BACKGROUND
The Self-care of Heart Failure Index (SCHFI) is an empirically tested instrument for measuring the self-care of patients with heart failure.
OBJECTIVE
The aim of this study was to develop a simplified Chinese version of the SCHFI and provide evidence for its construct validity.
METHODS
A total of 182 Chinese with heart failure were surveyed. A 2-step structural equation modeling procedure was applied to test construct validity.
RESULTS
Factor analysis showed 3 factors explaining 43% of the variance. Structural equation model confirmed that self-care maintenance, self-care management, and self-care confidence are indeed indicators of self-care, and self-care confidence was a positive and equally strong predictor of self-care maintenance and self-care management. Moreover, self-care scores were correlated with the Partners in Health Scale, indicating satisfactory concurrent validity.
CONCLUSION
The Chinese version of the SCHFI is a theory-based instrument for assessing self-care of Chinese patients with heart failure.
背景
心力衰竭自我护理指数（SCHFI）是一种经过实证检验的用于测量心力衰竭患者自我护理情况的工具。
目的
本研究旨在开发SCHFI的简体中文版，并为其结构效度提供证据。
方法
共对182名中国心力衰竭患者进行了调查。采用两步结构方程建模程序来检验结构效度。
结果
因子分析显示3个因子解释了43%的方差。结构方程模型证实，自我护理维持、自我护理管理和自我护理信心确实是自我护理的指标，且自我护理信心是自我护理维持和自我护理管理的积极且同样强大的预测因子。此外，自我护理得分与健康伙伴量表相关，表明具有令人满意的同时效度。
结论
SCHFI中文版是一种基于理论的用于评估中国心力衰竭患者自我护理情况的工具。
