Assessing Fears of Negative Consequences in Children With Symptoms of Avoidant Restrictive Food Intake Disorder.

Objective: Fear of Aversive Consequences (FOAC), such as choking or vomiting, is an important associated feature of Avoidant/Restrictive Food Intake Disorder (ARFID). However, the manifestation of FOAC in young children is poorly understood. This study aimed to describe the fears of children with ARFID symptoms and examine the concordance between parent and child ratings of fear.

Method: Child-reported FOAC was assessed using an interview designed for children between 6 and 10 years old, the Gustatory Avoidance and Gastrointestinal Stress Symptoms (GAGSS). Parents were administered a semi-structured diagnostic interview regarding their child's symptoms, the Pica, ARFID, and Rumination Interview.

Results: Among 68 children with ARFID diagnoses or symptoms (41.2% female, 85.3% White, mean age = 8.2 years, SD = 1.1 years; range 5.2-9.9 years), 91.2% of children endorsed at least one fear relative to 26.5% of parents. Among parent-child dyads, 36.8% disagreed about the child's fear of stomach pain (κ = 0.12) and 48.5% disagreed about the child's fear of vomiting, (κ = 0.08), both indicating low inter-rater reliability. On average, children endorsed 4.3 (SD = 2.3) fears out of 9 options. The most frequently endorsed fears were that food will "taste bad," (n = 43, 63.2%), "make you gag" (n = 37, 54.4%), and "look disgusting" (n = 36, 52.9%).

Discussion: Findings highlight ways in which fear may manifest in children with ARFID that are not easily discernable by adults. Greater precision in depicting childhood fears may facilitate the earlier detection of problematic eating behaviors.
