Abstract
PURPOSE: Down Syndrome (DS) is a common genetic disorder caused by trisomy 21. Due to cognitive challenges associated with DS, individuals often experience difficulty performing activities of daily living (ADLs), at levels that can range from mild to significant. This study aimed to measure psychometric properties of the Italian version of the Pediatric Evaluation of Disability Inventory (PEDI-I) in the DS population. METHODS: The PEDI-I was administered to children with DS. The internal consistency was examined using Cronbach's Alpha. Test-retest reliability was demonstrated by intraclass correlation coefficient (ICC) and Bland–Altman plots. The concurrent validity was evaluated with the Italian version of the Barthel Index. RESULTS: The PEDI-I was administered to 54 children with DS. Cronbach's Alpha showed statistically significant values (0.899 –0.986). The ICC confirmed the reproducibility of the scale with a range of (0.988 –1), while Bland-Altman plots showed a smallest detectable change of (0.18–1.63). The Pearson Correlation Coefficient with the Barthel Index showed statistically significant values for all PEDI-I subscales (range 0.75–0.95). CONCLUSION: The study provides evidence of good test-retest reliability and convergent validity when used in children with DS. Other psychometric proprieties need to be investigated in future studies. [ABSTRACT FROM AUTHOR]
