title: Predicting vigorous physical activity using social cognitive theory.
abstract: OBJECTIVE
  To test Social Cognitive Theory (SCT) in predicting future vigorous physical activity among college students.
  
  
  METHODS
  College students (n=350) completed a set of instruments measuring SCT constructs. Their vigorous physical activity was tracked for 4 weeks.
  
  
  RESULTS
  Exercise role identity, self-regulation, outcome expectancy value, social support, self-efficacy, and positive exercise experience accounted for 27% of the variance in days of vigorous physical activity.
  
  
  CONCLUSIONS
  The results supported the use of SCT in understanding factors associated with vigorous physical activity rates among college students.
