AIM: To investigate whether the items of the Danish, Dutch, and Norwegian versions of the Pediatric Evaluation of Disability Inventory - Computer Adaptive Test (PEDI-CAT) align with the location-order used in the original algorithm and to assess their structural validity. METHOD: Three convenience samples without disability (0-20 years; Danish [n = 318], Dutch [n = 349], Norwegian [n = 362]) responded to the language-specific versions. Item location-order was estimated using the graded response model and structural validity was tested using confirmatory factor analysis and Rasch analysis. RESULTS: For most items, the item location-order was largely consistent with the location-order used in the original PEDI-CAT algorithm. Items showing a different order were primarily related to the daily activity domain. However, the confirmatory factor analysis and Rasch analysis indicated poor model ...
