Progressive ABA as it Relates to Individuals Diagnosed With Autism Spectrum Disorder: Recent Advancements in Research and Clinical Practice
Monday, March 1, 2021
1:20 PM–2:10 PM
Area: AUT; Domain: Service Delivery
Chair: Robert K. Ross (Beacon ABA Services)
CE Instructor: Justin Leaf, Ph.D.
Presenting Author: JUSTIN LEAF (Autism Partnership Foundation)

Applied Behavior Analysis (ABA) is a science and, therefore, involves progressive approaches and outcomes. In this presentation we will argue that the spirit and the method of science should be maintained in order to avoid reductionist procedures, stifled innovation, and rote, unresponsive protocols that become increasingly removed from meaningful progress for individuals diagnosed with autism spectrum disorder (ASD). We describe this approach as progressive. In a progressive ABA approach, the therapist employs a structured yet flexible process, which is contingent upon and responsive to child progress. We will describe progressive ABA and provide rationales for both the substance and intent of ABA as a progressive scientific method for improving conditions of social relevance for individuals with ASD. We will provide the audience with data from recent studies on how Progressive ABA can be implemented to individuals diagnosed with ASD; as well as our findings in clinical practice.

Instruction Level: Intermediate
Target Audience:

Board certified behavior analysts; licensed psychologists; graduate students. 

Learning Objectives: At the conclusion of the presentation, participants will be able to: (1) identify and describe at least five factors that go into clinical judgment; (2) identify and describe at least two findings from the research on the effects of Progressive ABA as it relates to individuals diagnosed with ASD; (3) compare and contrast Progressive ABA to conventional ABA across at least three dimensions.
