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\u2019s Alpha. Test-retest reliability was demonstrated by intraclass correlation coefficient (ICC) and Bland\u2013Altman 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\u2019s Alpha showed statistically significant values (0.899 \u20130.986). The ICC confirmed the reproducibility of the scale with a range of (0.988 \u20131), while Bland-Altman plots showed a smallest detectable change of (0.18\u20131.63). The Pearson Correlation Coefficient with the Barthel Index showed statistically significant values for all PEDI-I subscales (range 0.75\u20130.95). 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.<\/jats:p>","DOI":"10.3233\/prm-190674","type":"journal-article","created":{"date-parts":[[2022,6,17]],"date-time":"2022-06-17T12:19:32Z","timestamp":1655468372000},"page":"487-497","source":"Crossref","is-referenced-by-count":1,"title":["Evaluation of test-retest reliability and concurrent validity of the Italian version of the pediatric evaluation of disability inventory in children with down syndrome: A cross-sectional study"],"prefix":"10.1177","volume":"15","author":[{"given":"Giovanni","family":"Galeoto","sequence":"first","affiliation":[{"name":"Department of Human Neurosciences, Sapienza University of Rome, Rome, Italy"},{"name":"Scientific Institute for Research, Hospitalization and Healthcare (IRCCS) Neuromed, Pozzilli, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ester","family":"Mignolli","sequence":"additional","affiliation":[{"name":"Sapienza University of Rome, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco","family":"Tofani","sequence":"additional","affiliation":[{"name":"Department of Human Neurosciences, Sapienza University of Rome, Rome, Italy"},{"name":"Professional Development, Continuous Education and Research Service, Bambino Ges\u00f9 Children\u2019s Hospital, Scientific Institute for Research, Hospitalization and Healthcare (IRCCS), Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carla","family":"Sogos","sequence":"additional","affiliation":[{"name":"Department of Human Neurosciences, Sapienza University of Rome, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Annamaria","family":"Servadio","sequence":"additional","affiliation":[{"name":"Local Health Board Roma 2, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donatella","family":"Valente","sequence":"additional","affiliation":[{"name":"Department of Human Neurosciences, Sapienza University of Rome, Rome, Italy"},{"name":"Scientific Institute for Research, Hospitalization and Healthcare (IRCCS) Neuromed, Pozzilli, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Berardi","sequence":"additional","affiliation":[{"name":"Department of Human Neurosciences, Sapienza University of Rome, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"key":"10.3233\/PRM-190674_ref1","unstructured":"Domino FJ , editor.
