title: Can personality bridge the intention-behavior gap to predict who will exercise?
abstract: OBJECTIVE
  To explore whether HEXACO personality domains could incrementally increase the prediction of exercise behavior above Theory of Planned Behavior (TPB) variables, and whether personality moderated the intention-behavior gap.
  
  
  METHODS
  US College students (N = 1017) completed demographic, TPB, HEXACO domain and exercise behavior measures.
  
  
  RESULTS
  The TPB predicted physical activity, accounting for 45% and 39% of variance in intention and behavior, respectively. Regarding personality domains, lower emotionality significantly predicted intention, and lower honesty-humility significantly predicted behavior, but these were small effects. Personality did not moderate the intention-behavior gap.
  
  
  CONCLUSIONS
  Personality has a limited direct role in predicting exercise intention and behavior beyond the TPB. The prediction of exercise behavior from honesty-humility highlights the importance of considering the HEXACO personality model.
