The potential role of occupational therapy in the treatment of avoidant/restrictive food intake disorder.

Most individuals with avoidant/restrictive food intake disorder (ARFID) never receive treatment, and treatment needs far exceed the current capacity of mental health services. Occupational therapy (OT) focuses on enhancing function in daily activities, including eating and feeding. Given OT's rich history in mental health and pediatric feeding disorder treatment, we spotlight the potential role of OT in ARFID treatment, current knowledge, and opportunities for future research. Through a preliminary exploratory inquiry involving a review of current literature and clinical practice, we investigated OT's current involvement, knowledge, and interprofessional collaborative practice gaps in ARFID treatment. While many occupational therapy practitioners (OTPs) engage in ARFID treatment, interventions lack rigorous evaluation, and there is limited evidence defining OT's distinct role in interprofessional ARFID treatment. OTPs are uniquely positioned to provide interventions for individuals with ARFID across the lifespan, though research is needed to evaluate the efficacy of OT interventions. Future research suggestions include standardizing OT approaches to ARFID treatment and conducting single-case experiments and randomized controlled trials to compare OT approaches with alternative methods. Recommendations to address practice gaps include enhancing ARFID education for OT students and practitioners and fostering a greater understanding of OT's role on the interprofessional team. PUBLIC SIGNIFICANCE: Individuals with ARFID face barriers to eating that impact their health and function. On a multidisciplinary team, OTPs can treat diverse client populations by identifying and addressing barriers to daily participation, such as physical impairments, trauma history, and environmental barriers. More research is needed to evaluate the efficacy of OT practices in ARFID treatment.
