Evidence on effective communication interventions for persons with Rett syndrome is needed to drive the standard of care with this population. This study examined the effectiveness of an intervention package to teach multiple, aided communication requests for two persons with Rett syndrome (ages 27 and 7) through within participant, adapted multiple baseline designs across items/activities. Participants were taught graphic mode requests on speech generating devices, with access methods based on motor ability; one participant responded by pressing a touch screen, and one participant responded by fixed eye-gaze. Results are discussed in relation to the effectiveness of the intervention packages on increasing the accuracy of independent request selection responses emitted and the number of sessions required to reach an performance criterion for both participants. Difficulties during initial prompting and during prompt fading with the eye-gaze response are considered. The findings suggest implications related to emerging evidence on the intervention methods to teach requesting skills to this population, and future research directions for communication intervention options for persons with severe communication impairment and limited motor repertoires.
需要有关于雷特综合征患者有效沟通干预措施的证据，以推动针对这一人群的护理标准。本研究通过参与者内、跨项目/活动的适应性多基线设计，检验了一套干预方案对两名雷特综合征患者（分别为27岁和7岁）教授多种辅助沟通请求的有效性。参与者在语音生成设备上学习图形模式请求，访问方法基于运动能力；一名参与者通过按压触摸屏做出反应，另一名参与者通过固定注视眼睛做出反应。讨论了干预方案在提高两名参与者发出的独立请求选择反应的准确性以及达到表现标准所需的会话次数方面的有效性。考虑了初始提示期间以及与注视眼睛反应相关的提示消退期间的困难。研究结果表明了与向该人群教授请求技能的干预方法的新证据相关的意义，以及针对严重沟通障碍和运动技能有限的人的沟通干预选项的未来研究方向。
