Variation in Intolerance of Uncertainty Scores across Restrictive Eating Disorders and their Correlation with Eating Disorder Symptom Severity and Clinical Impairment

This study aims to examine variation in intolerance to uncertainty scores across restrictive eating disorders and their correlation with Eating Disorder Symptom Severity and Clinical Impairment. Using data from the University of Chicago's Eating Disorders Program 123 participants were segregated in the three diagnoses (AN = 64, ARFID = 18 and Atypical AN = 41). Exploratory results found that Intolerance to uncertainty was higher in patients diagnosed with AN than ARFID. Correlational results indicate an association between intolerance to uncertainty and eating disorder symptom severity.
