Are Comorbid Disorders Associated with Changes in Gambling Activity? A Longitudinal Study of Younger and Older Subjects with DSM-IV Pathological Gambling

A 5-year longitudinal examination of the co-occurring patterns of gambling and other addictive behaviors

OBJECTIVE

We examined the co-occurring patterns of problem gambling and substance/behavioral addiction severity over a five-year period and the predictors of the different co-occurring patterns of problem gambling and addiction severity.

METHODS

We conducted a secondary analysis of the Quinte Longitudinal Study (QLS) data. The QLS is a 5-year prospective longitudinal study of gambling and problem gambling in the Quinte Region in Southern Ontario. The QLS consists of a total of 4,121 participants, including a sample of participants at risk of developing problem gambling. Severity of problem gambling, substance use, and behavioral addictions were used to examine their co-occurring patterns over time. Predictors of the co-occurring patterns included the presence of mental health disorders, personality, stress, happiness, lifesatisfaction, social support, family history, and demographics.

RESULTS

Six co-occurring patterns of problem gambling and addiction severity were identified. The largest co-occurring pattern was characterized by concurrent decrease in gambling and other addictive behaviors. Several co-occurring patterns were characterized by moderate-to-severe problem gambling and other addiction severity that remained stable over time. No co-occurring pattern represented a decrease in gambling followed by increase in other addictive behaviors (e.g., addiction substitution). The presence of mental health disorders, stress, and lifesatisfaction significantly predicted the different co-occurring patterns.

CONCLUSIONS

Taken together, the results suggest that in a non-clinical sample, gambling and other co-occurring addictive behaviors are likely to simultaneously decrease over time. Comorbidity of mental health disorders significantly influences co-occurring patterns of gambling and other addictive behaviors.

Developmental Patterns of Gambling Participation and Substance use Throughout Adolescence in a Population Birth Cohort

This study investigated adolescents' single and co-occurring developmental patterns of gambling participation and substance use and their association with gambling and substance use-related issues at age 17, controlling for confounders. Multiple assessments from age 12 to 17 were conducted in a population-based cohort (N=1594, 51.2% boys). Latent growth modeling was used to analyze developmental patterns and Generalized linear models to examine their association with age-17 gambling and substance use-related problems, types and variety of activities, and substance abuse. Results revealed six developmental patterns, including Low- or Non-substance Users or Gamblers (24.2% sample), two trajectory-classes of Later-Onset Increasing (to a moderate level) substance users, either with or without gambling participation (7.8% and 45.5%, respectively), two trajectory-classes of Early-Onset Increasing (to a higher level) substance users, either with or without gambling participation (6.2% and 12.7%, respectively), and a smaller trajectory-class of Slow-Increasing Substance Users and Early-Onset Gamblers, declining to non-gambling after age 13 (3.6%). Gambling participation and substance use did not appear to influence each other with regard to their onset and course throughout adolescence, and to age-17 types and variety of gambling activities or substances used, problems related to gambling participation or substance use, or substance abuse. These findings are consistent with the addictive syndrome model and with both common and individualized approaches to prevention and treatment for adolescent gamblers or substance users.

Cross-Addiction Risk Profile Associations with COVID-19 Anxiety: a Preliminary Exploratory Study

"Cross-addiction" involves a person substituting one form of addictive behaviour for another. Indeed, cross-additive presentations have been frequently described (e.g. from drugs to alcohol, gambling to sex), and risk profiles have been assumed. Nevertheless, there has been a dearth of evidence considering the occurrence of cross-addiction risk profiles in the community. This research is imperative for informing effective prevention/intervention policies, especially under anxiety-provoking conditions, such as the current coronavirus pandemic. To address this need, a cross-sectional exploratory research design was utilized, with quantitative survey data obtained from 968 respondents (18-64; M age  = 29.5 years, SD = 9.36), who completed an online survey regarding a range of addictive behaviours (i.e. abuse of alcohol, drug, smoking, online gaming, shopping, internet, exercise, online gambling, sex, and social media) and their anxiety about the coronavirus. Latent class/profiling analyses were implemented to (a) explore profiles of cross-addiction risk, (b) describe the characteristics and the proportions of these profiles, and (c) identify their differential associations with the pandemic precipitated anxiety. Findings revealed two distinct profiles/types, the "cross-addiction low risk" (57.4%) and the "cross-addiction high risk" (42.6%). Those in the latter scored consistently higher across all behaviours assessed, were more likely to suffer from concurrent addictive problems, and reported significantly higher levels of pandemic-related anxiety. Implications for prevention, assessment, and treatment and future research are discussed.
