Evaluating a Social and Communication Intervention for Preschoolers

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to test the effectiveness of a school-based treatment aimed at increasing language and social skills in preschool-aged children with autism spectrum disorder (ASD). Through interactive development (continually seeking educator feedback for intervention improvement) and implementation of the intervention, the investigators hope to provide a feasible and practical means for educators to work with children with ASD in real world, large scale settings. ASD preschool educators, the children enrolled in their classes, between the ages of 3 and 6 years and their families may join.

Detailed Description
-----------------
In Phase 4, KKI staff trained Delaware preschool teachers to serve as model coaches and educators through the Delaware Autism Program. Families whose children were enrolled in participating classrooms were consented through DAP using the school's consent to be videotaped. Any families who did not consent for their child to be videotaped for this training received the nonparticipant consent form currently utilized in this study and staff videotaping took every effort to keep those children out of frame when taping. This cohort involved KKI study team members training 1-2 coaches, who then trained five Delaware school teachers. The IES model was implemented in the teacher's classrooms (n= 5-10 students participating in each classroom; 20-40 children total). In the current phase of the study, Phase 5 and 6, KKI study team members will continue the evaluation of the IES model, by testing the efficacy of the intervention model in a larger sample (Phase 5) and then analyzing the corresponding data (Phase 6). The larger efficacy study (phase 5) will be conducted on teachers and students recruited from public school districts in Maryland, Delaware, and Pennsylvania using the same IES model and recruitment methods in the previous phases.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in educator instruction to meet fidelity of intervention. | Fidelity will be monitored throughout the duration of the intervention by KKI staff to assess the quality and consistency with which educators implement the intervention. | approximately 4-, 8-, 12-, 16-, 20-, 24-, 28-, 32-, and 36-weeks into the intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |

| Change in Baseline Mullen Scales of Early Learning |  | 9 months into treatment | 
| Change in Child's Baseline Spontaneous Imitation Task |  | 9 months into treatment | 
| Change in Child Classroom-based Social Communication Performance |  | 9 months into treatment | 
| Change in parent perception of child behavior as recorded by the Autism Composite score of the PDDBI (parent version) |  | 9 months into treatment |
