The prevalence and determinants of problem gambling in Australia: assessing the impact of interactive gambling and new technologies. Psychol Addict Behav. 2014;28(3):769–79. Using a nationally representative telephone survey, this paper compared problem gambling among Internet and non-Internet gamblers to reveal variables related to each. The findings demonstrate that Internet problem gamblers experience harms also related to land-based gambling and that gambling problems are related to overall involvement and intensity rather than the mode of access used.

Psychol Addict Behav. 2013;27:1092–101. Based on a large online survey, moderate-risk and problem gamblers were compared based on their use of Internet gambling. The results demonstrate that Internet gamblers who experience gambling-related harms appear to represent a somewhat different group from non-Internet problem and moderate-risk gamblers—Internet gamblers were younger, engaged in a greater number of gambling activities, and were more likely to bet on sports.

New Media Soc. 2014. doi:10.1177/1461444813518185. Based on an online survey, problem and non-problem Internet gamblers were compared. Problem gamblers were shown to represent a distinct cohort of gamblers, demonstrating the heterogeneity of Internet gamblers. Problem gambling respondents were younger, less educated, had higher household debt, lost more money and gambled on a greater number of activities, and were more likely to use drugs while gambling as compared to non-problem and at-risk gamblers. For problem gamblers, Internet gambling poses unique problems related to electronic payment and constant availability leading to disrupted sleeping and eating patterns.

This paper presented analyses based on the 2010 British Gambling Prevalence Survey examining the integration of online and offline gambling, including gamblers that use both modes. This was one of the first papers to highlight that there are very few pure Internet-only gamblers and gambling problems appeared to be highest among those who were more involved in a variety of forms.

Addict Behav. 2015;41:34–40. Based on a large online survey, participants were compared based on their use of Internet, as well as land-based gambling. Results demonstrate that gamblers using both Internet and land-based modes had the greatest overall involvement in gambling and greatest level of gambling problems. This study confirms the importance of considering gambling involvement across subgroups of Internet or land-based gamblers. [PubMed]

This paper reports the results of a large online survey in the UK using latent class analyses to identify subgroups of gamblers based on their use of the Internet to gamble. This was one of the first papers to move away from the dichotomy of Internet vs. non-Internet gamblers and made a significant contribution by showing that more involved gamblers had highest clusters of gambling problems and that Internet gamblers are a heterogeneous group.

This paper includes the innovative methodology of a self-report screen with behavioural data. Analysing gambling across different types of activities, this paper demonstrates that the extent of overall involvement (types of games and days played) is related to gambling problems.

Content Type: White Paper
Topics: Internet Gambling
While Internet gambling isn’t legal in all parts of the U.S., it is a growing form of gambling around the world and this often leads to speculation that its level of accessibility makes it more addictive than other types of gambling. The NCRG’s white paper, titled “Internet Gambling: An Emerging Field of Research,” provides the latest empirical, peer-reviewed research on Internet gambling to help address many questions that have been raised as U.S. federal and state government officials debate the legalization of online gambling.
This white paper includes the most reliable research available on online gambling; it also summarizes the findings of Harvard Medical School Professor Howard J. Shaffer, Ph.D., and colleagues, on this topic. It also contains research on online poker, sports betting and casino games, and includes information on online gambling among college students. Additionally, it suggests how the research can be used to develop responsible gaming strategies.
