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.

本研究使用嵌入在参与者设计的非并发多基线中的交替治疗来评估稳定球椅对诊所环境中三名自闭症儿童的任务和就座行为的影响。结果表明，与标准桌椅相比，稳定球椅的座位内和任务行为都有所增加，但是，参与者的结果各不相同。与使用稳定球椅的座位内行为相比，参与者的任务行为有更大的增加。社会效度结果发现，治疗师对稳定性球椅有总体积极的看法。这项研究为临床医生提供了替代座位的选择，以增加自闭症儿童的任务和就座行为。这项研究扩展了替代座椅的使用和评估，
