What Is Applied Behavior Analysis (ABA) Therapy?

How Does ABA Therapy Work?

An ABA treatment plan is designed for each individual person, based on their age, needs, interests, existing skills, and family situation. It’s developed after an ABA-qualified therapist meets, interviews, and observes the person involved. Autism Speaks breaks down the steps of an ABA treatment plan as follows:

Consultation and assessment

A common first step is to identify the client’s or organization’s current skills, goals, needs, and context. A behavior analyst assesses communication, behavior, interactions, environmental conditions, and barriers to the target skill or behavior. Depending on the setting, assessment may occur in a home, school, clinic, workplace, residential program, community setting, or other natural environment.

The assessment may also include interviews with the person receiving services, caregivers, family members, teachers, supervisors, or other support people to gather history, identify strengths, define target skills or behaviors, and understand contextual factors. This information helps shape an individualized plan.

Developing a plan

According to Autism Speaks, using these observations and interviews, the ABA therapist develops a treatment plan that improves upon existing skills and addresses challenging behaviors. Depending on the desired goals or outcomes, the plan may address any of these areas:

• Language and communication skills, including such basic actions as how the person forms sounds and pronounces words
• Academic skills
• Motor skills, either fine or gross
• Social skills
• Self-care, such as cleanliness and grooming habits
• Recreation or play

The treatment plan expands on the above areas as needed, creating steps for each skill area. The steps may include techniques and interventions that are the hallmarks of ABA therapy.

Caregiver training

Although therapy lays the foundation, the treatment plan is typically shared with parents, caregivers, and teachers to provide consistency in daily life. For instance, if a child received different responses to the same behavior from different people, their progress toward a goal behavior could stall or be lost. On the other hand, receiving consistent responses from all the primary adults in a child’s life helps reinforce the desired behavior and increase progress toward the goal.

Frequent evaluation

An ABA therapist collects observations and data to track progress on the client’s or learner’s goals. They determine which strategies and techniques are working and which are not, and then adjust the treatment plan as necessary.

While ABA therapy may be delivered at home, applied behavior analysts may work in homes, schools, clinics, hospitals, and community settings.

ABA Techniques

Autism Speaks, an autism advocacy and services organization, notes that applied behavior analysts primarily rely on two techniques: positive reinforcement and antecedent-behavior-consequence (A-B-C) practice. However, other techniques may also achieve the desired outcomes.

Positive reinforcement

Parents may be familiar with positive reinforcement: it’s a basic understanding that when we receive rewards for certain behaviors, we are more likely to repeat them. The reward may be as simple as praise, small treats like stickers, or privileges such as watching a video or having screen time. Over time, positive reinforcement builds meaningful, lasting change by associating good behavior with desirable outcomes and strengthening skills.

A-B-C practice

A-B-C practice, on the other hand, helps providers understand what happens before and after a behavior so they can teach skills and adjust supports. This type of intervention allows autistic people and their caregivers to avoid the triggers associated with challenging behavior or to more effectively intervene and reduce the outcomes that follow.

Generally, these techniques address behaviors related to socializing or learning, such as communication, reading, academics, dexterity, or occupational competence.

The initials stand for antecedent, behavior, and consequence. The antecedent is whatever comes before and may influence a behavior. That may be a request or statement from another person, stimulation from the environment (such as noise, light, television, or something happening outside), an object (such as a toy or device), or something within, such as a thought or feeling.

The behavior is the response to the antecedent. It may be a verbal response, an emotional response, a non-response, or an action.

And the consequence is what happens after the behavior. For a desired behavior, it may be some form of positive reinforcement. If the behavior is not desired, the response may include withholding reinforcement, adjusting the environment, or using another clinically appropriate strategy.

Negative reinforcement

It’s also important to understand the role that negative reinforcement may play in ABA. This doesn’t mean punishment; it refers to a behavior that causes something negative to go away or end. It’s important to realize that children can also teach themselves negative-reinforcement behaviors. Two examples:

• A child doesn’t like carrots, so he throws a tantrum whenever there are carrots on his plate. This causes his parents to take the carrots away, reinforcing the child: When I throw a tantrum, the carrots are taken away.
• A child who wants to get down from the dinner table learns that when she eats three bites of her vegetables, she’s allowed to get down. In this case, the negative of having to sit at the table is removed when the child eats three bites.

Behavior contracts

Behavior contracts are what they seem: A contract between two people (an ABA therapist and a client, for instance, or a parent and a child) outlining a desired behavior and an agreement about what the reward may be for that behavior. The contract is written, and both people sign it. Example: Every day a child finishes homework without arguing, she receives a gold sticker. When she earns 20 gold stickers, she’s allowed to trade them for a bigger reward: a trip to the park, for instance.

Video modeling

ABA clients—especially visual learners—may benefit from watching videos of the desired behavior in action. Watching a video of children raising their hands to ask questions rather than speaking out of turn may be more effective than simply telling a child what to do. An ABA analyst may watch a video with a child and then recreate that scene with the child, reinforcing the desired behavior.

Components of ABA Therapy

Consultation and assessment allow clients or learners, along with their caregivers, to meet with an applied behavior analyst to discuss the challenges they face and the results they hope to achieve. The analyst may conduct a functional behavior assessment to gauge the person’s behavioral strengths, needs, and goals.

Following the initial observation, the analyst will produce a plan to increase helpful skills and reduce challenging behavior, with specific treatment goals and strategies, usually with the aid of caregivers. Once the plan is mutually established, the analyst will train the caregiver(s) on how to implement it properly, discussing specific tactics to reinforce target skills and reduce challenging behavior.

The last phase of ABA therapy is continuous, as the analyst should conduct ongoing evaluations to ensure the treatment plan is effective and followed, or modified when necessary.

Who Qualifies for ABA Therapy?

Applied behavior analysts work with people from children to adults who want to improve their behavior as it relates to socialization and learning. In particular, analysts may help patients improve their communication, reading, academics, dexterity, or occupational competence. They may also help clients or learners address behavioral goals related to substance use, brain injury, autism spectrum disorder, or other medical conditions.

The best way to tell whether ABA services may be appropriate is through the first component of ABA therapy: consultation and assessment.

Autism Spectrum Disorder (ASD) and ABA Therapy

According to Autism Speaks, autism spectrum disorder (ASD) is characterized by challenges with social skills, repetitive behavior, speech, and nonverbal communication. According to the Centers for Disease Control, autism affects an estimated 1 in 31 children and 1 in 45 adults in the United States today.

Because autism is a spectrum, it manifests differently in different people. Some people with ASD may live entirely independent lives, while others may require significant daily support. Autism may be accompanied by gastrointestinal conditions, seizures, sleep disorders, and mental health challenges such as anxiety, depression, and attention-related issues.

Symptoms typically appear around age two or three, but it may be diagnosed as early as 18 months. Early intervention and individualized services can improve later outcomes; medication may help manage some co-occurring symptoms, but does not treat autism itself.

Symptoms of autism

There are symptoms that can generally be attributed to autism spectrum disorder. Broadly speaking, these are challenges with social skills, repetitive behavior, speech, and nonverbal communication. More specifically, these can be difficulties with spoken language, gestures, and eye contact; challenges recognizing emotions, intentions, and personal space; and repetitive body movements, ritualistic behavior, and extreme interest in narrowly defined subjects.

While some of these symptoms become most noticeable in childhood, signs can appear in children younger than 24 months, including limited facial expressions, lack of eye contact, and little babbling or speaking.

How does ABA therapy help with autism?

According to Autism Speaks, ABA therapy can help autistic people build social skills, improve communication, and reduce challenging behavior, primarily through two techniques: positive reinforcement and antecedent-behavior-consequence practice.

Positive reinforcement encourages desirable behaviors and skills through reward, which, over time, builds meaningful and lasting change. A-B-C practice reduces problematic behavior through analysis of what leads to and results from such behavior, allowing those struggling with autism and their caretakers to avoid triggers or intervene to reduce negative effects.

What Is the Evidence That ABA Works?

ABA therapy focuses on each behavior individually, outlining steps to create preferred behaviors and ways to reinforce them when they occur. With time and consistency, positive behaviors begin to replace problem behaviors.

Applied behavioral analysis has been the subject of decades of research. In 2014, the American Academy of Child and Adolescent Psychiatry said, “ABA techniques have been repeatedly shown to have efficacy for specific problem behaviors, and ABA has been found to be effective as applied to academic tasks, adaptive living skills, communication, social skills and vocational skills.” Autism Speaks says that ABA is an “evidence-based best-practice treatment,” which means it has “passed scientific tests of its usefulness, quality and effectiveness.”

The Centers for Disease Control and Prevention (CDC), the National Institute of Mental Health (NIMH), and the National Institute of Child Health and Human Development have recognized the effectiveness and merit of the ABA process. And the U.S. Surgeon General’s 2001 Report on Mental Health said, “Among the many methods available for treatment and education of people with autism, Applied Behavior Analysis (ABA) has become widely accepted as an effective treatment. Thirty years of research demonstrated the efficacy of applied behavioral methods in reducing inappropriate behavior and in increasing communication, learning, and appropriate social behavior.”

Salaries and Projected Job Growth of ABA Therapists

While the Bureau of Labor Statistics does not have figures on applied behavior analysts in particular, it does track substance abuse, behavioral disorder, and mental health counselors in general. From 2024 to 2034, the BLS expects counseling jobs to grow 17%—great news for anyone looking to become a behavioral analyst.

Counselors may be employed in a variety of settings, detailed in a table below, and earn a median annual salary of $59,190, though compensation may be significantly higher depending on location. Per the BLS, the work environment for substance abuse, behavioral disorder, and mental health counselors:
