Book excerpt: Abstract: The purpose of this study was to evaluate the effect of a 12-week social cognitive theory (SCT) based intervention designed to influence targeted theoretical variables and subsequent changes in the physical activity of sedentary patients recovering from breast cancer. Seventy-four volunteers (intervention group n=36; control group n=38) were recruited by mass email and written letter solicitation. Subjects completed an online questionnaire measuring the social cognitive theory variables self-regulation, self-efficacy, outcome expectancy value and exercise role identity, as well as a 7-day physical activity recall at baseline, 6-weeks and 12-weeks. The intervention group received an email based on SCT. For six weeks the intervention group received weekly email messages and the following six weeks the participants received email messages every other week addressing specific SCT variables. The control group did not receive any information regarding the specific SCT variables, nor did they have access to an e-counselor. ANCOVAs were used to analyze differences between the control and intervention group at 6 and 12 weeks. Baseline measures were used as the covariate. Alpha level was set at 0.05 a priori. The results show the intervention was successful in increasing exercise role identity at 6- and 12-weeks, self-efficacy at 12-weeks, days of self-reported moderate physical activity at 12-weeks, days of self-reported vigorous physical activity at 6- and 12-weeks and total days of self-reported physical activity at 6- and 12-weeks. In addition, a mediating effect was found for self-efficacy at 12-weeks and exercise role identity at 6- and 12-weeks. There was not a significant difference between the groups for self-reported days of moderate physical activity at 6-weeks. In conclusion, e-communication is an effective method to acutely increase exercise role identity, exercise self-efficacy, self-reported days of moderate and vigorous physical activity as well as total days of self-reported physical activity. Furthermore, changes in exercise role identity and self-efficacy mediate physical activity. Further research should investigate how to maintain exercise role identity, self-efficacy and physical activity, along with the influence of other SCT variables.
