The aim of this study was to examine factorial invariance of the Self-efficacy in Diet and Physical Wellness Scale (ECASF) in Mexican university sportsmen and non-sportsmen. The final sample comprised 1.305 Mexican university students (707 women, 598 men), whose average age was 20.46 years (SD=1.87). Confirmatory factorial analyses showed that a five-factor scale is feasible and adequate for both populations. In accordance with statistical and substantial criteria, the five factor structure (physical exercise, nutritional care, problems confrontation, avoiding tobacco, and avoiding alcohol) displayed good indexes of fit both in terms of reliability and validity. Moreover, factorial structure and loads, as well as intercepts, were found to be invariant in both populations; however, differences were found with regard to average values of physical exercise, nutritional care, problems confrontation, and avoiding tobacco. Finally, the present study confirms the validity of a Penta dimensional model proposed in previous studies. Future research should replicate these procedures in populations with different cultural and personal characteristics.
