Introduction Over the course of the past decade, the field of Applied Behavior Analysis (ABA) has become synonymous in the eyes of many parents, teachers and clinicians from other disciplines with treatment of autism. Many professionals in ABA do not fully welcome a narrow view of this applied science. However, it can be argued that this is partially a very good thing for our field. The perception of ABA as the most effective treatment for children with Autism Spectrum Disorders has come about as a result of the demonstrated effectiveness of the application of the principles and procedures consistent with the science of ABA (Lovaas, 1987; NYS DPH EIP, 1999: NRC, 2001). The lack of the identification of ABA as the most empirically effective treatment for other areas (e.g., psychological and emotional disorders), for which is it often applied, may stem from an absence of such data and formal application of our technology. Rather than lament the over identification of ABA with autism treatment, the more adaptive response would be to conduct the kind of empirical studies in the areas of psychological and emotional disorders that has served to bring ABA prominence in autism treatment.
