ABA therapy focuses on a combination of behavior change and skills acquisition programs that are highly individualized to the child and their needs. Many factors are considered when developing a treatment plan and programs that are both effective and appropriate for achieving the treatment goals. When developing the treatment plan the child's age, assessment results, behavior, and parental concerns are all taken into account. Behavior programs will reduce problem behaviors by teaching and rewarding positive replacement behaviors. Social skills, communication, and daily living skills are always a focus.
