Social Networks of Diffusion and Adoption: Investigating the Network Effects on implementation of evidence-based interventions for early intervention providers of children

对患有自闭症谱系障碍（ASD）的学龄前儿童的早期干预可以导致大量的 认知和沟通结果的改善。1然而， 人口是可变的，从最佳结果到最小收益。2.3可能导致 干预结果的可变性是社区对循证实践的执行不力。45（Dufek et al 2019）。研究表明，治疗团队成员之间的合作动力是一种可塑性 有助于干预反应的因素，并且可以成功地修改以改善干预 在社区环境中取得成果。为了研究协作动力学是否在 对于使用AAC的最低语言学龄前儿童的干预结果，我们将使用社会网络分析， 测试假设，家庭和专业人员之间的高度合作，最低限度的口头 ASD儿童将能够高水平地传播和采用AAC，这反过来会产生更好的效果。 干预结果。

Early interventions for preschoolers with Autism Spectrum Disorder (ASD) can result in substantial improvements across cognitive and communication outcomes.1 However, treatment response in this population is variable, ranging from optimal outcomes to minimal gains. 2,3 One factor that might contribute to variability in intervention outcomes is poor community implementation of evidence-based practices.45 (Dufek et al 2019). Research has identified collaboration dynamics among treatment team members as a malleable factor that contributes to intervention response and can be successfully modified to improving intervention outcomes in community settings. In order to investigate whether collaboration dynamics play a role in intervention outcomes for minimally verbal preschoolers that use AAC, we will use social network analysis to test the hypothesis that high collaboration among family and professionals working with minimally verbal children with ASD will enable high levels of diffusion and adoption of AAC, which will in turn yield better intervention outcomes.
