The sciences of reliances on appliances: Have we become reliant on digital technologies and what can we do about it?

Readers of my blog will know that I hate to waste anything that I have put time and effort into and today’s blog contain the written transcripts of partly unpublished interviews on smartphone and social media use that I did a number of months ago with the Daily Express and the Nottingham Post. I have no idea which parts of my responses were used or in what context, but here my complete responses to the questions I was asked.

Q: Are we too reliant on tech and gadgets when it comes to family life both in the home, and also social media?

Mark Griffiths: In most walks of life including work, education, and leisure, reliance on tech and gadgets has become the norm. It’s almost impossible to function without relying on tech. However, individuals often spend too much time on things that distract them from what they should be doing. I use social media every day but for no more than about 10-15 minutes so it doesn’t interfere with work productivity or time spent with my family. Most individuals are habitual smartphone and/or social media users. Even though very few people are genuinely addicted to the applications on their smartphones, a few hours use each day can reduce the amount of time they should be spending on their occupation or education (depending upon age) and can reduce the amount of quality time spent with family members. I have three screenagers all who spend a disproportionate amount of time in front of their smartphones. However, I have no problem if it doesn’t impact on their education, chores around the house, social friendships with their peers, or their physical education. However, some parents use tech heavily themselves (which is not good in terms of being a role model to their children) and others use tech as electronic ‘babysitters’ for their children.

Q: What problems can this cause?

MG: Thankfully, serious side effects and genuine addiction to smartphone applications is minimal. However, habitual smartphone use simply leads to less time spent on things that people should be doing including their (i) job or school/ college/ university work, (ii) physical exercise (because smartphone use tends to be a sedentary for most people), and (iii) quality time with friends and family (less face-to-face interaction). For those at risk of genuine addiction, excessive smartphone use leads to a complete deterioration and compromising of everything in that person’s life and can lead to mental health issues (e.g., depression, social anxiety, etc.) but as I said the number of individuals genuinely affected in this way is minimal.

Q: What are the benefits of a more simple life, less gadgets, less tech?

MG: I gave up using my smartphone a couple of years ago and am highly productive in my job. I still actively use social media and am online a lot of the time but doing it via my laptop or work computer means that I’m not constantly bombarded with notifications, pings by the minute, or constant phone vibrations. The benefits of technology far outweigh the negatives but that doesn’t mean that we should be living our whole lives online.

Q: What are your top tips for switching off as a family 

MG: I’ve written a lot about the benefits of digital detox and how to so it (see: https://drmarkgriffiths.wordpress.com/2016/04/26/tech-your-time-12-top-tips-for-a-digital-detox/ ). As a father of three screenagers we have some general rules:

  • No smartphones at the dinner table.
  • No smartphone use late at night (can’t do that now as my children are now al over 18 years of age) but parents have every right to control their younger children’s tech use.
  • No smartphones for children under 11 years of age.
  • Remember that what you do with tech will be mimicked by your children so set a good example of responsible tech use.
  • Having family events where smartphone use is difficult (e.g., going swimming, going for outdoor walks where reception is poor, going on holiday in places where there is no Wi-Fi access). These types of event are more about showing children that life can still live life without being online 24/7. All my children are very sporty and play competitive sport so that’s great for restricting smartphone use.

Q: How young is too young to own a mobile phone?

MG: Making a decision on when is the right time depends on each child and their parents. It is about responsible parenting and limiting screen time. There is no scientific evidence about what the right age is to give a phone. I have three screenagers and none of them got a phone before the age of 11 years of age. We live in a very technologically advances society and there is no harm in letting children learn early on how to use an i-Pad or tablet. It stops them becoming technophobes when they grow older. The majority of children know more about it than adults now. Obviously you need to monitor what they are using the phone for. We wouldn’t want our children using gambling apps for instance but they mostly just want to keep in touch with their friends. However, parents know their children better than anyone else and there is a reason to give a child a phone when it concerns safety and knowing where your child is, especially if they are walking to and from school. One reason to give a child a phone at the start of secondary school is so that they don’t feel ostracized when they realise everyone else in their class has one. Ironically the majority of kids that have a phone rarely use it to make calls but knowing where they are and being able to talk to them almost instantly is a huge relief for parents.

Q: Anything else you’d like to add?

MG: There’s no scientific evidence that moderate tech use has a negative impact (psychologically or physically on people’s lives). The old cliché is true – everything in moderation. Excessive use of almost anything even when it’s something socially approved and socially sanctioned (e.g., work, exercise, education, etc.) can be problematic if it’s done to the neglect of everything else.

Eight days a week: Survival in the age of the ‘always on’ culture

Recently, I did some work with a PR agency as part of a campaign to get individuals to use their smartphones more responsibly. Today’s blog comprises the some of the text that fed into their press release based on an interview I did with them. The same campaign also publicised my tips to help reduce reliance on technology which you can find here. The following text comes from a transcription of the interview.

“The first thing to bear in mind is that people are no more addicted to smartphones than alcoholics are addicted to bottles. It the applications on smartphones that are potentially addictive not the phones themselves. It is important to understand too that the number of people who actually suffer to the extent that they have a real addiction is likely to be no more than a handful. However, there are certainly a growing number of people who perhaps wish they didn’t use their apps as much as they do. Obviously as phones have become more advanced and more capable, and the issue of both habitual use and problematic use of smartphones has grown.

We live in the ‘always on’ era and I think many people feel obliged to participate in that culture, and ensure that they are constantly available to interact and respond 24/7. I gave up my smart phone several years ago and, though I am not encouraging everybody else to do the same, you will find that after you get over the initial ‘shock’, you are able to cope just fine without it. Usually after the third or fourth day you’ll find that that you have adjusted to not having it. There are natural circumstances where you will find yourself without your phone by necessity, such as when you go swimming or visit the gym. People tend to manage just fine during these scenarios, but many people often experience anxiety if they find themselves on the bus to work and then realise they’ve left their smartphone at home.

unknown

I’d encourage people wishing to use their phone or apps less to consider going without their phone for a few hours, or allocating one day each week when you don’t use it at all. And whilst I have given up my smartphone, I haven’t given up social media, using the internet and sending emails. I simply access these functions through my laptop. Obviously one of the big factors with mobile phones is that they are with you constantly. You can’t put a laptop in a pocket or a handbag, like you can with a mobile phone, and that is obviously quite a significant distinction. 

Many apps and phones themselves now have features that record the amount of time spent using each one, and often the time for many people will escalate into a number of hours over the course of the day or week. For many people this won’t be a concern, because they may be really enjoying using particular apps, but to others it might be a bit of a wake-up call. If you discover that you regularly spend ten hours in a week using a specific app you may begin to consider what else you could have done with that time.

There are also features on phones that allow you to dictate the frequency of notifications you receive as well as limit setting features so that you can control how much time you want to spend on your smartphone. Many apps send notifications very frequently, on the basis that the users will anticipate something good in the message they receive. Like in many spheres of our life, there are specific activities that trigger chemical reactions that manifest themselves as happy feelings, and apps are no different in this respect.

But there are often options to disable these notifications, or to limit them to appear only once an hour. This is one way we can limit the time we spend looking at our phones. The world of social media in particular can be very competitive, and we often crave things like ‘likes’ from our friends and colleagues. Many individuals not only feel good when they get ‘likes’ on the things they have posted on social media but also feel good when they get more ‘likes’ than their friends.

FOMO’ – fear of missing out – is also an increasing factor in why people spend so much time on their smartphone, constantly checking their social media and messages. Individuals should rationally and objectively consider just what exactly it is that they think they’re missing out on. We are very eager to take selfies and share them, purely for the purpose of attracting ‘like’s and reactions from others. Are we really missing out by not doing that? Over the past few years there has been increasing use of the term ‘digital detox’. A digital detox refers to the 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”.

Trait expectations: Another look at why addictive personality is a complete myth

In the 30 years that I have been carrying out research into addiction, the one question that I have been asked the most – particularly by those who work in the print and broadcast media – is whether there is such a thing as an ‘addictive personality’? In a previous blog I briefly reviewed the concept of ‘addictive personality’ but since publishing that article, I have published a short paper in the Global Journal of Addiction and Rehabilitation Medicine on addictive personality, and in this blog I review I outline some of the arguments as to why I think addictive personality is a complete myth.

Psychologists such as Dr. Thomas Sadava have gone as far to say that ‘addictive personality’ is theoretically necessary, logically defensible, and empirically supportable. Sadava argued that if ‘addictive personality’ did not exist then every individual would vulnerable to addiction if they lived in comparable environments, and that those who were addicted would differ only from others in the specifics of their addiction (e.g., alcohol, nicotine, cocaine, heroin). However, Sadava neglected genetic/biological predispositions and the structural characteristics of the substance or behaviour itself.

There are many possible reasons why people believe in the concept of ‘addictive personality’ including the facts that: (i) vulnerability is not perfectly correlated to one’s environment, (ii) some addicts are addicted to more than one substance/activity (cross addiction) and engage themselves in more than one addictive behaviour, and (iii) on giving up addiction some addicts become addicted to another (what I and others have referred to as ‘reciprocity’). In all the papers I have ever read concerning ‘addictive personality’, I have never read a good operational definition of what ‘addictive personality’ actually is (beyond the implicit assumption that it refers to a personality trait that helps explain why individuals become addicted to substances and/or behaviours). Dr. Craig Nakken in his book The Addictive Personality: Understanding the Addictive Process and Compulsive Behaviour argued that ‘addictive personality’ is “created from the illness of addiction”, and that ‘addictive personality’ is a consequence of addiction and not a predisposing factor. In essence, Nakken simply argued that ‘addictive personality’ refers to the personality of an individual once they are addicted, and as such, this has little utility in understanding how and why individuals become addicted.

When teaching my own students about the concept of ‘addictive personality’ I always tell them that operational definitions of constructs in the addictive behaviours field are critical. Given that I have never seen an explicit definition of ‘addictive personality’ I provide my own definition and argue that ‘addictive personality’ (if it exists) is a cognitive and behavioural style which is both specific and personal that renders an individual vulnerable to acquiring and maintaining one or more addictive behaviours at any one time. I also agree with addiction experts that the relationship between addictive characteristics and personality variables depend on the theoretical considerations of personality. According to Dr. Peter Nathan there must be ‘standards of proof’ to show valid associations between personality and addictive behaviour. He reported that for the personality trait or factor to genuinely exist it must: (i) either precede the initial signs of the disorder or must be a direct and lasting feature of the disorder, (ii) be specific to the disorder rather than antecedent, coincident or consequent to other disorders/behaviours that often accompany addictive behaviour, (iii) be discriminative, and (iv) be related to the addictive behaviour on the basis of independently confirmed empirical, rather than clinical, evidence. As far as I am aware, there is no study that has ever met these four standards of proof, and consequently I would argue on the basis of these that there is no ‘addictive personality’.

Although I do not believe in the concept of ‘addictive personality’ this does not mean that personality factors are not important in the acquisition, development, and maintenance of addictive behaviours. They clearly are. For instance, a paper in the Psychological Bulletin by Dr. Roman Kotov and his colleagues examined the associations between substance use disorders (SUDs) and higher order personality traits (i.e., the ‘big five’ of openness to experience, conscientiousness, agreeableness, extraversion, and neuroticism) in 66 meta-analyses. Their review included 175 studies (with sample sizes ranged from 1,076 to 75,229) and findings demonstrated that SUD addicts were high on neuroticism (and was the strongest personality trait associated with SUD addiction) and low on conscientiousness. Many of the studies the reviewed also reported that agreeableness and openness were largely unrelated to SUDs.

Dr. John Malouff and colleagues carried published a meta-analysis in the Journal of Drug Education examining the relationship between the five-factor model of personality and alcohol. The meta-analysis included 20 studies (n=7,886) and showed alcohol involvement was associated with low conscientiousness, low agreeableness, and high neuroticism. Mixed-sex samples tended to have lower effect sizes than single-sex samples, suggesting that mixing sexes in data analysis may obscure the effects of personality. Dr. James Hittner and Dr. Rhonda Swickert published a meta-analysis in the journal Addictive Behaviors examining the association between sensation seeking and alcohol use. An analysis of 61 studies revealed a small to moderate size heterogeneous effect between alcohol use and total scores on the sensation seeking scale. Further analysis of the sensation seeking components indicated that disinhibition was most strongly correlated with alcohol use.

Dr. Marcus Munafo and colleagues published a meta-analysis in the journal Nicotine and Tobacco Research examining strength and direction of the association between smoking status and personality. They included 25 cross-sectional studies that reported personality data for adult smokers and non-smokers and reported a significant difference between smokers and non-smokers on both extraversion and neuroticism traits. In relation to gambling disorder, Dr. Vance MacLaren and colleagues published a meta-analysis of 44 studies that had examined the personality traits of pathological gamblers (N=2,134) and non-pathological gambling control groups (N=5,321) in the journal Clinical Psychology Review. Gambling addiction was shown to be associated with urgency, premeditation, perseverance, and sensation seeking aspects of impulsivity. They concluded that individual personality characteristics may be important in the aetiology of pathological gambling and that the findings were similar to the meta-analysis of substance use disorders by Kotov and colleagues.

More recently, I co-authored a study with Dr. Cecilie Andreassen and her colleagues in the Journal of Behavioral Addictions. We carried out the first ever study investigating the inter-relationships between the ‘big five’ personality traits and behavioural addictions. They assessed seven behavioural addictions (i.e., Facebook addiction, video game addiction, Internet addiction, exercise addiction, mobile phone addiction, compulsive buying, and study addiction). Of 21 inter-correlations between the seven behavioural addictions, all were positive (and nine significantly so). More specifically: (i) neuroticism was positively associated with Internet addiction, exercise addiction, compulsive buying, and study addiction, (ii) extroversion was positively associated with Facebook addiction, exercise addiction, mobile phone addiction, and compulsive buying, (iii) openness was negatively associated with Facebook addiction and mobile phone addiction, (iv) agreeableness was negatively associated with Internet addiction, exercise addiction, mobile phone addiction, and compulsive buying, and (v) conscientiousness was negatively associated with Facebook addiction, video game addiction, Internet addiction, and compulsive buying and positively associated with exercise addiction and study addiction. However, replication and extension of these findings is needed before any definitive conclusions can be made.

Overall these studies examining personality and addiction consistently demonstrate that addictive behaviours are correlated with high levels of neuroticism and low levels of conscientiousness. However, there is no evidence of a single trait (or set of traits) that is predictive of addiction, and addiction alone. Others have also reached the same conclusion based on the available evidence. For instance, R.G. Pols (in Australian Drug/Alcohol Review) noted that findings from prospective studies are inconsistent with retrospective and cross-sectional studies leading to the conclusion that the ‘addictive personality’ is a myth. Dr. John Kerr in the journal Human Psychopharmacology: Clinical and Experimental noted that ‘addictive personality’ had long been argued as a viable construct (particularly in the USA) but that there is simply no evidence for the existence of a personality type that is prone to addiction. In another review of drug addictions, Kevin Conway and colleagues asserted (in the journal Drug and Alcohol Dependence) there was scant evidence that personality traits were associated with psychoactive substance choice. Most recently, Maia Szalavitz in her book Unbroken Brain: A Revolutionary New Way of Understanding Addiction noted that:

“Fundamentally, the idea of a general addictive personality is a myth. Research finds no universal character traits that are common to all addicted people. Only half have more than one addiction (not including cigarettes)—and many can control their engagement with some addictive substances or activities, but not others”.

Clearly there are common findings across a number of differing addictions (such as similarities in personality profiles using the ‘big five’ traits) but it is hard to establish whether these traits are antecedent to the addiction or caused by it. Within most addictions there appear to be more than one sub-type of addict suggesting different pathways of how and way individuals might develop various addictions. If this is the case – and I believe that it is – where does that leave the ‘addictive personality’ construct?

‘Addictive personality’ is arguably a ‘one type fits all’ approach and there is now much evidence that the causes of addiction are biopsychosocial from an individual perspective, and that situational determinants (e.g., accessibility to the drug/behaviour, advertising and marketing, etc.) and structural determinants (e.g., toxicity of a specific drug, game speed in gambling, etc.) can also be influential in the aetiology of problematic and addictive behaviours. Another problem with ‘addictive personality’ being an explanation for why individuals develop addictions is that the concept inherently absolves an individual’s responsibility of developing an addiction and puts the onus on others in treating the addiction. Ultimately, all addicts have to take some responsibility in the development of their problematic behaviour and they have to take some ownership for overcoming their addiction. Personally, I believe it is better to concentrate research into risk and protective factors of addiction rather than further research of ‘addictive personality’.

As I have argued in a number of my papers and book chapters, not every addict has a personality disorder, and not every person with a personality disorder has an addiction. While some personality disorders appear to have an association with addiction including Antisocial Personality Disorder and Borderline Personality Disorder, just because a person has some of the personality traits associated with addiction does not mean they are, or will become, an addict. Practitioners consider specific personality traits to be warning signs, but that’s all they are. There is no personality trait that guarantees an individual will develop an addiction and there is little evidence for an ‘addictive personality’ that is predictive of addiction alone. In short, ‘addictive personality’ is a complete myth.

If phonely: Are you addicted to your mobile phone?

A couple of weeks ago I was interviewed by Debating Europe (DE) about smartphone addiction. I was asked four questions and my responses were transcribed, edited, and published on the DE website on July 11. Only the responses to two of the questions were published, so my blog today provides the full transcript of my interview. I have emboldened each of the four questions and my response follows each question.

Vicki worries about the impact of smartphones on children. She thinks that parents nowadays are too prone to buying the latest phones for their kids, without taking into consideration possible alternatives. What are the risks of children being addicted to their phones?

Well, first thing to say is that children and adults are no more addicted to their smartphones than alcoholics are addicted to a bottle. What we’re really talking about here is the application that people have on smartphones. Obviously, children now seem to getting smartphones at a younger and younger age. I’m often asked what is an appropriate age to give children smartphones. There is no right answer on this, but I certainly don’t advocate giving smartphones to children under the age of 11 years.

I think when children move to their secondary schools, most children in the class will have a smartphone, and to not give your child a smartphone can ostracise them from the class. The issue about smartphones in terms of excessive use is that sometimes parents do actually pathologise their children’s excessive smartphone use, particularly if they don’t use a smartphone much themselves. For me, the issue is whether their smartphone use interferes with the other important things in their lives?

There are typically four things I ask parents: One, is smartphone use affecting your child’s education and homework? Two, is their smartphone use affecting their physical education? Three. is their smartphone use affecting the chores you expect your children to do around the house? And, finally, does the smartphone use affect their face-to-face interaction with their friends? Typically, most parents, if they’ve answered honestly, will answer that the smartphone doesn’t affect any of those four domains. But if a parent does feel it’s affecting those four domains, then it is the parent’s responsibility to do something about it.

As a parent myself, I know that taking a smartphone off a child can be very difficult sometimes and can lead to negative reactions by the child. But at the end of the day, a parent is there to parent. They’re there to oversee their child’s development into – hopefully – a thriving adult who’s got all the capacities to go on in the world. Using smartphones, unfortunately or fortunately – depending upon your viewpoint – is now a natural thing and, particularly in teenage years, that is what children do. So I think it comes down to everything in moderation and parents absolutely have the right to restrict screen time and in extreme circumstances actually take the smartphones away.

Stella thinks we’re being too negative about mobile phones. She thinks technology such as smartphones actually increases the sense of community and allows for expression of opinions. What would you say to her? Is she right to be so optimistic or should it be tempered?

It’s all about moderation. I personally think the advantages of smartphones far outweigh the disadvantages. I’m actually an unusual person. I actually gave using up my mobile phone a number of years ago, and I’ve now learned to live without one. But – to be honest – particularly for most teenagers, this is absolutely essential in their day-to-day social armoury. I don’t think there’s any argument that there should be a ban or a prohibition on smartphones because, as I said, the advantages far outweigh the disadvantages.

The scientific research says that a very small minority seem to overuse their smartphones, particularly young people aged between 14-to-25 years. We’ve got teenagers, older adolescents and emerging adults who heavily use their smartphones. I think most of that use is what I call ‘habitual use’. It’s not ‘problematic use’, it’s just something that people get into a habit of doing, always looking at their mobile phones even when there hasn’t been a ‘ping’ or a beep to say there’s been a notification or a message. People still automatically look at their smartphone even if there’s no sound. It’s almost like a classically conditioned response.

I think more people pathologise use. For most people, their smartphone use is not pathological in any way, shape, or form. It’s just that, sometimes, excessive use is pathologised by people who don’t like mobile phones. I notice mobile phones when I’m in a restaurant or a pub, because I don’t have one myself. I’m actually very conscious when somebody else is looking at their mobile phone during mid-conversation, and that has led to this phrase ‘phubbing’, which is ‘phone snubbing’ and which goes on all the time. But that, in and of itself, is not an addiction and is not excessive.

I certainly think that in terms of the question asked, I do think there’s a lot of good things to say about mobile phones and I wouldn’t want to be in a position where they’re not around because for some people they’re life-savers and for some it’s part of their social armoury. I do think that the way social media operators use their psychological hooks to get people to look at their phones is something where the onus is on the social media operators rather than the individuals.    

Reader ‘Randomguy2017’ is sceptical of the benefits of technological progress. He argues that depression and anxiety are higher than ever, as our addiction to smartphones grow. Is there a link between the two?

As far as I’m aware – and I may be wrong – there is no scientific longitudinal study that has looked at the relationship between smartphone use, depression and anxiety. I certainly think it’s a case where it’s a bit of a ‘chicken and egg’ thing. If you’re somebody that’s prone to anxiety or depression, you’re more likely to use smartphones or the Internet as a way masking depression and anxiety. There’s also some research that suggests excessive use of smartphones and the Internet can lead to social anxiety and depression. So, like I said before, there’s a bit of ‘chicken and the egg’ here. It may be also be that there is a bit of both.

Again, I would really stress that the number of people that would be genuinely addicted to applications on their smartphone are very few and far between. I think what we’ve got more now is that the excessive smartphone use sometimes leads to problematic behaviour. It could be that you’re looking at your smartphone while you’re driving, or you prefer to look at your smartphone rather than talk to somebody in front of you face-to-face. Those kind of things, they are what I would say are ‘problematic’ and annoying and, in the case of driving, could actually be fatal, but none of those are necessarily addictive or pathological.

However, I do think we have to put these things into perspective. The vast majority of people that use smartphone-based technologies, it’s something that’s life-affirming, life-enhancing, that adds to their life. But that doesn’t take away the fact that small minority out there that their use of smartphones takes away from other important things in their life. And in a tiny minority of cases the application that people are engaging in online whether its social networking, gaming, or gambling might be potentially addictive. But I take a holistic approach in this, in that the advantages far outweigh the disadvantages.

Emil is concerned about the privacy implications of our reliance on phones. Is he correct in assuming hackers can easily access what we do on our phones?

This is not my research area as I don’t look at privacy issues in relation to Internet and smartphone use. However, I’ve got access to people’s data from gambling companies and we do research on that data. I think that people have got to realise that anything they do online, when you’ve signed up to do anything, whether it’s a gambling service, a gaming service, a social networking site, is that you are – in effect – giving your data away.

When my kids come to me and say to me, ‘Can I do this, it’s free?’ I have to educate my children when anything is free, via smartphone or the Internet, then you yourself are the product that’s actually being sold. It’s very hard to educate a 12 or 13-year-old about that, but I think you can say to adults that their data is being used and sold in ways that they never imagined.

But I do think that this ‘big data’ revolution that we’ve got now can result in very good potential uses of that data, particularly at an aggregate level. But I certainly know that on an individual level, I don’t like my own data being used. If I sign up and buy things from Amazon, I know they’re going to use my data. If I sign up to use Facebook, I know my data is being used some way. So it’s a bit of give and take. In Europe, we’ve just had new regulation regarding data privacy. Obviously governments are trying to get on top of this, but we now live in a digital world, we leave digital footprints, and our data is going to be used in ways we never thought it might be used in the first place. That is the trade-off between having all these advantages of new technologies versus those privacy issues.

Story rebellion: A brief look at ‘news addiction’

Earlier this year, I was contacted by a BBC reporter asking me what the latest research on ‘news addiction’ was. I politely told him I was unaware of any such research and that if ‘news addiction’ existed, it would be more akin to ‘television addiction’ or ‘boxset bingeing’. About a month after that call, a paper on ‘news addiction’ was published in the Journal of the Dow University of Health Sciences Karachi by Pakistani psychologists Ghulam Ishaq, Rafia Rafique, and Muhammad Asif.

I have to admit that some might say I’m a bit of a ‘news junkie’. As soon as I get up in the morning or as soon as I come home from work I switch on the radio or television to listen to the news. However, I do not consider my love of listening to the news to be an addiction, and I suspect most people like me wouldn’t either. Of course, there are now other ways for individuals to get their ‘news fix’ including thousands of online news sites and via social media which is why Ishaq and his colleagues decided to look at the construct of ‘news addiction’. They claimed that:

“People are persuaded towards news. Similarly, engrossment of certain individuals in any domain from politics, sports, global issues, arson or terrorism can also promote news habituation or addiction and intensify inspection towards news. News addiction comes under the term behavioral-related behavior…When somebody interacts with news, this gives him/her satisfying feelings and sensations that he/she is not able to get in other ways. The reinforcement an individual gets from these feelings compels him to repeat their behavior to get these types of feelings and sensations repeatedly… eventually causing a disturbance in every sphere of life… individuals who are addicted to news feel themselves much obsessed to check the news in uncontrollable ways”.

Screen Shot 2017-12-04 at 16.42.08Theoretically there is no reason why individuals cannot be addicted to reading and/or listening to the news as long as they are being constantly rewarded for their behaviour. In fact, the authors used some of my papers on behavioural addiction more generally to argue for the construct of ‘news addiction’ as a construct to be empirically investigated. In their study, Ishaq and colleagues wanted to examine the relationship between (the personality construct of) conscientiousness, neuroticism, self-control, and news addiction. Conscientiousness is a personality trait and refers to individuals who are orderly, careful, and well organised. Neuroticism is another major personality trait and refers to individuals who have high mental instability such as depression and high anxiety. The researchers hypothesised that there would be negative correlation between conscientiousness and news addiction, and that neuroticism would be positively correlated with news addiction.

To test their hypotheses, a survey was completed by 300 participants (aged 18 to 60 years; average age 39 years) from major cities of the Punjab (Lahore, Multan, Bahawalpur, Faisalabad, Sargodha). The authors developed their own 19-item News Addiction Scale (NAS) although the paper didn’t give any examples of any of the items in the NAS. They also administered the ‘Big Five Inventory’ (which assesses five major personality traits – Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism). The study found that the hypotheses were supported (i.e., news addiction was positively correlated with neuroticism and negatively correlated with conscientiousness. Previous literature has consistently shown that there is relationship between personality traits and behavioural addiction. The findings of this study are very similar to those more widely in the general literature for both substance and behavioural addictions (which also show most addictions have a low correlation with conscientiousness and a high correlation with neuroticism). The authors also argued that:

“(The findings show that) self-control plays an active role [in] refraining from the instant pleasure of impulse that would hinder with daily functioning and attainment goals…[The] current study findings demonstrated that self-control acts as a mediating variable between conscientiousness, neuroticism and news addiction”.

They also reported that females had higher scores on neuroticism and conscientiousness and that males had higher scores on the News Addiction Scale. The authors also claimed that there was much similarity between social media addiction (although provided no evidence for this except to say that they were both examples of behavioural addiction).

There was no mention at all in the paper about how their participants accessed their news. I access most (but certainly not all) of my news via television and therefore if I was watching an abnormal amount of news on the television, this would more likely be a sub-type of television addiction or a sub-type of television binge-watcher (both of which have been reported in the psychological literature). If someone addictively accessed all their news online or via social media, this could perhaps come under more general umbrella terms such as ‘internet addiction’ or ‘social media addiction’.

However, things are further complicated by the fact that ‘news’ can be defined in a number of ways. In the study by Ishaq and colleagues, news was defined as a statement of specific information and facts and figures on any substantial event” but such a definition doesn’t take into account such things as political opinions and nor does it define what a ‘substantial event’ is. Given that this is the only study on news addiction that I am aware of, I’ll need a lot more research evidence before I am convinced that it really exists.

The junkie generation? Teenage “addiction” to social media

Earlier today I appeared live on my local radio station (BBC Radio Nottingham) commenting on a study released by the Allen Carr Addiction Clinics (ACAC) concerning teenage addiction (and more specifically addiction to social media). The study was a survey of 1,000 British teenagers aged 12 to 18 years old and the press release went with the heading “INFO UK BREEDING A GENERATION OF TEENAGE ADDICTS SAYS NEW STUDY” (their capital letters, not mine) with the sub-headline that “83% of UK teenagers would struggle to go ‘cold turkey’ from social media and their other vices for a month”.

As someone that has spent almost 30 years studying ‘technological addictions’ I was interested in the survey’s findings. I tried to get hold of the actual report by contacting the ACAC Press Office. They were very helpful and sent me a copy of the Excel file containing the raw data (entitled ‘Addicted Britain’). They also informed me that the data were collected for ACAC by the market research company OnePoll, and that the teenagers filled out the survey online (with parents’ permission). However, there is no actual published report with the findings (and more importantly, no methodological details). I asked ACAC if they knew the response rate (for instance, was the online survey sent to 10,000 teenagers to get their 1,000 responses that would give a response rate of 10%), and how were the teenagers recruited in the first place. Also, as the survey was carried out online, those teenagers who are the most tech-savvy and feel confident online, would be more likely to participate than those who don’t like (or rarely use) online applications. Before I comment on the survey itself, I would just like to provide some excerpts from the press release that was sent out:

“The explosion of social media, selfies and mobile devices is priming a generation of UK teenagers for a lifelong struggle with addiction…83% of UK teenagers admit they would struggle to give up their vices for a whole month. [The study] unveiled a worrying trend of growing numbers of young people constantly striving to find the next thrill, mostly via technology and social media. When asked which behaviours they could abstain from, UK teens said they would most struggle living without texting (66%), followed by social networking (58%), junk food (28%) and alcohol (6%). The report found that the average teen checks social media 11 times a days, sends 17 text messages and takes a ‘selfie’ picture every four days. This constant pursuit of stimulation, peer approval, instant gratification, and elements of narcissism are all potential indicators of addictive behaviour. The study highlights that parents across the UK are inadvertently becoming ‘co-dependents’ enabling their child’s addictions by providing them with cash albeit with the best of intentions”.

The first thing that struck me reading this text was the use of the word “vice”. Most dictionary definitions of a vice is “immoral or wicked behaviour” or criminal activities involving prostitution, pornography, or drugs”. As far as I am concerned, social networking, junk food, and alcohol are not vices (especially social networking). The whole wording of the press release is written in a way to pathologise normal behaviours such as engaging in social media use. Also, asking teenagers about which behaviours they could not abstain from for a month tells us almost nothing about addiction. All it tells us is that the activities that teenagers most engage in are the ones they would find hardest not to do. This is just common sense. My main hobbies are listening to music on my i-Pod and reading. I would really have difficulty in not listening to my favourite music or reading for a whole month but I’m not addicted to music or reading.

The ACAC kindly sent me all the questions that were asked in the survey and there was no kind of addiction scale embedded in any of the questions asked. Basically, the survey does not investigate teenagers’ potential addictions, as no screening instrument for any behaviour asked about was included in the survey. There were some attitude questions asking whether activities like social networking could be addictive, but as I have argued in previous blogs, almost any activity that is constantly rewarding can be potentially addictive.

That’s not so say we shouldn’t be concerned about teenagers’ excessive use of technology as my own research has shown that a small minority of teenagers do appear to have problems and/or be addicted to various online activities. However, as my research has shown, doing something excessively doesn’t mean that it is addictive. As I have noted in a number of my academic papers, the difference between a healthy enthusiasm and an addiction is that healthy enthusiasm add to life and addictions take away from it. The perceived overuse of technology by the vast majority of teenagers is quite clearly something that is life-enhancing and positive with no detrimental effects whatsover.

Given that the vast majority of teenagers use the social media to communicate and interact with friends, I was surprised that ACAC’s findings were not closer to 100% saying that they couldn’t abstain for one month. Which teenagers would find it easy not to use social media for a month given how important it is in their day-to-day social lives? The findings in the press release also quote John Dicey (Global Managing Director and Senior Therapist of ACAC) who said:

“The findings of this report are cause for concern and highlight a generation of young people exhibiting many of the hallmarks of addictive behaviour. The explosion of technology we have seen since the late 90’s offers incredible opportunities to our youth – the constant stimulation provided by access to the internet for example can be a good or a bad thing. There’s a price to pay. This study indicates that huge numbers of young people are developing compulsions and behaviours that they’re not entirely in control of and cannot financially support. Unless we educate our young people as to the dangers of constant stimulation and consumption, we are sleepwalking towards an epidemic of adulthood addiction in the future”.

While my own research shows that a small minority of teenagers experience problems concerning various online activities, there was almost nothing in the ACAC report “huge numbers of young people are developing compulsions and behaviours that they’re not entirely in control of”. The use of the word “huge” is what we psychologists call a ‘fuzzy quantifier’ (as what is ‘huge’ to one person may not be ‘huge’ to another). Mr. Dicey’s conclusions simply cannot be made from the data collected. He says that the report shows that many teenagers are displaying the “hallmarks of addictive behaviour” but given no addiction screening instruments were used, the data do not show this. The press release uses the following findings to make the claim that “the abundance of technology that UK teens can access seems to be creating a generation of ‘tech addicts’!”

“One-third of UK teens (32%) admit they check social media more than 10 times a day. The report also found that the average teen checks social media 11 times day, which equals once every 1.5 hours they are awake. UK teens are also avid takers of ‘selfies’, with over a quarter taking more than 10 a month. The average teen takes 7.4 selfies a month, equalling one every four days on average…The plethora of technology available to teens is also having a worrying impact on their attention spans. 1 in 4 teens have over 20 apps on their smartphones, with the average teen having 13 apps on their device. The constant search for the ‘next thing’ is evidenced in how they use apps – 46% admitted that they stop using or delete an app less than a week after using it, freeing up storage space for a new app”.

Anyone that has teenagers (I have three screenagers myself) will tell you that the above statistics indicate adolescent normality not addiction. Checking social media 10 times a day does not indicate addiction in the slightest. Although I have never taken a selfie, I check my social media far more than 10 times a day. Deleting apps to make way for other apps is no different from me removing songs on my i-Pod every week to make way for other songs I want to listen to. Again, there is absolutely nothing in these statistics that provides evidence of adolescent addiction.

Anyone that is aware of my work will know that I take the issue of teenage technology use seriously and that I firmly believe that a small minority of adolescents experience addiction to various online applications. However, studies like the one done for ACAC do little for the area as the rhetoric of the claims are unsupported by their data.
