Abstract:
Objective:To develop the Fear of Disease Progression Scale for Patients with Acute Myocardial Infarction, and test its reliability and validity.Methods:The first draft of the scale was formed through literature review, qualitative interviews, and Delphi expert consultations. From March to July 2020, convenience sampling method was adopted to conduct a formal survey of 200 patients with acute myocardial infarction admitted to the Department of Cardiology in three ClassⅢ Grade A hospitals in Jiangsu Province. The formal scale was formed through the project analysis and exploratory factor analysis, and its reliability and validity were determined. 200 questionnaires were distributed, and 178 valid questionnaires were recovered, with a valid recovery rate of 89.00%.Results:The final scale contained 17 items, and exploratory factor analysis extracted 3 common factors, and the cumulative contribution rate of variance was 62.671%. The item-level content validity index ( I- CVI) was from 0.83 to 1.00, the scale-level content validity index ( S- CVI) was 0.82, and the average S- CVI was 0.97. The Cronbach's α coefficient of the total scale was 0.892, the half-reliability was 0.764, and the test-retest reliability was 0.964. Conclusions:The developed Fear of Disease Progression Scale for Patients with Acute Myocardial Infarction has good reliability and validity, which can be used to assess the current status of fear of disease progression in patients with acute myocardial infarction.
