The aim of this study is to evaluate the psychometric properties of the Physical Health Care Self-Efficacy Scale in a sample of university students in the health field, as well as to complement the data obtained in the study by Ornelas et al. (2011). The research was conducted with 495 participants, of which 200 were women (M = 18.6 years, SD = 1.7) and 295 were men (M = 18.8 years, SD = 1.5). The three-factor structure proposed by Ornelas et al. (2011) (Nutrition, Physical Health, and Hydration) was confirmed through confirmatory factor analysis of the scale, with the results showing that it is adequate and consistent with the expected fit indices. On the other hand, the scale's accuracy was analyzed by gender using the factorial invariance analysis procedure, finding that the factorial structure, factor loadings, and intercepts do not show differences in measurement between men and women. However, significant differences were observed in the mean scores obtained in the Nutrition and Physical Health subscales, with higher scores for the male gender. According to the results, the scale is suitable for use with university students in the health field, and it also demonstrates that self-efficacy perception differs by gender. It is concluded that future research should explore the validity of this scale to strengthen its applications in educational and health promotion contexts.
