The Eagerness for Physical Activity Scale (EPAS) validated in this study is based on the belief that eagerness for physical activity should be seen as a major outcome of interventions and physical activity contexts. The aim of the study was to introduce the concept of eagerness into physical activity research, to validate EPAS, and to explore its relationship with maximal oxygen uptake (VO2max) and motivation. A multi-study validation approach was used. Convergent and discriminant validity was supported and the scale displayed high internal consistency across all studies. When controlling for self-determined motivation, eagerness for physical activity related positively to VO2max, thus supporting incremental validity above and beyond intrinsic motivation, identified regulation, extrinsic regulation, and a-motivation. Based on our results we recommend not only the application of EPAS in the assessment of how intervention programs and regular types of activity contexts affect people of all ages, but also the introduction of the concept of eagerness into physical activity and health research and policy in general.
