A Psychometric Evaluation of the Chinese Version of the Short-Form Cardiac Depression Scale

Abstract

Objective: To evaluate the validity and reliability of the Chinese version of the Short-Form Cardiac Depression Scale (CDS) as a screening tool. Methods: Measurement performance was tested on 239 Chinese cardiac patients who were asked to complete the Chinese versions of the Short-Form CDS, the CDS, the Beck Depression Inventory, and an overall measure (single item) of mood status. Results: The Chinese Short-Form CDS demonstrated acceptable internal consistency (Cronbach's α 0. 76). The high correlation coefficients (r = 0.63-0.74, P < 0.01) between the five items and the total scale provide further evidence of internal consistency. There was acceptable concurrent validity with significantly..
