Motivational Interviewing in ABA: A Practical Guide

Motivational interviewing is a way of talking that helps people change. Instead of telling someone what to do, you guide them. You ask questions and listen closely. The person then reaches the choice on their own.

This skill matters to BCBAs, RBTs, teachers, and parents. Much of our work depends on caregiver buy-in. People resist being told to change. They lean in when the idea feels like theirs. That is the heart of motivational interviewing, or MI.

Why self-made conclusions stick#

Matt Harrington sums up the core idea in one line. Change lasts when a person arrives at it themselves. Pushing harder often makes people push back. Guiding gently helps them own the decision.

The concept of motivational interviewing is that people are more willing to change when they come to the conclusion themselves. From the talk — Matt Harrington

This flips a common habit for many clinicians. We love to explain and advise. MI asks us to slow down and draw the answer out. The caregiver does more of the talking and more of the deciding.

The core skills of MI#

Matt breaks MI into four moves you can practice. You ask open-ended questions that invite more than a yes. You affirm effort to reinforce change. You listen more than you speak. Then you summarize so everyone leaves on the same page.

Open-ended questions, affirmations, that are reinforcing effort and reinforcing change behavior, reflective listening, so you are listening more than you are responding and actually hearing versus trying to see your conversation. And then summarizing, making sure that everyone's on the same page before you leave. From the talk — Matt Harrington

If four skills feel like a lot, Matt names the two that matter most. Open-ended questions and reflective listening carry most of the weight. Master those two first. The rest will follow.

If you take one thing away from this presentation, take away open-ended questions and reflective listening. From the talk — Matt Harrington

Reflective listening means saying back what you heard. It shows the caregiver they were understood. That felt-understanding is what lowers a defensive wall.

Using MI to repair a weak alliance#

MI shines when trust with a caregiver has frayed. A parent who feels judged will resist your plans. Lecturing them makes the gap wider. MI rebuilds the bond by putting their voice first.

You start with a question, not a directive. You reflect their worry before you offer a next step. You affirm the effort they are already making. Slowly, the caregiver moves from pushing back to leaning in.

This is why MI is a top tool for caregiver training. It turns a tense meeting into a shared plan. The parent leaves feeling heard, not managed. That feeling keeps them engaged for the long haul.

MI in assessment and across teams#

MI is not only for tense repair talks. Mark Malady builds it into the start of assessment. His team runs a motivational interview called Engage before they assess. They do it with both the learner and the caregiver.

what we do with that is we actually will do the motivational interview with both parties and then we'll show the difference and then we can overlay both of the milestones on top of the data set. From the talk. Mark Malady

This surfaces what each person actually wants. The team then finds goals that fit both views. You can see this method in genArete: Milestone based comparison criteria in Skill Assessment.

Brian Middleton calls MI essential to the whole job. He notes it is used far beyond ABA. There is even a book on pairing MI with behavior analysis. His point is that MI helps when a caregiver or staff member shuts down.

motivational interviewing is really essential to what we do. From the talk. Brian Middleton

Brian raises MI while teaching how to translate clinical jargon into plain talk. You can find that in Verbal Behavior & Functional Language: A Practical Guide to Translating from & to Behaviorese.

Common mistakes to avoid#

The biggest trap is talking too much. Many clinicians rush to explain and advise. MI asks you to hold back and let the caregiver think. Silence can do more work than another tip.

Another trap is asking questions that end in yes or no. Those close the door on real reflection. Open-ended questions invite the caregiver to say more. The more they talk, the more they move toward change.

Watch out for arguing with resistance too. Pushing against a caregiver's doubt only hardens it. Reflect the doubt back instead of fighting it. That respect often softens the resistance on its own.

What the research says#

MI is a strong fit for behavior analysts who want stronger relationships. One survey asked 277 BCBAs about alliance skills like reflective listening and affirmations. The authors introduce MI as an evidence-based way to build a therapeutic alliance and call for explicit training in it (Plattner, C., & Anderson, C. (2023). Therapeutic Relationships in Applied Behavior Analysis: Current Status and Future Directions. Behavior Analysis in Practice, 16(4), 1222-1230).

Getting staff to actually use MI can be its own challenge. In a large trial across 26 sites, teams were paid a small amount for each MI session delivered. Adding that incentive had a large effect on how much MI got used (Garner, B. R., Tueller, S. J., Bradshaw, M., Speck, K. J., Satre, D. D., Rash, C., Donohoe, T., Mungo, J., Philbrick, S., Ruwala, R., Roosa, M. R., Zehner, M., & Ford, J. H. (2025). Using Incentivization as a Strategy to Improve Implementation of a Motivational Interviewing Brief Intervention for Substance Use Disorders in HIV Settings: Results of a 26-Site Parallel Groups Cluster-Randomized Type-3 Hybrid Trial. Implementation Research and Practice, 6). Good methods still need support to stick.

FAQ#

What is motivational interviewing? It is a guiding style of talk that helps people change. You ask open questions and listen more than you speak. The person then reaches the decision on their own. Change tends to last when it feels self-chosen.

How do BCBAs use motivational interviewing? They use it to build caregiver buy-in and repair trust. They ask open-ended questions and reflect back what they hear. They affirm effort and summarize before ending a meeting. This turns a tense talk into a shared plan.

Is motivational interviewing evidence-based in ABA? MI has strong support in many fields and growing use in ABA. Behavior analysts describe it as a way to build a therapeutic alliance. There is even a book pairing MI with behavior analysis. Research shows teams may need support to use it often.
