Preschool classrooms provide a unique context for supporting the development of children with social-communication challenges. This study is an uncontrolled clinical trial of an adapted professional development intervention for preschool teachers (Social Emotional Engagement-Knowledge & Skills-Early Childhood). Social Emotional Engagement-Knowledge & Skills-Early Childhood is a low-resource-intensive, transdiagnostic intervention to address the learning needs of children with social-communication challenges and consists of four asynchronous online modules and three synchronous coaching sessions. The current research evaluated the feasibility and acceptability of intervention and research procedures, implemented in authentic early childhood education settings. Participants included one teacher and one target child with social-communication challenges from 25 preschool classrooms, sampled to maximize variability. Overall, the current research revealed high levels of feasibility, with 9 out of 10 benchmarks met: (a) procedures for participant recruitment reliably identified a neurodiverse sample of children with teacher-reported social-communication challenges; (b) teachers showed high levels of program engagement and Social Emotional Engagement-Knowledge & Skills-Early Childhood completion (76%); and (c) results revealed a robust pattern of gains in Social Emotional Engagement-Knowledge & Skills-Early Childhood classrooms and associations among key outcome measures (including active engagement, student teacher relationship, social-communication competencies). Implications for the design of a subsequent, larger effectiveness-implementation hybrid trial (Type 1) are discussed.Lay AbstractPreschool classrooms provide a unique context for supporting the development of children with social-communication challenges. This study evaluates the feasibility and acceptability of an adapted professional development intervention for preschool teachers (Social Emotional Engagement-Knowledge & Skills-Early Childhood). Social Emotional Engagement-Knowledge & Skills-Early Childhood is a low-resource-intensive, transdiagnostic intervention to address the learning needs of children with a broad range of social-communication challenges in authentic preschool classrooms. The intervention consists of four asynchronous online modules and three synchronous coaching sessions. Participants included one teacher and one target child with social-communication challenges from 25 preschool classrooms from private childcare, Head Start, and public Pre-K programs. Results reveal high levels of Social Emotional Engagement-Knowledge & Skills-Early Childhood feasibility, with 9 out of 10 feasibility benchmarks met: (a) procedures for participant recruitment reliably identified a neurodiverse sample of children with teacher-reported social-communication challenges; (b) teachers showed high levels of program engagement and Social Emotional Engagement-Knowledge & Skills-Early Childhood completion (76%); and (c) results revealed a robust pattern of gains in Social Emotional Engagement-Knowledge & Skills-Early Childhood classrooms and associations among key outcome measures (including active engagement, student–teacher relationship, social-communication competencies). This research prepares a subsequent, larger effectiveness-implementation hybrid trial (Type 1) that investigates the effectiveness of Social Emotional Engagement-Knowledge & Skills-Early Childhood for improving child outcomes and explores facilitators and barriers of program implementation and sustainability.
