Occupational Therapy Feeding and Eating Interventions for Autism Spectrum Disorders and Pervasive Developmental Disorders: A Systematic Review

Due to the limited evidence and lack of methodological rigor regarding feeding and issues in children with Autism Spectrum Disorders (ASD) and Pervasive Developmental Disorders (PDD), clinicians who treat children with these diagnoses rely on the limited amount of information and many are not aware of evidence-based interventions (Ahearn, Castine, Nault, & Green, 2001; Marshall, Hill, & Dodrill, 2013). The purpose of this scholarly project is to gather, critique, and determine efficacy of occupational therapy feeding and eating interventions for children with ASD and PDD. We systematically reviewed literature for higher-level evidence, as defined by Level III evidence or above, in regards to occupational therapy feeding and eating interventions for children with ASD and PDD in studies that were published between January 2000 and December 2015 and located in PubMed, OT Search, Cumulative Index of Nursing and Allied Health Literature (CINAHL), and the American Journal of Occupational Therapy (AJOT). Our search yielded a total of 7,189 titles and abstracts that were narrowed through the screening process to 27 articles for review. The secondary review resulted in 11 articles, which received a full-text review. A total of 9 articles were found to meet inclusion criteria and be appropriate for critical appraisal. The results of these articles were compiled in an evidence table and a systematic review manuscript was specifically written for the AJOT. Our scholarly project highlights the various discrepancies regarding research for occupational therapy feeding and eating interventions for children with ASD and PDD. Recommendations for future research and implications for occupational therapy practice include the need for higher-level evidence to support the practice of occupational therapy practitioners and the development of a specific protocol to standardize occupational therapy treatment for feeding and eating difficulties among children with ASD and PDD
