Individuals with schizophrenia are over three times more likely to have problem and pathological gambling (PPG) than the general population (Cunningham-Williams et al., 1998; Desai and Potenza, 2009), but little is known about this co-occurrence and how PPG relates to specific symptom dimensions of psychotic disorders. Although cognitive distortions in PPG have been linked to gambling motivations (e.g., distorted thoughts about odds of winning), how psychotic symptoms in schizophrenia or related disorders relate to gambling motivations have not been examined systematically to date. Individuals with schizophrenia or schizoaffective disorder (n = 170) completed structured face-to-face interviews regarding problem-gambling severity, gambling motivations, and five symptom factors of psychosis (Positive, Negative, Disorganized/Concrete, Depressed, and Excited). Different symptom dimensions of psychosis showed distinct patterns of relationships with motivations to gamble and gambling onset. PPG in schizophrenia was associated with elevated scores on the Depressed factor. Psychotic symptom severity was associated with increased motivation to gamble for financial reasons and decreased motivations to gamble for service, and possibly social or interpersonal, reasons. Age of gambling onset was inversely associated with psychotic symptom severity, particularly positive features. Our findings suggest that motivations for gambling may differ in the context of schizophrenia and relate to specific symptom clusters.
