Vocal stereotypy is a commonly occurring challenging behavior in children with autism spectrum disorder (ASD) that is frequently maintained by automatic reinforcement and often interferes with skill acquisition. Matched stimulation (MS), and response interruption and redirection (RIRD) are two interventions that have been demonstrated to be effective in reducing the occurrence of vocal stereotypy with participants with ASD. The current study sought to determine if the combination of MS (noncontingent music) and RIRD was more effective at reducing vocal stereotypy than RIRD alone and if the parents of children with ASD found the combination of MS and RIRD more socially valid than RIRD alone. The results suggested that the combined intervention resulted in greater suppression of vocal stereotypy and increased occurrences of on-task behavior in both participants. Additionally, RIRD required fewer implementations and had a shorter duration when combined with MS. Results suggest that the combination of MS and RIRD may be an effective intervention outside of highly controlled settings.
发声刻板行为是自闭症谱系障碍（ASD）儿童中常见的具有挑战性的行为，通常由自动强化维持，并且经常干扰技能的获得。匹配刺激（MS）和反应中断与重定向（RIRD）是两种已被证明可以有效减少 ASD 参与者发声刻板行为的干预措施。本研究旨在确定 MS（非条件音乐）和 RIRD 的组合是否比单独使用 RIRD 更能有效地减少发声刻板行为，以及 ASD 儿童的父母是否认为 MS 和 RIRD 的组合比单独使用 RIRD 更具有社会有效性。结果表明，联合干预导致发声刻板行为的抑制作用更大，并且在两个参与者中任务行为的发生次数增加。此外，当与 MS 结合使用时，RIRD 需要的实施次数更少，持续时间更短。结果表明，MS 和 RIRD 的组合可能是一种在高度受控环境之外的有效干预措施。
