Abstract

OBJECTIVES
Quality of life in patients with psychotic disorders and their caregivers has a important role on the treatment and relapse prevention of the patients. This study was intended to investigate the effects of patient's sociodemographic, clinical and psychological(self-esteem, social support and external control) characteristics, and caregivers' sociodemographic and psychological characteristics on quality of life in patients and caregivers.
METHODS
The subjects were composed of 48 out-patients (schizophrenic disorder, mood disorders and other psychotic disorders) and 48 caregivers. Patients' clinical characteristics, patients' and their caregivers' sociodemographic, psychological characteristics(self-esteem, social support and external control) and quality of life were investigated. First of all, patients' self-esteem, social support, external control and quality of life were compared with caregivers'. After the correlations among each characteristics in patients and caregivers were calculated, the multiple regression analyses were conducted, where the predictable variables were those that had already shown significant correlations with quality of life.
RESULTS
Patients' self-esteem and quality of life were significantly lower than their caregivers'. In patients, high socioeconomic status and self-esteem were correlated with high perception on the social support and quality of life. Also, the satisfaction to the medication was positively correlated with perception on the social support, quality of life and more external control. In addition, high compliance on medication and high perception on the social support were correlated with high quality of life. In caregivers, patients' onset age was positively correlated with caregivers' quality of life. Also, more caregivers' stress was correlated with their lower self-esteem, and higher caregivers' self-esteem was correlated with higher perception on the social support and quality of life. Furthermore, higher caregivers' perception on the social support was correlated with higher quality of life. The characteristics that predicted patients' quality of life significantly were self-esteem and perception on the social support, and the characteristics that predicted caregivers' quality of life significantly were caregivers' perception on the social support and patients' onset age.
CONCLUSION
These results suggested that for improving the quality of life of patients and their caregivers, it was important not only to alleviate and treat the patient's symptom, but also to increase self-esteem and provide social support.
