The diagnosis of avoidant restrictive food intake disorder in the presence of gastrointestinal disorders: Opportunities to define shared mechanisms of symptom expression.

ABSTRACT:

Objective

Individuals with a gastrointestinal (GI) disorder often alter their diet to manage GI symptoms, adding complexity to understanding the diverse motivations contributing to food avoidance/restriction. When a GI disorder is present, the DSM-5 states that Avoidant/Restrictive Food Intake Disorder (ARFID) can be diagnosed only when eating disturbance exceeds that expected. There is limited guidance to make this determination. This study attempts to address this gap by characterizing the presentation of ARFID in adults with and without a self-reported GI disorder.

Method

Participants were 2,610 adults ages 18-44 who self-identified as "picky eaters." Participants reported on motivations for food avoidance, affective experiences towards food, and perceived impairment. Res
