To increase the effectiveness of physical activity interventions, researchers should focus on basic behavioral and mediator change research. Therefore, the purpose of study was to examine the mediating effects of a social cognitive theory (SCT) based intervention on female exercise behavior. Subjects were randomly assigned to treatment (n=18) and control (n=18) groups. Both groups received access to the on-site fitness facility, orientation, and individual exercise program. The treatment group received a four-hour intervention designed to enhance the SCT variables. Observations were made at baseline and 6 weeks. All instruments had established reliability and validity. Results show no interaction (time x group) for self-efficacy (p=0.338) or outcome-expectancy values (p=0.25) A significant interaction was found for self-regulation (p < 0.001). Both groups increased their exercise behavior, but the treatment group showed a greater increase. We examined the self-regulation data for a mediating effect because a significant interaction was found. No mediating effect was found for self-regulation, using a three-step regression technique. The mediating results are different than other published research, but the effect of the intervention on self-regulation is similar. This may be due to the observations being compared. In previous research a mediating effect was found for 12-month data and our data are between baseline and 6-weeks. There may be a temporal effect of the intervention on self-regulation skills and exercise behavior. We plan to collect data at 6-months and 12-months to examine this temporal dimension.
