Effectiveness of clozapine and a social learning program for severely disabled psychiatric inpatients.

Abstract

This study examined the combined effectiveness of clozapine and a comprehensive inpatient psychosocial rehabilitation program on the clinical functioning and aggressive behaviors of patients with chronic schizophrenia. Two groups of 11 subjects each were selected from among patients being treated in the social learning program at Fulton (Mo.) State Hospital. Group 1 subjects were placed on clozapine at various times after the introduction of the program, while group 2 subjects remained on traditional antipsychotics throughout the study period. Group 1 and group 2 subjects were matched on clinical functioning as measured by the Time-Sample Behavioral Checklist (TSBC). For each subject, scores on six TSBC subscales were examined at five time points. Data were analyzed using repeated-measures multiple analysis of variance and univariate analyses of variance. Data on frequency of aggressive behaviors were aggregated into three six-month time periods and were analyzed using Wilcoxon signed-rank tests. Both groups demonstrated significant improvement on several measures. However, the addition of clozapine resulted in accelerated improvement for group 1 subjects, especially in aggressive behaviors. Comprehensive psychosocial treatment programming resulted in significant improvements in clinical functioning for many inpatients. Clozapine may enhance responsiveness to such programming for some patients.
