Abstract

Purpose

This methodological study evaluated the psychometric properties of the Self-Care of Coronary Heart Disease Inventory version 3 (SC-CHDI v3) in a Korean context.

Methods

The SC-CHDI v3 was translated into Korean following a rigorous translation process. Participants were 452 patients who had experienced coronary heart disease (CHD), all recruited from a tertiary hospital in Korea. Exploratory and confirmatory factor analyses were performed to test construct validity. Concurrent validity was examined by correlating scores from the Korean version of the SC-CHDI v3 with those from the Cardiac Self-Efficacy Scale. Internal consistency was analyzed using Cronbach's alpha and McDonald's omega.

Results

The Korean version of the SC-CHDI v3 consists of 21 items, excluding two from the original instrument. The self-care maintenance subscale identified a two-factor structure: “treatment adherence” and “health-promoting behaviors.” The goodness-of-fit indices were satisfied: χ² = 18.19, p = .110, comparative fit index (CFI) = .97, Tucker-Lewis Index (TLI) = .95, and standardized root mean square residual (SRMR) = .04. The self-care monitoring subscale consisted of a one-dimensional structure (“monitoring behaviors”) and the goodness-of-fit indices were satisfied: χ² = 19.19, p = .059, CFI = .99, TLI = .99, and SRMR = .04. The self-care management subscales had a two-factor structure of “consulting behaviors” and “problem-solving behaviors.” The goodness-of-fit indices were satisfied: χ² = 16.44, p = .037, CFI = .99, TLI = .98, and SRMR = .03. Scores from the Cardiac Self-Efficacy Scale showed a positive correlation with the Korean version of SC-CHDI v3 subscales. Reliability estimates were ≥ .80 for all subscales except for the self-care maintenance subscale.

Conclusions

The Korean version of the SC-CHDI v3 consists of 21 items in 3 subscales and is a valid and reliable instrument. Therefore, healthcare providers can effectively utilize it to assess the self-care levels of patients with CHD.

韩国版冠心病自我护理量表第 3 版的心理测试。

目的：本方法学研究评估了冠心病自我护理量表第 3 版（SC-CHDI v3）在韩国背景下的心理测量特性：SC-CHDI v3经过严格的翻译程序被翻译成韩文。参与者为 452 名冠心病（CHD）患者，均来自韩国一家三级医院。为检验结构效度，进行了探索性和确认性因子分析。通过将韩国版 SC-CHDI v3 的得分与心脏自我效能感量表的得分进行相关性分析，检验了并发效度。采用 Cronbach's alpha 和 McDonald's omega 分析了内部一致性：结果：韩国版 SC-CHDI v3 包括 21 个项目，其中不包括原工具中的两个项目。自我护理维持分量表具有双因素结构："治疗依从性 "和 "健康促进行为"。拟合优度指数符合要求：χ2 = 18.19，p = 0.110，比较拟合指数 (CFI) = 0.97，塔克-刘易斯指数 (TLI) = 0.95，标准化均方根残差 (SRMR) = 0.04。自我护理监控子量表由一维结构（"监控行为"）组成，拟合优度指数符合要求：χ2 = 19.19，p = 0.059，CFI = 0.99，TLI = 0.99，SRMR = 0.04。自我护理管理分量表具有 "咨询行为 "和 "解决问题行为 "的双因子结构。拟合优度指数符合要求：χ2 = 16.44，p = .037，CFI = .99，TLI = .98，SRMR = .03。心脏自我效能量表的得分与韩国版 SC-CHDI v3 分量表呈正相关。除自我保健维持量表外，其他所有分量表的信度估计值均≥.80：韩国版 SC-CHDI v3 包括 3 个分量表中的 21 个项目，是一个有效且可靠的工具。因此，医疗服务提供者可以有效地利用它来评估心脏病患者的自我护理水平。
