Quantitative scale validation of the Dimensional Anhedonia Rating Scale in the treatment of Chinese patients with major depressive disorder.

ABSTRACT:

Background

The patient-reported Dimensional Anhedonia Rating Scale (DARS) has been adapted into Chinese, so there is a need to evaluate its measurement properties in a Chinese population.

Aims

To evaluate the reliability and validity of the DARS among Chinese individuals with major depressive disorder (MDD) and its treatment sensitivity in a prospective clinical study.

Methods

Data were from a multicentre, prospective clinical study (NCT03294525), which recruited both patients with MDD, who were followed for 8 weeks, and healthy controls (HCs), assessed at baseline only. The analysis included confirmatory factor analysis, validity and sensitivity to change.

Results

Patients' mean (standard deviation (SD)) age was 34.8 (11.0) years, with 68.7% being female. 75.2
