OBJECTIVE: The current study was undertaken to provide further evidence supporting the reliability and validity of the Cardiac Depression Scale (CDS) in a population of cardiovascular patients. METHODS: The CDS was administered to 627 consecutive ambulatory adult cardiac patients attending an outpatient Cardiac Rehabilitation program, and a subgroup also completed the Geriatric Depression Scale--Short Form (GDS-SF). RESULTS: Factor analysis revealed six subscales accounting for 62% of scale variance. The CDS demonstrated high internal consistency (Cronbach's alpha=.92) and correlation coefficient with the GDS-SF of .77. Receiver operating characteristic curves suggested a CDS cutoff score of 100 to detect more severe depression, and 90 to detect mild to moderate depression. CONCLUSION: These findings encourage the continued use and evaluation of the CDS for measuring symptoms of depressive affect in cardiac patients.
