Introduction to ABA and Autism Treatment

Of the myriad of approaches to the treatment of autism spectrum disorders, Applied Behaviour Analysis (ABA) has the most research support. It is not perfect, and its imperfection is highlighted by the inadequate training of many, if not most of its practitioners. Autism is a burgeoning condition—in some locations, it is estimated to affect one in every seventy-five children—and the numbers of instructor-therapists required to meet their need for treatment is ensuring that many enter the field with inadequate training. Of course, lack of training is not unique to practitioners of ABA; the entire field is struggling to keep up to the demand for services.

A related and perhaps as serious a problem is the narrowness of vision that most practitioners bring to the enterprise. ABA has been defined as the process of systematically applying interventions based upon the principles of learning theory to improve socially significant behaviors to a meaningful degree, and to demonstrate that the interventions employed are responsible for the improvement in behavior (Baer, Wolf, and Risley, 1968). Being based on the past hundred years of research into how learning works, ABA has universal application—it can be applied to any developmental issue. Unfortunately, while any concept can be defined in behavioral terms, you only have to ask yourself, What will I use as an indicator of _______? It tends to get applied primarily to those developmental issues that are easiest to define in behavioral terms.

On the other hand, most non-ABA approaches have relatively little scientific support. This brief introduction to teaching children with autism is intended to serve as a primer for both instructor-therapists and parents alike. Hopefully, it will also move the field beyond the narrow focus that it has enjoyed for the past few decades.
