The aim of the study was to test the reliability and validity of the Italian translation of the PedsQL 4.0 Generic Core Scales and the PedsQL 3.0 Rheumatologic Module in a sample of rheumatologic children in Italy.
The PedsQL 4.0 and the PedsQL 3.0 were administered to rheumatic and healthy children. 102 children 5-18 years old and 132 parents of children 2-18 years old were tested. Additionally, the Child Health Questionnaire - Parent Form 50 - was administered to the rheumatologic sample.
Internal consistency reliability for group comparisons reached the recommended coefficient alpha of 0.70 for PedsQL 4.0 and PedsQL 3.0. The inter-correlation between these last ones was highly significant. The correlation between the PedsQL 4.0 and the CHQ was statistically significant.
The Italian version of the PedsQL 4.0 and PedsQL 3.0 Rheumatology Module demonstrate acceptable reliability and validity for both patient self-report and parent proxy-report.
