DRA in ABA: Reinforce a desirable alternative behavior rather than the target

Differential Reinforcement of Alternative Behavior (DRA) focuses reinforcement on a replacement behavior that serves the same function as the problem behavior. The learner is encouraged to emit the desirable alternative, while the target behavior is not reinforced. This helps reduce undesired actions.

DRA: The art of swapping a problem with a better fit

If you’re studying Applied Behavior Analysis, you’ve probably heard of DRA—Differential Reinforcement of a Desirable Alternative Behavior. It’s one of those ideas that makes sense the moment you see it in action: when a learner has a tough time and a challenging behavior pops up, you don’t punish the moment you see the problem. Instead, you reinforce something better—an alternative behavior that’s appropriate to emit in that setting and serves the same purpose as the unwanted behavior. Let’s untangle what that means in real life and why it works so well.

What DRA is really about

Here’s the core thing to remember: DRA isn’t about suppressing a behavior by sheer force. It’s about guiding a learner toward a different, more adaptive way to meet the same need. Think of it as offering a better tool that still gets the job done. If a learner snaps their fingers to access attention, you don’t just stop the snapping; you reinforce a replacement behavior, like raising a hand or approaching in a socially acceptable way, whenever that replacement behavior happens.

That distinction matters because it explains why DRA tends to be kinder and more effective than blunt strategies. You’re not arguing with the learner over what they can’t do; you’re teaching them what they can do instead, with a positive nudge when they do it.

A quick correction to a common mix-up

In your materials, you may have seen the description that “reinforcement is delivered for a desirable alternative behavior.” That’s exactly right. The point isn’t to reward something unrelated to the problem. It’s to reward something that can function as a replacement and is useful in the current setting. If you reinforce an unrelated behavior, it won’t reliably reduce the target behavior because it doesn’t take over the same role in the environment.

So, to be crystal clear: under DRA, reinforcement goes to the desirable alternative behavior, not to the problem behavior and not to something that’s unrelated to the issue. That connection—the replacement behavior serving the same function—is what makes DRA work.

Why choosing the right replacement is the tricky bit

The heart of DRA is function-based thinking. You want an alternative that serves the same purpose as the problem behavior. If the learner’s hitting is aimed at gaining attention, the replacement should be a socially acceptable way to get attention that’s available in that moment. If the function is escape or avoidance, the replacement might be a brief, appropriate way to request a break or a different activity. The match between function and replacement keeps the new behavior relevant and sustainable.

Sometimes this means a few iterations. You test a candidate replacement, observe how it’s used, and adjust. Maybe the initial alternative works only some of the time, or it’s not as easy for the learner to emit in the moment. That’s okay—adaptive teaching is often iterative. You tweak prompts, adjust reinforcement schedules, or simplify the replacement until it becomes a reliable option.

Practical steps to implement DRA

Here’s a straightforward way to put DRA into practice, without turning it into a maze.

• Identify the function of the target behavior: What need is the learner trying to meet? Attention? Escape? Access to preferred items? Knowing the why helps you pick a suitable replacement.

• Choose a replacement behavior: Pick something that serves the same function but is appropriate in the setting. It should be observable, measurable, and teachable.

• Define clear criteria for reinforcement: Decide exactly what counts as “the learner did the replacement behavior.” Break it down into observable steps if needed.

• Reinforce consistently, at least initially: When the learner emits the replacement, deliver reinforcement promptly. Early consistency helps the replacement take hold faster.

• Fade prompts over time: Start with more support if needed, then gradually reduce prompts as the learner owns the behavior.

• Monitor and adjust: If the target behavior persists, revisit the function and the replacement choice. If the replacement is not catching on, consider a different option that still meets the same need.

• Plan for generalization: Practice the replacement in different adults, settings, and times to help it stick across the learner’s day.

A practical example to make it click

Imagine a child who cries loudly to avoid doing chores. The crying function here is escape—getting a break from the task. A DRA approach would be to give the child a clear, acceptable way to request a break—perhaps a “break card” or a brief, approved verbal cue like “Take a short break, please.” When the child uses the break request, you reinforce it with a short, well-timed break. Over time, the child learns that asking for a break is a reliable way to momentarily pause, which reduces the urge to cry.

Meanwhile, you don’t reinforce the crying at all. If the child cries, the break request isn’t earned and the break is not granted as a consequence of the outburst. The focus stays on teaching and strengthening the replacement, not on punishing the problem behavior.

Some nuanced moves that help DRA work smoothly

• Align the alternative with the environment: The replacement should be feasible in the daily routine. If it’s too hard to do in a busy classroom, you’re setting the learner up for frustration rather than success.

• Start with high-quality reinforcement: Early on, the reward needs to be meaningful enough to compete with the reinforcement the problem behavior currently provides. It could be social praise, access to a preferred activity, or a tangible item—whatever lands best with the learner.

• Keep the reinforcement sparse but meaningful as the replacement gains traction: You don’t want to create a dependency on constant rewards, but you do want enough reinforcement to encourage the new behavior.

• Consider gentle fading: As the replacement behavior becomes more reliable, you can shift from continuous reinforcement to a thinning schedule. The goal is natural motivation and independence.

• Pair the replacement with the function in other ways: For instance, if the function is attention, the replacement could be a moment of focused adult attention when the replacement is used correctly, then the attention is gradually reduced as the learner becomes more autonomous.

What DRA isn’t

To keep expectations realistic, here are a few limitations to keep in mind.

• DRA is not a magic wand. It won’t fix everything overnight. It’s a deliberate strategy that needs consistency, data, and thoughtful selection of replacements.

• It’s not about “replacing every behavior instantly.” Some learners benefit from a combination of strategies, including Differential Reinforcement of Other Behavior (DRO) or other reinforcement-based approaches, depending on the situation.

• It isn’t about punishing the problem behavior. The goal is to shift maintenance to the replacement and to lessen the pull of the undesired behavior over time.

Where these ideas connect to bigger picture concepts

DRA sits alongside a spectrum of differential reinforcement strategies. You might also hear about DRO (reinforcement for absence of the problem behavior for a set interval) or DRI (Differential Reinforcement of Incompatible Behavior), which is about reinforcing a behavior that cannot occur simultaneously with the problem behavior. Each tool has a distinct role, but they share a common thread: use reinforcement to shape behavior in a positive, functional direction.

A little philosophy of teaching

One reason DRA resonates with many learners and teachers is its human-centered feel. It recognizes that behavior is communication. When someone emits a behavior, they’re sending a signal about what they need. By offering a viable, desirable alternative, you’re meeting that need in a healthier, socially appropriate way. It’s not about silencing the person; it’s about guiding them toward a more flexible, versatile way to get what they want.

A note on measurement and reflection

As you apply DRA, you’ll want to track a few things. Frequency of the replacement behavior is the clearest indicator that the strategy is taking hold. You can also watch for reductions in the target behavior over time, though that’s a slower signal. Keep notes on the context, prompts used, and the type of reinforcement delivered. With data in hand, you’ll spot patterns—what’s working, what’s not, and where to adjust.

The road ahead is practical and hopeful

DRA isn’t flashy, and it isn’t a one-size-fits-all solution, but it’s deeply practical. When done with care, it creates smoother interactions, clearer communication, and more predictable outcomes. For learners, it means a clearer path to getting what they need without stepping into the same old problem behaviors. For teachers, it’s a reliable framework that blends empathy with effectiveness.

If you’re exploring this approach, a good next step is to map out a couple of common problem behaviors you see and brainstorm plausible replacements that would serve the same function. Start with simple, observable targets and plan a few weeks of consistent reinforcement. You’ll likely find that the replacement behaviors, once learned, become genuine tools in the learner’s daily life—skills they can choose, adjust, and rely on.

In the end, DRA is about choice and competence. It’s about giving learners better options, and giving us a clearer lens to see what they’re trying to communicate. When you see it click—the replacement behavior appears, the function is met, and the learner moves forward with a bit more confidence—you’ll know you’re on the right track. And that’s the kind of progress that sticks, day after day, in classrooms and beyond.
