A Progressive Approach to Applied Behavior Analysis

Approximately 1 in 36 children in the United States will be diagnosed with autism spectrum disorder (ASD) and that number is expected to rise according to the CDC. Interventions based on the science of applied behavior analysis (ABA) are one of the most common interventions for autistic individuals. One of the biggest problems facing the field of ABA-based interventions is ineffectiveness of intervention approaches due to the rigid application of ABA-based interventions. Progressive Approach to Applied Behavior Analysis provides practicing behavior analysts (e.g., BCBAs, BCaBAs, RBTs) and other clinicians with an in-depth introduction to a Progressive Approach to ABA and how it applies to common teaching methods within ABA-based interventions. This includes research and guidelines for implementing a Progressive Approach to ABA, potentially increasing the likelihood of meaningful outcomes for individuals diagnosed with ASD. This will become the guide for practitioners on how to use clinical judgment and in-the-moment assessment across various procedures.
