A person’s ability to communicate lies within the foundation for their personal connections, confidence, and community participation, among other things. Children and individuals with autism often face challenges in these areas, but it’s not because of a lack of motivation; it’s because autistic people process social information differently and sometimes less intuitively than their neurotypical peers. That’s where intentional, structured teaching becomes helpful.

Applied Behavior Analysis (ABA) is one of the most widely used and researched approaches to support the development of social skills, particularly for autistic children. But how exactly does it work, and what does the science say? Let’s break down what the science says!

What Is ABA Therapy, Really?

ABA is a science-based therapeutic approach that looks at the environment’s influence on behavior and teaches new skills through systematic instruction and reinforcement. Rather than relying on assumptions, ABA uses data and observation to figure out what’s helping and what isn’t.

Many people associate ABA with discrete trials (structured teaching steps), but ABA strategies also include Natural Environment Teaching (NET), behavioral skills training, modeling, social stories, and group social skills sessions – all of which can be powerful tools for building social competence.

What Research Shows About ABA and Social Skills

Statistically Significant Improvements

Recent research underscores that ABA can improve social and communicative skills in children with autism. One controlled study found that children who participated in structured ABA sessions showed significantly higher social and communicative functioning than peers who didn’t receive the program, which held up in statistical analysis (Du et al, 2024).

Another study focused specifically on a social skills group built with progressive ABA principles. Participants in the treatment group showed significant improvements in social behaviors compared to a waitlist control group, and these gains were maintained for up to 32 weeks after the program ended (Leaf et al, 2017).

This research suggests that ABA is not just teaching isolated skills in a vacuum. It helps people function better in real social contexts and retain those skills over time.

How ABA Targets Social Skills in Practical Ways

1. Breaking Skills Into Teachable Steps

Many common social interactions are actually quite complex. Think about greeting a peer: a child has to recognize a social partner, decide what to say, monitor body language, and adjust based on the other person’s response, all in real time. ABA breaks down these behaviors into smaller, observable steps and teaches them in ways that match a learner’s current ability.

For instance, a therapist might start by reinforcing eye contact paired with greeting words (“Hi!”), and then gradually shape the behavior toward more natural and spontaneous interactions.

2. Reinforcement That Makes Sense

Reinforcement isn’t bribes or rewards – it’s meaningful motivation. ABA practitioners work closely with individuals and families to understand what truly matters to them. When a child uses a target social behavior (like asking to play), immediate reinforcement helps the brain connect that behavior with a positive outcome, increasing the likelihood it will occur again.

The principle of positive reinforcement is at the heart of measurable change in social communication!

3. Real-World Practice and Generalization

It’s one thing to say “hello” in a therapy room; it’s another to do so on the playground. ABA doesn’t stop at skill acquisition. Therapists work on generalization, meaning the ability to use learned skills across settings, with different people, and in real life. This often involves practicing during playdates, school, community outings, and family routines.

Generalization is the transfer of learned skills to everyday contexts and is a core goal of meaningful ABA therapy.

4. Peer-Related Social Competence

A large body of research shows that social skills interventions – especially those that involve peers – make a difference. Peer-mediated and school-based social skills programs produce moderate to strong effects on social competence in children with ASD. This means that when typically developing peers are intentionally included in structured activities, children with autism practice and internalize social behaviors in natural contexts.

Social STEPS

Here at STEPS Behavioral Health, we offer an evening social skills program called Social STEPS. We host various social skills groups for children ages 5 and up, Monday – Thursday at our Pikesville and Towson clinics. The groups meet weekly, allowing the children to have peer interactions and support from our clinical staff. Groups will use various, often play-based strategies to practice specific skills, and parents are given training as well, so that they can continue to practice targeted skills at home.

A Note on Strengths and Limitations

It’s important to approach any therapy with a balanced mind. While many studies support the positive impact of ABA on social skills, experts also emphasize that:

• Effectiveness varies by individual: No two learners are the same, and ABA programs should always be individualized, which is something we prioritize here at STEPS.

• Integration with other approaches helps: Combining behavioral strategies with communication supports, family coaching, and community inclusion will yield the best outcomes (Esposito et al, 2025).

What Families Often Notice

Parents and caregivers who engage in structured, research-informed ABA often observe changes like:

• Increased shared attention and body positioning towards communicative partners
• More frequent and appropriate initiations with peers
• Better turn-taking and conversational skills
• Greater comfort and confidence in group activities
• More successful play interactions

These gains can make school and social settings more enjoyable, and they often translate into deeper friendships and a stronger sense of belonging.

Overall…

Social skills aren’t innate for everyone, and that’s okay! For many children and individuals with autism, social learning happens best with structured support, active practice, and reinforcement that respects how they learn. ABA offers a scientific framework for understanding behaviors and teaching socially meaningful skills in ways that are measurable, personalized, and rooted in real life.

By breaking complex interactions into achievable steps, reinforcing progress, and helping learners generalize skills across settings, ABA has helped thousands of individuals grow their social capacity and confidence. At STEPS, we know that with intentional and well-rounded support, social development is more than possible.
