A qualitative study examining the validity and comprehensibility of physical activity items: developed and tested in children with juvenile idiopathic arthritis

摘要

BackgroundNot all physical activity (PA) questionnaires (PAQ) gather information regarding PA intensity, duration, and modes and only a few were developed specifically for children. We assessed children’s comprehensibility of items derived from two published PAQs used in children along with three items designed to ascertain PA intensity in order to assess comprehensibility of items and identify response errors. We modified items to create a new PAQ for children (>ASCeND). We hypothesized that children would have comprehension difficulties with some original PAQ items and that >ASCeND would be easier to comprehend, and would improve recall and reporting of PA.
