Applied Behavior Analysis (ABA) therapy is a structured and evidence-based approach used to improve specific behaviors and skills in individuals, particularly those with autism spectrum disorder (ASD). It is grounded in the principles of behaviorism, focusing on how behavior works, how it is affected by the environment, and how learning occurs. ABA therapy involves breaking down complex skills into smaller, manageable steps and using positive reinforcement to encourage desired behaviors while reducing unwanted or challenging behaviors. Therapists work one-on-one with the individual in a highly structured setting, often tailoring interventions to target communication, social skills, attention, learning readiness, and self-care. The therapy is data-driven, meaning progress is continually monitored and strategies are adjusted based on the individual’s needs. ABA therapy is widely recognized for its effectiveness in helping individuals with autism lead more independent and socially engaged lives.
