Associations Between Avoidant/Restrictive Food Intake Disorder Dimensions and Obsessive‐Compulsive Symptomatology

open access: yesEuropean Eating Disorders Review, EarlyView.
ABSTRACT Objective Although obsessive‐compulsive disorder (OCD) commonly co‐occurs with anorexia nervosa and bulimia nervosa, less is known about its relationship with avoidant/restrictive food intake disorder (ARFID) dimensions. Whether associations between ARFID dimensions and OCD differ by sex is also unclear.
