Using an implementation science framework, this study examines the impact of a multicomponent professional development (PD) approach implemented by internal peer coaches on early intervention providers’ use of Family Guided Routines-Based Intervention. The experimental study used a single-case multiple baseline design across participants, replicated in three sites with early interventionist (EI) providers (n = 9) and families with infants and toddlers (n = 18) in community-based Part C programs. Data indicate a functional relation between the multicomponent PD approach and EIs’ use of the intervention. A between-case standardized mean difference effect size was used to confirm the results of the visual analysis. The implications for the use of implementation science frameworks to build competency drivers within early intervention systems are discussed.

本研究使用实施科学框架，研究了内部同伴教练实施的多成分专业发展（PD）方法对早期干预提供者使用基于家庭指导的例行干预的影响。该实验研究使用了针对参与者的单案例多基线设计，并在三个地点与早期干预（EI）提供者（n = 9）和有婴幼儿的家庭（n= 18）在基于社区的C部分计划中。数据表明多组分局部放电方法与EIs干预措施之间的功能关系。病例间标准化的平均差异效应大小用于确认视觉分析的结果。讨论了在早期干预系统内使用实施科学框架构建能力驱动因素的含义。
