Abstract:
Objective:To develop the Self-management Scale for Patients with Lower Extremity Peripheral Artery Disease based on Chronic Disease Self-Management Program (CDSMP) and test its reliability and validity.Methods:Using CDSMP as the theoretical framework, a scale was formed through literature review, research group discussions, semi-structured interviews and Delphi expert inquiries. From October 2021 to March 2022, a total of 200 patients with lower extremity peripheral artery disease in the ward of Department of the Vascular Surgery, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were investigated by the convenient sampling to test the reliability and validity of the scale. A total of 200 questionnaires were distributed, and 183 valid questionnaires were recovered, with an effective recovery rate of 91.50%.Results:Cronbach's α coefficient of the overall scale was 0.935; the content validity indexes at the item level of the scale were 0.825-1.000, the content validity index at the scale level was 0.964. The first exploratory factor analysis was conducted without limiting the number of factors, and 5 common factors were obtained, with a cumulative variance contribution rate of 82.330%. According to the gravel map, 4 common factors were limited and extracted from the second exploratory factor analysis, with a cumulative variance contribution rate of 78.856%. The formal scale formed after screening included 4 dimensions and 26 items.Conclusions:The Self-management Scale for Patients with Lower Extremity Peripheral Artery Disease has good reliability and validity, which can be used as a tool for nursing staff to investigate the self-management level of patients with lower extremity peripheral arterial disease.
