Motivational Interviewing (MI) for Addiction

Medically reviewed by Dr. Eric Chegouri, MD, Medical Director · Last reviewed November 7, 2026

Almost no one walks into addiction treatment feeling one hundred percent sure. Part of you may want things to change, and part of you may miss the relief, the routine or the social life that came with drinking or using. That push and pull is called ambivalence, and it is completely normal. Motivational interviewing, or MI, is an approach built to work with it rather than against it.

Instead of telling you why you should change, an MI-trained clinician helps you hear your own reasons, in your own words. People tend to believe what they hear themselves say. When the case for change comes from you, it is far more likely to last than any argument someone else makes for you.

What is motivational interviewing?

Motivational interviewing was first described by psychologist William R. Miller in 1983, based on his work with problem drinkers, and was developed further with psychologist Stephen Rollnick. At the time, much addiction treatment relied on confrontation: breaking through "denial" and pushing people to admit they had a problem. Miller noticed that this often made people dig in harder.

MI took the opposite approach. It treats you as the expert on your own life, assumes that motivation for change already exists inside you, and focuses on drawing it out. Miller and Rollnick describe MI as a collaborative conversation style for strengthening a person's own motivation and commitment to change.

A structured, shorter format built on MI, called motivational enhancement therapy (MET), was studied in the large NIAAA-funded Project MATCH trial on alcohol treatment. Both MI and MET are now widely used across addiction and health care.

Why does ambivalence matter in recovery?

Ambivalence is not the same as not caring. It means you hold two sets of feelings at once. You may know drinking is hurting your marriage and also feel that it is the only thing that helps you unwind. You may want to stop using opioids and also be terrified of how you will feel without them.

When someone argues hard for one side, the natural human reaction is to defend the other. That is why lectures, ultimatums and scare tactics so often backfire, even when they come from love. MI avoids that trap. The clinician does not take sides in your internal debate; they help you look at both sides honestly, then notice and strengthen the part of you that wants something different.

How does motivational interviewing work?

The spirit of MI

MI is defined as much by its attitude as by its techniques. Miller and Rollnick describe this spirit in four parts: partnership (working with you, not on you), acceptance (respecting your autonomy and worth), compassion (keeping your well-being at the center) and evocation (drawing out your ideas rather than installing someone else's).

Four processes

1. 1Engaging

   Building a trusting, respectful working relationship. Without this, nothing else works.

2. 2Focusing

   Agreeing together on what to talk about, such as drinking, a specific drug, staying in treatment or taking medication.

3. 3Evoking

   Drawing out your own reasons, hopes and ideas for change, and strengthening them.

4. 4Planning

   When you are ready, turning motivation into a concrete plan that you choose and commit to.

Change talk and sustain talk

In MI, the things you say in favor of change are called change talk ("I don't want my kids to see me like this," "I could probably go a week"). Statements in favor of things staying the same are called sustain talk ("It's not that bad," "Everyone I know drinks"). Both are normal. An MI clinician listens closely for change talk, reflects it back and invites you to say more, because research on MI suggests that how much change talk people express is linked to later change.

What does an MI session look like?

An MI session usually feels like a calm, respectful conversation. There is no script you must follow and no one telling you what kind of person you are. The clinician relies on a core set of communication skills often summarized as OARS:

A clinician may also use simple tools such as a readiness ruler: "On a scale from 0 to 10, how important is it to you to stop? Why a 6 and not a 3?" The second question is the clever part. It invites you to explain your own reasons for change rather than defend why you are not further along.

Is motivational interviewing effective?

MI and motivational enhancement therapy have been studied extensively for substance use. NIDA describes motivational enhancement therapy as an effective approach for engaging people in treatment, particularly for alcohol and marijuana use. NIAAA likewise lists motivational enhancement among the behavioral treatments with research support for alcohol use disorder, and SAMHSA has published clinical guidance on using motivational approaches in substance use treatment.

MI tends to be especially useful for getting started: helping people engage, stay in treatment and commit to a plan. It is commonly combined with other therapies that build skills, such as CBT, for the work that follows.

Who does motivational interviewing help?

MI can help almost anyone, at almost any stage. It is especially useful if you:

• Are unsure whether you really have a problem, or whether you need treatment.
• Feel pressured into treatment by family, work or the courts and are not sure what you want for yourself.
• Want to cut back on alcohol or a drug but feel torn about stopping entirely.
• Are weighing a big decision, such as starting medication-assisted treatment or extending your stay.
• Have had a lapse and feel discouraged about trying again.
• Have felt judged or lectured in past treatment experiences.

How is motivational interviewing used at Reggie's?

At Reggie's Recovery Center, motivational interviewing is used in individual and group sessions across residential and outpatient care. It helps strengthen your own commitment to change, which matters at every stage, not just the beginning.

Early in residential treatment, MI can help you settle into the decision to be there, especially on the hard days when leaving feels tempting. Later, it supports decisions about step-down care, sober living or medication. In PHP and IOP, as you face real-world pressures again, MI helps you reconnect with why you started when motivation dips.

Motivation is rarely a straight line. It rises and falls with stress, mood and circumstances. MI treats those dips as expected, not as failure, and gives you a way back to your reasons.

How does MI work with other therapies?

• CBT: MI strengthens the why; CBT builds the how. They are among the most common pairings in addiction care.
• Relapse prevention: MI helps you recommit after a slip, while relapse prevention maps out what to do differently.
• Family therapy: families can learn MI-style communication to reduce arguments and support change.
• 12-Step facilitation: for clients who choose it, MI can help you explore whether mutual-help groups fit your goals, without pressure.

What motivational interviewing is not

MI is not a way to trick or manipulate someone into treatment. It respects your autonomy, including your right to make choices your clinician might not make. It is also not passive listening: MI is purposeful and steers gently toward change.

On its own, MI does not teach coping skills, treat trauma or manage withdrawal. It works best as one part of a larger plan. If you are physically dependent on alcohol, benzodiazepines or opioids, medical care comes first, and our medical detox team is available 24/7.

How do you get started?

You do not need to feel fully ready to call. Many people start the conversation feeling exactly as torn as this page describes. Call (818) 355-1200 to talk confidentially with admissions. A free insurance check usually takes 15 to 30 minutes, and most major PPO plans cover treatment at least in part, depending on your plan. Learn more on our insurance page.
