Dutch adaptation and content validity of the 'Pediatric Evaluation of Disability Inventory (PEDI)'

Purpose: To adapt the American PEDI into a Dutch version, and to establish the content validity of this pediatric functional status instrument. Methods: The adaptation process was based on current scientific guidelines in the field of cross-cultural research. Thirty-one allied health professionals completed a validity questionnaire for the content validity study. Results: The topic 'bicycling' was added to the questionnaire, and adaptations of the text were made without losing the content of the original PEDI. At least 81% of the respondents rated that the most important facets in examining functional status in childhood were represented in the Dutch PEDI. Eighty-seven per cent and 71% of the respondents rated that the PEDI is feasible for discriminative purposes and evaluative purposes, respectively. Conclusion: The expert panel confirmed the functional content and feasibility of the Dutch PEDI for pediatric rehabilitation outcome measurement.
