Evaluating the Use of Stability Ball Chairs for Children with ASD in a Clinic Setting.

This study used an alternating treatments embedded within a nonconcurrent multiple baseline across participants design to evaluate the effects of a stability ball chair on the on-task and in-seat behavior for three children with autism in a clinic setting. Results indicated increases for both in-seat and on-task behavior with the stability ball chair compared to a standard table chair, however, results varied across participants. On-task behavior had a greater increase across participants compared to in-seat behavior with the stability ball chair. Social validity results found that therapists had an overall positive view of stability ball chairs. This study provides clinicians with options for alternative seating to increase the on-task and in-seat behavior of children with autism. This study extends the use and evaluation of alternative seating, from typically studied settings and contexts, such as classrooms, to clinic settings with younger populations. © Association for Behavior Analysis International 2021.
