Correlations between Psychiatric Symptoms and Quality of Life in Patients with Psychological Disorders: Hospital-Based Retrospective Study

Abstract

Little research has been conducted on the relationship between the five-item Brief Symptom Rating Scale (BSRS-5) and quality of life in patients with mood disorders. The purpose of this study was to investigate potential effects of psychological symptoms on quality of life in patients with psychological disorders. We recruited 124 patients with psychological disorders from a psychological teaching hospital in northern Taiwan. Data were obtained from medical records of all patients with a diagnosis of mood or adjustment disorder. We assessed psychological symptoms on the BSRS-5 and examined quality of life by using the Taiwanese version of the abbreviated World Health Organization Quality of Life Questionnaire (WHOQOL-BREF). We performed hierarchical linear regression analysis to explore the relationship between psychological symptoms and quality of life. The analysis revealed a significant correlation between the items on the BSRS-5 and WHOQOL and their correlations with the total scores on these assessments (p < 0.01 and p < 0.05). Our findings indicated that scores on the BSRS-5 can predict scores on quality of life. This suggests that psychometrically measured psychological symptoms constitute critical determinants of quality of life.
