Objectives: To evaluate the effects of a social cognitive theory (SCT) Web site intervention on college female physical activity and to determine if SCT variables mediated physical activity.

Methods: Ninety-one sedentary volunteers (intervention n = 45; control n = 46) completed questionnaires measuring self-regulation, outcome expectancy value, self-efficacy, and physical activity at baseline, 6 weeks, and 6 months.

Results: The intervention increased days of moderate physical activity at 6 weeks, and self-regulation mediated this effect. The effect was not sustained at 6 months.

Conclusion: E-communications is an effective method to acutely increase self-regulation skills and moderate physical activity.

Keywords: e-communications; exercise behavior; social cognitive theory
