How multiple motives facilitate decisions to exercise in contexts with tempting alternatives: evidence from two scenario studies

Objective Both affectively-charged and reflective motivation may be necessary to sustain recommended physical activity (PA) guidelines, especially in contexts with tempting alternatives. However, our understanding of how different sources of motivation facilitate PA across contexts is limited. This paper presents a novel value-based model that specifies how affectively-charged and reflective motivation interact to support PA decisions based on available alternatives at a given decision point.
