RESUMO
BACKGROUND AND AIMS: The parent-proxy reports can offer complementary informations or be the only source of Quality of Life measurement in young children. The aim of this study was to provide and validate the Italian version of the recently published parent-proxy pCMT-QOL for patients aged 8-18 years old, making it available for possible trials in Italian speaking children. METHODS: The English-language instrument was translated and adapted into the Italian language using standard procedures: translation, transcultural adaptation, and back-translation. Parent-proxy pCMT-QOL was administered to parents of patients with a genetic diagnosis of CMT, aged 8-18 years old. All parents were retested 2 weeks later to assess reliability. RESULTS: A total of 21 parents of CMT patients (18 CMT1A, 2 CMT2A, 1 CMT2K) were assessed during their children clinical appointments. The Italian-pCMT-QOL showed a high test-retest reliability; none of the parents had any difficulties with the completion of the questionnaire and no further revisions were necessary after completion. INTERPRETATION: The Italian parent-proxy pCMT-QOL is a reliable, culturally adapted, and comparable version of the original English instrument. This questionnaire will improve the quality of the follow-up and will make it possible to monitor more accurately the severity of the disease in Italian-speaking families.
