Abstract: The aim of this study was to assess the associations between substance use disorders and temperamental characteristics in subjects with non-affective psychotic disorders or mood disorders. Consecutively hospitalized patients were interviewed with a structured diagnostic interview to define DSM-IV diagnoses, including those of substance use. Temperamental characteristics were measured using the Sensation-Seeking Scale (SSS), the Barratt Impulsivity Scale (BIS) and the Physical Anhedonia Scale. Inpatients (n = 103) with non-affective psychotic disorders (n = 45) or mood disorders (n = 58) were included. Among these patients, 25.2% presented with a lifetime (LT) history of alcohol abuse/dependence and 23.3% presented with a LT history of cannabis abuse/dependence. A LT history of alcohol misuse was independently associated with higher scores at the 'experience seeking' and 'disinhibition? subscales of the SSS. A LT history of cannabis misuse was independently associated with higher scores on the 'disinhibition' subscale of the SSS and the 'non-planning activity' subscale of the BIS. These results suggest that sensation-seeking and impulsivity are temperamental characteristics that may favor substance use in patients with psychotic or mood disorders, independently from categorical diagnoses.
