Disordered gambling and psychosis: Prevalence and clinical correlates

Demographic, psychiatric, and personality correlates of adults seeking treatment for disordered gambling with a comorbid binge/purge type eating disorder

“…Contrary to our hypothesis, however, GD + BP participants did not report greater gambling problem severity, despite having gambled more days in the past month. This finding diverges with previous research that has found that other comorbid psychiatric disorders are associated with greater gambling problem severity (Cassetta et al, in press; Lister et al, ). That said, this finding could be attributable to low power, as gambling severity was no longer significant when Bonferroni correction was applied.…”

“…Measures for this study were chosen based on their potential clinical relevance. For example, people with a dual diagnosis of gambling and other psychiatric disorders have been found to present with greater psychological distress (i.e., comorbidities), greater severity of gambling‐related problems, and higher levels of impulsivity (Cassetta et al, in press; Lister, Milosevic, & Ledgerwood, ). The domain of temperament/impulsivity was assessed because previous research suggests that these constructs may be of particular importance in differentiating people with a dual diagnosis of gambling disorder and bulimia nervosa/binge‐eating disorder (Alvarez‐Moya et al, ; Claes et al, ; Jiménez‐Murcia et al, ).…”

Recommendations for increasing research on co-occurring serious mental illness and gambling problems

“…The previously mentioned research highlights relationships between psychosis and problem gambling (Cassetta et al., 2018; Haydock et al., 2015). Without further research into these relationships, it is difficult to ascertain risk factors among individuals with SMI.…”

“…A recent study from Brazil of treatment-seeking individuals with gambling problems reported on the significance of the co-occurrence of gambling disorder with psychotic disorders, corroborating and extending findings from studies in the United States of gambling problems in individuals with psychotic disorders and from studies in the United States of community samples. Recently, researchers (Cassetta, Kim, Hodgins, McGrath, & Tomfohr-Madsen, 2018) studied the presence of co-occurring psychotic disorders and found it was associated with increased likelihoods of specific psychiatric concerns, particularly agoraphobia and suicidality. As such, considering how best to prevent and treat problem gambling in individuals with psychotic disorders warrants additional investigation, particularly as among other vulnerable groups (e.g., individuals with co-occurring alcohol and mental health disorders), the presence of gambling problems has been associated with poorer mental health outcomes (Grant, Potenza, Kraus, & Petrakis, 2017).…”

“…Despite evidence indicating that SMI frequently co-occurs with problem gambling (Cassetta et al., 2018; Desai & Potenza, 2009) and that the co-occurrence may be associated with significant negative impacts (Yakovenko, Clark, Hodgins, & Goghari, 2016), there are limited available data, and increased research efforts could help fill existing knowledge gaps and improve current screening and treatment of gambling problems in individuals with SMI (Yakovenko et al, 2018). As shown in Table 1, we have outlined knowledge gaps related to problem gambling and SMI.…”
