Impact of sociodemographic and clinical factors on subjective quality of life in schizophrenia patients in Beijing, China.

The impact of sociodemographic and clinical factors on subjective quality of life (SQOL) in Chinese schizophrenia outpatients was explored. Randomly selected subjects with schizophrenia (N = 273) were assessed with respect to their sociodemographic, clinical characteristics, and SQOL. Compared with the Chinese general population, patients had significantly lower scores in the physical and social SQOL domains. Multiple regression analyses revealed that depressive symptoms inversely predicted all SQOL domains; positive symptoms negatively predicted psychological, social, and environmental SQOL domains whereas educational level, extrapyramidal side effects, anxiety, history of suicide attempts, employment status, monthly income, number of hospitalization, and length of illness all significantly contributed to 1 or 2 SQOL domains.
