Self-regulatory efficacy as a mediator between attributions and intention for health-related physical activity.

The purpose of the present study was to examine whether self-regulatory efficacy would mediate the relationship between individual attributional dimensions for typical exercise levels and intentions to maintain these levels during final exams among university students. Using a prospective design, participants completed measures of attributions for typical activity levels, self-regulatory efficacy and intention to be active during a forthcoming exam period. Results revealed that self-regulatory efficacy partially mediated the relationship between attributional dimensions and intentions for both moderate and mild exercise levels. The results provide initial support for the suggestion that when examining moderate and mild intensity exercise, it is plausible that causality flows from stability of attributions to intentions, at least partially through self-regulatory efficacy.
