The level of perceived exercise benefits and barriers is one of the key influencing factors of cardiac exercise rehabilitation (CER). There is a lack of validated tools to assess coronary heart disease (CHD) patients' exercise perception.
The aim of this study is to develop a scale assessing CHD patients' perceived exercise benefits and barriers (CHD-PEBBS) and test its reliability and validity.
A total of 205 CHD patients were recruited for a cross-sectional survey. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to extract factors, delete items and evaluate construct validity. The Cronbach's alpha coefficient and test-retest reliability were used to test the reliability of the scale.
Based on the health belief model, this study developed a perceived benefits and barriers framework. CFA showed that the fit indices (such as χ/df=2.281, CFI=0.93, RMSEA=0.079) were all acceptable A total of 6 factors were extracted through EFA, with a cumulative variance contribution rate of 75.52%. The perceived benefits subscale included 3 dimensions: "improving physiological indicators", "improving quality of life" and "improving physiological function" with a total of 12 items. The perceived barriers subscale also included 3 dimensions: "lacking of exercise support", "worrying about adverse consequences" and "poor exercise experience or perception" with a total of 10 items. The Cronbach's alpha coefficient of the scale was 0.917, and the test-retest reliability was 0.941.
The CHD-PEBBS shows good reliability and validity, which may be used to evaluate the CER perception level of CHD patients, offering precise targets and pathways for exercise rehabilitation interventions in nursing.
运动益处和障碍的认知水平是心脏运动康复（CER）的关键影响因素之一。目前缺乏用于评估冠心病（CHD）患者运动认知的有效工具。
本研究旨在开发一种评估冠心病患者运动益处和障碍认知的量表（CHD-PEBBS），并检验其信效度。
共招募205例冠心病患者进行横断面调查。采用探索性因子分析（EFA）和验证性因子分析（CFA）提取因子、删除条目并评估结构效度。采用Cronbach's α系数和重测信度检验量表的信度。
基于健康信念模型，本研究构建了运动益处和障碍认知框架。CFA结果显示拟合指数（如χ/df=2.281，CFI=0.93，RMSEA=0.079）均可接受。通过EFA共提取6个因子，累积方差贡献率为75.52%。运动益处分量表包括“改善生理指标”“提高生活质量”“改善生理功能”3个维度，共12个条目。运动障碍分量表也包括“缺乏运动支持”“担心不良后果”“运动体验或认知差”3个维度，共10个条目。量表的Cronbach's α系数为0.917，重测信度为0.941。
CHD-PEBBS具有良好的信效度，可用于评估冠心病患者的CER认知水平，为护理中的运动康复干预提供精准目标和途径。
