The Behavior Analyst Certification Board (BACB) was established in 1998 and provides internationally recognized certification in the field of Applied Behavior Analysis (ABA) at the High School (Registered Behavior Technician™; RBT®), Bachelor’s (Board Certified Assistant Behavior Analyst®; BCaB®) and Master’s (Board Certified Behavior Analyst®; BCBA®) level. There are currently more than 36,000 behavior analysts and over 55,000 behavior technicians certified in over 89 countries. Historically Applied Behavior Analysis is best known for its application in the treatment of individuals with autism and developmental disabilities; however the field has broadened to many other areas including the care and treatment of people who have sustained an acquired brain injury. This presentation will describe the role of the Behavior Analyst as part of the inter-disciplinary team in the acute rehab setting. Participants will learn from real-life examples of the utility of the BCBA® and ABA, including specific benefits to patients in the areas of skill acquisition, reduction of maladaptive behaviors, improved empiricism, and their overall impact on care and treatment. Practical advice, case illustrations and useful resources will also be provided.
