ABSTRACT The purpose of this study was to improve measurement of physical activity self-efficacy (PASE) in adults with obesity by evaluating relationships between responses to a new battery of PASE Scales and physical activity (PA). Specifically, relationships between a recently proposed two-dimensional (shorter and longer durations) latent PASE conceptualization and PA was evaluated across intensities (moderate, vigorous) and domains (work, transport, domestic, leisure) measured by the PASE Scales. Longitudinal secondary data (N = 461) from the Well-Being and Physical Activity (ClinicalTrials.gov, identifier: NCT03194854) study, which deployed the Fun For Wellness (FFW) intervention, were analyzed. A positive direct effect (latent PASE→PA) was observed for the shorter (but not the longer) duration in each domain at both intensities. A positive indirect effect (FFW→latent PASE→PA) was observed for the shorter (but not the longer) duration in each domain at a moderate (but not vigorous) intensity. These results have implications for PA-promotion in this at-risk population.
