Functional Independence Measureを用いて評価した統合失調症入院患者の基本的な社会生活機能と臨床諸要因との関連

Objective : The aim of the present study is to explore clinical factors associated with basic ability of social life in schizophrenia inpatients. Methods : The subjects were 50 inpatients with schizophrenia (DSM‐IV). Their mean age was 53.08 (SD＝12.08） years. Social life functioning was evaluated using the Functional Independence Measure (FIM). Cognitive function was assessed with the Brief Assessment of Cognition in Schizophrenia (BACS) and clinical symptoms with the Positive and Negative Syndrome Scale (PANSS), the Calgary Depression Scale for Schizophrenia (CDSS) and the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS). Results : FIM motor subscale score showed a significant correlation with the DIEPSS score (r＝0.33, p＜0.05). The FIM cognitive subscale score showed significant correlations with the PANSS positive syndrome score (r＝－0.30, p＜0.05), the PANSS negative syndrome score (r＝－0.37, p＜0.01） and the DIEPSS score (r＝－0.40, p＜0.01）. Conclusion : These results suggest that positive and negative symptoms and drug-induced extrapyramidal symptoms are much more important factors related to lowered basic ability of social life of schizophrenia inpatients than cognitive function.
