RESUMO
PURPOSE: The study's purpose was to evaluate the concurrent validity of the Child Patient-Reported Outcomes Measurement Information System (PROMIS) PA with the Youth Activity Profile (YAP) and examine its relationship to PROMIS measures of sedentary behavior and fatigue. The PROMIS Pediatric Activity (PA) measure is a newly developed, valid instrument used to collect data on children's lived experiences of short bouts of moderate to rigorous physical activity. METHODS: Participants were ages 8 to 20 years attending a state fair. Child PROMIS measures-PA, Sedentary Behavior, and Fatigue-and the YAP were completed on an iPad. RESULTS: The PROMIS PA and YAP had a positive correlation. The PROMIS PA was not associated with sedentary behavior or fatigue measurements. CONCLUSION: As expected, the PROMIS PA and YAP measure-related PA constructs, the YAP focuses on energy expended while the PROMIS PA indicates perceived response to activity.
