Motivational Interviewing

MI is built on a simple observation: the more someone else argues for change, the more you argue for staying the same. So your therapist does the opposite. They listen for both sides of the ambivalence, reflect them back without trapping you, and give more airtime to the change talk that is already coming out of your mouth. Open questions, accurate reflections, summarizing, and asking permission before advice are the mechanics. The attitude underneath them is respect for your reasons, including the ones that look, from the outside, like the problem.

You might explore what the habit is doing for you, what it is costing, and what a smaller or different next step could be, without being marched toward abstinence as the only respectable outcome. When discrepancy shows up, I want to be present for my kids, and I keep disappearing into this, the therapist helps you sit with it rather than papering it over. You practise putting your own reasons into words, because reasons you hear yourself say tend to travel better than reasons someone else handed you. The method can be a short piece of work on its own, or a way of talking that sits inside longer therapy when mixed feelings keep stalling the rest of the work.

Motivational Interviewing can be briefer than a year of weekly therapy. Some people use a handful of sessions focused on one decision. Others meet weekly for 50 minutes over video while MI shapes how a longer piece of work unfolds. The first session is usually about the change in question and the two minds you have about it, not a full life history. Your therapist will ask what you like about the way things are, what you don't, and what, if anything, you want to be different, then stay with your answers instead of leaping to a plan. Later sessions may look at a typical week, a recent slip, or a moment you almost chose differently, always circling back to your values rather than to their agenda. You will not be cornered into a commitment you do not mean. If you say you are not ready, that is data, and the conversation should get more honest rather than more persuasive. You can push back, change the target, or decide the change is not yours. Virtual sessions make it possible to talk about the habit in the same life where it actually happens.

Who it's for. Motivational Interviewing tends to fit people who are already in an argument with themselves. You might want to change a habit and also not want to, and you are tired of being told which side should win. It suits you if advice has made you dig in, and if you need a conversation that can stand the true reasons you have for staying as you are. It is a good fit for drinking, other substance use, and health changes where the behaviour is mixed up with identity, relief, or belonging. It also fits when mixed feelings are stalling a different kind of decision, leaving, starting treatment, telling someone, as long as you are willing to look at both sides without being rushed. Honesty helps more than already being committed.

Who it isn't for. If you already know what you want and need a practical plan, solution-focused therapy will likely get you further, faster. MI is also the wrong first step in medical withdrawal, acute danger, or a crisis that needs stabilization rather than a talk about readiness. It is a poor match if you want a therapist to take over the decision, because the method will keep handing it back to you.

MI is often compared with solution-focused therapy, and the difference is where each one starts. Solution-focused work assumes you can already picture a preferred future and helps you notice steps toward it. MI assumes you may not be sure you want that future yet, and spends the hour with the mixture of wanting and not wanting. If you already know the destination, solution-focused will feel more efficient. If you are still split, MI will feel more honest. It also overlaps with acceptance and commitment therapy, which asks what you value and whether you can carry uncomfortable feelings while you move toward it. ACT is more interested in willingness and action in the presence of difficult thoughts. MI is more interested in resolving, or at least clarifying, the ambivalence that keeps action from starting. The useful distinction is whether you need help deciding, or help doing the thing you have already decided.

Motivational Interviewing has a growing evidence base, particularly for substance use and health behaviour change, with an important caveat: effects are often small, stronger in the short term, and less clear when MI is compared with other active treatments. Cochrane reviewers have said they have only moderate to very low confidence in much of that evidence, which is a more honest summary than a slogan about MI always beating advice. There are also medical-setting trials that find a modest advantage for some alcohol, tobacco, and activity outcomes, and a large review of reviews that lands in a similar place. That is still useful. It is not a reason to treat MI as a magic conversation that produces change on its own, and it does not replace medical care when withdrawal or danger is in the room.

Schwenker, R., et al. (2023), Cochrane Database of Systematic Reviews. A Cochrane review found MI may reduce substance use compared with no intervention in the short term, and may make little to no difference compared with usual care or another active treatment. The authors reported moderate to very low confidence in much of the evidence.

Lundahl, B., et al. (2013), Patient Education and Counseling. A meta-analysis of 48 randomized trials in medical settings found a modest overall advantage for MI compared with control conditions, including for some alcohol, tobacco, and other health-behaviour outcomes, with weaker findings in other areas such as eating-disorder behaviours.

Frost, H., et al. (2018), PLoS One. A systematic review of reviews found moderate-quality evidence of small, mainly short-term benefits of MI for binge drinking, alcohol use, substance use in people with dependence, and physical activity, while most other meta-analytic findings were graded low or very low quality.
