| Abstract: | Objectives: To replicate findings for a direct effect of the activity personality trait on exercise behavior while controlling for the Theory of Planned Behavior (TPB), and to investigate a possible moderating effect for gender.Method: Undergraduate students (N=298) completed measures of the TPB, activity trait, and a two-week follow-up of exercise behavior.Results: The activity trait had a significant (p<0.01) direct effect on both exercise intention and behavior while controlling for the TPB, with no moderating effect of gender (p>0.05).Conclusions: The activity trait predicts exercise intention and behavior independent of social cognition even over a short two week period. The TPB may need to broaden its measurement domain in order to mediate the effect of personality on behavior. Moreover, exercise practitioners may need to consider personality when developing interventions. |
