Mapping the proportional distribution of gambling-related harms in a clinical and community sample

Excessive gambling results in a range of diverse harms experienced by individuals and their family members. However, little consideration has been given to specifically assessing such harms. Despite recent attempts to comprehensively ‘list’ and describe the ‘wide net’ of specific harms, what remains particularly unclear is the best way to measure the presence of harm and quantify its relationship to gambling. This article proposes a two-step method for quantifying gambling-related harm. From the literature, 104 questions assessing 48 items of harm were categorized into seven domains. Items were administered to 391 clinical and 151 community gamblers. Results suggest that while high-impact harms such as suicide and divorce are commonly associated with problem gambling, the reported frequency is low. Most gamblers sustain low-impact harms such as reduced savings and worry. This study presents the evaluation of specific gambling-related harms distributed in a clinical and community sample taking into account severity and its relationship to gambling behaviours. It is concluded that gambling-related harms negatively impact on quality of life with a minority suffering more severe harms. It is argued that the proposed two-step methodology provides a basis for developing a psychometrically valid measure of gambling-related harm.     

Thoughts and acts of self-harm,and suicidal ideation,in online gamblers

Gambling problems have been linked to suicidal ideation and enhanced risk of suicide attempts. However, we know very little about the factors associated with either thoughts or acts of self-harm amongst people who gamble. A web-based study of 4125 online gamblers (79% males; mean age 35.5 years), analysed using hierarchical multiple regression, revealed that self-reported non-gambling-related self-harm was negatively related to age and marital status, and positively related to problematic alcohol use. Self-reported acts of self-harm both related and unrelated to gambling were associated with drug misuse. Thoughts and acts of gambling-related self-harm were associated with problem gambling, gambling involvement and parental problem gambling. All types of self-harm were associated with mood disorder symptoms, unemployment and certain gambling motivations. When tailoring assessment and interventions for individuals at risk for gambling-related deliberate self-harm, it is important to recognize that contributory factors may include some that differ from those for deliberate self-harm in general, and that there is potential value in evaluating gambling involvement and motivations, and history of parental gambling.     

Gambling-Related Harms Among Adolescents: A Population-Based Study

Internationally, and also in Europe, adolescent gambling is increasingly recognized as an important public health issue. Most research on adolescent gambling, however, is prevalence-focused and population-based studies are scarce. Few studies have examined gambling-related harms among adolescents. In a national sample, we examined self-experienced harms related to gambling and the relationship between reported harms and gambling behavior among Finnish adolescents. A national survey of 12–18-year-olds was conducted in Finland in 2011 (N = 4,566). Main measures were frequency of gambling and gambling-related harms reported during the past 6 months. The relationship between reported harms and gambling behavior was assessed using logistic regression analysis. Overall, 44% had gambled during the past 6 months. Of the sample, 12% were frequent gamblers (at least weekly) and 32% were occasional gamblers (monthly or less often). Compared to occasional gamblers, frequent gamblers were more likely to experience harms. The most commonly reported harms among frequent gamblers were “felt guilty or shameful due to gambling” (17%) followed by “problems with relationships” (13%) and “disruptions of daily rhythm” (10%). In age and gender-adjusted analysis, daily gamblers were significantly more likely to report all different types of harms when compared to other groups. These findings suggest that when planning and targeting youth gambling prevention and harm reduction strategies the nature and extent to which gambling may contribute to the different types of harms are important to consider.     

Does gambling type moderate the links between problem gambling,emotion regulation,anxiety, depression and gambling motives

The aim of this study is to assess the link between emotion regulation, depression, anxiety and gambling motives among a population of regular gamblers, distinguishing between strategic and chance game players. We recruited 287 regular gamblers online, including both problem (PG) and non-problem gamblers (NPG). All participants completed online questionnaires to screen for problem gambling (SOGS) and to assess emotion regulation (ERQ), anxiety and depression (HADS) and gambling motives (GMQ-F). In this sample, 33.4% of participants were PG. PG scored significantly higher than NPG on the GMQ-F (except for the social subscale) and HADS, but not in ERQ. Gamblers who played both strategic and chance games displayed more frequent and severe gambling problems and had higher depression and anxiety scores than those playing only strategic games. Overall, enhancement and financial motives and depression significantly predicted PG. Finally, the study found that gambling type moderates the relationship between problem gambling and expressive suppression, depression and gambling motives. The results show the intricate relationship between gambling motives and psychiatric symptoms (in particular, depression) in PG. Mixed and strategic gamblers share common motives, but coping, financial and enhancement were stronger among PG. Finally, they emphasize the differences between different types of gamblers.     

Games of chance or masters of illusion: multiline slots design may promote cognitive distortions

Problem gamblers often have distorted beliefs about gambling, including illusion of control and gambler's fallacy. Most multiline slots games allow players to adjust the number of wagered paylines and the amount bet per line, and over time this control may support incorrect conclusions and promote distorted gambling beliefs. We created software to run simulations of a popular multiline slots game and examined the effects of betting on single versus multiple paylines. Simultaneous multiline betting tends to produce a less varied gambling experience because it increases the frequency of legitimate wins and ‘losses disguised as wins’, while decreasing the occurrence of ‘big wins’. It also shortens consecutive series of losing spins and it prolongs the time a typical player takes to exhaust funds. Indirect control over losing streaks may give some players the false impression that they can play skilfully and predict the occurrence of wins. However, applying five different wagering strategies in our simulations showed that none had any real effect on the average percentage of wagers that would be ‘paid back’ to players as prizes. Player control over multiline slots games may lead frequent gamblers to incorrect conclusions that sustain excessive play despite recurring losses.     

Problem gambling in poker: money,rationality and control in a skill-based social game

The article explores problem gambling in poker. The distinctions between chance and skill and between bank games and social games are applied to demonstrate how poker is structurally different from most other gambling games. Bank games are organised around a central actor such as the house, the casino or the bookmaker. In social games, players compete against each other on equal statistical footing. Poker is a skill-based social game where players with superior skills may be expected to win even in the long run. Fourteen poker playing problem gamblers were recruited through a treatment program and 15 professional and recreational poker players were recruited through snowball sampling (N = 29). Through qualitative interviews, the paper shows that the particular structural composition of poker has implications for the ways problem gambling arises in poker players. It is argued that poker challenges existing theoretical conceptions about problem gambling relating to money, rationality and control.     

Validation of the Short Gambling Harm Screen (SGHS): A Tool for Assessment of Harms from Gambling

It is common for jurisdictions tasked with minimising gambling-related harm to conduct problem gambling prevalence studies for the purpose of monitoring the impact of gambling on the community. However, given that both public health theory and empirical findings suggest that harms can occur without individuals satisfying clinical criteria of addiction, there is a recognized conceptual disconnect between the prevalence of clinical problem gamblers, and aggregate harm to the community. Starting with an initial item pool of 72 specific harms caused by problematic gambling, our aim was to develop a short gambling harms scale (SGHS) to screen for the presence and degree of harm caused by gambling. An Internet panel of 1524 individuals who had gambled in the last year completed a 72-item checklist, along with the Personal Wellbeing Index, the PGSI, and other measures. We selected 10 items for the SGHS, with the goals of maximising sensitivity and construct coverage. Psychometric analysis suggests very strong reliability, homogeneity and unidimensionality. Non-zero responses on the SGHS were associated with a large decrease in personal wellbeing, with wellbeing decreasing linearly with the number of harms indicated. We conclude that weighted SGHS scores can be aggregated at the population level to yield a sensitive and valid measure of gambling harm.     

Cognitive distortions as a problem gambling risk factor in Internet gambling

The purpose of this study was to examine the role of cognitive distortions in Internet gambling. The primary objectives were to determine whether cognitive distortions predict Internet gambling and investigate whether distorted gambling-related cognitions are associated with problem gambling severity among online gamblers. Three hundred and seventy four undergraduate participants (143 online gamblers, 172 males) completed an online questionnaire looking at demographics, play-related variables (duration, frequency and expenditures of play) and cognitive distortions. Variables were entered into a logistic regression model to predict online gambling. Three variables made independent contributions to predicting Internet gambling: male gender, higher frequency of play, and cognitive distortions. A hierarchical linear regression analysis with Internet gamblers revealed that cognitive distortions accounted for a proportion of the variance in problem gambling severity beyond variance accounted for by demographic variables and level of gambling involvement. Results suggest that cognitive distortions are a risk factor in online gambling.     

Impulsivity and predictive control are associated with suboptimal action-selection and action-value learning in regular gamblers

Heightened impulsivity and cognitive biases are risk factors for gambling problems. However, little is known about precisely how these factors increase the risks of gambling-related harm in vulnerable individuals. Here, we modelled the behaviour of 87 community-recruited regular, but not clinically problematic, gamblers during a binary-choice reinforcement-learning game, to characterize the relationships between impulsivity, cognitive biases and the capacity to make optimal action selections and learn about action-values. Impulsive gamblers showed diminished use of an optimal (Bayesian-derived) probability estimate when selecting between candidate actions, and showed slower learning rates and enhanced non-linear probability weighting while learning action values. Critically, gamblers who believed that it is possible to predict winning outcomes (as ‘predictive control’) failed to use the game's reinforcement history to guide their action selections. Extensive evidence attests to the ease with which gamblers can erroneously perceive structure in the reinforcement history of games when there is none. Our findings demonstrate that the generic and specific risk factors of impulsivity and cognitive biases can interfere with the capacity of some gamblers to utilize structure when it is available in the reinforcement history of games, potentially increasing their risks of sustaining gambling-related harms.     

Analysis of EGM licensing decisions by the gambling regulator,Victoria, Australia

Gambling expansion is commonly justified in public discourse by claims of community benefit, increased employment and capital investment. Compared to other jurisdictions, the Electronic Gambling Machine (EGM) license process in Victoria, Australia, is relatively transparent and amenable to analysis. This article describes research that assessed factors relevant to EGM license decisions made by Victoria’s gambling regulator between 2007 and 2014. During the period under review, the regulator granted 144 of 154 applications, finding that approving these applications would not be detrimental to relevant communities. Most commonly cited factors supporting approvals were commitments to undertake capital works, contribute to community purposes and increase employment. The regulator overwhelmingly agreed that supportive factors would balance harms, such as problem gambling, high levels of expenditure or socio-economic disadvantage. This research demonstrates the difficulty of balancing apparently quantifiable benefits against less readily measurable gambling-related harms in regulatory decision-making. The study found that harms were poorly conceived and understood inadequately and supportive factors frequently overstated. This process may lead to unnecessarily high levels of community harm, contradicting the purposes of the relevant legislation. The article suggests that better, more consistently applied principles are required to ensure the more rigorous scrutiny of supportive factors and improved understanding of gambling harms.     

Gambling and Problem Gambling among Recently Sentenced Male Prisoners in Four New Zealand Prisons

Recently sentenced inmates in four New Zealand male prisons (N = 357) were interviewed to assess their gambling involvement, problem gambling and criminal offending. Frequent participation in and high expenditure on continuous forms of gambling prior to imprisonment were reported. Nineteen percent said they had been in prison for a gambling-related offence and most of this offending was property-related and non-violent. On the basis of their SOGS-R scores, 21% were lifetime probable pathological gamblers and 16% were probable pathological gamblers during the six months prior to imprisonment. Of the “current” problem gamblers, 51% reported gambling-related offending and 35% had been imprisoned for a crime of this type. Gambling-related offending increased with problem gambling severity. However, only five percent of problem gamblers said their early offending was gambling-related. The large majority reported other types of offending at this time. Few men had sought or received help for gambling problems prior to imprisonment or during their present incarceration. This highlights the potential for assessment and treatment programs in prison to reduce recidivism and adverse effects of problem gambling and gambling-related offending.     

Games and Gambling Involvement Among Casino Patrons

A growing literature is addressing the nature of the relationships among gambling activity, gambling involvement, and gambling-related problems. This research suggests that among the general population, compared to playing any specific game, gambling involvement is a better predictor of gambling-related problems. To date, researchers have not examined these relationships among casino patrons, a population that differs from the general population in a variety of important ways. A survey of 1160 casino patrons at two Las Vegas resort casinos allowed us to determine relationships between the games that patrons played during the 12 months before their casino visit, the games that patrons played during their casino visit, and patrons’ self-perceived history of gambling-related problems. Results indicate that playing specific gambling games onsite predicted (i.e., statistically significant odds ratios ranging from .5 to 4.51) self-perceived gambling-related problems. However, after controlling for involvement, operationally defined as the number of games played during the current casino visit and self-reported gambling frequency during the past 12 months, the relationships between games and gambling-related problems disappeared or were attenuated (i.e., odds ratios no longer statistically significant). These results extend the burgeoning literature related to gambling involvement and its relationship to gambling-related problems.     

Special features of poker

Poker is now one of the most popular types of online gambling, mostly because of its particular structural characteristics. This study aims to investigate the representations of regular poker players of the game's special features, along with their probable links with tilt (i.e. loss of control during the game) and problem gambling. Twenty-three regular poker players recruited online took part in a research interview. All interviews were recorded and fully transcribed. A quantitative lexical analysis was performed using the software Alceste®. Six classes were identified, encompassing 73% of the whole corpus. The main themes were chance vs. skill, sensations and emotions linked to poker, discovery of poker, tilt, differences between live and online gambling, and risks of excessive poker involvement. The experience of tilt appears to be an important feature of poker. Poker players also tended to report more emotional and social aspects of problem gambling than financial consequences. The results underline the structural specificities of poker through the player's representations. The role of emotions and sensations in poker, as they are both sought by the players and involved in the loss of control, may have an influence on the development and maintenance of problem gambling.     

Gambling Patterns and Problems of Gamblers on Licensed and Unlicensed Sites in France

In 2010 France enacted a law to regulate supply and consumption of online gambling. Its primary aim was to protect citizens from gambling-related harm. This study aims to assess differences in gambling patterns and related harm between online gamblers who use licensed versus unlicensed sites. Participants (N = 3860) completed a self-administered online survey on gambling practices. Pairwise logistic regressions examined the association between the legal statuses of gambling sites people patronized and demographic variables and gambling types. Multivariate logistic regression models explored associations between gambling patterns and related problems according to the legal status of sites people have gambled on. Overall, 53.7 % of online gamblers report gambling exclusively on licensed sites. Those who bet on regulated activities on unlicensed sites, versus licensed sites, are more likely to be female, younger, less educated, inactive in the labor market and are more likely to perceive their financial situation to be difficult. Gambling on unlicensed sites is associated with more intense gambling patterns and more gambling-related problems compared to licensed sites. Findings demonstrate that gambling activities carried out on state licensed sites are associated with less overall harm to gamblers. Implications of these findings on future policy are discussed and prospective research directions are outlined.     

Event frequency,excitement and desire to gamble,among pathological gamblers

In this study we compared gambling behaviour of 15 pathological gamblers (PG) and 15 non-problem gamblers (NPG) on two conditions of a commercially available slot machine. One condition used a commercially available two-second event frequency (games per minute), while the other condition used an experimental three-second event frequency. The payback percentage (wins relative to losses) and reward frequency (wins over number of games played) varied randomly across conditions. The results showed that PG had significantly higher measures than NPG on time spent gambling, excitement level and desire to play again in the two-second condition. In the three-second condition there were no differences in excitement level and desire to play again. The number of PG playing the maximum time (60 minutes) was reduced in the three-second version, and reward frequency contributed to reduction in time spent gambling. The results may have implications for understanding behavioural mechanisms of pathological gambling among slot machine players.     

The temporal relationship between gambling related beliefs and gambling behaviour: a prospective study using the theory of planned behaviour

The Theory of Planned Behaviour (TPB) has been successfully employed to investigate the role of gambling-related beliefs in the maintenance of gambling behaviour. However, there is a lack of research that examines the temporal relationships between the TPB predictor variables and gambling behaviour. Thus, the current study examines the utility of expectancies, normative beliefs, perceived behaviour control and gambling intentions in predicting gambling frequency, as assessed 12 months later. In addition, these gambling-related beliefs were reassessed at the 12-month follow-up survey to examine their stability and relationships with gambling behaviour. A total of 805 Australian adults, recruited via an online research panel, completed the baseline and follow-up online survey. Consistent with expectations, gambling-related beliefs explained gambling intentions and intentions predicted Wave 2 gambling frequency, after controlling Wave 1 gambling frequency. In relation to the stability of gambling-related beliefs, the Wave 2 measures explained additional variance in the Wave 2 gambling behaviour, although the type of beliefs associated with Wave 2 gambling frequency and problem gambling severity differed. These findings provide support for the notion that the perceived benefits of gambling and beliefs in skill are important areas to target in preventative and problem gambling initiatives.     

Near Wins Prolong Gambling on a Video Lottery Terminal

The purpose of the present study was to evaluate whether near wins can prolong gambling activity on a video lottery terminal. In a three-reel game, near wins were operationally defined as two identical symbols followed by a third different symbol. Players in an experimental condition were exposed to 27% near wins in a series of continuous losses, whereas players in a control group were exposed to none. Participants played as long as they wished, and received real money for their wins. The results showed that players in the near win condition played 33% more games than did the control group. The results of this study suggest that near wins can be added to the list of factors that may motivate people to gamble despite the probability of monetary loss.     

Volatility,House Edge and Prize Structure of Gambling Games

This study used simulations to examine the effect of prize structure on the outcome volatility and the number of winners of various game configurations. The two most common prize structures found in gambling games are even money payoff games (bet 1; win1; win 2) found on most table games and multilevel prizes structures found in gambling machine games. Simulations were set up to examine the effect of prize structure on the long-term outcomes of these games. Eight different prize structures were compared in terms of the number of winners and volatility. It was found that the standard table game and commercial gambling machines produced fairly high numbers of short term winners (1 h), but few long term winners (50 h). It was found that the typical even money game set up produced the lowest level of volatility. Of the multilevel prize structures examined, the three simulations based on commercial gambling machines were the least volatile. The results are examined in terms of the pragmatics of game design.     

A Science-Based Framework for Responsible Gambling: The Reno Model

As social observers increasingly identify gambling-related problems as a public health issue, key stakeholders need to join together to reduce both the incidence and prevalence of gambling-related harm in the community. This position paper describes a strategic framework that sets out principles to guide industry operators, health service and other welfare providers, interested community groups, consumers and governments and their related agencies in the adoption and implementation of responsible gambling and harm minimization initiatives.     

Trends in Bio-Behavioral Gambling Studies Research: Quantifying Citations

Both the National Gambling Impact Study Commission and the National Academy of Sciences have evaluated the current state of gambling studies research in general while making specific suggestions for future efforts in the psychological and biomedical areas in particular. Recognizing the importance of evaluating the state of the field on a macro level, this paper considers and categorizes several decades of psychological and biomedical gambling research. By examining the number of references to gambling in two major bibliographic databases, quantifiable trends and observations are presented about gambling-related psychological and biomedical research. Two trends in particular are salient: the rate at which gambling-related articles are published in scholarly journals is increasing, and the plurality of these articles deals with issues of cognition and personality as related to gambling.
