To evaluate the validity and reliability of the Chinese version of the Short-Form Cardiac Depression Scale (CDS) as a screening tool.
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.
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 high correlations between the Chinese versions of the Short- Form CDS and the CDS (r = 0.80, P< 0.0001) and the Beck Depression Inventory (r = 0.64, P < 0.0001). Principal components analysis revealed a single dimension extracted from the data set, which resembles that reported by the authors of the original scale.
The Chinese Short-Form CDS appears to be a valid and reliable user-friendly measure for monitoring depressed mood in Chinese-speaking patients with cardiac disease.
评估短式心脏抑郁量表（CDS）中文版作为一种筛查工具的有效性和可靠性。
对 239 名中国心脏患者进行了测量性能测试，要求他们完成短式 CDS 中文版、CDS、贝克抑郁量表和整体情绪状态（单项）的中文版。
中国短式 CDS 表现出可接受的内部一致性（Cronbach's α 0.76）。五个项目与总量表之间的高相关系数（r = 0.63-0.74，P < 0.01）提供了进一步的内部一致性证据。与 CDS（r = 0.80，P< 0.0001）和贝克抑郁量表（r = 0.64，P < 0.0001）的中文版之间存在可接受的同时有效性，存在显著的高相关性。主成分分析从数据集提取了一个单一维度，与原始量表作者报告的维度相似。
中国短式 CDS 似乎是一种有效且可靠的、用户友好的测量工具，可用于监测患有心脏疾病的中文患者的抑郁情绪。
