Cardiac rehabilitation has showed the potential to improve health outcomes of patients with coronary heart disease. However, the adherence of patients participating in cardiac rehabilitation is unsatisfactory due to some barriers. The quantitative instrument for measuring cardiac rehabilitation adherence is scarce. Hence, the purpose of this study was to develop a scientific tool and assess its psychometric properties in patients with coronary heart disease.
The psychometric properties of the revised scale were tested with 509 patients. Item analysis was conducted to evaluate the discrimination and homogeneity of the scale. Content validity was evaluated by content validity index and Exploratory factor analyses and confirmatory factor analyses were used to examine the factor structure of the scale. Reliability was evaluated by Cronbach's coefficients and split-half reliability coefficients.
A scale covering five dimensions and thirty-three items was developed for evaluating cardiac rehabilitation adherence. The content validity index of the scale was 0.96. In exploratory factor analysis, a five-factor structure model was confirmed, explaining 71.255% of the total variation. In confirmatory factor analysis, the five- factor structure was supported by appropriate fitting indexes. In terms of reliability, the Cronbach's coefficient of the scale was 0.909 and the spilt-half reliability coefficient of the scale was 0.765.
The newly developed self-completion scale is reliable and valid. It appears to be a sound instrument for nurses and a broader range of healthcare professionals to effectively evaluate the cardiac rehabilitation adherence.
心脏康复已显示出改善冠心病患者健康结局的潜力。然而，由于一些障碍，参与心脏康复的患者依从性并不理想。用于测量心脏康复依从性的定量工具稀缺。因此，本研究的目的是开发一种科学工具并评估其在冠心病患者中的心理测量特性。
对509例患者测试修订后量表的心理测量特性。进行项目分析以评估量表的区分度和同质性。通过内容效度指数评估内容效度，并采用探索性因子分析和验证性因子分析来检验量表的因子结构。通过克朗巴赫系数和分半信度系数评估信度。
开发了一个涵盖五个维度和33个条目的量表，用于评估心脏康复依从性。该量表的内容效度指数为0.96。在探索性因子分析中，确认了一个五因子结构模型，解释了总变异的71.255%。在验证性因子分析中，五因子结构得到了适当拟合指数的支持。在信度方面，该量表的克朗巴赫系数为0.909，分半信度系数为0.765。
新开发的自填式量表可靠且有效。它似乎是护士和更广泛的医疗保健专业人员有效评估心脏康复依从性的良好工具。
