Abstract:
Objective:More attempts have been made recently to improve psychosocial functioning and quality of life in patients with schizophrenia, due to their crucial role in long-term outcomes. Previous studies on the effects of clozapine on psychosocial functioning have been limited in terms of generalizability and application to clinical practice. This study examined the relationship of clozapine use with psychosocial functioning and quality of life in patients with schizophrenia in a real-world setting.
Methods:Data were obtained from a survey targeting community-dwelling patients with schizophrenia. The Behavior and Symptom Identification Scale (BASIS) and Satisfaction with Life Scale (SWLS) were administered to evaluate psychosocial functioning and quality of life, and patients were classified into Clozapine and Non-clozapine groups. Group differences were assessed using ANCOVA, with additional sensitivity analyses for participants on atypical antipsychotic medications only.
Results:Of 292 patients, the Clozapine group (n=34) had significantly better psychosocial functioning and quality of life than the Nonclozapine group (n=258), as demonstrated by their low BASIS score (F=4.651, df=1, 290, p=0.032) and high SWLS score (F=14.637, df=1, 290, p<0.001). Similar findings for psychosocial outcomes were observed in the analyses of the atypical antipsychotic subgroup (n=195).
Conclusion:For optimal recovery in schizophrenia, restoration of impaired social functioning and enhanced satisfaction with life are essential. In this study, clozapine use was related to high levels of psychosocial functioning and quality of life in real-world settings. Further research on the causal relationship between clozapine use and psychosocial functioning is needed.
