The Difference Between RDI & ABA

RDI and ABA refer to two different treatments for autism, a developmental disorder that can manifest in before a child turns three years old. According to PubMed Health, the causes of autism are still under study, but such factors as diet, mercury poisoning, sensitivity to vaccines and even genetics are suspected. Neurological issuescauses and chromosomal anomalies occur more frequently in families with autism than in the general population. ABA , which stands for Applied Behavior Analysis, and RDI, which stands for Relationship Development Intervention, both can treat the condition, but ABA has a significantly longer track record of effective results.

  1. ABA -- Philosophy and Background

    • The philosophy behind ABA is that people will repeat behaviors for which they receive rewards. If their behavior is ignored, they will stop doing it. In use since the 1960's, ABA has a lengthy history of success. As of 2011, the American Academy of Pediatrics, the American Medical Association and the U.S. Surgeon General all endorse ABA for autism.

    How ABA Works

    • Initially, a therapist will spend up to 40 hours a week with a new patient, with the goal of putting together a thorough behavior profile. Using that profile, the therapist will develop goals to help with socializiation, communication and academics. Those goals will lead to a specific progression to move the child forward. Then, the therapist will use that progression to instill different skills in the patient.

    RDI -- Philosophy and Background

    • As of 2011, RDI is a fairly new treatment system for autism. Its focus is teaching patients how to have social relationships with others, beginning with a child's parents. While it does not have the level of anecdotal support that ABA does, early studies by the therapy's creators, Steven Gutstein and Rachelle Sheely, purport to show promise.

    How RDI Works

    • A neurologist will perform an initial assessment of the child. Parents go through a training seminar about the basic principles and techniques associated with RDI, and a consultant sets up an individualized plan of action for the patient. Parents record sessions with the child and then send in those videos and answer questionnaires, and the consultant assesses progress. Because parents are the first coaches in RDI, there is a significantly higher level of family responsibility for the outcomes.
