BACKGROUND
The benefits of home-based cardiac rehabilitation exercise are well-established and depend on long-term adherence. However, there is no uniform and recognized cardiac rehabilitation criterion to assess home-based cardiac rehabilitation exercise adherence for patients with cardiovascular disease. This study aimed to develop a home-based cardiac rehabilitation exercise adherence scale and to validate its psychometric properties among patients with chronic heart failure.
METHODS
The dimensions and items of the scale were created based on grounded theory research, literature content analysis, and defined by a Delphi survey. Item analysis was completed to assess the discrimination and homogeneity of the scale. Factor analysis was adopted to explore and validate the underlying factor structure of the scale. Content validity and calibration validity were evaluated using the Delphi survey and correlation analysis, respectively. Reliability was evaluated by Cronbach's α coefficients, split-half reliability coefficients, and test-retest reliability coefficients.
RESULTS
A scale covering four dimensions and 20 items was developed for evaluating home-based cardiac rehabilitation exercise adherence. The content validity index of the scale was 0.986. In exploratory factor analysis, a four-factor structure model was confirmed, explaining 75.1% of the total variation. In confirmatory factor analysis, the four-factor structure was supported by the appropriate fitting indexes. Calibration validity of the scale was 0.726. In terms of reliability, the Cronbach's α coefficient of the scale was 0.894, and the Cronbach's α coefficients of dimensions ranged from 0.848 to 0.914. The split-half reliability coefficient of the scale was 0.695. The test-retest reliability coefficient of the scale was 0.745.
CONCLUSION
In this study, a home-based cardiac rehabilitation exercise adherence scale was developed and its appropriate psychometric properties were confirmed.
背景
家庭心脏康复运动的益处已得到充分证实，且依赖于长期坚持。然而，目前尚无统一且公认的心脏康复标准来评估心血管疾病患者对家庭心脏康复运动的依从性。本研究旨在开发一种家庭心脏康复运动依从性量表，并在慢性心力衰竭患者中验证其心理测量学特性。
方法
该量表的维度和条目基于扎根理论研究、文献内容分析创建，并通过德尔菲调查进行界定。完成项目分析以评估量表的区分度和同质性。采用因子分析来探索和验证量表的潜在因子结构。分别使用德尔菲调查和相关分析评估内容效度和校标效度。通过克朗巴哈α系数、分半信度系数和重测信度系数评估信度。
结果
开发了一个涵盖四个维度和20个条目的量表，用于评估家庭心脏康复运动依从性。该量表的内容效度指数为0.986。在探索性因子分析中，确认了一个四因子结构模型，解释了总变异的75.1%。在验证性因子分析中，四因子结构得到了适当拟合指标的支持。该量表的校标效度为0.726。在信度方面，该量表的克朗巴哈α系数为0.894，各维度的克朗巴哈α系数在0.848至0.914之间。该量表的分半信度系数为0.695。该量表的重测信度系数为0.745。
结论
本研究开发了一种家庭心脏康复运动依从性量表，并确认了其适当的心理测量学特性。
