Background: This session will take a closer look at Avoidant/Restrictive Food Intake Disorder, one of the "new" eating disorders in DSM-5, exploring etiology, epidemiology, and multidisciplinary treatment. Teaching methods will include an in-depth case study and experiential components.
This session will begin with an overview of the DSM-V criteria for Avoidant/Restrictive Food Intake Disorder (ARFID) and a review of the latest research on this “new” diagnosis. We will take a closer look at differential diagnosis and highlight possible symptom overlap of ARFID with anorexia nervosa, anxiety, obsessive compulsive disorder, and sensory processing disorder. We will summarize recent findings on etiology and prevalence rates for ARFID and present an in-depth case study (including recorded interviews with the adolescent male patient and his parents) to illustrate the characteristic presentation of this disorder. Following the case study we will discuss multi-disciplinary treatment approaches and modalities for ARFID including medical management, nutrition therapy, dialectical behavior therapy, exposure and response prevention, mindfulness, expressive arts therapies, and family therapy. Participants will have an opportunity to ask questions and participate in discussion.
With the release of the diagnostic and statistical manual—fifth edition (DSM-5) came some significant changes in eating disorder classification including the replacement of feeding disorder of infancy or early childhood with “avoidant/restrictive food intake disorder” (ARFID). This “new” and broader diagnosis is not simply a replacement term as chart review studies suggest a percentage of patients diagnosed with eating disorder not otherwise specified (EDNOS) under DSM-IV-TR would now fall under the category of ARFID. This session will take a closer look at ARFID with the purpose of helping clinicians better understand what to look for and how to treat this complex disorder. The session will explore what we know about etiology, epidemiology, and best practices based on available research. Teaching methods will include an in-depth case study of a 14 year old male seen in inpatient, partial hospitalization and outpatient levels of care over the course of two years.
