Occupational Therapy Using Zones of Regulation™ Concepts: A Feasibility Study.

There is a lack of peer-reviewed research on occupational therapy using Zones of Regulation™ concepts for autistic youth. The purpose of this article is to describe the feasibility of a newly-developed occupational therapy intervention using Zones of Regulation™ concepts (OT-ZOR) for autistic youth. Specifically, we aimed to evaluate: (a) participant recruitment, retention, and attendance; (b) intervention fidelity, safety, and assessment completion; (c) intervention acceptability; and (d) preliminary participant outcomes. A single-arm feasibility study was completed with outcome measures before and after 10 weeks of OT-ZOR. Fourteen autistic youth ages 6 to 13 completed the study. Youth attended 94% of OT-ZOR sessions. Providers achieved 97% fidelity to the intervention. Occupational therapists and caregivers expressed overall satisfaction with the OT-ZOR intervention. Youth demonstrated significant decreases in irritability, hyperactivity, emotional reactivity, and dysphoria. OT-ZOR is feasible to implement, acceptable to providers and caregivers, and may improve self-regulation in autistic youth.
