| Zusammenfassung: | Purpose To critically appraise the measurement properties of questionnaires measuring participation in children and adolescents (0–18 years) with a disability. Methods Bibliographic databases were searched for studies evaluating the measurement properties of self-report or parent-report questionnaires measuring participation in children and adolescents (0–18 years) with a disability. The methodological quality of the included studies and the results of the measurement properties were evaluated using a checklist developed on consensus-based standards. Results The search strategy identified 3,977 unique publications, of which 22 were selected; these articles evaluated the development and measurement properties of eight different questionnaires. The Child and Adolescent Scale of Participation was evaluated most extensively, generally showing moderate positive results on content validity, internal consistency, reliability and construct validity. The remaining questionnaires also demonstrated positive results. However, at least 50 % of the measurement properties per questionnaire were not (or only poorly) assessed. Conclusions Studies of high methodological quality, using modern statistical methods, are needed to accurately assess the measurement properties of currently available questionnaires. Moreover, consensus is required on the definition of the construct 'participation' to determine content validity and to enable meaningful interpretation of outcomes.
