Cardiac patients experience various somatic and psychosocial symptoms and stress is an important prognostic factor of cardiac rehabilitation. This study evaluated the psychometric properties of the 12-item Cardiac Distress Inventory - Short Form (CDI-SF) in the Chinese context.
A total of 227 patients with cardiac diseases were recruited in a specialist outpatient clinic in Hong Kong between Aug 2022 and July 2023. The participants completed the CDI-SF and validated measures on psychosocial functioning and quality of life. Exploratory factor analysis and partial correlation analysis were conducted to examine the factorial validity, reliability, and convergent validity of the CDI-SF with reference to validating measures.
The 1-factor model showed adequate model fit with excellent composite reliability (ω = .92) and substantial factor loadings (λ = .64 -.94, <.01). The CDI-SF factor was negatively associated with age ( = -.21, <.01) and showed positive and strong partial correlations ( = .59 -.69, <.01) with impact of event, depression, and burnout, and negative partial correlations ( = -.43 to -.54, <.01) with resilience and quality of life.
Our study provides the first results on the psychometric properties of the CDI-SF among cardiac patients in Hong Kong. The psychometric results support the CDI-SF as a precise, valid, and reliable measure of cardiac distress in the Chinese context.
心脏病患者会经历各种躯体和心理社会症状，压力是心脏康复的一个重要预后因素。本研究评估了中文版12项心脏困扰量表简表（CDI-SF）的心理测量特性。
2022年8月至2023年7月期间，在香港一家专科门诊招募了227名心脏病患者。参与者完成了CDI-SF以及关于心理社会功能和生活质量的验证性测量。进行探索性因素分析和偏相关分析，以参照验证性测量来检验CDI-SF的因素效度、信度和收敛效度。
单因素模型显示出良好的模型拟合，具有出色的组合信度（ω = 0.92）和显著的因素载荷（λ = 0.64 - 0.94，P < 0.01）。CDI-SF因素与年龄呈负相关（r = -0.21，P < 0.01），与事件影响、抑郁和倦怠呈正且强的偏相关（r = 0.59 - 0.69，P < 0.01），与心理韧性和生活质量呈负偏相关（r = -0.43至 -0.54，P < 0.01）。
我们的研究首次给出了香港心脏病患者中CDI-SF心理测量特性的结果。心理测量结果支持CDI-SF作为中国背景下心脏困扰的一种精确、有效且可靠的测量工具。
