Validation of the Dutch Giving Youth a Voice Questionnaire (GYV-20): A measure of the client-centredness of rehabilitation services from an adolescent perspective

PURPOSE: The objective was to validate the Dutch translation of the Canadian Giving Youth a Voice Questionnaire (GYV-20) for use in paediatric rehabilitation settings in The Netherlands. The GYV-20 consists of 20 items (assessing four domains) and was designed to evaluate the client-centredness of rehabilitation services from an adolescent perspective. METHOD: The construct validity, concurrent validity, and reliability of the Dutch GYV-20 were determined. Participants were 116 youngsters aged 11 - 21 years (Mean = 15.9; SD = 2.1) recruited through six paediatric rehabilitation settings in The Netherlands. RESULTS: Correlations between the GYV-20 scale scores were positive (r = 0.69 - 0.78). The GYV-20 showed adequate internal consistency, with Cronbach's alpha ranging from 0.76 - 0.81. The ICCs of test-retest reliability ranged from 0.82 - 0.92, which demonstrated good stability of the GYV-20. Dutch adolescents judged the GYV-20 as a valuable and useful tool to evaluate rehabilitation services in The Netherlands. CONCLUSIONS: The Dutch GYV-20 showed sufficient evidence of construct validity and good reliabilities. The Dutch GYV-20 offers users a useful measurement option for various research and clinical purposes.
