Validation of the Italian version of the pediatric CMT quality of life outcome measure.

ABSTRACT

The pediatric Charcot-Marie-Tooth (CMT) specific quality of life (QOL) outcome measure (pCMT-QOL) is a recently developed and validated patient-reported measure of health QOL for children with CMT. The aim of this study was to provide and validate an Italian version of the pCMT-QOL. The original English version was translated and adapted into Italian using standard procedures. pCMT-QOL was administered to patients genetically diagnosed with CMT, aged 8 to 18 years. A retest was given 2 weeks later to assess reliability in all patients. A total of 22 patients (median age 14 years, DS 2.5; MF 11) affected with CMT (19 CMT1A, 2 CMT2A, 1 CMT2K) were assessed as part of their clinical visit. The Italian-pCMT-QOL demonstrate a high test-retest reliability. None of the patients experienced difficulty in completing the questionnaire, no further corrections were needed after administration in patients. The Italian-pCMT-QOL is a reliable, culturally adapted and comparable version of the original English pCMT-QOL. This questionnaire is expected to be valuable in monitoring disease progression and useful for future clinical trials in Italian-speaking children with CMT.
