Abstract
BackgroundDiabetic 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.MethodsThis 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.ResultsIn 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.ConclusionsThe Persian version of the DFSQ-UMA has good validity and reliability, and given its good psychometric properties, it can be used in future studies.

According to the results of a meta-analysis by Zhang et al, The prevalence of diabetic foot ulcers in the world was 6.3%, which is higher in men than in women and in type II diabetic patients than in type I diabetics [5]

Summary
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. Diabetes is the most common metabolic disease in the world with an increasing prevalence rate. End-stage renal disease, foot infection, and blindness are common complications of diabetes that severely affect patients’ quality of life [2]. According to the results of a meta-analysis by Zhang et al, The prevalence of diabetic foot ulcers in the world was 6.3%, which is higher in men than in women and in type II diabetic patients than in type I diabetics [5]
