Understanding Behavior Reduction Techniques in ABA Therapy: What You Need to Know

Applied Behavior Analysis (ABA) therapy is a widely used and scientifically validated approach to helping individuals with autism spectrum disorder (ASD) and other developmental disabilities improve their skills and manage challenging behaviors. One important aspect of ABA therapy is the use of behavior reduction techniques, which are designed to decrease the frequency or intensity of inappropriate or harmful behaviors. This article will explore what you should know about behavior reduction techniques used by ABA therapists.

Identifying the Function of Behavior 

Before implementing any behavior reduction techniques, ABA therapists first conduct a thorough assessment to identify the function or purpose of the challenging behavior. This process, known as a functional behavior assessment (FBA), involves observing the individual in various settings, collecting data on the antecedents (events or stimuli that occur before the behavior) and consequences (events that follow the behavior), and interviewing parents, caregivers, and other relevant stakeholders.

Understanding the function of the behavior is crucial because it helps the therapist develop an effective intervention plan that addresses the underlying reasons for the behavior, rather than just the behavior itself. Common functions of behavior include:

  • Escape or avoidance of unpleasant tasks or situations
  • Attention-seeking
  • Access to desired items or activities
  • Sensory stimulation or self-regulation

Positive Reinforcement and Skill-Building 

One of the core principles of ABA therapy is the use of positive reinforcement to encourage and strengthen appropriate behaviors. When working on behavior reduction, ABA therapists often combine this approach with teaching new skills that serve as functional alternatives to the challenging behavior.

For example, if a child engages in tantrums to escape a difficult task, the therapist may teach the child to request a break or ask for help using appropriate communication skills. By reinforcing these alternative behaviors and providing the child with the necessary tools to cope with challenging situations, the therapist can help reduce the frequency and intensity of the tantrums over time.

Antecedent Interventions 

Antecedent interventions are strategies that focus on modifying the environment or events that occur before the challenging behavior, in order to prevent the behavior from occurring in the first place. These interventions may include:

  • Modifying the environment: Removing or minimizing triggers that may provoke the challenging behavior, such as loud noises or crowded spaces.
  • Providing choices: Offering the individual a choice between two or more acceptable options, giving them a sense of control and reducing the likelihood of resistance or challenging behavior.
  • Priming: Preparing the individual for upcoming activities or transitions by providing clear expectations, visual schedules, or social stories.
  • Noncontingent reinforcement: Providing the individual with access to preferred items or activities on a fixed schedule, regardless of their behavior, to reduce the motivation to engage in challenging behaviors to obtain these reinforcers.

Consequence-Based Interventions 

In some cases, ABA therapists may use consequence-based interventions to reduce challenging behaviors. These interventions focus on modifying the events that occur after the behavior, in order to decrease the likelihood of the behavior recurring in the future. Common consequence-based interventions include:

  • Extinction: Withholding the reinforcement that maintains the challenging behavior, so that the behavior no longer serves its intended function and eventually decreases in frequency.
  • Differential reinforcement: Reinforcing alternative or incompatible behaviors while withholding reinforcement for the challenging behavior.
  • Response cost: Removing a specified amount of a reinforcer (e.g., tokens or points) contingent upon the occurrence of the challenging behavior, to discourage the individual from engaging in the behavior.

It is important to note that consequence-based interventions should be used judiciously and only under the guidance of a qualified ABA therapist, as they can have unintended side effects if not implemented correctly.

Monitoring and Adjusting Interventions 

As with all aspects of ABA therapy, behavior reduction techniques require ongoing monitoring and adjustment to ensure their effectiveness. ABA therapists continuously collect data on the individual’s progress and use this information to make data-driven decisions about whether to continue, modify, or discontinue specific interventions.

Regular communication and collaboration with parents, caregivers, and other professionals involved in the individual’s care are also essential for ensuring that behavior reduction strategies are consistently implemented across settings and that any concerns or challenges are promptly addressed.


Behavior reduction techniques are a critical component of ABA therapy, aimed at helping individuals with ASD and other developmental disabilities manage challenging behaviors and improve their overall quality of life. By understanding the functions of behavior, using positive reinforcement and skill-building strategies, implementing antecedent and consequence-based interventions, and continuously monitoring progress, ABA therapists can effectively support individuals in reducing inappropriate or harmful behaviors and developing more adaptive skills. If you are considering ABA therapy for yourself or a loved one, it is essential to work with a qualified and BCBA therapist who can develop a personalized intervention plan that meets your unique needs and goals.
