Abstract

BACKGROUND

Coronary heart disease (CHD) is a leading cause of morbidity and mortality worldwide. The level of self-care after coronary events is closely linked to understanding cardiovascular risk factors and adopting healthier lifestyle behaviors. An appropriate scale can help healthcare providers measure patients' understanding of cardiovascular risk factors and provide educational interventions. This study aimed to translate and conduct a psychometric evaluation of the scale of knowledge of cardiovascular risk factors and lifestyle after coronary events.

METHODS

A standardized guideline was followed for translating and culturally adapting the English version of the Scale of Knowledge of Cardiovascular Risk Factors and Lifestyle after Coronary Events. The study included 300 patients with CHD aged 23 to 90. Exploratory factor analysis (EFA) was used to analyze construct validity. Internal consistency was estimated with Cronbach's alpha (0.98), and the intra-class correlation coefficient (ICC) was used to assess scale stability (0.84).

RESULTS

A total of 300 patients with an average age of 56.6 ± 12.7 were evaluated. Exploratory factor analysis confirmed construct validity, resulting in a 4-factor model comprising knowledge of cardiovascular risks (7 items), knowledge of lifestyle recommendations (6 items), knowledge of cholesterol and blood pressure control (5 items), and knowledge of diabetes (3 items). Together, these factors explained 67.34% of the total variance. The Cronbach's alpha for internal consistency of the scale was 0.851. Additionally, scale stability, as measured by the test-retest method, was 0.84, which is acceptable according to the minimum value of 0.70.

CONCLUSION

The translated Scale of Knowledge of Cardiovascular Risk Factors and Lifestyle after Coronary Events demonstrated strong psychometric properties among patients with CHD. The scale is both reliable and valid, providing healthcare providers with a practical tool to evaluate patient understanding and guide educational efforts aimed at enhancing post-coronary event self-care.

摘要

背景

冠心病（CHD）是全球发病和死亡的主要原因。冠心病事件后的自我护理水平与对心血管危险因素的认识以及采取更健康的生活方式行为密切相关。一个合适的量表可以帮助医疗保健提供者衡量患者对心血管危险因素的了解程度，并提供教育干预措施。本研究旨在翻译并对冠心病事件后心血管危险因素和生活方式知识量表进行心理测量学评估。

方法

遵循标准化指南对冠心病事件后心血管危险因素和生活方式知识量表的英文版本进行翻译和文化调适。该研究纳入了300名年龄在23至90岁之间的冠心病患者。采用探索性因子分析（EFA）来分析结构效度。用Cronbach's α系数（0.98）估计内部一致性，并使用组内相关系数（ICC）评估量表稳定性（0.84）。

结果

共评估了300例平均年龄为56.6±12.7岁的患者。探索性因子分析证实了结构效度，得出一个四因子模型，包括心血管风险知识（7项）、生活方式建议知识（6项）、胆固醇和血压控制知识（5项）以及糖尿病知识（3项）。这些因子共同解释了总方差的67.34%。该量表内部一致性的Cronbach's α系数为0.851。此外，通过重测法测得的量表稳定性为0.84，根据最小值0.70判断是可接受的。
