A latent profile analysis of the sources of physical activity-specific self-efficacy

Although self-efficacy beliefs are an important predictor of physical activity, the origins of self-efficacy beliefs remain unclear, and a comprehensive joint perspective regarding the sources of self-efficacy is lacking. The present study investigates whether distinct profiles emerge in the sources of self-efficacy regarding physical activity. In a sample of 324 participants, latent profile analysis revealed that a five-profile solution fitted the data best. Significant differences were observed between these profiles concerning self-efficacy and physical activity. Discriminant analysis substantiated the profile assignments. Findings of this study suggest that multiple configurations of self-efficacy sources yield commendable levels of self-efficacy and physical activity. However, elevated levels of negative affect seem to have a detrimental effect on self-efficacy and physical activity, nearly irrespective of the other sources of self-efficacy. Implications of these findings for promoting self-efficacy in a person-centered manner to address the issue of physical inactivity and the concomitant health restrictions are discussed.
