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.
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).
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.
These findings encourage the continued use and evaluation of the CDS for measuring symptoms of depressive affect in cardiac patients.
开展本研究以提供进一步证据，支持心脏抑郁量表（CDS）在心血管疾病患者群体中的可靠性和有效性。
对627名连续参加门诊心脏康复项目的成年心脏门诊患者施测CDS，一个亚组还完成了老年抑郁量表简表（GDS-SF）。
因子分析揭示了六个子量表，占量表方差的62%。CDS表现出较高的内部一致性（克朗巴哈系数α = 0.92），与GDS-SF的相关系数为0.77。受试者工作特征曲线表明，CDS的临界值为100时可检测出更严重的抑郁，临界值为90时可检测出轻至中度抑郁。
这些发现鼓励继续使用和评估CDS来测量心脏病患者的抑郁情绪症状。
