Problem gambling on the internet: implications for internet gambling policy in North America

The proportion of North American gamblers who choose to gamble on the internet is increasing at a dramatic rate. Unfortunately, however, relatively little is known about the characteristics of these individuals or their propensity for problem gambling. Past studies predict that internet gamblers are especially at risk for developing gambling problems and that a substantial proportion of them already can be properly classified as problem gamblers. This article investigates this issue using data collected from an internet-based survey administered to 1920 American, Canadian and international internet gamblers. Confirming predictions of a relationship between internet gambling and problem gambling, it finds that 42.7 percent of the internet gamblers in the sample can be classified as problem gamblers. In light of the findings, and bearing in mind the recommendations made by other gambling researchers, it concludes with a discussion of issues and cautions for governments to heed when crafting internet gambling policies.

A comparative profile of the Internet gambler: Demographic characteristics, game-play patterns, and problem gambling status

Overcoming the methodological limitations of many previous studies, the present study employs a two-phased approach to data collection, and a weighted approach to data analysis, thereby obtaining survey data from 1954 Internet gamblers and 5967 non-Internet gamblers. Using this data, the authors examine: (1) the comparative demographic and health characteristics of Internet versus land-based gamblers; (2) the characteristics predictive of Internet gambling; (3) the game-play patterns of Internet gamblers; (4) the comparative gambling expenditures of Internet versus land-based gamblers; and (5) the comparative rate of problem gambling among Internet versus land-based gamblers. The article concludes with a discussion of the methodological implications the present study holds for future research. Moreover, in light of the key finding that Internet gamblers are three to four times more likely to have a gambling problem, the article concludes with a discussion of relevant theoretical and policy implications.

A digital revolution: Comparison of demographic profiles, attitudes and gambling behavior of Internet and non-Internet gamblers

Internet gambling is one of the fastest growing sectors of e-commerce and rapidly growing as a mode of gambling. Although Internet gambling is characterized by high levels of customer choice, little is known about Internet gamblers or their engagement with Internet and non-Internet forms of gambling. Regulators are struggling to respond to Internet gambling given that little is known about the impact of this mode of gambling on the existing gambling market, who is gambling online and how. This paper presents one of the largest studies of Internet gambling; an online survey completed by 6682 Australian gamblers. Results show that Internet gamblers are a heterogeneous group, although there is a tendency for Internet gamblers to be male, have high incomes and be well educated. Internet gamblers have more positive attitudes towards gambling and are more highly involved gamblers, engaging in many different gambling activities in both online and offline forms. However, a proportion of Internet gamblers prefer the privacy and anonymity of Internet gambling and do not like land-based venues, suggesting that Internet gambling is creating a new market of gambling customers. Understanding the impact of this new mode of gamblers on existing gamblers and new players is important to contribute to the appropriate regulation of this activity.

‘How Much Money Do You Spend on Gambling?’ The Comparative Validity of Question Wordings Used to Assess Gambling Expenditure

Gambling expenditure is a commonly asked question in jurisdiction‐wide surveys of gambling behaviour and in surveys of household spending. However, the validity of self‐reported gambling expenditure is questionable due to the fact that these expenditures usually do not match actual gambling revenue. The present study asked a random sample of 2424 Ontario adult gamblers, in 12 different ways, about past month gambling expenditure. The relative validity of each question format was subsequently established by the correspondence of reported gambling expenditures with actual Ontario gambling revenue, as well as with amounts obtained by prospective diaries. Slight variations in question wording resulted in significant variation in reported expenditure amounts. However, certain question wordings elicited amounts closer to actual revenues and are therefore recommended for use in future surveys.

The prevalence and determinants of problem gambling in Australia: assessing the impact of interactive gambling and new technologies

New technology is changing the nature of gambling with interactive modes of gambling becoming putatively associated with higher rates of problem gambling. This paper presents the first nationally representative data on the prevalence and correlates of problem gambling among Australian adults since 1999 and focuses on the impact of interactive gambling. A telephone survey of 15,006 adults was conducted. Of these, 2,010 gamblers (all interactive gamblers and a randomly selected subsample of those reporting land-based gambling in the past 12 months) also completed more detailed measures of problem gambling, substance use, psychological distress, and help-seeking. Problem gambling rates among interactive gamblers were 3 times higher than for noninteractive gamblers. However, problem and moderate risk gamblers were most likely to attribute problems to electronic gaming machines and land-based gambling, suggesting that although interactive forms of gambling are associated with substantial problems, interactive gamblers experience significant harms from land-based gambling. The findings demonstrate that problem gambling remains a significant public health issue that is changing in response to new technologies, and it is important to develop strategies that minimize harms among interactive gamblers.

The association between childhood maltreatment and gambling problems in a community sample of adult men and women.

The association between childhood maltreatment and gambling problems was examined in a community sample of men and women (N = 1,372). As hypothesized, individuals with gambling problems reported greater childhood maltreatment than individuals without gambling problems. Childhood maltreatment predicted severity of gambling problems and frequency of gambling even when other individual and social factors were controlled including symptoms of alcohol and other drug use disorders, family environment, psychological distress, and symptoms of antisocial disorder. In contrast to findings in treatment-seeking samples, women with gambling problems did not report greater maltreatment than men with gambling problems. These results underscore the need for both increased prevention of childhood maltreatment and increased sensitivity towards trauma issues in gambling treatment programs for men and women.

Association of functional variants in the dopamine D2-like receptors with risk for gambling behaviour in healthy Caucasian subjects.

Pathological gambling (PG) is an impulse control disorder with suggestive genetic vulnerability component. We evaluated the association of genetic variants in the dopaminergic receptor genes (DRD1-3s) with risk for gambling in healthy subjects using the Canadian Problem Gambling Index (CPGI). Healthy Caucasian subjects who had gambled at least once in their lifetime (n=242) were included in the analysis. Gender was not associated with the CPGI, while younger age was associated with higher CPGI scores. We have found that none of the single polymorphisms investigated on DRD1 and DRD3 were associated with CPGI scores in healthy subjects. However, we observed trends for association on the TaqIA/rs1800497 polymorphism (P=0.10) and the haplotype flanking DRD2 (G/C/A rs11604671/rs4938015/rs2303380; P=0.06). Both trends were associated with lower CPGI score. Our results provide further evidence for the role of dopamine D2-like receptor in addiction susceptibility.

Internet gambling policy in critical comparative perspective: the effectiveness of existing regulatory frameworks

Following the rapid progression of Internet gambling, governments internationally are struggling to create and enact appropriate and effective regulations. A situation of inter-jurisdictional inconsistency exists and regulatory frameworks are constantly changing, with international policies of prohibition, legalization or partial legalization, or imprecise legal limbo. The ambiguity of the current situation and questionable effectiveness of policies in place makes it difficult for gambling operators, treatment providers, players and other stakeholders to formulate appropriate responses to online gambling. This article aims to bring some clarity and offer guidance for the effective implementation of gambling policy by examining the comparative evolution of Internet gambling in Australia and Canada, and the respective social, legal, economic and political responses. The differences in the development of online gambling highlight the unique paths possible, yet the similarities between these jurisdictions provide key examples of how policymakers, gambling operators, researchers and consumers can respond to this phenomenon.

The impact of internet gambling on gambling problems: a comparison of moderate-risk and problem Internet and non-Internet gamblers.

Numerous studies have reported higher rates of gambling problems among Internet compared with non-Internet gamblers. However, little research has examined those at risk of developing gambling problems or overall gambling involvement. This study aimed to examine differences between problem and moderate-risk gamblers among Internet and non-Internet gamblers to determine the mechanisms for how Internet gambling may contribute to gambling problems. Australian gamblers (N = 6,682) completed an online survey that included measures of gambling participation, problem gambling severity, and help seeking. Compared with non-Internet gamblers, Internet gamblers were younger, engaged in a greater number of gambling activities, and were more likely to bet on sports. These differences were significantly greater for problem than moderate-risk gamblers. Non-Internet gamblers were more likely to gamble on electronic gaming machines, and a significantly higher proportion of problem gamblers participated in this gambling activity. Non-Internet gamblers were more likely to report health and psychological impacts of problem gambling and having sought help for gambling problems. Internet gamblers who experience gambling-related harms appear to represent a somewhat different group from non-Internet problem and moderate-risk gamblers. This has implications for the development of treatment and prevention programs, which are often based on research that does not cater for differences between subgroups of gamblers.

Stacked Deck: an effective, school-based program for the prevention of problem gambling.

School-based prevention programs are an important component of problem gambling prevention, but empirically effective programs are lacking. Stacked Deck is a set of 5–6 interactive lessons that teach about the history of gambling; the true odds and “house edge”; gambling fallacies; signs, risk factors, and causes of problem gambling; and skills for good decision making and problem solving. An overriding theme of the program is to approach life as a “smart gambler” by determining the odds and weighing the pros versus cons of your actions. A total of 949 grade 9–12 students in 10 schools throughout southern Alberta received the program and completed baseline and follow-up measures. These students were compared to 291 students in 4 control schools. Four months after receiving the program, students in the intervention group had significantly more negative attitudes toward gambling, improved knowledge about gambling and problem gambling, improved resistance to gambling fallacies, improved decision making and problem solving, decreased gambling frequency, and decreased rates of problem gambling. There was no change in involvement in high risk activities or money lost gambling. These results indicate that Stacked Deck is a promising curriculum for the prevention of problem gambling.
