Background: The use of assistive technology, specifically microswitches, with children with RTT has been shown to effectively moderate the impact of their disability on their quality of life⁻ by facilitating access to meaningful leisure and other activities.

Objectives: This study aimed to evaluate the effectiveness of a microswitch intervention on increased choice making, engagement in a targeted sorting activity, and indices of happiness, and decreased stereotypic behaviors for six girls with Rett syndrome. Targeted dependent variables were also assessed at six months post-intervention. Following the intervention study, 90 external raters completed a social validation procedure.

Method: An ABABAB experimental sequence was implemented for each participant with a cross-over effect. A social validation assessment involving 90 external raters was carried out.

Results: Data emphasized an improved performance for each participants involved (i.e., adaptive responses). Five participants showed a capacity of independent choice. One participant seemed to be closely linked to the position of the container. Social raters favorably endorsed the use of the program since they positively evaluated the use of the technology on all the dimensions investigated.

Conclusion: A microswitch intervention may improve choice making and activity engagement for children with Rett syndrome. Further research is needed on the development of more sophisticated forms of individualized technological options to improve opportunities for enhanced engagement and choice-making for individuals with RTT.

背景：RTT儿童使用辅助技术（尤其是微动开关）已被证明可以有效地缓解残疾对其生活质量的影响^-通过促进人们获得有意义的休闲和其他活动。

目的：本研究旨在评估微开关干预对增加六个女孩瑞特综合症的选择，参与有针对性的分类活动和幸福指数以及减少刻板印象行为的干预效果。干预后六个月还评估了目标因变量。干预研究之后，有90位外部评估者完成了一项社会验证程序。

方法：为每个参与者实施ABABAB实验序列，并产生交叉效应。进行了涉及90个外部评估者的社会验证评估。

结果：数据强调了所涉及的每个参与者的绩效都有所提高（即适应性反应）。五名参与者表现出自主选择的能力。一位与会者似乎与集装箱的位置密切相关。社会评价者赞成使用该程序，因为他们在所调查的所有方面都积极评估了该技术的使用。

结论：微动开关干预可以改善Rett综合征儿童的选择和活动参与度。需要开发更复杂形式的个性化技术选择的进一步研究，以增加RTT个人参与和选择的机会。
