Where Do Gambling Problems Fit in the Structure of Psychopathology During Emerging Adulthood?

What is known about population level programs designed to address gambling-related harm: rapid review of the evidence

BACKGROUND

Gambling and gambling-related harm attract significant researcher and policy attention. The liberalisation of gambling in most western countries is strongly associated with a marked rise in gambling activity and increases in gambling-related harm experienced at the population level. Programs to address gambling-related harm have traditionally focused on individuals who demonstrate problematic gambling behaviour, despite clear evidence of the effectiveness of a public health approach to high-risk activities like gambling. Little is known about the availability or efficacy of programs to address gambling-related harm at a population level.

METHODS

The Victorian Responsible Gambling Foundation commissioned a rapid evidence review of the available evidence on programs designed to reduce gambling-related harm at a population level. The review was conducted using a public health and harm reduction lens. MEDLINE, ProQuest Central and PsychInfo databases were searched systematically. Included studies were published in English between 2017 - 2023 from all countries with gambling policy contexts and public health systems comparable to Australia's; included primary data; and focused on primary and/or secondary prevention of gambling-related harm or problems.

RESULTS

One hundred and sixty-seven articles were eligible for inclusion. Themes identified in the literature included: risk and protective factors; primary prevention; secondary prevention; tertiary prevention; target population group; and public health approach. The evidence review revealed a gap in empirical evidence around effective interventions to reduce gambling-related harm at the population level, particularly from a public health perspective.

CONCLUSIONS

Addressing gambling-related harm requires a nuanced, multi-layered approach that acknowledges the complex social, environmental, and commercial nature of gambling and associated harms. Moreover, evidence demonstrates community programs to reduce gambling-related harm are more successful in reducing harm when based on sound theory of co-design and address the social aspects that contribute to harm.

Alternative hypotheses regarding the association between early engagement in gambling and gambling-like activities and later problem gambling - a commentary on Richard and King (2023)

This issue of the Journal of Child Psychology and Psychiatry includes a systematic review on the emergence of problem gambling from childhood to emerging adulthood (Richard & King, 2023). The importance of understanding the risks for problem gambling earlier in development is clear, given the increasing availability of gambling to minors, especially online gambling.

Validity and utility of Hierarchical Taxonomy of Psychopathology (HiTOP): III. Emotional dysfunction superspectrum

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a quantitative nosological system that addresses shortcomings of traditional mental disorder diagnoses, including arbitrary boundaries between psychopathology and normality, frequent disorder co-occurrence, substantial heterogeneity within disorders, and diagnostic unreliability over time and across clinicians. This paper reviews evidence on the validity and utility of the internalizing and somatoform spectra of HiTOP, which together provide support for an emotional dysfunction superspectrum. These spectra are composed of homogeneous symptom and maladaptive trait dimensions currently subsumed within multiple diagnostic classes, including depressive, anxiety, trauma-related, eating, bipolar, and somatic symptom disorders, as well as sexual dysfunction and aspects of personality disorders. Dimensions falling within the emotional dysfunction superspectrum are broadly linked to individual differences in negative affect/neuroticism. Extensive evidence establishes that dimensions falling within the superspectrum share genetic diatheses, environmental risk factors, cognitive and affective difficulties, neural substrates and biomarkers, childhood temperamental antecedents, and treatment response. The structure of these validators mirrors the quantitative structure of the superspectrum, with some correlates more specific to internalizing or somatoform conditions, and others common to both, thereby underlining the hierarchical structure of the domain. Compared to traditional diagnoses, the internalizing and somatoform spectra demonstrated substantially improved utility: greater reliability, larger explanatory and predictive power, and greater clinical applicability. Validated measures are currently available to implement the HiTOP system in practice, which can make diagnostic classification more useful, both in research and in the clinic.

Association patterns of cannabis abuse and dependence with risk of problematic non-substance-related dysregulated and addictive behaviors

Co-occurrence of drug misuse with other dysregulated behaviors is common. This study was aimed at exploring the associations between the risk of presenting a clinically relevant condition involving non-substance-related addictive or dysregulated behaviors (as measured by the MultiCAGE CAD-4 screening), and cannabis abuse/dependence (CAST/SDS) scores, and the role of gender therein. Participants were recruited using stratified probabilistic sampling at the University of Granada. Mann-Whitney’s U tests were used to compare male and female students in SDS and CAST scores. Associations between gender and MultiCAGE scores were estimated using the γ ordinal correlation index, and tested with χ². For each MultiCAGE dimension, a Poisson-family mixed-effects model was built with either SDS or CAST as the main input variable, while controlling for nicotine and alcohol dependence, and relevant sociodemographic variables. Incidence rate ratios (IRR) were computed for SDS/CAST effects, and the significance threshold was family-wise Bonferroni-corrected. Gender differences were significant for cannabis dependence/abuse and all MultiCAGE scores for non-substance-related conditions, with males showing higher risk scores for excessive gambling, excessive internet use, excessive video gaming, and hypersexuality, and females presenting higher scores in dysregulated eating and compulsive buying. Cannabis dependence and abuse were significantly associated with a higher risk of problematic video gaming. These associations were mostly driven by males. Importantly, although risk of problematic video gaming was specifically associated with cannabis abuse/dependence, there was only a weak non-significant association between problematic video gaming and alcohol use scores. Risk of alcohol use problems, in turn, was strongly associated with all other non-substance-related problems (problematic gambling, excessive Internet use, dysregulated eating, compulsive buying, and hypersexuality). These differential associations can cast light on the etiological similarities and dissimilarities between problematic substance use and putative addictive behaviors not involving drugs.
