Differential Reinforcement of Other Behavior (DRO) Explained
As an ABA clinician working with families at Blue Jay ABA, I’m often asked to break down the strategies we use into something practical and easy to understand.
One term that comes up frequently is DRO ABA—and while it may sound technical, it’s actually one of the most approachable and effective tools we use to reduce challenging behaviors.
In this guide, I’ll explain what DRO really means, how I use it in sessions, and what it looks like in real life.
What Does DRO Mean in ABA?
Before diving into the details, it helps to understand that ABA strategies are often built around reinforcement—what we encourage tends to grow. DRO is unique because it focuses on reinforcing the absence of a behavior rather than a specific action.
Breaking Down the Acronym
DRO stands for Differential Reinforcement of Other Behavior.
In simple terms, DRO ABA means reinforcing a child when a specific problem behavior does not occur during a set period of time.
The Core Idea Behind DRO
Instead of correcting or reacting to unwanted behavior, we:
- Monitor for when the behavior is absent
- Deliver reinforcement during those successful moments
This creates a positive cycle where the child begins to associate success with rewards.
How DRO Works in ABA Therapy
To really understand DRO ABA, you have to see how structured it is behind the scenes. When I implement DRO in a session, there’s a clear plan guiding each step—not just spontaneous praise.
Step 1: Identify the Target Behavior
I start by clearly defining what we’re reducing. Examples include:
- Hitting
- Screaming
- Interrupting
Specificity is critical—everyone on the team needs to measure the same behavior.
Step 2: Set a Time Interval
Next, I choose an interval based on the child’s current ability:
- Short intervals (1–2 minutes) for frequent behaviors
- Longer intervals (5+ minutes) as progress is made
The goal is to set the child up for success early on.
Step 3: Deliver Reinforcement
If the behavior does not occur during the interval:
- I immediately provide praise or a reward
- Reinforcement is meaningful and individualized
Step 4: Reset if Needed
If the behavior occurs:
- The interval resets
- No reinforcement is delivered
Consistency here is what makes DROA ABA effective.
Why We Use DRO in ABA
There are many behavior strategies in ABA, but DRO is often one of the first I introduce. That’s because it strikes a balance between simplicity and effectiveness.
A Positive, Non-Punitive Approach
DRO focuses on:
- Reinforcing success
- Reducing attention to negative behavior
- Creating a supportive learning environment
It avoids punishment and instead builds positive habits.
When DRO Is Most Useful
In my clinical work, I typically use DROA ABA when:
- A behavior happens frequently
- A replacement skill hasn’t been established yet
- We need a quick, structured intervention
Backed by ABA Principles
Like all ABA strategies, DRO is grounded in behavioral science:
- Reinforced behaviors increase
- Non-reinforced behaviors decrease
Real-Life Examples of DRO ABA
Understanding the concept is helpful—but seeing it in action is where it really clicks. These are simplified versions of cases I’ve worked on (with details changed for privacy).
Example 1: Reducing Tantrums
The Situation
A child engages in screaming during transitions between activities.
The DRO Plan
- Start with a 2-minute interval
- No screaming = immediate reward
The Outcome
We gradually increased the interval, and transitions became significantly smoother.
Example 2: Decreasing Classroom Interruptions
The Situation
A student frequently interrupts during group instruction.
The DRO Plan
- 5-minute intervals without interrupting
- Earn tokens for each successful interval
The Outcome
The student improved in waiting their turn and participating appropriately.
Example 3: Reducing Aggression
The Situation
A child hits peers during playtime.
The DRO Plan
- Reinforce every 3 minutes of safe behavior
- Increase expectations over time
The Outcome
Aggressive behaviors decreased, and appropriate play increased.
DRO vs Other ABA Strategies
DRO doesn’t exist in isolation—it’s part of a broader set of reinforcement strategies. Understanding how it compares helps parents see when and why we use it.
DRO vs DRA (Alternative Behavior)
- DRO: Reinforces absence of behavior
- DRA: Reinforces a specific alternative behavior
DRO vs DRI (Incompatible Behavior)
- DRO: Any behavior except the target is acceptable
- DRI: Reinforces behaviors that make the problem behavior impossible
Why I Often Start With DRO
In many cases, I begin with DROA ABA because:
- It’s simple to implement
- It builds early success
- It doesn’t require teaching a new skill immediately
Benefits of Using DRO ABA
From both a clinical and family perspective, DRO offers several meaningful advantages. It’s one of those strategies that works well because it’s both structured and flexible.
Easy for Parents to Learn
DRO is:
- Straightforward
- Easy to explain
- Practical for daily routines
Flexible Across Settings
It can be used in:
- Homes
- Schools
- Community settings
Builds Positive Momentum
Small successes lead to:
- Increased confidence
- Better engagement
- Long-term behavior change
Important Considerations When Using DRO
Like any intervention, DRO works best when applied thoughtfully. There are a few important factors I always keep in mind when designing a plan.
Always Understand the Function First
Before implementing DRO ABA, I conduct an assessment to understand why the behavior is happening.
Watch for Other Behaviors
Because we’re reinforcing the absence of one behavior, we need to ensure:
- We’re not accidentally reinforcing another undesired behavior
Combine With Skill Building
DRO is most effective when paired with:
- Communication training
- Social skills development
- Emotional regulation strategies
How DRO Fits Into In-Home ABA Therapy
One of the most effective ways to implement DRO is in the child’s natural environment. That’s where behavior happens most authentically—and where meaningful change occurs.
Real-Life Application Matters
In-home therapy allows us to:
- Apply DRO during real routines
- Practice during actual challenges
- Reinforce meaningful behaviors
Parent Coaching Is Essential
At Blue Jay ABA, I work closely with parents to:
- Model DRO strategies
- Provide real-time feedback
- Adjust plans as needed

Final Thoughts on DRO ABA
DRO is one of those strategies that proves you don’t need something complicated to make a big impact. When used correctly, it creates more opportunities for children to succeed—and that’s always the goal.
Why It Works
It works because it:
- Focuses on positive reinforcement
- Encourages success
- Builds consistency over time
My Experience as a Clinician
I’ve seen DROA ABA
- Reduce challenging behaviors
- Improve family routines
- Increase independence
When implemented consistently and paired with good clinical judgment, DRO becomes more than just a technique—it becomes a pathway to meaningful progress.
FAQs
How is DRO different from DRA?
DRO reinforces the absence of a behavior, while DRA reinforces a specific alternative behavior (like asking for help instead of yelling).
Is DRO considered punishment?
No. DRO is a reinforcement-based strategy. It focuses on rewarding appropriate behavior rather than punishing inappropriate behavior.
How long should DRO intervals be?
It depends on the child and the behavior. I usually start with very short intervals to ensure success, then gradually increase the duration.
Can parents use DRO at home?
Absolutely. In fact, I regularly coach parents to use dro aba strategies during daily routines. It’s one of the most practical tools for home use.
