A new cognitive behavior therapy for adolescents with avoidant/restrictive food intake disorder in a day treatment setting: A clinical case series.

Objective: Avoidant/restrictive food intake disorder (ARFID) is a new diagnosis in the DSM-5 Feeding and Eating Disorders section, for which very limited treatment research has been carried out, yet. A new, 4-week exposure based cognitive behavioral therapy (CBT) day treatment, which integrated the inhibitory learning principles, was developed for adolescents with ARFID, and tested in the current study.

Method: A nonconcurrent multiple baseline design was used in a clinical case series of eleven 10- to 18-year-old patients.
