A community study of the health-related quality of life of schizophrenia and general practice outpatients in Singapore

Abstract

Background: Health-related quality of life (HRQOL) is an important outcome indicator of healthcare that has been little studied in East Asia, where, culturally, there is greater family interdependence than in the West. We aimed to study the HRQOL of schizophrenia outpatients compared to general practice outpatients, and to examine determinants of schizophrenia HRQOL in our community.

Methods: The HRQOL of 94 schizophrenia and 90 general practice outpatients was assessed using the COOP/WONCA chart. Clinical status, demographics, medication dosages, extrapyramidal side-effects, and frequency of personal, family and social functioning were assessed using standardized questionnaires.

Results: Some 90% of schizophrenia outpatients still lived with their immediate families, and the majority were single, unemployed, and rarely engaged in social activities. They had poorer satisfaction with overall HRQOL compared to general practice outpatients. Using stepwise linear regression analysis, poorer schizophrenia overall HRQOL was predicted by dissatisfaction with and poorer participation in family relationships, dissatisfaction with emotional well-being and male gender [R(2) = 0.40, p = 0.040; F(4, 5.1) = 14.3, p < 0.001].

Conclusions: Strained family relationships appeared to be an important contributor to poorer schizophrenia HRQOL in our East Asian community. This could possibly be related to the narrowing of social-occupational functioning and its burden on the family.
