gambling on that site. Furthermore, gambling in practice modes can build self-efficacy and potentially increase perceptions of control in determining gambling outcomes motivating participation in their ‘real cash’ counterparts within the site.

More term warfare: Is the concept of ‘internet addiction’ a misnomer?

A recent study by Professor Phil Reed and his colleagues published in the Journal of Clinical Psychiatry provided some experimental evidence that internet addicts may be conditioned by what they view on the screen. Given that I was the first person in the world to publish an academic paper on internet addiction back in November 1996 it’s good to see that the number of studies into internet addiction has grown substantially over the last 20 years and that there are now hundreds of studies that have investigated the disorder worldwide in many different ways.

This newly published study is one of the few in the field that has investigated internet addiction from an experimental perspective (as opposed the majority that use self-report survey methods and the increasing number of neuroimaging studies examining what happens inside the brains of those who spend excessive amounts of time online).

Professor Reed’s study involved 100 adult volunteers who were deprived of internet access for four hours. The research team then asked the participants to name a colour (the first one that they could think of) and then gave them 15 minutes to access any websites that they wanted to on the internet. The research team monitored all the sites that the participants visited and after the 15-minute period they were again asked to think of the first colour that came to mind. The participants were also asked to complete various psychometric questionnaires including the Internet Addiction Test (IAT). The IAT is a 20-item test where each item is scored from 0 [not applicable] or 1 [rarely] up to 5 [always]. An example item is How often do you check your e-mail before something else that you need to do?” Those scoring 80 or above (out of 100) are typically defined as having a probable addiction to the internet by those who have used the IAT in previous studies.

Those classed as “high problem [internet] users” on the basis of IAT scores (and who were deprived internet access) were more likely to choose a colour that was prominent on the websites they visited during the 15-minute period after internet deprivation. This wasn’t found in those not classed as internet addicts. Professor Reed said:

“The internet addicts chose a colour associated with the websites they had just visited [and] suggests that aspects of the websites viewed after a period without the net became positively valued. Similar findings have been seen with people who misuse substances, with previous studies showing that a cue associated with any drug that relieves withdrawal becomes positively valued itself. This is the first time though that such an effect has been seen for a behavioural addiction like problematic internet usage”.

While this is an interesting finding there are some major shortcomings both from a methodological standpoint and from a more conceptual angle. Firstly, the number of high problem internet users that were deprived internet access for four hours comprised just 12 individuals so the sample size was incredibly low. Secondly, the individuals classed as high problem internet users had IAT scores ranging from 40 to 72. In short, it is highly unlikely that any of the participants were actually addicted to the internet. Thirdly, although the IAT is arguably the most used screen in the field, it has questionable reliability and validity and is now very out-dated (having been devised in 1998) and does not use the criteria suggested for Internet Disorder in the latest (fifth) edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Using more recently developed instruments such as our own Internet Disorder Scale would have perhaps overcome some of these problems.

There are also much wider problems with the use of the term ‘internet addiction’ as most studies in the field have really investigated addictions on the internet rather than to the internet. For instance, individuals addicted to online gaming, online gambling or online shopping are not internet addicts. They are gambling addicts, gaming addicts or shopping addicts that are using the medium of the internet to engage in their addictive behaviour. There are of course some activities – such as social networking – that could be argued to be a genuine type of internet addiction as such activities only take place online. However, the addiction is to an application rather than the internet itself and this should be termed social networking addiction rather than internet addiction. In short, the overwhelming majority of so-called internet addicts are no more addicted to the internet than alcoholics are addicted to the bottle.

Loud and proud: A psychological (and personal) look at the ‘Sin of Pride’

A number of years ago, I was asked to write an article on “The Sin of Pride” for the British Psychological Society. Before writing that article, I knew very little about the topic. To me it was the title of an record album by The Undertones that I bought in 1983 when I was 16 years old from Castle Records in Loughborough. I perhaps learned a bit more about it when I watched 1995 film Sevendirected by David Fincher and starring Brad Pitt (which coincidentally just happens to be one of my all-time favourite films).

After agreeing to write the article I did a bit of research on the subject (which admittedly meant I did a quick Google search followed by a more considered in-depth search on Google Scholar). While I’m no expert on the topic I can at least have a decent pub conversation about it if anyone is prepared to listen. Just to show my complete ignorance, I wasn’t even aware that the sin of pride was the sin of all sins (although I could in a pub quiz be relied upon to name the seven deadly sins).

I was asked to write on this topic because I was seen as someone who is very proud of the work that I do (and for the record, I am). However, I have often realized that just because I am proud of things that I have done in my academic career it doesn’t necessarily mean others think in the same way. In fact, on some occasions I have been quite taken aback by others’ reactions to things that I have done for which I feel justifiably proud (but more of that later).

At a very basic level, the sin of pride is rooted in a preoccupation with the self. However, in psychological terms, pride has been defined by Dr. Michael Lewis and colleagues in the International Journal of Behavioral Development as “a pleasant, sometimes exhilarating, emotion that results from a positive self-evaluation” and has been described by Dr. Jessica Tracy and her colleagues (in the journal Emotion) as one the three ‘self-conscious’ emotions known to have recognizable expressions (shame and embarrassment being the other two). From my reading of the psychological literature, it could perhaps be argued that pride has been regarded as having a more positive than negative quality, and (according to a paper in the Journal of Economic Psychology by my PhD supervisors – Professor Paul Webley and Professor Stephen Lea) is usually associated with achievement, high self-esteem and positive self-image – all of which are fundamental to my own thinking. My reading on the topic has also led to the conclusion that pride is sometimes viewed as an ‘intellectual’ or secondary emotion. In practical (and psychological) terms, sin is either a high sense of one’s personal status or ego, or the specific mostly positive emotion that is a product of praise or independent self-reflection.

One of the most useful distinctions can be made about sin (and is rooted in my own personal experience), is what Lea and Webley distinguish as ‘proper pride’ and ‘false pride’. They claim that:

“Proper pride is pride in genuine achievements (or genuine good qualities) that are genuinely one’s own. False pride is pride in what is not an achievement, or not admirable, or does not properly belong to oneself. Proper pride is associated with the desirable property of self-esteem; false pride with vanity or conceit. Proper pride is associated with persistence, endurance and doggedness; false pride with stubbornness, obstinacy and pig-headedness.”

As I noted above, there have been times when I have been immensely proud of doing something only for friends and colleagues to be appalled. ‘Proper pride’ as Lea and Webley would argue. One notable instance was when I wrote a full-page article for The Sun on ‘internet addiction’ published in August 1997. I originally wanted to be a journalist before I became a psychologist, and my journalist friends had always said that to get a full-page ‘by line’ in the biggest selling newspaper in the UK was a real achievement. I was immensely proud – apart from the headline that a sub-editor had dubbed my piece ‘The Internuts’ – and showed the article to whoever was around.

I had always passionately argued (and still do) that I want my research to be disseminated and read by as many people as possible. What was better than getting my work published in an outlet with (at the time) 10 million readers? My elation was short-lived. One close colleague and friend was very disparaging and asked how I could stoop so low as to “write for the bloody Sun?” Similar comments came from other colleagues and I have to admit that I was put off writing for the national tabloids for a number of years. (However, I am now back writing regularly for the national dailies and am strong enough to defend myself against the detractors).

In 2006, I was invited to the House of Commons by the ex-Leader of the Conservative Party, Iain Duncan-Smith and invited to Chair his Centre For Social Justice Working Party on Gambling and write a report as part of the Conservative Party’s ‘Breakdown Britain’ initiative. Anyone who knows me will attest that my political leanings are left of centre and that I working with the Conservatives on this issue was not something I did without a lot of consideration. I came to the conclusion that gambling was indeed a political issue (rather than a party political issue) and if the Conservative Party saw this as an important issue, I felt duty bound to help given my research experience in the area. I spent a number of months working closely with Iain Duncan-Smith’s office and when the report was published I was again very proud of my achievement.

However, as soon as the report came out I received disbelieving and/or snide emails asking how I could have “worked with the Conservatives”. I have spent years trying to put the psychosocial impact of gambling on the political agenda. If I am offered further opportunities by those with political clout, I won’t think twice about taking them. I am still immensely proud of such actions despite what others may think.

Pride is ultimately a subjective experience and the two personal experiences that I outlined above will not put me off doing what I want to do. I shall continue to engage in activities where I think my work can have an impact and shall work with (and write for) those that can help me disseminate my research findings to as many people as possible.

Tech your time: 12 top tips for a digital detox

Over the last few years there has been increasing use of the term ‘digital detox’. According to the Oxford Dictionary, digital detox is a period of time during which a person refrains from using electronic devices such as smartphones or computers, regarded as an opportunity to reduce stress or focus on social interaction in the physical world”. I have to admit that I often find it hard to switch off from work (mainly because I love my job). Given that my job relies on technology, by implication it also means I find it hard to switch off from technology. Today’s blog is as much for me as anyone reading this and provides some tips on how to cut down on technology use, even if it’s just for the weekend or a holiday. I have compiled these tips from many different online articles as well as some of my own personal strategies. 

Digitally detox in increments: For some people, going a few minutes without checking their smartphone or emails is difficult. For many, the urge is reflexive and habitual. If you are one of those people, then ‘baby steps’ are needed. Such individuals need to learn to digitally detox in small increments (i.e., go on a ‘digital diet’). Start by proving to yourself that you can go 15 minutes without technology. Over time, increase the length of time without checking (say) Twitter, Facebook and emails (e.g., 30 minutes, 60 minutes, a couple of hours) until you get into a daily habit of being able to spend a few hours without the need to be online. Another simple trick is to only keep mobile devices partially topped up. This means users have to be sparing when checking their mobile devices.

Set aside daily periods of self-imposed non-screen time: One of the secrets to cutting down technology use to acceptable levels is to keep aside certain times of the day technology-free (meal times and bedtime are a good starting place – in fact, these rooms should be made technology-free). For instance, I rarely look at any emails between 6pm and 8pm as this is reserved for family time (e.g., cooking and eating dinner with the family). Another strategy to try is having a technology-free day at the weekends (e.g., not accessing the internet at all for 24 hours). However, watching television or using an e-reader is fine. Another simple strategy is to have technology-free meal times (at both home and work). Don’t bring your smartphone or tablet to the table.

Only respond to emails and texts at specific times of the day: Only a few individuals are ‘on call’ and have to assume that the message they receive will be an emergency. Looking at emails (say) just three times a day (9am, 1pm, 4pm) will save lots of time in the long run. Turning off email and social media, disabling push notifications, or simply turning the volume setting to silent on electronic devices will also reduce the urge to constantly check mobile devices.

Don’t use your smartphone or tablet as an alarm clock: By using a standard alarm clock to wake you in the morning, you will avoid the temptation to look at emails and texts just as you are about to go to sleep or just wake up (or in the middle of the night if you are a workaholic!).

Engage in out-of-work activities where it is impossible (or frowned upon) to use technology: Nowadays, leisure activities such as going to the pub, having a meal, or going to the cinema, don’t stop people using wireless technology. By engaging in digitally incompatible activities where it is impossible to access technology simultaneously (e.g., jogging, swimming, meditation, outdoor walks in wi-fi free areas) or go to places where technology is frowned upon (e.g., places of worship, yoga classes, etc.) and individual will automatically decrease the amount of screen time. In social situations, you can turn people’s need to check their phones into a game. For instance, in the pub, you could have a game where the first one to check their phone has to buy a round of drinks for everyone else.

Tell your work colleagues and friends you are going on a digital detox: Checking emails and texts can become an almost compulsive behaviour because of what psychologists have termed ‘FOMO’ (fear of missing out) that refers to the anxiety that an interesting or exciting event may be happening elsewhere online. By telling everyone you know that you will not be online for a few hours, they will be less likely to contact you in the first place and you will be less likely check for online messages in the first place. Alternatively, Put your ‘out-of-office’ notification on for a few hours and do something more productive with your time.

Reduce your contact lists: One way to spend less time online is to reduce the number of friends on social networking sites, stop following blogs (but not mine, of course!), delete unused apps, and unsubscribe from online groups that have few benefits. Also, delete game apps that can be time-consuming (e.g., Angry Birds, Candy Crush Saga, etc.).

Get a wristwatch: One of the most common reasons for looking at a smartphone or a tablet is to check the time. If checking the time also leads to individuals noticing they have a text, email or tweet, they will end up reading what has been sent. By using an old fashioned wristwatch (as opposed to new smart watches like the Apple Watch), the urge to reply to messages will decrease.

Think about the benefits of not constantly being online: If you are the kind of person that responds to emails, texts and tweets as they come in, you will write longer responses than if you look at them all in a block. The bottom line is that you can save loads of time to spend on other things if you didn’t spend so long constantly reacting to what is going on in the online world.

Enjoy the silence: Too many people fail to appreciate being in the moment and allowing themselves to resist the urge to log onto their laptops, mobiles and tablets. It is at these times that some people might interpret as boredom that we can contemplate and be mindful. This could be made more formal by introducing meditation into a daily routine. There are also many places that run whole weekends and short breaks where technology is forbidden and much of the time can be spent in quiet contemplation. 

Fill the void: To undergo digital detox for any length of time, an individual has to replace the activity with something that is as equally rewarding (whether it is physically, psychologically or spiritually). When I’m on holiday, I catch up on all the novels that I’ve been meaning to read. In shorter spaces of time (such as sitting in boring meetings) I doodle, write ‘to do’ lists, generate ideas to write about, or simply do nothing (and be mindful, aware of the present moment). In short, I try to productive (or unproductive) without having to resort to my technology. 

Use technology to beat technology: One thing that can shock technology users is how much time they actually spend on their mobile devices. Working out how much time is actually spent online can be the first step in wanting to cut down. (For instance, someone I once worked with was shocked to find he had spent 72 [24-hour] days in one year playing World of Warcraft). Tech users can download apps that tell them how much time spending online, (e.g., Moment). Being made aware of a problem is often the first step in enabling behavioural change.

Game over-view: A brief overview of our recent papers on gaming addiction

Following my recent blogs where I outlined some of the papers that my colleagues and I have published on mindfulness and Internet addiction, here is a round-up of recent papers that my colleagues and I have published on gaming addiction.

Pontes, H. & Griffiths, M.D. (2015). Measuring DSM-5 Internet Gaming Disorder: Development and validation of a short psychometric scale. Computers in Human Behavior, 45, 137-143.

  • Despite the large growth on gaming behaviour research, little has been done to overcome the problem stemming from the heterogeneity of gaming addiction nomenclature and the use of non-standardised measurement tools. Following the recent inclusion of Internet Gaming Disorder [IGD] as a condition worthy of future studies in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders [DSM-5], researchers have now an opportunity to reach consensus and unification in the field. The aim of this study was to develop a new nine-item short-form scale to assess Internet Gaming Disorder (IGDS-SF9) and to further explore its psychometric properties. A sample of 1060 gamers (85.1% males, mean age 27 years) recruited via online gaming forums participated. Exploratory factor analysis [EFA], confirmatory factor analysis [CFA], analyses of the criterion-related and concurrent validity, reliability, standard error of measurement [SEM], population cross-validity, and floor and ceiling effects were performed to assess the instrument’s psychometric properties. The results from the EFA revealed a single-factor structure for IGD that was also confirmed by the CFA. The nine items of the IGDS-SF9 are valid, reliable, and proved to be highly suitable for measuring IGD. It is envisaged that the IGDS-SF9 will help facilitate unified research in the field.

Benrazavi, S.R., Teimouri, M. & Griffiths, M.D. (2015). Utility of parental mediation model on youth’s problematic online gaming. International Journal of Mental Health and Addiction, 13, 712-727.

  • The Parental Mediation Model (PMM) was initially designed to regulate children’s attitudes towards the traditional media. In the present era, because of prevalent online media there is a need for similar regulative measures. Spending long hours on social media and playing online games increase the risks of exposure to the negative outcomes of online gaming. This paper initially applied the PMM developed by European Kids Online to (i) test the reliability and validity of this model and (ii) identify the effectiveness of this model in controlling problematic online gaming (POG). The data were collected from 592 participants comprising 296 parents and 296 students of four foreign universities, aged 16 to 22 years in Kuala Lumpur (Malaysia). The study found that the modified model of the five-factor PMM (Technical mediation, Monitoring mediation, Restrictive mediation, Active Mediation of Internet Safety, and Active mediation of Internet Use) functions as a predictor for mitigating POG. The findings suggest the existence of a positive relation between ‘monitoring’ and ‘restrictive’ mediation strategies and exposure to POG while Active Mediation of Internet Safety and Active mediation of Internet use were insignificant predictors. Results showed a higher utility of ‘technical’ strategies by the parents led to less POG. The findings of this study do not support the literature suggesting active mediation is more effective for reducing youth’s risky behaviour. Instead, parents need to apply more technical mediations with their children and adolescents’ Internet use to minimize the negative effects of online gaming.

Hussain, Z., Williams, G. & Griffiths, M.D. (2015). An exploratory study of the association between online gaming addiction and enjoyment motivations for playing massively multiplayer online role-playing games. Computers in Human Behavior, 50, 221–230.

  • Massively multiplayer online role-playing games (MMORPGs) are a popular form of entertainment used by millions of gamers worldwide. Potential problems relating to MMORPG play have emerged, particularly in relation to being addicted to playing in such virtual environments. In the present study, factors relating to online gaming addiction and motivations for playing in MMORPGs were examined to establish whether they were associated with addiction. A sample comprised 1167 gamers who were surveyed about their gaming motivations. Latent Class Analysis revealed seven classes of motivations for playing MMORPGs, which comprised: (1) novelty; (2) highly social and discovery-orientated; (3) aggressive, anti-social and non-curious; (4) highly social, competitive; (5) low intensity enjoyment; (6) discovery-orientated; and (7) social classes. Five classes of gaming addiction-related experiences were extracted including: (1) high risk of addiction, (2) time-affected, (3) intermediate risk of addiction, (4) emotional control, and (5) low risk of addiction classes. Gender was a significant predictor of intermediate risk of addiction and emotional control class membership. Membership of the high risk of addiction class was significantly predicted by belonging to a highly social and competitive class, a novelty class, or an aggressive, anti-social, and non-curious class. Implications of these findings for assessment and treatment of MMORPG addiction are discussed.

Király, O., Griffiths, M.D. & Demetrovics Z. (2015). Internet gaming disorder and the DSM-5: Conceptualization, debates, and controversiesCurrent Addiction Reports, 2, 254–262.

  • Scientific interest in behavioral addictions (such as Internet gaming disorder [IGD]) has risen considerably over the last two decades. Moreover, the inclusion of IGD in Section 3 of DSM-5 will most likely stimulate such research even more. Although the inclusion of IGD appears to have been well received by most of the researchers and clinicians in the field, there are several controversies and concerns surrounding its inclusion. The present paper aims to discuss the most important of these issues: (i) the possible effects of accepting IGD as an addiction; (ii) the most important critiques regarding certain IGD criteria (i.e., preoccupation, tolerance, withdrawal, deception, and escape); and (iii) the controversies surrounding the name and content of IGD. In addition to these controversies, the paper also provides a brief overview of the recent findings in the assessment and prevalence of IGD, the etiology of the disorder, and the most important treatment methods.

Király, O., Urbán, R., Griffiths, M.D., Ágoston, C., Nagygyörgy, K., Kökönyei, G. & Demetrovics, Z. (2015). Psychiatric symptoms and problematic online gaming: The mediating effect of gaming motivation. Journal of Medical Internet Research, 17(4) :e88.

  • Background: The rapid expansion of online video gaming as a leisure time activity has led to the appearance of problematic online gaming (POG). According to the literature, POG is associated with different psychiatric symptoms (eg, depression, anxiety) and with specific gaming motives (ie, escape, achievement). Based on studies of alcohol use that suggest a mediator role of drinking motives between distal influences (e.g., trauma symptoms) and drinking problems, this study examined the assumption that there is an indirect link between psychiatric distress and POG via the mediation of gaming motives. Furthermore, it was also assumed that there was a moderator effect of gender and game type preference based on the important role gender plays in POG and the structural differences between different game types. Objective: This study had two aims. The first aim was to test the mediating role of online gaming motives between psychiatric symptoms and problematic use of online games. The second aim was to test the moderator effect of gender and game type preference in this mediation model. Methods: An online survey was conducted on a sample of online gamers (N=3186; age: mean 21.1, SD 5.9 years; male: 2859/3186, 89.74%). The Brief Symptom Inventory (BSI), the Motives for Online Gaming Questionnaire (MOGQ), and the Problematic Online Gaming Questionnaire (POGQ) were administered to assess general psychiatric distress, online gaming motives, and problematic online game use, respectively. Structural regression analyses within structural equation modeling were used to test the proposed mediation models and multigroup analyses were used to test gender and game type differences to determine possible moderating effects. Results: The mediation models fitted the data adequately. The Global Severity Index (GSI) of the BSI indicated that the level of psychiatric distress had a significant positive direct effect (standardized effect=.35, P<.001) and a significant indirect (mediating) effect on POG (standardized effect=.194, P<.001) via 2 gaming motives: escape (standardized effect=.139, P<.001) and competition (standardized effect=.046, P<.001). The comparison of the 2 main gamer types showed no significant differences in the model. However, when comparing male and female players it was found that women had (1) slightly higher escape scores (on a 5-point Likert scale: mean 2.28, SD 1.14) than men (mean 1.87, SD 0.97) and (2) a stronger association between the escape motive and problematic online gaming (standardized effect size=.64, P<.001) than men (standardized effect size=.20, P=.001). Conclusions: The results suggest that psychiatric distress is both directly and indirectly (via escape and competition motives) negatively associated with POG. Therefore, the exploration of psychiatric symptoms and gaming motives of POG can be helpful in the preparation of prevention and treatment programs.

  • In recent years, problematic and addictive gaming has been a phenomenon of growing concern worldwide. In light of the increasing awareness about this issue, the latest (fifth) edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-5) included Internet Gaming Disorder (IGD) as an area in need of more empirical research. The Internet Gaming Disorder Test (IGD-20 Test) was developed as a valid and reliable tool to assess IGD. The aim of the present study was to validate the Spanish version of the IGD-20 Test, and analyze the different profiles found among a sample of 1074 Spanish-speaking gamers. A confirmatory factor analysis showed the validity of the Spanish version of the IGD-20 Test and its six factor structure (i.e., salience, mood modification, tolerance, withdrawal, conflict and relapse). The latent profile analysis (LPA) showed five different gamer classes. The ‘disordered gamers’ class comprised 2.6% of the participants. Based on this class, sensitivity and specificity analyses showed an adequate empirical cut-off point of 75 (out of 100). It is concluded that the Spanish version of the IGD-20 Test is valid and reliable and can be used in research into IGD among Spanish speaking populations.

  • This commentary paper critically discusses the recent debate paper by Petry et al. (2014) that argued there was now an international consensus for assessing Internet Gaming Disorder (IGD). Our collective opinions vary considerably regarding many different aspects of online gaming. However, we contend that the paper by Petry and colleagues does not provide a true and representative international community of researchers in this area. This paper critically discusses and provides commentary on (i) the representativeness of the international group that wrote the ‘consensus’ paper, and (ii) each of the IGD criteria. The paper also includes a brief discussion on initiatives that could be taken to move the field towards consensus. It is hoped that this paper will foster debate in the IGD field and lead to improved theory, better methodologically designed studies, and more robust empirical evidence as regards problematic gaming and its psychosocial consequences and impact.

Characteristics and psychiatric symptoms of Internet Gaming Disorder among adults using self-reported DSM-5 criteria. Psychiatry Investigation, 13(1), 58-66.

  • Objective: The Section III of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) proposed nine diagnostic criteria and five cut-point criteria for Internet Gaming Disorder (IGD). We aimed to examine the efficacy of such criteria. Methods: Adults (n=3041, men: 1824, women: 1217) who engaged in internet gaming within last 6 months completed a self-report online survey using the suggested wordings of the criteria in DSM-5. Major characteristics, gaming behavior, and psychiatric symptoms of IGD were analyzed using ANOVA, chi-square, and correlation analyses. Results: The sociodemographic variables were not statistically significant between the healthy controls and the risk group. Among the participants, 419 (13.8%) were identified and labeled as the IGD risk group. The IGD risk group scored significantly higher on all motivation subscales (p<0.001). The IGD risk group showed significantly higher scores than healthy controls in all nine psychiatric symptom dimensions, i.e., somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism (p<0.001). Conclusion: The IGD risk group showed differential psychopathological manifestations according to DSM-5 IGD diagnostic criteria. Further studies are needed to evaluate the reliability and validity of the specific criteria, especially for developing screening instruments.

Net gains: A brief overview of our recent papers on Internet addiction

Following my recent blogs where I outlined some of the papers that I and my colleagues have published on mindfulness, I got a couple of emails asking if I could do the same thing on other areas that we have been researching into. So, here it is.

Pontes, H.M., Szabo, A. & Griffiths, M.D. (2015). The impact of Internet-based specific activities on the perceptions of Internet Addiction, Quality of Life, and excessive usage: A cross-sectional study. Addictive Behaviors Reports, 1, 19-25.

  • Introduction: Recent research has examined the context in which preference for specific online activities arises, leading researchers to suggest that excessive Internet users are engaged in specific activities rather than ‘generalized’ Internet use. The present study aimed to partially replicate and expand these findings by addressing four research questions regarding (i) participants’ preferred online activities, (i) possible expected changes in online behavior in light of hypothetical scenarios, (iii) perceived quality of life when access to Internet was not possible, and (iv) how participants with self-diagnosed Internet addiction relate to intensity and frequency of Internet use. Methods: A cross-sectional design was adopted using convenience and snowball sampling to recruit participants. A total of 1057 Internet users with ages ranging from 16 to 70 years (Mean age= 30 years, SD = 10.84) were recruited online via several English-speaking online forums. Results: Most participants indicated that their preferred activities were (i) accessing general information and news, (ii) social networking, and (iii) using e-mail and/or online chatting. Participants also reported that there would be a significant decrease of their Internet use if access to their preferred activities was restricted. The study also found that 51% of the total sample perceived themselves as being addicted to the Internet, while 14.1% reported that without the Internet their life would be improved. Conclusions: The context in which the Internet is used appears to determine the intensity and the lengths that individuals will go to use this tool. The implications of these findings are further discussed.

  • Research into Internet addiction (IA) has grown rapidly over the last decade. The topic has generated a great deal of debate, particularly in relation to how IA can be defined conceptually as well as the many methodological limitations. The present review aims to further elaborate and clarify issues that are relevant to IA research in a number of areas including: definition and characterization, incidence and prevalence rates, associated neuronal processes, and implications for treatment, prevention, and patient-specific considerations. It is concluded that there is no consensual definition for IA. Prevalence rates among nationally representative samples across several countries vary greatly (from 1% to 18.7%), most likely reflecting the lack of methodological consistency and conceptual rigor of the studies. The overlaps between IA and other more traditional substance-based addictions and the possible neural substrates implicated in IA are also highlighted. In terms of treatment and prevention, both psychological and pharmacological treatments are examined in light of existing evidence alongside particular aspects inherent to the patient perspective. Based on the evidence analyzed, it is concluded that IA may pose a serious health hazard to a minority of people.

Measurement invariance of Internet Addiction Test among Hong Kong, Japanese, and Malaysian adolescents: An item response analysis. Cyberpsychology, Behavior and Social Networking, 18, 609-617.

  • There has been increased research examining the psychometric properties on the Internet Addiction Test (IAT) in different populations. This population-based study examined the psychometric properties and measurement invariance of the IAT in adolescents from three Asian countries. In the Asian Adolescent Risk Behavior Survey (AARBS), 2,535 secondary school students (55.9% girls) aged 12-18 years from Hong Kong (n=844), Japan (n=744), and Malaysia (n=947) completed a survey in 2012-2013 school year. A nested hierarchy of hypotheses concerning the IAT cross-country invariance was tested using multigroup confirmatory factor analyses. Replicating past findings in Hong Kong adolescents, the construct of the IAT is best represented by a second-order three-factor structure in Malaysian and Japanese adolescents. Configural, metric, scalar, and partial strict factorial invariance was established across the three samples. No cross-country differences on Internet addiction were detected at the latent mean level. This study provided empirical support for the IAT as a reliable and factorially stable instrument, and valid to be used across Asian adolescent populations.

  • Kimberly Young’s initial work on Internet addiction (IA) was pioneering and her early writings on the topic in- spired many others to carry out research in the area. Young’s (2015) recent paper on the ‘evolution of Internet addiction’ featured very little European research, and did not consider the main international evidence that has contributed to our current knowledge about the conceptualization, epidemiology, etiology, and course of Internet-related disorders. This short commentary paper elaborates on important literature omitted by Young that the present authors believe may be of use to researchers. We also address statements made in Young’s (2015) commentary that are incorrect (and therefore misleading) and not systematically substantiated by empirical evidence.

Stavropoulos, V., Kuss, D.K., Griffiths, M.D. & Motti-Stafanidi, F. (2016). A longitudinal study of adolescent internet addiction: The role of conscientiousness and classroom hostility. Journal of Adolescent Research, in press.

  • Over the last decade, research on Internet addiction (IA) has increased. However, almost all studies in the area are cross-sectional and do not examine the context in which Internet use takes place. Therefore, a longitudinal study examined the role of conscientiousness (as a personality trait) and classroom hostility (as a contextual factor) in the development of IA. The participants comprised 648 adolescents and were assessed over a 2-year period (while aged 16-18 years). A three-level hierarchical linear model was carried out on the data collected. Findings revealed that (a) lower conscientiousness was associated with IA and this did not change over time and (b) although being in a more hostile classroom did not initially have a significant effect, it increased girls’ IA vulnerability over time and functioned protectively for boys. Results indicated that the contribution of individual and contextual IA factors may differ across genders and over time. More specifically, although the protective effect of conscientiousness appeared to hold, the over-time effect of classroom hostility increased the risk of IA for girls. These findings are discussed in relation to the psychological literature. The study’s limitations and implications are also discussed.

Internet addiction and its psychosocial risks (depression, anxiety, stress and loneliness) among Iranian adolescents and young adults: A structural equation model in a cross-sectional study. International Journal of Mental Health and Addiction, in press.

  • Internet addiction has become an increasingly researched area in many Westernized countries. However, there has been little research in developing countries such as Iran, and when research has been conducted, it has typically utilized small samples. This study investigated the relationship of Internet addiction with stress, depression, anxiety, and loneliness in 1052 Iranian adolescents and young adults. The participants were randomly selected to complete a battery of psychometrically validated instruments including the Internet Addiction Test, Depression Anxiety Stress Scale, and the Loneliness Scale. Structural equation modeling and Pearson correlation coefficients were used to determine the relationship between Internet addiction and psychological impairments (depression, anxiety, stress and loneliness). Pearson correlation, path analysis, multivariate analysis of variance (MANOVA), and t-tests were used to analyze the data. Results showed that Internet addiction is a predictor of stress, depression, anxiety, and loneliness. Findings further indicated that addictive Internet use is gender sensitive and that the risk of Internet addiction is higher in males than in females. The results showed that male Internet addicts differed significantly from females in terms of depression, anxiety, stress, and loneliness. The implications of these results are discussed.

Myth world: Addictive personality does not exist

(Please note: This article is a slightly expanded and original version of an article that was first published in The Conversation).

“Life is a series of addictions and without them we die”. This is my favourite quote in the academic addiction literature and was made back in 1990 in the British Journal of Addiction by Professor Isaac Marks. This deliberately provocative and controversial statement was made to stimulate debate about whether excessive and potentially problematic activities such as gambling, sex and work can really be classed as genuine addictive behaviours. Many of us might say to ourselves that we are ‘addicted’ to tea or coffee, our work, or know others who we might describe as having addictions watching the television or using pornography. But is this really true?

The issue all comes down to how addiction is defined in the first place as many of us in the field disagree on what the core components of addiction are. Many would argue that the word ‘addiction’ or ‘addictive’ is used so much in everyday circumstances that word has become meaningless. For instance, saying that a book is an ‘addictive read’ or that a specific television series is ‘addictive viewing’ renders the word useless in a clinical setting. Here the word ‘addictive’ is arguably used in a positive way and as such it devalues the real meaning of the word.

The question I get asked most – particularly by the broadcast media – is what is the difference between a healthy excessive enthusiasm and an addiction and my response is simple – a healthy excessive enthusiasm adds to life whereas an addiction takes away from it. I also believe that to be classed as an addiction, any such behaviour should comprise a number of key components including overriding preoccupation with the behaviour, conflict with other activities and relationships, withdrawal symptoms when unable to engage in the activity, an increase in the behaviour over time (tolerance), and use of the behaviour to alter mood state. Other consequences such as feeling out of control with the behaviour and cravings for the behaviour are often present. If all these signs and symptoms are present I would call the behaviour a true addiction. However, that hasn’t stopped others accusing me of ‘watering down’ the concept of addiction.

A few years ago, Dr. Steve Sussman, Nadra Lisha and I published a large and comprehensive review in the journal Evaluation and the Health Professions examining the co-relationship between eleven different potentially addictive behaviours reported in the academic literature (smoking tobacco, drinking alcohol, taking illicit drugs, eating, gambling, internet use, love, sex, exercise, work, and shopping). We examined the data from 83 large-scale studies and reported an overall 12-month prevalence of an addiction among U.S. adults varies from 15% to 61%. We also reported it plausible that 47% of the U.S. adult population suffers from maladaptive signs of an addictive disorder over a 12-month period, and that it may be useful to think of addictions as due to problems of lifestyle as well as to person-level factors. In short – and with many caveats – our paper argued that at any one time almost half the US population are addicted to one or more behaviours.

There is a lot of scientific literature showing that having one addiction increases the propensity to have other co-occurring addictions. For instance, in my own research I have come across alcoholic pathological gamblers and we can all probably think of individuals that we might describe as caffeine-addicted workaholics. It is also very common for individuals that give up one addiction to replace it with another (which we psychologists call ‘reciprocity’). This is easily understandable as when an individual gives up one addiction it leaves a large hole in the waking lives (often referred to as the ‘void’) and often the only activities that can fill the void and give similar experiences are other potentially addictive behaviours. This has led many people to describe such people as having an ‘addictive personality’.

While there are many pre-disposing factors for addictive behaviour including genetic factors and psychological personality traits such as high neuroticism (anxious, unhappy, prone to negative emotions) and low conscientiousness (impulsive, careless, disorganised), I would argue that ‘addictive personality’ is a complete myth. Even though there is good scientific evidence that most people with addictions are highly neurotic, neuroticism in itself is not predictive of addiction (for instance, there are individuals who are highly neurotic but are not addicted to anything so neuroticism is not predictive of addiction). In short, there is no good evidence that there is a specific personality trait (or set of traits) that is predictive of addiction and addiction alone.

Doing something habitually or excessively does not necessarily make it problematic. While there are many behaviours such as drinking too much caffeine or watching too much television that could theoretically be described as addictive behaviours, they are more likely to be habitual behaviours that are important in an individual’s life but actually cause little or no problems. As such, these behaviours should not be described as an addiction unless the behaviour causes significant psychological and/or physiological effects in their day-to-day lives.

Playing the field: Another look at Internet Gaming Disorder

Research into online addictions has grown considerably over the last two decades and much of it has concentrated on problematic gaming, particularly MMORPGs (Massively Multiplayer Online Role-Playing Games). In the latest (fifth) edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013), Internet Gaming Disorder (IGD) (also commonly referred in the literature as problematic gaming and gaming addiction) was included in Section 3 (‘Emerging Measures and Models’) as a promising area that needed future research before being included in the main section of future editions of the DSM.

The DSM-5 proposed nine criteria for IGD (of which five or more need to be endorsed over the period of 12 months and result in clinically significant impairment to be diagnosed as experiencing IGD). More specifically the criteria include (1) preoccupation with games; (2) withdrawal symptoms when gaming is taken away; (3) the need to spend increasing amounts of time engaged in gaming, (4) unsuccessful attempts to control participation in gaming; (5) loss of interest in hobbies and entertainment as a result of, and with the exception of, gaming; (6) continued excessive use of games despite knowledge of psychosocial problems; (7) deception of family members, therapists, or others regarding the amount of gaming; (8) use of gaming to escape or relieve a negative mood;  and (9) loss of a significant relationship, job, or educational or career opportunity because of participation in games.

There is no agreement on the prevalence of IGD as the vast majority of studies have surveyed non-representative self-selected samples using over 20 different screening instruments. A review of problematic gaming prevalence studies that I published with Orsi Király, Halley Pontes, and Zsolt Demetrovics (in the 2015 book Mental Health in the Digital Age: Grave Dangers, Great Promise) reported a large variation in the prevalence rates (from 0.2% up to 34%). However, we noted that there were many factors that could have accounted for the wide variation in prevalence rates including the type of gaming examined (i.e., some studies just examined online gaming, whereas others examined console gaming or a mixture of both), sample size, participants’ age range, participant type (i.e., some surveyed the general population while others assessed gamers only), and instruments used to assess gaming.

There have been a handful of studies that have reported the prevalence of IGD using nationally representative samples. The prevalence rates reported were 8.5% of American youth aged 8–18 years, 1.2% of German adolescents aged 13-18 years, 5.5% among Dutch adolescents aged 13-20, and 5.4% among Dutch adults, 4.3% of Hungarian adolescents aged 15-16 years, 1.4% of Norwegian gamers, and 1.6% of European youth from seven countries aged 14-17 years.

There are now over 20 different screening instruments including a number of new ones specifically incorporating the IGD criteria (including a number that I have co-developed with Halley Pontes). The multiplicity of problematic gaming screens remains a key challenge in the field and partially reflects the lack of consensus in terms of the assessment of the phenomenon. A comprehensive 2013 review that I published with Daniel King and others in Clinical Psychology Review examined the criteria of 18 problematic gaming screens. The 18 screens had been utilized in 63 quantitative studies (N=58,415 participants). The main weaknesses identified were (i) inconsistency of core addiction indicators across studies, (ii) a general lack of any temporal dimension, (iii) inconsistent cutoff scores relating to clinical status, (iv) poor and/or inadequate inter-rater reliability and predictive validity, and (v) inconsistent and/or untested dimensionality. We also questioned the appropriateness of certain screens for certain settings, because those used in clinical practice may require a different emphasis than those used in epidemiological, experimental, or neurobiological research settings.

Research into IGD is needed from clinical, epidemiological, and neurobiological aspects of IGD. There has been an increasing number of neurobiological studies on IGD and a 2014 meta-analysis by Dr. Y. Meng and colleagues in Addiction Biology of 10 neuroimaging studies investigating the functional brain response to cognitive tasks from IGD using quantitative effect size signed differential mapping meta-analytic methods. found reliable clusters of abnormal activation in IGD within the regions comprising the bilateral medial frontal gyrus/cingulate gyrus, the left middle temporal gyrus and fusiform gyrus when compared to healthy controls. The same review also found that greater amounts of time spent per week playing was associated with hyper-activity in the left medial frontal gyrus and the right cingulate gyrus. Despite the useful findings reported, one of the major limitations of this meta-analysis was that 90% of the studies reviewed were conducted in Asian countries or regions, which might be problematic since prevalence rates of IGD in these populations are usually inflated compared to prevalence rates reported in Western countries. Furthermore, a systematic review of neuroimaging studies examining Internet addiction (IA) and IGD by Daria Kuss and myself in the journal Brain Sciences concluded that:

“These studies provide compelling evidence for the similarities between different types of addictions, notably substance-related addictions and Internet and gaming addiction, on a variety of levels. On the molecular level, Internet addiction is characterized by an overall reward deficiency that entails decreased dopaminergic activity. On the level of neural circuitry, Internet and gaming addiction lead to neuroadaptation and structural changes that occur as a consequence of prolonged increased activity in brain areas associated with addiction. On a behavioral level, Internet and gaming addicts appear to be constricted with regards to their cognitive functioning in various domains”

Over the last decade, a number of studies have investigated the association between IGD (and its derivatives) and various personality and comorbidity factors. Our recent review in the book Mental Health in the Digital Age: Grave Dangers, Great Promise summarized the research examining the relationship between personality traits and IGD. Empirical studies have shown IGD to be associated with (i) neuroticism, (ii) aggression and hostility, (iii) avoidant and schizoid tendencies, loneliness and introversion, (iv) social inhibition, (v) boredom inclination, (vi) sensation-seeking, (vii) diminished agreeableness, (viii) diminished self-control and narcissistic personality traits, (ix) low self-esteem, (x) state and trait anxiety, and (xi) low emotional intelligence. However, we noted that it was difficult to assess the aetiological significance of such associations because these personality factors are not unique to problematic gaming. Our review also reported that IGD had been associated with various comorbid disorders, including (i) attention deficit hyperactivity disorder, (ii) symptoms of generalized anxiety disorder, panic disorder, depression, and social phobia, and (iii) various psychosomatic symptoms.

According to a 2013 editorial in the journal Addiction, Nancy Petry and Charles O’Brien (2013), IGD will not be included as a separate mental disorder in future editions of the DSM until the (i) defining features of IGD have been identified, (ii) reliability and validity of specific IGD criteria have been obtained cross-culturally, (iii) prevalence rates have been determined in representative epidemiological samples across the world, and (iv) aetiology and associated biological features have been evaluated.
