A Single Arm Pilot Study to Refine a Novel Approach to Exercise Promotion Based on Affect-regulation

The research grade ActiGraph wGT3X-BT model is a valid measure of physical activity intensity and duration among multiple populations, including breast cancer survivors. Minutes of moderate-vigorous physical activity will be collected from the ActiGraph wGT3X-BT every day for 10-days. Average minutes of moderate-vigorous physical activity completed per day of valid wear time will be calculated.

Time frame: 12-weeks follow-up assessment

Population: Valid wear accelerometer wear time was defined as 5 or more days of 600 minutes wear time at 12-weeks follow-up. N = 28 participants had valid wear time at 12-weeks follow-up, thus N = 28 is the overall number of participants analyzed for this outcome measure.

The Godin Leisure-Time Exercise Questionnaire is a brief self-report measure that asks participants to report how many minutes they spent participating in moderate and vigorous physical activity on a given day. Participants will report total minutes of moderate-vigorous physical activity completed per day for 10-days. Average minutes of moderate-vigorous physical activity completed per day will be calculated.

Time frame: 12-weeks follow-up assessment

The Godin Leisure-Time Exercise Questionnaire is a brief self-report measure that asks participants to report how many minutes they spent participating in moderate and vigorous physical activity on a given day. Participants will report total minutes of moderate-vigorous physical activity completed per day for 10-days. Average minutes of moderate-vigorous physical activity completed per day will be calculated.

Time frame: 2-weeks follow-up assessment

Population: Data was missing from N = 1 participant, total sample size at 2 weeks follow up was N = 30.

Time frame: 6-weeks follow-up assessment

A 4-item self-report measure of affective attitudes for exercise. Response options range from -5 to 5. Responses are summed and then averaged; total scores range from -5 to 5. Higher scores more favorable affective attitudes about exercise.
