The ABCs of ABA: A Parent’s Guide to Applied Behavior Analysis

Applied Behavior Analysis (ABA) is a type of therapy often used to improve or change specific behaviors. It’s particularly beneficial for children with autism and other developmental disorders. As a parent, understanding ABA can help you support your child’s development and communicate effectively with therapists. This guide will walk you through the basics of ABA.

Understanding Applied Behavior Analysis

ABA is a scientific approach to understanding behavior. It’s based on the idea that behaviors are influenced by what happens before them (antecedents) and what happens after them (consequences). By manipulating these antecedents and consequences, ABA aims to increase positive behaviors and decrease negative ones.

ABA therapy is highly individualized and can be used to improve a wide range of behaviors, including social skills, communication, reading, and adaptive living skills like fine motor dexterity, hygiene, grooming, domestic capabilities, punctuality, and job competence.

The ABCs of Applied Behavior Analysis (ABA)

The ABCs of ABA refer to the Antecedent, Behavior, and Consequence, which are the three key factors in the behavior analysis:


The antecedent is what happens right before the behavior. It can be an event, an environment, or a physical or verbal interaction that triggers the behavior.


The behavior is the action that is the focus of the analysis. It’s the specific behavior that you want to change or improve.


The consequence is what happens right after the behavior. It can either encourage the behavior to happen again (reinforcement) or discourage it (punishment).

Understanding these three components can help you identify why a behavior is happening and how to change it.

The Role of Reinforcement

Reinforcement is a key concept in ABA. It involves providing a consequence that will increase the likelihood of a behavior happening again. There are two types of reinforcement:

Positive Reinforcement

Positive reinforcement involves adding something to the situation to encourage the behavior. This could be praise, a toy, or a favorite activity.

Negative Reinforcement

Negative reinforcement involves removing something from the situation to encourage the behavior. This could be taking away a disliked task or stopping an annoying noise.

Reinforcement is typically more effective than punishment in changing behavior, and it’s a key tool in ABA therapy.

The Role of Data in ABA

Data collection is a crucial part of ABA. Therapists will collect data on the antecedents, behaviors, and consequences to understand the patterns and make informed decisions about treatment. This data can also be used to track progress and adjust the therapy as needed.

As a parent, you can also collect data to support the therapy. This could involve noting down when and where certain behaviors occur, what triggers them, and what seems to help.

Finding an Applied Behavior Analysis ABA Therapist

Finding the right ABA therapist for your child is crucial. Look for a Board Certified Behavior Analyst (BCBA) or a therapist under the supervision of a BCBA. They should have experience working with children with similar needs to your child.

When choosing a therapist, consider their approach, their communication style, and how they involve parents in the therapy. It’s important to find a therapist who is a good fit for your child and your family.

Supporting Your Child’s ABA Therapy

As a parent, you play a crucial role in your child’s ABA therapy. You can support the therapy by reinforcing the same behaviors at home, collecting data, and communicating regularly with the therapist.

Remember, consistency is key inABA therapy. The more consistent you are in reinforcing the behaviors, the more effective the therapy will be.


ABA can be a powerful tool for supporting your child’s development. By understanding the basics of ABA, you can better support your child and work effectively with their therapist. Remember, every child is unique, and what works for one child may not work for another. ABA therapy should be individualized to meet your child’s specific needs. With patience, consistency, and the right support, ABA can help your child develop important skills and behaviors.
