Abstract: Objective: To test the factorial structure and reliability of the Brazilian version of the Diabetic Foot Self-Care Questionnaire of the University of Malaga-Spain (DFSQ-UMA-Br). Method: Cross-sectional study for psychometric evaluation of the DFSQ-UMA-Br conducted with 269 people with diabetes who responded to the items of the collection instrument composed of sociodemographic and clinical data and the tested instrument, from February 2024 to February 2025. The internal structure was evaluated using Exploratory and Confirmatory Factor Analysis. Reliability was assessed using Cronbach’s alpha and McDonald’s omega. Results: The factor analysis for the DFSQ-UMA-Br data matrix was adequate (KMO = 0.79 [95% CI] = 0.71–0.82]); Bartlett’s sphericity test = p < 0.001; degree of freedom of 66), indicating that the variables are correlated. Psychometric sensitivity with adequate values of asymmetry (sk = 0.199–3.655) and kurtosis (ku = −0.226–+3.764) proving the normal distribution of data. Conclusions: The DFSQ-UMA-Br is a valid and reliable instrument capable of assessing foot self-care in people with diabetes in the Brazilian population and can be used by nurses and other professionals to promote health in the context of clinical care and research.
