Relationship between quality of life and clinical factors in inpatients with schizophrenia.

OBJECTIVE

The purpose of this study was to clarify the relationship between quality of life (QOL) and clinical factors in inpatients with schizophrenia.

METHODS

Subjects were 50 hospitalized patients with schizophrenia. Their mean age was 56.48 (Standard Deviation=11.93) years. Japanese version of the schizophrenia Quality of Life Scale (JSQLS) and Subjective Well-being under Neuroleptic drug Treatment Short form, Japanese version (SWNS-J) were used to assess subjective QOL, and Mini Mental State Examination-Japanese was used to evaluate cognitive function. Japanese version of the Calgary Depression Scale for Schizophrenia (JCDSS), Brief Psychiatric Rating Scale, and Drug-Induced Extrapyramidal Symptoms Scale were used to assess depression severity, psychotic symptoms, and drug-induced extrapyramidal symptoms, respectively. Stepwise regression analyses were conducted to find factors influencing JSQLS and SWNS-J.

RESULTS

JCDSS was a predictor of two scales of JSQLS, and JCDSS also predicted SWNS-J Total and it's two subscales. However, other clinical factors were not related to JSQLS and SWNS-J.

CONCLUSION

The results indicate that treating depressive symptoms may lead to improvement of subjective QOL in inpatients with schizophrenia. J. Med. Invest. 69 : 80-85, February, 2022.
