Pilot Study: Occupational Therapy in an Equine Environment for Youth With Autism.

Despite growing prevalence, research investigating occupational therapy incorporating horses for youth with autism is limited. This study aimed to (a) pilot a screening, evaluation, and intervention protocol of occupational therapy in an equine environment and (b) assess preliminary effects on occupational performance goals, behavior, and social functioning of youth with autism. A multiple baseline single-case experimental design was used. Six youth with autism participated in a no-treatment baseline phase and 10 weeks of intervention. Therapists implemented the intervention with 95% fidelity. Per parent report, participants improved in occupational performance goals, social motivation, and communication; four demonstrated decreased irritability and hyperactivity. This research operationalizes a screening, evaluation, and intervention protocol for occupational therapy in an equine environment, and demonstrates it may improve occupational, behavioral, and social outcomes for youth with autism. Next steps include manualizing the intervention, refining feasibility measures, and implementing a randomized controlled efficacy study.
