The purpose of this study is to examine the feasibility, acceptability, and gather preliminary data on outcomes of a 3-month mHealth intervention to promote physical activity among adolescent and young adult (AYA) cancer survivors compared to a delayed intervention control group.
Adolescent and young adult (AYA) survivors are not meeting recommended physical activity guidelines for cancer survivors, and few interventions to date have focused specifically on promoting physical activity among AYAs or capitalized on new technologies to deliver them. This is a pilot randomized controlled trial (RCT) to examine the feasibility, acceptability, and gather preliminary data on outcomes of a 3-month mHealth intervention to promote PA among AYA survivors compared to a delayed intervention control group. This project will focus on how to best integrate self-monitoring with wearable trackers, increase self-efficacy, enhance autonomous motivation, and promote social support in a mobile health behavioral intervention that promotes moderate-to-vigorous intensity physical activity (MVPA) among AYA survivors. Participants will be AYA cancer survivors (N=60), diagnosed at age 15 or older and currently age 18-39. AYA cancer survivors will be recruited from the three comprehensive cancer centers in North Carolina to participate in this study. The behavioral intervention will consist of an activity tracker, Facebook group, weekly email lessons, and weekly tailored feedback emails. Assessments of objectively-measured physical activity and other outcomes will be completed at baseline, 3, and 6 months.

Accrual rate
Number of participants who agreed to participate divided by the number of months of recruitment.
Time frame: Through completion of study enrollment, an average of 6 months.
Participation rate
Percentage of eligible participants who agreed to participate.
Time frame: Through completion of study enrollment, an average of 6 months.
Retention rate at 3 months
Number of intervention participants who completed 3-month measures divided by the number who consented to participate.
Time frame: 3 months
Retention rate at 6 months
Number of intervention participants who completed 6-month measures divided by the number randomized to the intervention group.
Time frame: 6 months
Satisfaction with intervention
Ratings of satisfaction with the intervention, as measured by satisfaction questionnaire.
Time frame: 6 months
Adherence to physical activity monitoring
Number of days physical activity tracked, as measured by Fitbit.
Time frame: Through study completion, 6 months
Physical activity: objective
Change in objective levels of physical activity, as measured by accelerometry (Actigraph), from baseline to 3 months, and 3 months to 6 months.
Time frame: Baseline, 3 months, 6 months
Physical activity: self-report

Change in self-report levels of physical activity, as measured by the Godin Leisure Time Exercise Questionnaire, from baseline to 3 months, and 3 months to 6 months.
Time frame: Baseline, 3 months, 6 months
Sedentary behavior: self-report
Change in self-report levels of sedentary behavior, as measured by the Marshall Sitting Time Questionnaire, from baseline to 3 months, and 3 months to 6 months.
Time frame: Baseline, 3 months, 6 months
Weight
Change in self-reported weight, from baseline to 3 months, and 3 months to 6 months.
Time frame: Baseline, 3 months, 6 months
Intrinsic motivation
Change in intrinsic motivation, as measured by the intrinsic motivation subscale of the Treatment Self-Regulation Questionnaire for Exercise, from baseline to 3 months, and 3 months to 6 months. Responses to four items comprising intrinsic motivation subscale are averaged to yield a score from 1 to 7, with higher values representing higher intrinsic motivation.
Time frame: Baseline, 3 months, 6 months
Self-efficacy for exercise
Change in self-efficacy for exercise, as measured by the Self-Efficacy and Exercise Habits Survey, from baseline to 3 months, and 3 months to 6 months. Responses for two subscales (Sticking to it, Making time for exercise) are averaged to yield a score from 1 to 5, with higher values representing higher self-efficacy for exercise.
Time frame: Baseline, 3 months, 6 months
Social support for exercise
Change in social support for exercise, as measured by the Social Support for Exercise Survey, from baseline to 3 months, and 3 months to 6 months. Responses for three factors (Family participation, Friend participation, Friends on social networking sites participation), ranging from 1 to 5, are summed, with higher values representing higher social support for exercise.
Time frame: Baseline, 3 months, 6 months
