OARS stands for Open-ended questions, Affirming, Reflective listening, and Summarizing. These are the four core communication skills used in motivational interviewing (MI), a counseling approach developed by psychologists William Miller and Stephen Rollnick to help people work through ambivalence and move toward behavior change. Whether you encountered this acronym in a training, a textbook, or a therapy session, here’s what each component actually means and how they work together.
Where OARS Comes From
Motivational interviewing was designed to help people resolve mixed feelings about change, particularly around health behaviors, substance use, and chronic disease management. Rather than telling someone what to do, MI uses a collaborative conversation style that draws out a person’s own reasons for change. OARS represents the foundational skill set that makes this possible. The framework is outlined in Miller and Rollnick’s Motivational Interviewing: Helping People Change (now in its third edition), which remains the standard reference used by the Motivational Interviewing Network of Trainers.
Open-Ended Questions
Open-ended questions are questions that can’t be answered with a simple “yes” or “no.” They invite the other person to reflect, elaborate, and share more than the bare minimum. Instead of asking “Do you exercise?” (which gets a one-word answer), an open-ended version might be “What does a typical day look like for you in terms of physical activity?”
The purpose is twofold: it increases the flow of information, and it builds trust by signaling genuine curiosity rather than interrogation. Common examples include “What brings you in today?” or “Tell me about how things have been going.” In practice, open-ended questions shift the balance of a conversation so the person doing the talking is the one exploring their own situation, not just responding to a checklist.
Affirmations
Affirming means recognizing a person’s strengths, efforts, and past successes. It’s not the same as praise, and the distinction matters. Praise tends to center the speaker: “I’m proud of you for making that appointment.” An affirmation centers the other person: “You made a real effort to prioritize your health by scheduling that appointment.” Starting with “you” instead of “I” keeps the focus where it belongs and avoids creating a dynamic where one person is in a position to judge or approve.
Affirmations build hope and confidence. When someone is ambivalent about change, pointing out what they’ve already accomplished (even small things) reinforces their belief that change is possible. This is especially important early in a conversation, when a person may feel defensive or unsure about opening up.
Reflective Listening
Reflective listening is the backbone of motivational interviewing. It means carefully listening to what someone says and then reflecting it back, not as a question, but as a statement that shows you understood. At its simplest, this can be repeating or slightly rephrasing what the person said. At a deeper level, it involves making a guess about the meaning or emotion behind their words.
Reflections come in two broad categories. Simple reflections stay close to the surface: repeating or rephrasing what was said without adding much interpretation. Complex reflections go further. A double-sided reflection, for example, captures both sides of someone’s ambivalence: “On one hand, you enjoy how drinking helps you relax, and on the other, you’re worried about what it’s doing to your sleep.” A reflection of feeling names the emotion underneath the words, which is often the deepest and most connecting form.
Other complex reflection techniques include amplification (reflecting what someone said in a slightly exaggerated way to invite them to push back and explore the other side of their ambivalence), reframing (offering a different way to interpret the same situation), and emphasizing personal choice (reflecting the person’s autonomy and ability to make their own decisions). All of these are ways of communicating empathy without giving advice.
Summarizing
Summarizing pulls together what the person has shared and plays it back in an organized way. It serves as a check on understanding, reinforces the key points the person made, and creates natural transitions in the conversation. There are three types of summaries, each used at different moments.
- Collecting summaries gather a few themes from what the person has said so far, like a progress check mid-conversation.
- Linking summaries connect two parts of the discussion that relate to each other, helping the person see patterns they might not have noticed.
- Transitional summaries wrap up one topic and shift focus to a new one, signaling that it’s time to move forward.
A good summary doesn’t just prove you were paying attention. It gives the person a chance to hear their own words reflected back in a structured way, which often clarifies their thinking and strengthens their motivation.
Common Mistakes With OARS
Using OARS effectively is harder than it sounds, because most people default to conversational habits that work against these skills. Miller and Rollnick identified several common traps that undermine the process.
The assessment trap turns a conversation into a rapid-fire question-and-answer session, where the practitioner asks closed question after closed question and the other person gives short, passive responses. The expert trap happens when the practitioner jumps into advice-giving mode before the person has had a chance to explore their own thoughts. The premature focus trap pushes toward a specific topic before the person is ready to go there. The labeling trap applies a diagnostic label (like “alcoholic”) that triggers defensiveness and shuts down the conversation. Even the chat trap, where the conversation stays superficial and friendly without ever going anywhere meaningful, can derail the process.
Each of these traps pulls the conversation away from the person’s own exploration and back toward the practitioner’s agenda, which is exactly what OARS is designed to prevent.
Where OARS Is Used
OARS skills were originally developed for substance use counseling, but they’ve spread far beyond that setting. Healthcare providers use them in primary care to discuss weight management, medication adherence, and chronic disease. Mental health professionals use them across a range of therapeutic contexts. The Agency for Healthcare Research and Quality promotes OARS as a general framework for building rapport with patients in any clinical setting.
The skills are also taught outside of healthcare entirely. Social workers, educators, coaches, and managers use OARS-based techniques when they need to have productive conversations about change without resorting to lecturing or directing. The underlying principle is the same in every setting: people are more likely to change when they talk themselves into it than when someone else tries to talk them into it. OARS creates the conditions for that to happen.
