Abstract:
Objective:To test the reliability and validity of the Self-management Demand Questionnaire for Elderly Patients with Chronic Heart Failure.Methods:In October 2019, convenience sampling was used to select 425 elderly patients with chronic heart failure from 11 general hospitals in Shanghai and Jiangxi Province for pre-survey. Formal questionnaires were formed through item analysis and exploratory factor analysis. In December 2019, 494 elderly patients with chronic heart failure from 11 general hospitals in Shanghai and Jiangxi Province were selected for a formal survey. Confirmatory factor analysis and reliability test were used to evaluate the reliability and validity of the questionnaire.Results:In the first phase of the survey, a total of 425 questionnaires were distributed, and 387 valid questionnaires were recovered. In the second phase of the survey, a total of 494 questionnaires were distributed, and 484 valid questionnaires were recovered. The formal questionnaire included 42 items in 5 dimensions. Five common factors were extracted by exploratory factor analysis, and their cumulative variance contribution rate was 75.538%. The Cronbach's α coefficient of the questionnaire was 0.982, the split-half reliability was 0.871, and the content validity index was 0.891. Confirmatory factor analysis showed that the model fit was good.Conclusions:The Self-management Demand Questionnaire for Elderly Patients with Chronic Heart Failure has good reliability and validity, and can be used as a tool to evaluate the self-management needs of elderly patients with chronic heart failure in China.
