Evaluating the Reliability and Sensitivity of the VB-MAPP as an Outcome Measure in Autism Research

This study, presented at the 2019 Michigan Autism Conference, explored the inter-rater reliability of the VB-MAPP, a widely used assessment and curriculum guide in autism interventions, and tested its effectiveness as an outcome measure for low-intensity behavioral interventions. The findings show good reliability for milestones and moderate reliability for barriers, with some variability in individual domains. When compared to the Vineland Adaptive Behavior Scale, the VB-MAPP demonstrated a greater sensitivity to detecting gains from low-dosage interventions.
