Validation of the Pediatric Evaluation of Disability Inventory in an Italian Population with Autism Spectrum Disorder: a Cross-Sectional Study.

Objectives: To measure psychometric properties of the Italian version of the Pediatric Evaluation of Disability Inventory (PEDI-I) in a population with Autism Spectrum Disorder (ASD).

Methods: The PEDI-I was administered to different children with ASD. The internal consistency was examined by using Cronbach's Alpha, while the intraclass correlation coefficient (ICC) was used to investigate both inter-observer and intra-observer reproducibility.
