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

Psychiatric disorders frequently co-occur with gambling disorder. Although community and clinical samples show frequent co-occurrence between gambling and psychotic disorders, relatively little research has been conducted on this population. Here, we comment on a recent study conducted in Brazil on the clinical correlates of psychotic disorders in treatment-seeking individuals with gambling disorder, relate the findings to those from the northeastern region of the United States, and discuss implications with respect to promoting responsible gambling in the setting of the expansion of legalized gambling.
