Social Cognitive Theory and Physical Activity After Endometrial Cancer
MD Anderson Study Status
Researchers propose to apply Social Cognitive Theory to improve understanding of the mechanisms of physical activity adherence for endometrial cancer survivors participating in a physical activity intervention. The specific aims of the study are: 1. To test a Social Cognitive Theory-based model of physical activity adoption among sedentary endometrial cancer survivors receiving an intervention to increase physical activity. The model includes hypotheses about the effect of self-efficacy and outcome expectations on physical activity adherence, the effects of four sources of efficacy information (mastery experience, verbal persuasion, modeling, and physiological feedback) on self-efficacy and subsequent exercise adherence, and the influence of physical activity outcomes on subsequent self-efficacy, outcome expectations, and physical activity. 2. To elucidate the influence on self-efficacy of cardiorespiratory fitness and somatic sensations while engaging in physical activity. 3. To determine whether the received dose of an intervention based on Social Cognitive Theory is related to physical activity adherence. 4. To test the effects of adherence to physical activity on endometrial cancer survivors' quality of life and stress as assessed by self-report and salivary cortisol. 5. To test the feasibility of a web-based maintenance intervention for women who have completed the phone counseling portion of the study.
