Implementing a Uniform Outcome Measurement Approach for Early Interventions of Autism Spectrum Disorders.

abstract
OBJECTIVE: Naturalistic developmental behavioral interventions (NDBI) for children with autism spectrum disorder (ASD) show evidence for effectiveness for specific social communication targets such as joint attention or engagement. However, combining evidence from different studies and comparing intervention effects across those studies have not been feasible due to lack of a standardized outcome measure of broader social communication skills that can be applied uniformly across trials. This investigation examines the usefulness of the Brief Observation of Social Communication Change (BOSCC) as a common outcome measure of general social communication skills based on secondary analyses of data obtained from previously conducted randomized control trials (RCTs) of three intervention models, the Early Social Intervention (ESI), Early Start Denver Model (ESDM) and Joint Attention Symbolic Play Engagement and Regulation (JASPER). METHOD: The subset of datasets from the three RCTs was created to examine differences in the BOSCC scores between intervention and control groups over the course of the interventions. RESULTS: Based on 582 videos from 207 caregiver-child dyads, the BOSCC noted significant differences between intervention vs. control groups in broad social communication skills within two of the three intervention models which were longer in duration and focused on a broad range of developmental skills. CONCLUSION: The BOSCC offers the potential to take a uniform measurement approach across different intervention models to capture the effect of intervention on general social communication skills but may not pick up the effects of some brief interventions targeting proximal outcomes.
