Abstract:

Objective To develop a self-assessment scale of home volume management for patients with chronic heart failure（CHF），and to test its reliability and validity. Methods With the self-care theory as the theoretical framework，the initial scale was developed through literature analysis，qualitative interview and expert consultation. A questionnaire survey was conducted on 598 patients with CHF who were treated or reviewed in a tertiary hospital in Hangzhou from September 2022 to January 2023 to test the reliability and validity of the scale. Results The exploratory factor analysis extracted 4 common factors with the cumulative variance contribution rate of 61.268%. The results of confirmatory factor analysis showed that the main evaluation indicators were all within the acceptable range of the judgment standard. The item-level content validity index ranged from 0.853 to 1.000；the scale-level content validity index/average was 0.951. The Cronbach’s α coefficient，half reliability and retest reliability of the overall scale were 0.930，0.723 and 0.867，respectively. Conclusion The self-rating scale of home volume management for CHF patients has good reliability and validity，and it can effectively assess the level of home volume management for CHF patients.

摘要：

目的 编制适合慢性心力衰竭（chronic heart failure，CHF）患者居家容量管理的自我评估量表，并验证其信效度。 方法 以自我护理理论为理论框架，通过文献分析、质性访谈、专家函询法编制量表初稿。便利选取2022年9月—2023年1月杭州市某三级甲等医院598例CHF患者进行调查，对量表初稿进行信效度检验。 结果 CHF患者居家容量管理自评量表包含自我护理评估、自我护理维持、自我护理管理、自我护理信心4个维度、27个条目。探索性因子分析共提取4个公因子，累计方差贡献率为61.268%。验证性因子分析显示，各主要评价指标均在判断标准可接受范围。条目水平的内容效度指数为0.853~1.000，量表水平的内容效度指数为0.951。量表总的Cronbach’s α系数、分半信度系数、重测信度分别为0.930、0.723、0.867。 结论 编制的CHF患者居家容量管理自评量表具有良好的信效度，可有效评估CHF患者居家容量管理水平。
