Out of sports: The influence of structural and situational characteristics in online sports betting

In a paper that I recently co-wrote in the Journal of Sport and Social Issues with Hibai Lopez-Gonzalez and Ana Estevez, we argued that the growing conversion of sports betting into an online activity has prompted two types of transformations in the way companies market their betting products. Firstly, the Internet has not only extended the opportunities to bet but has also changed the characteristics of the betting practice itself. Such product characteristics can be divided into two categories, namely situational and structural characteristics, that appear to be associated with factors influencing the onset and maintaining of betting as well as the difficulty of discontinuing it (the focus of this blog). Secondly, the online dimension has also enabled the proliferation of cross-marketing strategies leading to a convergence between previously independent markets or the tightening of the relationship between those with already established synergies (which I will examine in a future blog).

The internet has substantially transformed the situational and structural characteristics of sports betting. Situational factors comprise all environmental features that might make gamblers feel comfortable (both psychologically and physically) while gambling including sensory factors like colour, music, and smell in the environment, novelty of the activity, accessibility or proximity to a gambling venue, social facilitation and intrinsic association, which is defined as ‘the degree to which gambling is associated with other interests and attractions’.

New situational factors in online sports betting include: (i) easier and faster accessibility to betting opportunities; (ii) ubiquity of bettable competitions around the globe and seamless availability of those competitions around the clock; (iii) anonymity (in terms of social stigma traditionally attached to gambling) and comfortable betting from home or elsewhere via mobile devices; (iv) greater social facilitation via online communities of bettors or betting leagues organized between groups of friends; and (v) an enhanced intrinsic association of sports betting with sporting values such as health, competition, team identification and loyalty, further facilitated by the proliferation of live sport content on television and social media.

Structural factors refer to the specific characteristics or design of the gambling activity such as win probability, sound and lighting effects of the game, bet frequency (how many bets a person can place in a given period of time), loss chasing facilitation (gambling to recover lost money), jackpot size, price structure, near-miss opportunities (the psychological bias of interpreting losses as nearly wins or anticipatory of a winning streak).

New structural factors in online betting include: (i) a greater frequency of bets, with shorter intervals between bets, and shorter event durations (e.g., virtual sports), meaning faster reward mechanisms; (ii) in-play betting, which encompasses a closer connection between watching sport and betting; (iii) contextual betting, with live markets that open after specific actions (e.g. betting on the outcome of a penalty kick seconds after being awarded by the referee); (iv) greater illusion of control over the bets with new functionalities that emphasize the skills involved and diminish the role of luck, such as cash out (the person can withdraw the bet before the end of the event at the price stipulated by the betting site), accumulators (a person can aggregate multiple events in a single bet, increasing the potential return), exchange (betting against other people instead of the bookmaker); and (v) a greater integration in the betting process of the knowledge about the sport (e.g., daily fantasy sports), resulting in the gamification of the betting experience.

In a 2013 scoping study that I published with Dr. Abby McCormack in the International Journal of Cyber Behavior, Psychology and Learning, we noted that new situational and structural factors associated with Internet gambling could influence the onset of problem gambling in non-sporting gambling contexts. The relative novelty of these situational and structural characteristics affecting the wagering on sports is reflected in the scarcity of research devoted to understanding them. However, there are a few studies.

An analysis of 47,603 Bwin betting website subscribers (by Dr. Debi LaPLante and colleagues in the journal Computers in Human Behaviors) showed some interesting results in the direction of the importance of structural factors determining excessive gambling. The most involved bettors (those comprising the most active 1% of the user sample) who gambled on final outcomes did not escalate their gambling behaviour over time whereas those who gambled in-play did so. In a 2014 follow-up study in the journal Psychology of Addictive Behaviors, LaPlante and her colleagues examined the effect of in-play betting in the development of problem gambling. The researchers expanded the sample to other forms of gambling and compared the role of breadth (i.e., many different gambling forms) and depth involvement (i.e., more frequent betting) in problem gambling onset. They hypothesised that more involved users would be more likely to become problem gamblers (which was shown to be the case). For every form and gambling, when controlling for depth and breadth involvement, the model was not able to predict gambling-related problems, with one exception: in-play betting. The study suggested that a structural characteristic of a game, the live betting action, could be a precipitant, in conjunction with other determinants, of gambling disorders.

Another study by Dr. Richard LaBrie and Dr. Howard Shaffer (in a 2011 issue of Addiction Research and Theory) found that self-limiting features – in which the bettor determines a maximum amount of money to be bet – made problem gamblers bet less frequently but, in turn, increased the stakes of the bets placed. Bettors who scored high on problem gambling scales chased their losses by implementing a risk aversion strategy, placing high bets conservatively on short odds events (i.e., events with unbalanced contenders in which the outcome can more likely be determined beforehand but with a lower monetary return).

While there has been an increasing amount of research that has examined the influence of situational and structural characteristics in gambling (particularly in relation to slot machine gambling), the impact of such characteristics on online sports betting (at present) remains largely unknown.

Ad-ding to the gambling literature: A brief overview of our recent papers on sports gambling advertising

Over the last 18 months I have been working with Dr. Hibai Lopez-Gonzalez on a project examining online sports betting and online sports betting advertising. We have already had eight papers accepted for publication and today’s blog briefly rounds up the ones that specifically relate to online sports betting. If you would like copies of them, please click on the hyperlinks. If you are unable to access them, then drop me an email and I will send you a copy (mark.griffiths@ntu.ac.uk).

  • In this article, online sports betting is explored with the objective of critically examining the potential impact on problem gambling of the emerging product features and advertising techniques used to market it. First, the extent of the issue is assessed by reviewing the sports betting prevalence rates and its association with gambling disorders, acknowledging the methodological difficulties of an unambiguous identification of what exactly constitutes sports-related gambling today. Second, the main changes in the marketization of online betting products are outlined, with specific focus on the new situational and structural characteristics that such products present along with the convergence of online betting with other adjacent products. Third, some of the most prevalent advertising master narratives employed by the betting industry are introduced, and the implications for problem gamblers and minors are discussed.

  • Gambling disorder is known to have a negatively detrimental impact on affected individual’s physical and psychological health, social relationships, and finances. Via remote technologies (e.g., Internet, mobile phones, and interactive television), gambling has come out of gambling venues and has brought the potential for online gambling to occur anywhere (e.g., the home, the workplace, and on the move). Alongside the rise of online gambling, online gambling advertising have spread throughout all type of media. In a sample of 201 Spanish university students, the present study explored the perceived influence of online gambling advertising. More specifically it examined the Third-Person Effect (TPE), and its consequences on individuals’ willingness to support censorship or public service advertising. The findings demonstrate that despite the difference on the perception of the effects of online gambling advertising, it scarcely accounts for the behavioural outcomes analysed. On the contrary, awareness of problem gambling and, above all, paternalistic attitudes appear to explain this support

  • Environmental stimuli in the form of marketing inducements to gamble money on sports have increased in recent years. The purpose of the present paper is to tackle the extended definition of the gamblification of sport using sponsorship and partnership deals of gambling, forex trading, and fantasy gaming as a proxy for assessing its environmental impact. Using data concerning sponsorship deals from English Football Premier League, the paper builds on the evidence of English football’s gamblification process to discuss the impact that the volume, penetration, and marketing strategies of sports betting might have on public health and wellbeing. Findings demonstrate that gambling marketing has become firmly embedded in the financial practices of many English Premiership football clubs. It is argued that such associations are not trivial, and that the symbolic linkage of sport and newer gambling forms may become an issue of public health, especially affecting vulnerable groups such as minors and problem gamblers. The present study is the first to explore in-depth the relationship and potential consequences and psychosocial impacts of sports-related marketing, particularly in relation to football.

Lopez-Gonzalez, H., Guerrero-Sole, F. & Griffiths, M.D. (2017). A content analysis of how ‘normal’ sports betting behaviour is represented in gambling advertising. Addiction Research and Theory, in press.

  • Previous research has suggested that motives play an important role in several potentially addictive activities including online gaming. The aims of the present study were to (i) examine the mediation effect of different online gaming motives between psychiatric distress and problematic online gaming, and (ii) validate Italian versions of the Problematic Online Gaming Questionnaire, and the Motives for Online Gaming Questionnaire. Data collection took place online and targeted Italian-speaking online gamers active on popular Italian gaming forums, and/or Italian groups related to online games on social networking sites. The final sample size comprised 327 participants (mean age 23.1 years [SD=7.0], 83.7% male). The two instruments showed good psychometric properties in the Italian sample. General psychiatric distress had both a significant direct effect on problematic online gaming and a significant indirect effect via two motives: escape and fantasy. Psychiatric symptoms are both directly and indirectly associated with problematic online gaming. Playing online games to escape and to avoid everyday problems appears to be a motivation associated with psychiatric distress and in predicting problematic gaming.

  • The prevalence of sports betting advertising has become a major concern for gambling regulators, particularly since the legalization of online gambling in many European jurisdictions. Although the composition of gambling advertisement narratives has received some limited attention, nothing is known regarding how betting advertisements (often referred to as ‘adverts’ or ‘commercials’) might be associating gambling with other potentially risky behaviors. The present paper examines the representation of alcohol drinking and low nutritional value food eating in sports betting advertising. By means of a mixed-methods approach to content analysis, a sample of British and Spanish soccer betting adverts was analyzed (N=135). The results suggest that betting advertising aligns drinking alcohol with sports culture, and significantly associates emotionally-charged sporting situations such as watching live games or celebrating goals with alcohol. Additionally, alcohol drinking is more frequent in betting adverts with a higher number of characters, linking friendship bonding and alcohol drinking (especially beer) in the context of sports gambling.

Lopez-Gonzalez, H., Estévez, A. & Griffiths, M.D. (2017). Controlling the illusion of control: A grounded theory of sports betting advertising in the UK. International Gambling Studies, in press.

  • Sports betting advertising has arguably permeated contemporary sport consumption in many countries. Advertisements build narratives that represent situations and characters that normalize betting behaviour and raise public concerns regarding their detrimental effect on vulnerable groups. Adopting a grounded theory approach, the present study examined a British sample of sports betting advertisements (N = 102) from 2014 to 2016. The analysis revealed that individual themes aligned in a single core narrative, constructing a dual persuasive strategy of sports betting advertising: (i) to reduce the perceived risk involved in betting (with themes such as betting with friends, free money offers, humour, or the use of celebrities) while (ii) enhancing the perceived control of bettors (including themes of masculinity and sport knowledge). In addition, new technological features of sports betting platforms (e.g. live in-play betting) were used by advertisers to build narratives in which the ability to predict a sports outcome was overlapped by the ability of bettors to use such platforms, equalizing the ease of betting with the ease of winning. Based on the data analysed, it was concluded that the construction of a magnified idea of control in sports betting advertising is a cause for concern that requires close regulatory scrutiny.

Learning, yearning, but not earning: A brief look at student gambling

Last week, the UK Gambling Commission put out a press release relating to student gambling. Having been in the university sector for as long as I have been researching gambling (i.e., 30 years), student gambling is an area that has always been close to my professional heart. I have published dozens of papers on youth gambling and student gambling over the last three decades (see ‘Further reading’ below for a few examples).

With my daughter leaving home to go to university this week there are lots I could potentially worry about and gambling isn’t necessarily my main concern where my daughter is concerned, but gambling is still of concern to me especially because a study I published back in 2012 with Luke Benson and Dr. Christine Norman (in the International Journal of Mental Health and Addiction) found that first year university students gambled more than final year students and were more susceptible to problem gambling compared to final year students.

Screen Shot 2017-09-25 at 20.20.25

The Gambling Commission have just published their own research into the topic. They hired Youth Sight who conducted 1,000 online interviews with undergraduate students in August 2017 (the students were part of an online panel recruited from applicants through Universities and Colleges Admission Service). The quotas chosen reflected the UK student population in terms of gender, course year and university group. Here are some of their key findings:

  • Two-thirds of students had gambled in the previous month
  • Over half of student gamblers (54%) engaged in gambling to make money
  • Two-fifths of students said they felt guilty after they had gambled
  • One in eight student gamblers had missed lectures due to gambling
  • One in four student gamblers (25%) had spent more money gambling than they could afford
  • One in 25 student gamblers (4%) were in debt because of their gambling
  • One in four students that had a gambling debt, had a debt of over £10,000

The Gambling Commission noted there were are number of limitations with the study. They specifically noted that gambling participation rates may have been higher than if the data had been collected using other methodologies (telephone, face-to-face interviews) due to the self-selecting nature of online surveys. However, online surveys were chosen due to students’ access to technology and the availability of a representative panel via this method. 

On the back of their survey, the Gambling Commission also provided their top ten tips to help students avoid getting into trouble with gambling. I have reproduced them here verbatim.

  • Ask yourself why you are gambling: Are you gambling to escape debt or as a way to make quick money? Think carefully about your motivations to gamble. Gambling shouldn’t be seen as the answer to improving your personal finances. If you have concerns about money, speak to a financial adviser or student support services.
  • Monitor how often you’re gambling online: Websites must give you access to historic account activity. This means you can see exactly when, how much and what you’ve been gambling on over time and make well-informed choices about what to do next.
  • Keep track of how much time you’ve spent gambling: With a reality check, you can set alerts to pop up on screen, which help you to monitor the time spent gambling either online or on gaming machines in a betting shop.
  • Limit how much you can spend: If you’re concerned about how much money you’re gambling, you can set a limit on how much you spend across individual gambling products online. You can also set a limit on how much you spend on gaming machines in a betting shop.
  • Give yourself a timeout: During a timeout, you can block yourself from gambling online for a set amount of time, of up to 6 weeks, and even bar yourself from gambling during a specific time of day.
  • Need a longer break? Self-exclude from gambling firms for a minimum of 6 months: If you think you are spending too much time or money gambling – whether online or in gambling premises – you can ask to be self-excluded. This is when you ask the company to stop you from gambling with them for a period of time. The exclusion will last for a minimum of least six months. Self-exclusion can be used if you think you have a problem with gambling and want help to stop. [The Gambling Commission] are also working with industry representatives to develop a national online self-exclusion scheme.
  • Read the terms and conditions: Did you know almost 80% of gamblers haven’t read the terms and conditions on the websites they are gambling on? By taking the time to read the T&Cs, you can ensure you understand exactly what you are gambling on, and what restrictions are attached to promotions and bonus offers (such as a minimum spend level before the bonus is paid) – this will help you make an informed decision.
  • Make sure the website you’re gambling with is licensed: Make sure you’re gambling with a Gambling Commission licensed business. This means you’ll be protected by gambling and consumer protection rules in Great Britain. Licensed gambling businesses must display that they are licensed and provide a link to our licence register where you can see what type of activities they are allowed to offer and also if we have taken any regulatory action against them.
  • Check how your money is protected: Any gambling business that holds customer funds must explain in their T&Cs how customer funds are protected if the business goes bust – this should help you decide who you want to gamble with.
  • Feel it’s getting too much? Talk to someone: There are a number of gambling support groups available if you feel your gambling is getting out of control or too much. More information about the signs of problem gambling can be found on the Gambleaware and Gamcare websites [You can call the National Gambling Helpline on Freephone 0808 8020 133]. They also provide general information about gambling, including how to gamble safely and where to get help if you or someone you know has problems with their gambling.

Teaming reign: A brief look at marketing convergence in online sports betting

The marketing cycle of a typical online betting firm aptly illustrates the converging nature of sports and its neighbouring industries. For instance, consider the following football narrative. A betting site buys advertisement space in a national newspaper. The online edition of that newspaper accompanies the advertisement with an active link. If a user clicks on it and access the betting site, the newspaper as an affiliate marketer will get 30% of the money that user has lost betting. In order to boost the number of users clicking on it, the paper publishes next to it a news article featuring Real Madrid on the eve of a match against Manchester United with the following headline: ‘Cristiano Ronaldo scored in 4 of his last 5 visits to Old Trafford’. Now, the journalist shares the link to that piece of news on Twitter, predicting a goal from Ronaldo, with a non-negligible likelihood that he or she is in business with a betting company, according to what was found in a 2014 sample of the ten most followed sports journalists in Spain.

The tweet might be read by someone at home, or even in the stands of a stadium as the game is being played, in which case a betting company might have sponsored the installation of high-speed Wi-Fi connection to facilitate bets. The bet will be preferably made in the proprietary app of the team, who partnered with the betting firm for an amount of money in exchange for adorning the stadium with the brand’s logo, although exclusivity in the electronic banners surrounding the pitch is not possible since the home team must comply with the different betting partners of the league.

Generating-Income-from-Sports-Betting-Affiliate-Programs

Chances are that those at home watching the game on television will hear a litany of statistics about the game delivered by the commentators, provided by a data company like Perform or Dimension Data, who in turn also provide those same data to betting companies, and which are also in a partnership with the league. It is these same data that will inform a fantasy league competition, which also sponsors the league. It might be the case that among the members of the family watching the game at home there are minors who cannot legally gamble for money, for whom a social gaming alternative is also available that can smooth the transition towards real money gambling in the future.

Also, for some demographic groups, sports betting might not be as appealing as eSports, but sport teams have already started sponsoring players in those competitions. When the match has finished, fans can watch further gambling commercials such as ones related to poker, conveniently introduced by sportsmen such as Neymar, Rafael Nadal or Cristiano Ronaldo, or indulge themselves in a little trading in the forex market company Xtrade endorsed by Cristiano Ronaldo himself.

A potential downside of such convergence might be the errors derived by a faulty identification of each product’s category and characteristics. The border between not-for-real-money social gaming on sports and real money gambling might not be obvious, especially when gambling gradually approaches gaming with more gamification attributes being added to the betting experience, and simultaneously, gaming approaches gambling by implementing real or virtual money in-app micro purchases or simulating gambling environments. Blurred lines might impact the understanding of what is information and what is promotion, as has been observed with children having problems distinguishing gambling advertising from non-advertising content (as demonstrated by Helena Sandberg and her colleagues in a 2011 issue of the International Journal of Communication). Another downside could be the transference of positive attributes from sport to other markets (most notably financial trading or poker in the example above), that buy their way into the mental association by, for instance, becoming a named sponsor of a sporting competition.

However, neither the situational and structural characteristics nor the cross-marketing convergence act as singular factors determining online betting behaviour. More likely, they work by aggregation, populating a marketing and advertising ecosystem that far from curtailing other gambling motivating factors – individual factors such as the biological, psychological or social characteristics of the gambler – it facilitates them.

Doctor, doctor: What can British GPs do about problem gambling?

A study published in the British Journal of General Practice in March 2017 reported that of 1,058 individuals surveyed in GP waiting rooms in Bristol (UK), 0.9% were problem gamblers and that a further 4.3% reported gambling problems that “were low to medium severity”. This is in line with other British studies carried out over the last decade which have reported problem gambling prevalence rates of between 0.5% and 0.9%.

I have long argued that problem gambling is a health issue and that GPs should routinely screen for gambling problems. Back in 2004, I published an article in the British Medical Journal about why problem gambling is a health issue. I argued that the social and health costs of problem gambling were (and still are) large at both individual and societal levels.

uk-gambling-trade-bodies-unite-to-improve-responsible-gaming

Personal costs can include irritability, extreme moodiness, problems with personal relationships (including divorce), absenteeism from work, neglect of family, and bankruptcy. Adverse health consequences for problem gamblers and their partners include depression, insomnia, intestinal disorders, migraine, and other stress related disorders. In my BMJ article I also noted that analysis of calls to the GamCare national gambling helpline indicated that a small minority of callers reported health-related consequences as a result of their problematic gambling. These included depression, anxiety, stomach problems, and suicidal ideation. Obviously many of these medical problems arise through the stress of financial problems but that doesn’t make it any less of a health issue for those suffering from severe gambling problems.

Research published in the American Journal of Addictions has also shown that health-related problems can occur as a result of withdrawal effects. For instance, one study by Dr. Richard Rosenthal and Dr. Henry Lesieur found that at least 65% of pathological gamblers reported at least one physical side effect during withdrawal, including insomnia, headaches, loss of appetite, physical weakness, heart racing, muscle aches, breathing difficulty, and chills.

Based on these findings, problem gambling is very much a health issue that needs to be taken seriously by all in the medical profession. GPs routinely ask patients about smoking cigarettes and drinking, but gambling is something that is not generally discussed. Problem gambling may be perceived as a grey area in the field of health, and it is therefore very easy for those in the medical profession not to have the issue on their wellbeing radar. If the main aim of GPs is to ensure the health of their patients, then an awareness of gambling and the issues surrounding it should be an important part of basic knowledge and should be taught in the curriculum while prospective doctors are at medical school. One of the reasons that GPs don’t routinely screen for problem gambling is because they are not taught about it during their medical training and therefore do not even think about screening for it in the first place. As I recommended in a report commissioned by the British Medical Association, the need for education and training in the diagnosis, appropriate referral and effective treatment of gambling problems must be addressed within GP training. More specifically, GPs should be aware of the types of gambling and problem gambling, demographic and cultural differences, and the problems and common co-morbidities associated with problem gambling. GPs should also understand the importance of screening patients perceived to be at increased risk of gambling addiction, and should be aware of the referral and support services available locally.

I also recommended that treatment for problem gambling should be provided under the NHS (either as standalone services or alongside drug and alcohol addiction services) and funded by gambling-derived profit revenue.

Back in 2011, Dr. Jane Rigbye and myself published a study using Freedom of Information requests to ask NHS trusts if they had ever treated pathological gamblers. Only 3% of the trusts had ever treated a problem gambler and only one trust said they offered dedicated help and support. I’m sure if we repeated the study today, little will have changed.

It is evident that problem gambling is not, as yet, on the public health agenda in the UK. NHS services – including GP surgeries – need to be encouraged to see gambling problems as a primary reason for referral and a valid treatment option. Information about gambling addiction services, in particular services in the local area, should be readily available to gamblers and GP surgeries are a good outlet to advertise such services. Although some gambling services (such as GamCare, the gambling charity I co-founded) provide information to problem gamblers about local services, such information is provided to problem gamblers who have already been proactive in seeking gambling help and/or information. Given that very few GPs could probably treat a problem gambler, what they must have is the knowledge of who they can refer their patients to.

It takes all sports: A brief look at sport-related betting

Over the past year I have been carrying out research with my Spanish colleague – Dr. Hibai Lopez-Gonzalez – into problematic sports betting and sports betting advertising which has already produced a number of papers (see ‘Further reading’ below) and with many more to come. One of the issues we have faced in contextualising our work is that there is no such concept as sport-related problem gambling in prevalence surveys because problem gambling is assessed on the totality of gambling experiences rather than a single activity. For instance, in the three British Gambling Prevalence Surveys (BGPSs) conducted since 1999, sport-related gambling is subsumed within a number of different gambling forms: ‘football pools and fixed odds coupons’, ‘private betting’, and ‘other events with a bookmaker’. The 2010 BGPS (which I co-authored) included ‘sports betting’ as a category, along with ‘football pools’ (no coupons), ‘private betting’, ‘spread betting’ (which can include both sports or financial trading). In addition, the 2010 BGPS added a new category under online gambling activities to include ‘any online betting’. More recently, the Health Survey for England also introduced a new category: ‘gambling on sports events (not online)’.

Unknown

Despite these limitations, some evidence can be inferred from gambling activity by gambling type. In 2014, Heather Wardle and her colleagues combined the gambling data from the Health Survey for England and the Scottish Health Survey. They reported that among adult males aged 16 years and over during a 12-month period, 5% participated in offline football pools, 8% engaged in online betting (although no indication was made about whether this only involved sport), and 8% engaged in sports events (not online). The categories were not mutually exclusive so an overlapping of respondents across categories was very likely. A similar rate was found in South Australia in a 2013 report the Social Research Centre with those betting on sports over the past year accounting for 6.1% of the adult population, an increase from the 4.2% reported in 2005.

In Spain, the Spanish Gambling Commission (Direccion General de Ordenacion del Juego [DGOJ] reported that 1.5% of the adult (male and female) population had gambled online on sports in 2015. This is a significantly lower proportion compared with the British data, although the methodological variations cannot be underestimated. Spanish data also shows that, among those who have gambled online on a single gambling type only, betting on sports is the more prevalent form with up to 66% of those adults.

In France, the data on the topic only focuses on those who gamble rather than examining the general population of gamblers and non-gamblers. Among online gamblers, Dr. Jean-Michel Costes and colleagues reported in a 2011 issue of the journal Tendances that 35.1% had bet on sports during the last 12 months. In another French study by Costes and colleagues published in a 2016 issue of the Journal of Gambling Studies, sports betting represented 16.4% of the gambling cohort, although again, the representativeness of sports betting behaviour among the general gambling and non-gambling population could not be determined.

Due to the aforementioned shortcomings in the definition of sport-related gambling, there is only fragmented empirical evidence concerning the impact of sports-related problem gambling behaviour. For instance, in 2014, Dr. Nerilee Hing noted that clinical reports indicate that treatment seeking for sports-related problem gambling had grown in Australia. In British Columbia (Canada), a 2014 survey by Malatests & Associates for the Ministry of Finance reported that 23.6% of at-risk or problem gamblers had gambled on sports either offline or online. A smaller proportion (16.2%) was found in the Spanish population screened in the national gambling DGOJ survey, except this subgroup was entirely composed of online bettors.

In a 2011 study published in International Gambling Studies with patients from a pathological gambling unit within a community hospital in Barcelona, Dr. Susana Jiménez-Murcia and her colleagues found that among those who had developed the disorder gambling online only (as opposed to those who gamble both online/offline or offline only), just over half (50.8%) were sport bettors. Those who gambled online only (on any activity) and those that only gambled online on sports events represented a small minority of the total number of problem gamblers. Overall, there is relatively little research on this sub-group of gamblers therefore I and others will be monitoring the evolution of this trend as the online gambling population grows.

Games without frontiers: A brief look at the psychology of play

In a previous blog I examined my favourite board game (Scrabble) and the extent to which someone could become addicted to it. Today’s blog takes a broader look at the psychology of play more generally. Arguably, many of the topics that I research involve the psychology of playing games with video games and gambling games being my two most obvious areas of interest.

It’s been argued by myself (and others) that the ritualized play of several childhood games provides ‘training’ in the acquisition of gambling behaviour and that some games are pre-cursors to actual gambling (e.g., playing marbles, card flipping, etc.). Some authors (such as Igor Kusyszyn) hold the view that gambling is in itself ‘adult play’. Unsurprisingly, Freud was one of the first people to concentrate on the ‘functions’ of play and concluded that play in all its varieties (a) provides a wish-fulfilment, (b) leads to conflict reduction, (c) provides temporary leave of absence from reality, and (d) brings about a change from the passive to the active.

Unknown

Since Freud, most psychologists have concentrated on the idea of ‘conflict reduction’ and in doing so have ignored his other three postulations. A more modern approach in the 1970s by Mihalyi Czikszentmihalyi asserted that during play a person can “concentrate on a limited stimulus field, in which he or she can use skills to meet clear demands, thereby forgetting his or her own problems and separate identity” (and provides one of the reasons that a small minority of people can develop problems playing games). Seminal research on the sociology of play by Roger Caillois states notes that play is a “free and voluntary activity”, “a source of joy and amusement” and “bounded by precise limits of time and space” whereas Erving Goffman views it as a “world building activity”.

Games provide the opportunity to prove one’s superiority, the desire to challenge and overcome an obstacle, and a medium by which to test one’s skill, endurance and ingenuity. Games, unlike some activities (including life itself!), tell us whether we have won or lost. As observed by James Smith and Vicki Abt in the 1980s:

“…in the context of a competitive and materialistic culture that has become increasingly regimented and standardized with little room for individual creativity and personal achievement, games (including gambling) offer the illusion of control over destiny and circumstance”.

Perhaps the best categorisation of game types was formulated by Roger Caillois who listed four classifications – agon (competition), alea (chance), mimicry (simulation), and ilinx (vertigo). In the context of games involving gambling, alea and agon are crucial in that they offer a combination of skill, chance and luck. As was previously asserted, most people desire opportunities to test their strength and skill against an adversary, and those games which offer a component of skill or talent combined with luck and chance provide the most favourable conditions. This is particularly prevalent in males who are deemed ‘masculine’ if during the socialization process they show (socially) important traits such as courage, independence, and bravery.

According to Caillois, play is “an occasion of pure waste: waste of time, energy, ingenuity, skill, and often of money” and is a “free and voluntary activity that occurs in a pure space, isolated and protected from the rest of life”. According to Caillois, play is best described by six core characteristics:

  • It is free, or not obligatory.
  • It is separate (from the routine of life) occupying its own time and space.
  • It is uncertain, so that the results of play cannot be pre-determined and so that the player’s initiative is involved.
  • It is unproductive in that it creates no wealth and ends as it begins.
  • It is governed by rules that suspend ordinary laws and behaviours and that must be followed by players.
  • It involves make-believe that confirms for players the existence of imagined realities that may be set against ‘real life’.

Back in 2000, I published an article on the psychology of games in Psychology Review and what makes a good game. I noted that:

  • All good games are relatively easy to play but can take a lifetime to become truly adept. In short, there will always room for improvement.
  • For games of any complexity there must be a bibliography that people can reference and consult. Without books and magazines to instruct and provide information there will be no development and the activity will die.
  • There needs to be competitions and tournaments. Without somewhere to play (and likeminded people to play with) there will be little development within the field over long periods of time.
  • Finally – and very much a sign of the times – no leisure activity can succeed today without corporate sponsorship of some kind.

I was recently interviewed by Lucy Orr for an article on board games for The Register – particularly about the psychology of winning. For instance, why is winning so important? I responded to Orr by pointing out that winning makes us feel good both psychologically and physiologically. Winning something – especially if it is a result of something skilful rather than by chance – can feel even better (unless the chance winning is something life changing like winning the lottery). Winning something using your own skill can demand respect from other competitors and brings about esteem (that can feed into one’s own self-esteem). Winning can be a validation that what you are doing is worthwhile. Other parts of my interview were not used.

I was asked whether beating other people makes winning more rewarding? Of course it does. Any time we engage in a behaviour that feels good we want to do it again (and again). Winning can be reinforcing on many different levels. There may be financial rewards, social rewards (peer praise, admiration and respect from others), psychological rewards (feeling better about oneself and feeling that the activity is a life-affirming and life-enhancing activity that feeds into self-esteem), and physiological rewards (increases in adrenaline and serotonin that trigger dopamine and makes us feel happy).

For some people, winning can become addictive. You can’t become addicted to something unless you are constantly reinforced and rewarded for engaging in the behaviour, and (as mentioned above) there are many different types of rewards (e.g., financial, social, psychological and physiological). Any (or all of these) could lead to repetitive and habitual behaviour and in a small minority of cases be addictive. However, as I have noted in a number of my papers, doing something to excess is not addiction. The difference between a healthy excessive enthusiasm and an addiction is that excessive enthusiasms add to life and addictions take away from it. For most people, winning behaviour – particularly in the context of playing board games – will be highly rewarding without being in any way problematic

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.

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.

Don’t blame the game: Parents, videogame content, and age ratings

Back in March 2015, BBC News reported that parents of children in 16 Cheshire county schools had been sent a letter saying that head teachers would report them to the authorities if they allowed their children to play videogames that are rated for adults (i.e., games that have an ‘18’ rating). The teachers claimed that popular games like Grand Theft Auto and Call of Duty are too violent to be played by those under the age of 18 years. They also stated that such games increased sexualised behaviour and left children vulnerable to sexual grooming. The schools also threatened to report parents who let their children play such games because it was a form of parental neglect. The author of the letter, Mary Hennessy Jones, was quoted as saying that:

“We are trying to help parents to keep their children as safe as possible in this digital era. It is so easy for children to end up in the wrong place and parents find it helpful to have some very clear guidelines”.

I’m sure the letter to parents was written with the best of intentions but as a parent of three ‘screenagers’ and someone that has spent almost three decades researching the effects of video games on human behaviour, this appears to be a very heavy-handed way to deal with the issue. Although it is illegal for any retailer to sell ‘18’ rated games to minors, it is not illegal for children to play such games, or illegal for parents to allow their children to play such games. Many parents need to be educated about the positives and negatives of playing video games but reporting them to the “authorities” is not the right way forward.

Back in the early 1990s I was probably the only academic in the UK carrying out scientific research on children’s video game playing. In fact, I was proud of my role in getting age ratings onto all video games in the first place, and for writing the text for educational information leaflets for parents (outlining the effects of excessive playing of such games) sponsored by the National Council for Educational Technology. There are many positive benefits of playing video games (something that I wrote about in a previous article for The Conversation).

I know from first-hand experience that children often play games that are age-inappropriate. Two years ago, my (then) 13-year old son said he was the only boy in his class that did not play or own the Call of Duty video game. This is also borne out by research evidence. One study that I was involved in found that almost two-thirds of children aged 11- to 13-years of age (63%) had played an 18+ video game. Unsurprisingly, boys (76%) were more likely than girls (49%) to have played an 18+ video game. Children were also asked about how often they played 18+ video games. Of the two-thirds who had played them, 8% reported playing them “all the time”, 22% reported playing them “most of the time”, 50% reported playing them “sometimes”, 18% reported playing them “hardly ever”. Again, boys were more likely than girls to play 18+ video games more frequently. Children were asked how they got access to 18+ plus video games. The majority had the games bought for them by family or friends (58%), played them at a friend’s house (35%), swapped them with friends (27%), or bought games themselves (5%). This research certainly appears to suggest that parents and siblings are complicit in the playing of age-inappropriate games.

There is a growing amount of scientific literature that has examined the content of video games designed for adults. For instance, a study led by Dr. Kimberley Thompson and published in the Archives of Pediatric and Adolescent Medicine attempted to quantify the depiction of violence, blood, sexual themes, profanity, substances, and gambling in adult (18+) video games and to assess whether the actual game content matched the content descriptor on the packaging. Although content descriptors for violence and blood provided a good indication of content in the 36 games examined, the authors concluded that 81% of the games studied (n=29) lacked content descriptors of other adult content. Other studies carried out by the same research team have found that adult content can be found in lots of games aimed at young children and teenagers.

Another study led by Dr. David Walsh published in Minerva Pediatrica tested the validity of media rating systems (including video games). Results showed that when the entertainment industry rated a product as inappropriate for children, parents also agreed that it was inappropriate. However, parents disagreed with many industry ratings that were designated as containing material as suitable for children. The products rated as appropriate for adolescents by the industry were of the greatest concern to parents.

The issue of children and adolescents playing 18+ games is no different from the debates about children and adolescents watching 18+ films. However, based on anecdotal evidence appears that parents are more likely to adhere to age ratings on films than they are on video games. This is one area that both media researchers and media educators need to inform parents to be more socially responsible in how they monitor their children’s leisure activity. A school sending out a threatening letter to parents is unlikely to change parental behaviour. Education and informed debate is likely to have a much greater effect in protecting our children from the potential harms of video game playing.

The song and binding mode: Musical hallucinations in video game playing

According to a 2015 review in the journal Frontiers in Psychology by Jan Coebergh and colleagues, musical hallucinations (MHs) “are auditory hallucinations characterized by songs, tunes, melodies, harmonics, rhythms, and/or timbres…and that the mechanisms responsible for the mediation of MH are probably diverse”. While Danilo Vitorovic and Jose Biller reported in a 2013 issue of Frontiers in Neurology that the prevalence rate of MHs among the general population is at present unknown and/or rare, ‘involuntary musical imagery’ (INMI) is thought to be more commonplace. For instance, in a 2012 Finnish study in the journal Psychology of Music, Lassi Liikkanen reported that 89% of the total sample (n=12,519) reported experiencing INMI at least once a week. Music hallucination prevalence rates among various groups have been reported including obsessive-compulsive disorder patients (41%; Journal of Clinical Psychiatry, 2004), elderly people with auditory problems (2.5%; International Journal of Geriatric Psychiatry, 2002), and general hospital setting patients (0.16%; Psychosomatics, 1998).

Although Coebergh and colleagues described MHs, they were not explicitly defined. In a review in a 2014 issue of the Journal of Medical Case Reports, Woo and colleagues defined MHs as complex auditory perceptions in the absence of an external acoustic stimulus and are often consistent with previous listening experience” whereas the 2013 review by Vitorovic and Biller (see above) noted that MHs represent a specific form of auditory hallucinations whereby patients experience formed songs, instrumental music, or tunes, without an external musical stimulus”. In a 2015 paper in the journal Psychomusicology: Music, Mind, and Brain, Tim Williams provided a classification of INMI and noted they cover a number of different types of involuntary musical experience (including MHs). Despite the lack of detailed definition, it is known that MHs occur within the context of an individual’s culture and are often viewed by those experiencing them as intrusive and sometimes unpleasant.

unknown

In 2015, Dr. Angelica Ortiz de Gortari and I wrote a commentary paper on musical hallucinations in videogame playing in response to the review by Coebergh and colleagues. As far as we were aware, we noted that no review paper examining musical hallucinations had ever included papers referring to musical hallucinations arising from playing video games. The earliest report in the psychological literature is by Sean Spence (published in 1993 in the Irish Journal of Psychological Medicine) who reported the case of a 20-year-old female patient with a family history of psychosis. She presented with persecutory delusions, suicidal ideation, violent behaviour and third-person auditory hallucinations comprising 48 hours of constant MHs from the Mario Brothers videogame that developed into delusional thoughts. No drugs were found in her urinary system and her EEG was normal when MHs occurred. The MHs from the videogame decreased within 48 hours of treatment (using antidepressants and neuroleptics).

More recently, a series of papers by Dr. Ortiz de Gortari and I examined Game Transfer Phenomena (GTP). GTP research has demonstrated how the videogame can keep on playing even after the game has been turned off. GTP are non-volitional phenomena (e.g., altered perceptions, automatic mental processes, and involuntary behaviors). In an analysis of over 1600 gamers’ self-reports, our research has shown that videogame playing can lead to (i) perceptual distortions of physical objects, environments, and/or sounds, (ii) misperceptions of objects and sounds that are similar to those in the videogame, (iii) interpretation of events in real life contexts that utilize the logic of the videogame, (iv) ghost perceptions and sensations of images, sounds, and tactile experiences, and (v) involuntary actions and behaviors based on experiences from the videogame.

One study that we published in a 2014 issue of the International Journal of Cyber Behavior, Psychology and Learning specifically examined auditory GTP experiences. Gamers’ experiences identified as GTP in one or more modalities (e.g., visual, auditory) were collected from 60 online videogame forums over seven months. Of these, there were 192 auditory experiences from 155 gamers collected. The largest numbers of experiences (90%) were identified as involuntary auditory imagery. This manifested as hearing music (n = 73), sound (n = 83), or voices from within the game (n = 12). Some experiences were triggered by external cues associated with the game, while others were not. Experiences with music included hearing high pitch music in addition to calm and classical music.

Music from the videogames was usually experienced persistently, while sound effects or voices appeared to have occurred more episodically. Hearing the music persistently provoked sleep deprivation, annoyance, and uncertainty. When the music was re-experienced very vividly, the gamers attributed them to external sources associated with the videogame. More specifically, when auditory cues were associated with adverse videogame content, they resulted in irrational thoughts, reactions and changes in behaviour. In many cases, the gamers said that they had been playing intensively (i.e., either playing long sessions or playing frequently). Previous studies have linked hearing music in absence of auditory stimuli with the recent or repeated exposure to music (see ‘Further reading’ below including: Gardner, 1985; Gerra et al., 1998; Hyman et al., 2012).

In our study, one gamer said that he heard the sound of music coming out from the speakers so he stood up to check them while another heard music from Pokémon when vacuuming. It also appears that musical hallucinations can cross sensory modalities. For instance, some gamers have reported hearing music while seeing images from the video game. An online survey about GTP with a convenience sample of 2,362 gamers found that hearing music from videogames when not playing were the more prevalent (74%) than hearing sounds (65.0%) or voices (46%) when not playing (Ortiz de Gortari & Griffiths, 2015b).

Based on what is known empirically, our paper concluded that (i) MHs from videogame playing – although not well documented – appear to be relatively commonplace among gamers and prevalence appears to be higher than found in other populations, (ii) individual interpretation of MHs from videogames are influenced by the meanings and uses of auditory cues in the videogames, (iii) MHs can manifest beyond one sensory modality and has been reported across-sensory channels (e.g., hearing music while seeing ghost images from the game), (iv) there is little evidence that MHs among videogame players are linked to other underlying pathology (e.g., epilepsy, psychiatric disorder, etc.), (v) those researching in the field of MHs and INMI appear to have overlooked the literature on these phenomena related to videogame playing, and (vi) better definitions are needed for MHs and a distinction between MHs and INMI is required.
