Adaptive Behavior Change in Autism: Outcomes from a Comprehensive, Interdisciplinary Clinical Care Cohort

Purpose: The purpose of this study was to examine the effects of a medically centered, interdisciplinary treatment model on adaptive behavior in children with Autism Spectrum Disorder (ASD). The Cortica model involves a comprehensive program including behavioral and developmental therapies, overseen by a neurodevelopmental physician. Here, we investigated how adaptive behaviors change over time during care at Cortica. Methods: We analyzed changes in the Vineland Adaptive Behavior Scales over the course of Cortica care compared to a community sample comprising longitudinal data from the National Database for Autism Research (NDAR). Results: Using propensity score weights to match cohorts based on baseline functioning, multilevel growth curve models showed significant Cohort × Time interactions for the Adaptive Behavior Composite (ABC) score and all subscale scores, indicating increased growth in adaptive behavior skills for children in the Cortica cohort relative to NDAR. Conclusions: Results of this study highlight the importance of using adaptive behaviors as a primary outcome in clinical research studies and suggest that a personalized, multidisciplinary approach to intervention can result in improved adaptive behavior skills over time.
