Treatments for Eating Disorders in People with Autism Spectrum Disorder: A Scoping Review

Background: This scoping review aims to synthesize existing evidence on non-pharmacological interventions for managing food selectivity in individuals with autism spectrum disorder (ASD). Specifically, it explores sensory, behavioral, and environmental factors influencing intervention outcomes and examines the role of occupational therapists (OTs) within multidisciplinary teams. Methods: A search was conducted across MEDLINE, EBSCO, Web of Science, OTseeker, and SCOPUS from August 2023 to October 2023. Only experimental studies published in English were included, focusing on behavioral treatments and/or occupational therapy interventions. Results: A total of 1618 studies were identified. After removing duplicates (170 records), 259 full-text articles were assessed for eligibility, resulting in 61 studies included for qualitative synthesis. Conclusions: The findings highlight a wide range of interventions, yet methodological inconsistencies and small sample sizes limit the strength of the evidence. While occupational therapists play an increasing role in feeding interventions, their specific impact remains underexplored. Future research should focus on larger, well-designed studies with standardized outcome measures to better define the effectiveness of interventions and the role of OTs within multidisciplinary teams.
