The wide range of prevalence estimates is partly due to the lack of standardized, validated measures of GI symptoms among people with ASD. The goal of this study was to (1) develop a measure, which included non\u2010verbal and mealtime behaviors, to assess for GI symptoms and (2) evaluate its psychometric characteristics. This was accomplished by drawing on two existing tools, Autism Treatment Network Gastrointestinal Inventory and the Brief Autism Mealtime Behavior Inventory, and deriving new items, to create the \u201cASD Gastrointestinal and Related Behaviors Inventory\u201d (ASD\u2010GIRBI). The ASD\u2010GIRBI was piloted in an online registry of families with a child with ASD. A psychometric analysis was carried out in a sample of 334 children aged 6\u201317\u00a0years with ASD, resulting in a 36\u2010item tool. The Cronbach's alpha for the overall scale was 0.88. Exploratory factor analysis identified a seven\u2010factor model (1. Bowel movement pain; 2. Aggressive or disruptive during mealtimes; 3. Particular with foods; 4. Abdominal pain and upset stomach; 5. Refusing food; 6. Constipation and encopresis; 7. Motor or other behaviors). Following validation in an independent sample with clinical evaluation of GI symptoms, this tool will be helpful for both research and clinical purposes.<\/jats:p>","DOI":"10.1002\/aur.2707","type":"journal-article","created":{"date-parts":[[2022,3,18]],"date-time":"2022-03-18T05:53:41Z","timestamp":1647582821000},"page":"1142-1155","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Characteristics of the autism spectrum disorder gastrointestinal and related behaviors inventory in children"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8190-2385","authenticated-orcid":false,"given":"Calliope","family":"Holingue","sequence":"first","affiliation":[{"name":"Department of Mental Health Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"},{"name":"Wendy Klag Center for Autism and Developmental Disabilities Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"},{"name":"Center for Autism and Related Disorders Kennedy Krieger Institute  Baltimore Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luther G.","family":"Kalb","sequence":"additional","affiliation":[{"name":"Department of Mental Health Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"},{"name":"Wendy Klag Center for Autism and Developmental Disabilities Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"},{"name":"Center for Autism and Related Disorders Kennedy Krieger Institute  Baltimore Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rashelle","family":"Musci","sequence":"additional","affiliation":[{"name":"Department of Mental Health Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"},{"name":"Wendy Klag Center for Autism and Developmental Disabilities Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Colleen","family":"Lukens","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry and Behavioral Sciences at The Children's Hospital of Philadelphia  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li\u2010Ching","family":"Lee","sequence":"additional","affiliation":[{"name":"Wendy Klag Center for Autism and Developmental Disabilities Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"},{"name":"Department of Epidemiology Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jamie","family":"Kaczaniuk","sequence":"additional","affiliation":[{"name":"Department of Mental Health Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"},{"name":"Wendy Klag Center for Autism and Developmental Disabilities Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle","family":"Landrum","sequence":"additional","affiliation":[{"name":"Department of Mental Health Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"},{"name":"Wendy Klag Center for Autism and Developmental Disabilities Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timothy","family":"Buie","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Hepatology and Nutrition Harvard Medical School  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
