There is a dearth of published research evaluating behavior-analytic assessment and treatment of avoidant/restrictive food intake disorder (ARFID) given the recent revisions in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. In this study, therapists conducted periodic food preference assessments to help guide treatment for a typically developing child with ARFID and food selectivity. Further, therapists evaluated a treatment package including demand fading, escape prevention, and self-monitoring to increase food variety. Consumption increased during treatment with target foods; however, preference shifts were minor when compared to the pretreatment food preference assessment. Variety continued to increase overtime using the same treatment package and treatment effects were generalized to family meals and other locations.
