A Randomized Web-Based Physical Activity Intervention in Adolescent Survivors of Childhood Cancer
- To compare changes in levels of moderate and vigorous physical activity over 24 weeks.
- To compare changes in cardiorespiratory fitness, muscular strength and flexibility over
Participants will be randomized to one of three groups. Participants in the control group
will receive an activity monitor and educational materials, but will not have access to the
interactive website. Participants randomized to the two intervention groups will be given
access to a rewards program delivered via an interactive website, an activity monitor, and
educational materials. Individual physical activity data can be viewed by study participants
after uploading information from their monitors to the interactive website. One intervention
group will receive minimal rewards, while the other group will receive immediate incentives
as well as the minimal rewards as they move from one level to the other on the website.
After 24 weeks, changes in cardiorespiratory fitness, muscular strength, flexibility, and
physical function will be compared between the two intervention groups and the control
Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Investigator, Outcomes Assessor), Primary Purpose: Supportive Care
Change in daily average of moderate and vigorous physical activity (MVPA) levels between groups
The impact of the intervention will be assessed at the end of 24 weeks by comparing physical activity levels at baseline, week 12, and week 24 in each group. Data will be collected each time a participant accesses the website (or connects the accelerometer - for the control group) over the entire 24 week period, resulting in access to data on daily levels of physical activity over a 24 week period.
