Pattern of substance abuse in psychiatric inpatients.

This study examined the pattern of substance abuse in a sample of 114 psychiatric inpatients using a standardized diagnostic interview. As predicted, psychiatric inpatients reported a significantly higher rate of substance abuse than a randomly selected community sample. Approximately three-quarters of the inpatients abused at least one substance. Almost one-half of the patient sample reported abusing more than one substance. These findings emphasize the need to screen psychiatric inpatients for substance abuse using a standardized diagnostic instrument and to develop treatment programs for substance abuse in psychiatric patients.
