Applied Behavior Analysis (ABA) is the treatment approach identified across the research literature as showing the most evidence of positive impact on child developmental trajectory.
Behavior Analysis is the scientific study of behavior. Applied behavior analysis (ABA) is the application of the principles of learning and motivation from behavior analysis, and the procedures and technology derived from those principles, to the solution of problems of social significance.
An ABA program uses a systematic teaching approach that involves breaking skills down into small, easy-to-learn steps. Praise or other rewards are used to motivate the child. Multiple opportunities are provided to practice each skill and progress is continuously measured to make an informed decision regarding adjustments to the treatment plan for the child. ABA programs are specifically developed and designed to meet the developmental needs of each child.
Many people are familiar with the use of ABA in treating autism through an intensive comprehensive treatment program of 20-40 hours per week of direct therapy for two years or longer and with the goal of impacting all areas of development. However, ABA can be conducted across shorter periods of time as well as across the person's lifetime (e.g., a teenager who needs to be desensitized to going to the dentist). The level and intensity of programming should be driven by the child's needs.
A wide variety of ABA techniques have been developed for building useful skills in people with autism--from toddlers through adulthood. Some of these techniques include reinforcement, shaping, chaining, modeling, prompting, fading, discrimination learning, and task analysis using teaching formats such as discrete trial teaching. ABA can be used to understand and teach language, treat challenging behavior, teach daily living skills, and increase skill acquisition in other developmental areas.
ABA therapy can be provided in many settings, including home, school, clinic, or community locations the person frequents. The goals and treatment plan used in these settings may differ. In an educational setting, the focus is on teaching and achieving educational goals aligned with state curriculum standards. When services are provided in clinics, community and home settings, the focus is on teaching functional skills and generalization of skills learned in clinical and educational settings in the natural environment.
