Problem gambling in psychotic disorders: A systematic review and meta‐analysis of prevalence

Abstract

IntroductionProblem gambling (PBG) is more common in people with mental health disorders, including substance use, bipolar, and personality disorders, than in the general population. Although individuals with psychotic disorders might be expected to be more vulnerable to PBG, fewer studies have focused on this comorbidity. The aim of this review was to estimate the prevalence of PBG in people with psychotic disorders.MethodsMedline (Ovid), EMBASE, PsycINFO (Ovid), CINAHL, CENTRAL, Web of science, and ProQuest were searched on November 1, 2023, without language restrictions. Observational and experimental studies including individuals with psychotic disorders and reporting the prevalence of PBG were included. Risk of bias was assessed using the Joanna Briggs Institute critical appraisal for systematic reviews of prevalence data. The pooled prevalence of PBG was calculated using a fixed effects generalized linear mixed model and presented through forest plots.ResultsOf 1271 records screened, 12 studies (n = 3443) were included. The overall prevalence of PBG was 8.7% (95% CI = 7.8%–9.7%, I2 = 69%). A lower prevalence was found in studies with a low risk of bias (5.6%; 95% CI = 4.4%–7.0%) compared with studies with a moderate risk of bias (10.4%; 95% CI = 9.2%–11.7%). Different methods used to assess PBG also contributed to the heterogeneity found.ConclusionThis meta‐analysis found substantial heterogeneity, partly due to the risk of bias of the included studies and a lack of uniformity in PBG assessment. Although more research is needed to identify those at increased risk for PBG, its relatively high prevalence warrants routine screening for gambling in clinical practice.

A Study of the Psychometric Properties of the Persian Version of the Online Gambling Symptom Assessment Scale in the Iranian Population

“…The results of studies show that the rate of major depression and dysthymia, as well as generalized anxiety, phobia, and panic, in pathological gamblers is 3 times higher than in non-gamblers. Pathological gamblers report more other problems such as job dismissal, divorce, mental problems, poor public health, and bankruptcy, 5 , 6 and even people who gamble recreationally have a high rate of abuse; they report dependence on alcohol and drugs, depression, and even imprisonment. 7 …”
