Affect dimensions of male heroin addicts admitted for inpatient detoxification.

The Profile of Mood States was administered to 197 male heroin addicts seeking inpatient detoxification. A principal factor analysis of the men's self-ratings revealed four major dimensions-Fatigue-inertia, Confused-depression, Anger-hostility, and Friendliness; these dimensions were similar to factors reported for male psychiatric patients, but only the dimensions of Fatigue-inertia, Confused-depression, and Anger-hostility matched comparable factors reported for male heroin addicts seeking methadone maintenance. Fatigue-inertia was the major dimension underlying the inpatient admissions' affect, whereas Anger-hostility was the major dimension underlying the methadone admissions' affect.
