NMSK II Pediatric Outcome Measures Practice Test

PEDI-CAT represents a shift to computer-adaptive testing that uses item response theory for scoring. As the respondent answers items, the system estimates their current level of function and selects subsequent questions that will provide the most information about that level. This tailoring often means fewer questions while keeping precision, and the scoring is driven by IRT estimates. In contrast, the traditional PEDI uses a fixed set of items that are the same for everyone and is typically caregiver-reported without adaptive item selection. It also relies on standard scoring of those fixed items rather than a model-based estimate of ability. The other statements don’t fit because PEDI-CAT is not fixed-item, it isn’t designed only for adults, and its scoring isn’t identical to PEDI.
