Differences between heroin and nonheroin users were determined at intake and discharge from an inpatient rehabilitation program. Background data as well as attitudes toward drug-related concepts, mood, and symptoms were gathered from 65 male veterans. Data were analyzed by analysis of variance and covariance comparing heroin and nonheroin users at intake and discharge. There were no significant differences between these two groups on their prescores, indicating that heroin and nonheroin patients were quite similar at time of intake. However, at discharge significant differences were found in terms of Tense and Thoughtful from the Mood Scale and Somatization, Obsessive/Compulsiveness, Interpersonal Sensitivity, Depression, and Anxiety from the Symptom Checklist. The heroin subjects had consistently more positive rating than the nonheroin subjects following treatment.
