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.

Summary
The prevalence of psychological disorders increased by 13% between 2007 and 2017, mainly because of demographic changes. Mood disorders cost the global economy US$1 trillion each year [1]. Common mood disorders include non-psychotic, depressive, and anxiety disorders. Psychological disorders increase the risk of both communicable and noncommunicable diseases, which lead to unintended injury [3]. Psychological disorders rank first in the global burden of disease, equivalent to the combined burden of cardiovascular and circulatory diseases. Severe psychological diseases can trigger a cascade of socioeconomic and lifestyle changes that, in turn, can lead to adverse physical health effects and increase mortality risk to approximately two to three times that of the average person [6]. The examination of both social and psychological measures is essential [4]
