Description
Summary:Avoidant/Restrictive Food Intake Disorder (ARFID) is a possible comorbidity in patients with Inflammatory Bowel Disease (IBD). Early detection and intervention are crucial to prevent malnutrition and related complications. However, ARFID often remains undiagnosed due to its subtle presentation. Methods: This multicenter study enrolled 235 patients with IBD at German tertiary referral centers between March and September 2025. The Nine Item Avoidant/Restrictive Food Intake disorder screen (NIAS), a screening tool for ARFID, was translated into German and administered at baseline and follow-up. The validity and reliability of the NIAS German were assessed via hypothesis testing and Cronbach’s α coefficient.
