Abstract

This study investigated whether or not the effects of long-term hospitalization among patients with schizophrenia on their social functioning such as daily life activities, interpersonal relationships, employment, and so on would create negative symptoms such as anhedonia, asociality, avolition, blunted affect, and alogia. The sample was comprised of 51 participants. The dependent variable was one item in the Life Assessment Scale for the Mentally Ill, and the independent variables were subdomains of the Brief Negative Symptom Scale. The items were analyzed with Spearman's rank correlation coefficient and subsequently entered in a multiple regression analysis. Results showed that daily life activities and work contribution significantly predicted avolition. Furthermore, interpersonal relationships significantly predicted asociality and blunted affect. Self-recognition was not associated with any factor. For managing the negative symptoms of schizophrenia, relief efforts must focus on discharge support, avolition, asociality, and blunted affect.
