Abstract

Background: Diabetic foot self-care refers to a group of self-management behaviors that can reduce the incidence of foot ulcers and amputations. It is necessary to have a valid and reliable standard tool to measure foot self-care in diabetic patients. This study aimed to evaluate the psychometric properties of the Persian version of the Diabetic Foot Self-Care Questionnaire of the University of Malaga, Spain (DFSQ-UMA) in Iran. Methods: This cross-sectional study was conducted with 407 diabetic patients who were selected using a convenient sampling method. Construct validity was assessed by exploratory (with 207 patients) and confirmatory (with 200 patients) factor analyses. Internal consistency was calculated using Cronbach�s alpha and McDonald�s omega coefficients. Results: In the exploratory factor analysis, three factors with eigenvalues of 3.84, 2.41, and 2.26 were extracted that together explained 56.74 of the total variance of diabetic foot self-care. A Cronbach�s alpha of 0.865 was found for the total instrument. Conclusions: The Persian version of the DFSQ-UMA has good validity and reliability, and given its good psychometric properties, it can be used in future studies. © 2021, The Author(s).
