Some authors have also hypothesized a causal relationship in the comorbidity of depression and gambling, by investigating the time course of the two disorders ( Chou & Afifi, 2011 Dussault et al., 2016). ( 2010) reported a 9.4% prevalence rate of problem gambling and in another study, Quilty, Watson, Robinson, Toneatto, and Bagby ( 2011) found a rate of 12.5%. Another relevant paper is the Epidemiologic Catchment Area study ( McIntyre et al., 2007) that found a 13.3% rate of problem gambling in individuals with bipolar disorder.Īs for unipolar depressive patients, Kennedy et al. As far as any psychotic illness, only one study was published on patients with schizophrenia, bipolar illness, depressive psychosis, and schizoaffective disorder, reporting a risk of problem gambling four times higher in patients than the general population ( Haydok et al., 2015).Īs far as bipolar illness, a mailing survey of the Bipolar Disorder Research Network ( Jones et al., 2015) on 750 participants, with a 23% completion rate, found a 10.6% overall rate of problem gambling, whereas severe risk was 2.7%. The first published study on gambling behavior in outpatients with schizophrenia was conducted by Desai and Potenza ( 2009) and reported a 19% prevalence rate. Research on the comorbidity of gambling problems with other psychiatric diagnoses has mainly focused on the comorbidity of gambling and substance-use problems ( Bonnaire et al., 2017 Rodriguez-Monguio, Errea, & Volberg, 2017 Wareham & Potenza, 2010), whereas the comorbidity in patients with major psychiatric illness has been less investigated.
