Abstract:
Objective:To develop the Self-management Behavior Questionnaire for Middle-aged and Young Patients with Myocardial Infarction and test its reliability and validity.Methods:Using social cognitive theory, self-efficacy theory, and self-management theory as theoretical frameworks, a preliminary questionnaire was formed through literature review, semi-structured interviews, and Delphi expert consultation. Convenience sampling was used to select middle-aged and young patients with myocardial infarction from the First Affiliated Hospital of Henan University of Chinese Medicine, Henan Provincial Chest Hospital, and the Second Affiliated Hospital of Zhengzhou University from June to July 2022 for investigation, and item analysis and exploratory factor analysis of the questionnaire were conducted. From August to November 2022, middle-aged and young patients with myocardial infarction from the Heart Center of the First Affiliated Hospital of Henan University of Chinese Medicine were selected for investigation, and confirmatory factor analysis and reliability testing of the questionnaire were conducted.Results:A total of 300 and 480 questionnaires were distributed, respectively, and 280 and 468 valid questionnaires were collected, with effective response rates of 93.33% (280/300) and 97.50% (468/480), respectively. The Self-management Behavior Questionnaire for Middle-aged and Young Patients with Myocardial Infarction included 31 items. The total Cronbach 's α coefficient of the questionnaire was 0.918, the half reliability coefficient was 0.853, and the retest reliability coefficient was 0.975. The content validity index of the questionnaire level was 0.965, and the content validity index of the item level was 0.830 to 1.000. Exploratory factor analysis extracted 6 common factors with a cumulative variance contribution rate of 69.795%. Confirmatory factor analysis showed that the model fitted well and the questionnaire factor structure was stable. Conclusions:The Self-management Behavior Questionnaire for Middle-aged and Young Patients with Myocardial Infarction developed in this study has good reliability and validity, which can provide references for medical and nursing staff to evaluate the self-management behavior of middle-aged and young patients with myocardial infarction.
