Summary
Brief summary (as posted)
This randomized controlled trial will test a multicomponent intervention to increase exercise Outcome Expectations (OEs) and assess effects of OE changes on exercise intentions and levels of exercise. Sixty early stage breast cancer survivors will be recruited from the Duke Cancer Institute. Participants will be randomized to the exercise OE intervention or an attention control group. Both groups will receive the American Cancer Society diet and exercise guidelines and an accelerometer. The intervention group will also receive an OE workbook containing self-directed activities to increase OEs by focusing on OE importance (value placed on the outcome(s)), certainty (perceived probability outcome(s) will occur); and accessibility (frequency with which the outcome(s) are thought of). The attention control group will receive a workbook containing the same activities focused on diet, rather than exercise.

- description
- Intervention arm participants will receive: 1) the ACS exercise and diet guidelines; and 2) an exercise outcome expectation workbook. The workbook contains self-directed activities to increase OE importance, certainty, and accessibility. The workbook will aim to make participants aware of the breadth and depth of OEs by first providing a global overview of the many positive exercise outcomes breast cancer survivors may experience. Importance will be increased through elaboration of why outcomes are important to the participant; and certainty will be increased by narrative messages from other breast cancer survivors and an oncologist. Accessibility will be increased by having the participant think about the association between exercise and its outcomes.
