Moderating Effect of Impulsivity on the Association Between Entrapment and Problem Gambling

Mediating Role of Impulsivity in the Contributory Roles of Upward Versus Downward Counterfactual Thinking in Youth Gambling Intention

The proliferation of gambling shops, and the growing gambling prevalence in Nigeria, youths have constantly engaged in gambling activities even during school period. This has raised concerns among therapists and parents as the trend could degenerate to problem gambling and its associated psychosocial problems if left unchecked. Our study examined the role of impulsivity as a mediator in the association between two types of counterfactual thinking (CFT) and gambling intention in a non-clinical sample. A self-report measure containing South Oaks Gambling Screen: Reversed for Adolescents (SOGS: RA), CFT, and impulsivity scales was completed by 371 Nigerian adolescents who had gambled for money (mean age = 17.37 years; SD = 4.13). After controlling for age, increase in downward CFT was associated with decreased gambling intention, whereas increase in upward CFT and impulsivity were associated with increased gambling intention. Upward CFT contributed more to gambling intention than downward CFT. Mediation result showed that Impulsivity significantly mediated only the association between upward CFT and gambling intention. We concluded that gambling therapies should include treatment packages that enhance impulse control abilities and gambling-related downward CFT and at the same time, attenuate gambling-related upward CFT.

Gambling in Sub-Saharan Africa: Traditional Forms and Emerging Technologies

Purpose of Review

The gambling industry in Africa has seen substantial growth and evolution over recent years with a growing body of literature describing these shifts. Here, we provide a narrative synthesis of the extant literature on the origins, trends and consequences of the expansion and intensification of the commercial gambling industry in sub-Saharan Africa with a reference for future research on gambling as a growing public health concern.

Recent Findings

The historical shift and permeation of gambling in sub-Saharan Africa is diverse with evidence of certain countries following a neo-colonial logic. Advances in technology have made gambling more accessible and created new markets in Africa. A key motive driving gambling on the continent is a lack of stable employment. While the intensification and growth of Africa’s gambling industry has brought economic benefits to some African investors and individuals, this has been accompanied by a range of gambling harms. Legislation and policies designed to better regulate the gambling industry and redress these harms are needed. In this context, a small number of services and campaigns designed to mitigate gambling harms demonstrate promise, but more research is needed in this area.

Summary

The gambling industry in sub-Saharan Africa has undergone a dramatic transformation. While it is true that the growth of the African gambling industry has provided an additional revenue stream to governments, it is also necessary to acknowledge the concurrent rise in gambling addiction and the health-related and social harms that it elicits. As such, designing effective regulatory measures and policy interventions that can reduce the public health burden of gambling harms is vital. However, these interventions need to take in to account the significance of cultural differences that exist among countries on the continent.

Delay Discounting in Established and Proposed Behavioral Addictions: A Systematic Review and Meta-Analysis

Steep delay discounting, or a greater preference for smaller-immediate rewards over larger-delayed rewards, is a common phenomenon across a range of substance use and psychiatric disorders. Non-substance behavioral addictions (e.g., gambling disorder, internet gaming disorder, food addiction) are of increasing interest in delay discounting research. Individual studies have reported steeper discounting in people exhibiting various behavioral addictions compared to controls or significant correlations between discounting and behavioral addiction scales; however, not all studies have found significant effects. To synthesize the published research in this area and identify priorities for future research, we conducted a pre-registered systematic review and meta-analysis (following PRISMA guidelines) of delay discounting studies across a range of behavioral addiction categories. The final sample included 78 studies, yielding 87 effect sizes for the meta-analysis. For studies with categorical designs, we found statistically significant, medium-to-large effect sizes for gambling disorder (Cohen’s d = 0.82) and IGD (d = 0.89), although the IGD effect size was disproportionately influenced by a single study (adjusted d = 0.53 after removal). Categorical internet/smartphone studies were non-significant (d = 0.16, p = 0.06). Aggregate correlations in dimensional studies were statistically significant, but generally small magnitude for gambling (r = 0.22), internet/smartphone (r = 0.13) and food addiction (r = 0.12). Heterogeneity statistics suggested substantial variability across studies, and publication bias indices indicated moderate impact of unpublished or small sample studies. These findings generally suggest that some behavioral addictions are associated with steeper discounting, with the most robust evidence for gambling disorder. Importantly, this review also highlighted several categories with notably smaller effect sizes or categories with too few studies to be included (e.g., compulsive buying, exercise addiction). Further research on delay discounting in behavioral addictions is warranted, particularly for categories with relatively few studies.

Moderating Effects of Herding Bias on the Relationship Between Parental Monitoring and Problem Gambling of Youths

One critical issue in problem gambling is its variation as a function of psychosocial factors. We used empirical data from Nigerian youth Soccer gamblers (N = 238) to explore gambling herding bias as a moderator of the relationship between parental monitoring and problem gambling. Specifically, examine how changes in parental monitoring influence changes in problem gambling, and how this influence is a function of levels of herding bias. Hayes PROCESS macro analysis results revealed that increase in parental monitoring was associated with decrease in problem gambling, whereas increase in herding bias was associated with increase in problem gambling. Herding bias positively moderated the relationship between parental monitoring and problem gambling such that, for respondents who had high and moderate herding bias scores, the relationship between parental monitoring and problem gambling was positive and strong, whereas, for repondents with low herding bias scores, the relationship between parental monitoring and problem gambling was negative. The present study reaffirms the negative and positive influences of parental monitoring and herding bias, respectively, on problem gambling among youths.
