Youth Activity Profile
he Youth Activity Profile (YAP) is a self-report instrument designed to facilitate the collection of physical activity in schools (for both assessment and education purposes). The instrument was developed by our team and calibrated through a series of studies led by Dr. Pedro Saint Maurice for his dissertation research. An online version of the YAP was developed to facilitate use by schools. It is being used in the large NFL PLAY 60 FITNESSGRAM Partnership Project and has also been incorporated into the overall FITNESSGRAM battery as a school activity assessment.
To try out the demo application go to www.youthactivityprofile.org and select Demo (You will need to type in the word "Demo" to access the tool)
Ongoing Calibration Work
The innovative aspect of the Youth Activity Profile is that the items are calibrated to provide accurate estimates of physical activity (PA) and sedentary behavior. The figure at right shows the concept of calibration and the overall level of agreement for assessing PA in different segments of the day.
The calibration models are currently being refined in the ongoing Youth Physical Activity Measurement Study. Details on the project are available at www.youthactivitystudy.com
