This study examined the psychometric properties of the Cardiac Depression Scale (CDS) in a sample of coronary heart disease (CHD) patients.
A total of 152 patients were diagnosed with coronary heart disease and were administered the CDS along with the Beck Depression Inventory- 2 (BDI-2) and the State Trait Anxiety Inventory (STAI) 3.5-months after cardiac hospitalization.
The CDS's factorial composition in the current sample was similar to that observed in the original scale. Varimax-rotated principal-components analyses extracted six factors, corresponding to mood, anhedonia, cognition, fear, sleep and suicide. Reliability analyses yielded internal consistency α - coefficients for the six subscales ranging from 0.62 to 0.82. The CDS showed strong concurrent validity with the BDI-II (r = 0.64). More patients were classified as severely depressed using the CDS. Both the CDS and the BDI-2 displayed significantly strong correlations with the STAI (r = 0.61 and r = 0.64), respectively.
These findings encourage the use of the CDS for measuring the range of depressive symptoms in those with CHD 3.5 months after cardiac hospitalization.
本研究在冠心病患者样本中检验了心脏抑郁量表（CDS）的心理计量学特性。
共有 152 名被诊断为冠心病的患者在心脏住院 3.5 个月后接受了 CDS 以及贝克抑郁量表第二版（BDI-2）和状态特质焦虑量表 3.5（STAI 3.5）的评估。
当前样本中 CDS 的因子构成与原始量表中观察到的相似。方差极大旋转主成分分析提取了六个因子，分别对应于情绪、快感缺失、认知、恐惧、睡眠和自杀。六个分量表的内部一致性 α 系数为 0.62 至 0.82。CDS 与 BDI-II 具有很强的同时效度（r=0.64）。使用 CDS 对更多的患者进行了重度抑郁的分类。CDS 和 BDI-2 与 STAI 均呈显著的强相关性（r=0.61 和 r=0.64）。
这些发现鼓励在心脏住院 3.5 个月后使用 CDS 测量冠心病患者抑郁症状的范围。
