Heart failure (HF) self-care is an important component of disease management and the focus of many interventions.
The aim of this study was to evaluate the validity and reliability of the nine-item European HF Self-care Behavior Scale (EHFScB-9) in a sample of 200 adults from the USA with symptomatic HF.
Psychometric tests included item and confirmatory factor analyses, convergent and discriminant validity, and internal consistency.
Item-total correlations ranged from 0.25 to 0.65. Many fit indices for the EHFScB-9 and the four-item consulting behaviors scale reached thresholds of acceptability. As expected, the EHFScB-9 was associated with other measures of HF self-care but not with quality-of-life. Coefficient α was 0.80 for the EHFScB-9 and 0.85 for the consulting behaviors subscale.
The EHFScB-9 was a valid and reliable measure of HF self-care among English-speaking US adults with symptomatic HF.
心力衰竭（HF）自我护理是疾病管理的重要组成部分，也是许多干预措施的重点。
本研究旨在评估 200 名有症状 HF 的美国成年人样本中，九项欧洲心力衰竭自我护理行为量表（EHFScB-9）的有效性和可靠性。
心理测量学测试包括项目和验证性因子分析、收敛和判别有效性以及内部一致性。
项目-总分相关性范围为 0.25 至 0.65。EHFScB-9 和四项咨询行为量表的许多拟合指数达到了可接受的标准。正如预期的那样，EHFScB-9 与 HF 自我护理的其他测量指标相关，但与生活质量无关。EHFScB-9 的系数 α 为 0.80，咨询行为分量表的系数 α 为 0.85。
EHFScB-9 是一种有效且可靠的针对有症状 HF 的讲英语的美国成年人 HF 自我护理的测量工具。
