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

To adapt the American PEDI into a Dutch version, and to establish the content validity of this pediatric functional status instrument.

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.

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.

The expert panel confirmed the functional content and feasibility of the Dutch PEDI for pediatric rehabilitation outcome measurement.
