Motivational interviewing, usually called MI, is a collaborative way of talking about change. It helps a person explore what matters to them, understand mixed feelings and consider their own reasons for taking a different direction. The conversation is guided, but the person is not supposed to be argued, shamed or manipulated into agreement.
You do not have to arrive certain that you want to change. Wanting the benefits of a behaviour while also being worried about its consequences is a common reason to seek help. MI provides a framework for discussing that tension honestly, with relevant clinical advice and practical support when needed.
What is motivational interviewing?
The Motivational Interviewing Network of Trainers describes MI as a communication approach that supports autonomy and draws on the person’s own priorities. The practitioner brings professional knowledge, while you bring expertise about your life. It is not a technique for making someone say what a clinician wants to hear. MINT: understanding motivational interviewing.
MI is used in substance-use care and other health-behaviour settings. It may form part of an assessment, a brief intervention or a longer treatment programme. A clinician should explain its role in the particular service, rather than imply that one conversation is a complete treatment for every concern.
Why mixed feelings matter
Someone may want to reduce drinking but worry about losing their main way of relaxing or socialising. Another person may want better health while feeling doubtful that another attempt will succeed. These are not necessarily signs of dishonesty or a lack of character. They are important parts of the problem that a useful conversation needs to understand.
MI does not require dismissing the perceived benefits of a behaviour. It can explore what that behaviour provides, what it costs and what alternatives would need to offer. A plan is more meaningful when it addresses the reasons someone is hesitant rather than simply repeating the risks they already know.
What happens in an MI conversation?
SAMHSA describes four connected processes: building a working relationship, agreeing a focus, exploring the person’s reasons for change and planning when appropriate. The conversation can move between them. Planning is not automatically the first step, especially when the goal itself is still uncertain. SAMHSA’s motivational interviewing guidance.
A practitioner may ask open questions, reflect what they have understood and summarise the different priorities you have expressed. You can correct the summary. The purpose is not to interrogate you or collect a sequence of yes answers, but to make the discussion accurate enough to support a useful decision.
Information still matters. A clinician can explain a health risk, discuss treatment options or recommend urgent care. Respecting autonomy does not mean withholding important facts. It means explaining the advice and recognising your perspective rather than using professional authority as a substitute for a conversation.
An example: wanting change and fearing it
Imagine that evening drinking has started to affect your mornings. You are concerned about concentration at work, but alcohol also marks the end of a stressful day. A simplistic response would be to tell you to stop making excuses. A more useful conversation could examine both the wish for clearer mornings and the need for a workable way to unwind.
You might discover that the immediate goal is a proper assessment of drinking and sleep, rather than a promise to manage everything alone. The next step could involve discussing medical risk and identifying support for the stressful transition after work. The plan should follow from the conversation, not from a script designed to secure compliance.
This example is not a recommendation to change alcohol use without medical advice. When physical dependence is possible, reducing or stopping can require a clinical plan. Motivation does not remove withdrawal risk.
What does the evidence show?
A multisite randomised trial involving 423 people entering community substance-use treatment examined adding MI to the initial assessment. It found better early treatment retention in the MI group, but no significant advantage in substance-use outcomes at the reported follow-ups. Engagement and reduced substance use are different outcomes, and both should be described accurately. Read the original effectiveness study.
SAMHSA includes MI in its guidance on strengthening motivation in substance-use treatment. Its usefulness depends on how it is delivered, the setting and the outcome being sought. A respectful conversation may help someone engage, but it does not by itself establish that all medical, psychological and social needs have been addressed.
Ask what the service expects MI to achieve and how it will assess progress. A claim that the approach is evidence-based should be accompanied by an explanation of the relevant application. It should not become a promise that a reluctant person can always be persuaded or that ongoing difficulties mean insufficient motivation.
MI, MET and CBT: related but different roles
Motivational enhancement therapy, or MET, uses motivational principles within a more structured assessment-and-feedback intervention. MI is the broader communication approach. The terms are related but should not be used as though every MI conversation constitutes a full MET programme.
CBT and relapse-prevention work can help develop skills for managing high-risk situations and responding to setbacks. MI may help clarify whether and why to make a change, while skills-based treatment addresses how to carry it out. People may benefit from both within a coordinated plan.
Medical treatment, practical help and chosen recovery support can be equally important. The alcohol-use treatment guide and opioid-use treatment guide explain why care should be matched to the substance and individual needs.
Safety cannot wait for perfect readiness
Alcohol withdrawal can be dangerous when someone with physical dependence stops suddenly. NIAAA advises medical help to plan a safe change after prolonged heavy drinking. A decision reached in therapy should therefore connect to appropriate assessment rather than an unsupported instruction to quit immediately. NIAAA: planning changes in drinking.
Other urgent needs, including suspected overdose, severe deterioration or inability to remain safe, require prompt local care. A person should not have to complete a motivational programme before receiving essential medical help. Our withdrawal and deprescribing guide explains why medical planning is separate from willpower.
When someone else is worried
Family members may hope that a clinician will convince a loved one to accept treatment. MI is not a guarantee of that outcome. The person’s autonomy remains important, and the concerned relative may need support of their own. A useful service should make clear whose goals are being discussed and who the clinician is working for.
For supporters, CRAFT is a distinct approach worth understanding. Neither method makes one adult responsible for controlling another. Where there is violence, coercion or risk to children, safeguarding and individual safety planning take priority over communication exercises.
Practical barriers and a realistic plan
A person may be ready for change but unable to access transport, afford appointments or find a private place to speak. Pain, unstable housing and caring responsibilities can also affect what is possible. These are practical constraints, not simply beliefs that need to be challenged. The plan should identify help for the barriers rather than count them as a lack of commitment.
When a next step is agreed, make it specific enough to understand: what is being arranged, who is responsible and when progress will be reviewed. Discuss what happens if the plan does not work. Returning for support should remain possible without having to present a flawless account of success.
Frequently asked questions
Is motivational interviewing a form of persuasion?
It is intended to support an informed, personally meaningful decision, not to pressure someone into a predetermined answer. The clinician may give clear advice, especially about health risks, while still recognising your right to ask questions, disagree and understand alternatives.
Do I need to be ready to change before attending?
No. Mixed feelings can be a useful starting point. You can discuss what concerns you and what makes change difficult without pretending to have made a final decision. Immediate medical or safety needs should still be assessed rather than postponed until you feel fully ready.
Is MI only used for addiction?
No. It is used in several health and behaviour-change settings. However, experience with MI does not establish competence to treat every underlying condition. Ask about the professional’s qualifications and how the conversation connects to appropriate care for the concern you bring.
How many appointments does MI involve?
It may be used briefly or integrated into a longer programme. The number depends on the purpose and wider needs. Ask whether you are being offered a standalone intervention, an assessment using MI principles or ongoing treatment that includes other methods.
What if I have tried to change before?
Previous attempts can provide useful information about what helped, what was difficult and which supports were missing. They do not prove that another attempt is pointless. A constructive discussion should look beyond motivation to medical needs, coping skills and practical circumstances.
Can MI be used alongside medication?
Yes, it can support discussion and engagement within a plan that includes prescribed treatment. It should not be used to delay indicated medication or pressure someone to stop it. Questions about medicines belong in an informed conversation with the prescribing clinician.
How do I know the practitioner is properly trained?
Ask about relevant professional qualifications, MI training, supervised practice and feedback on their work. A short course certificate alone does not explain clinical competence. You should also receive clear information about confidentiality, fees, the purpose of sessions and how concerns can be raised.
Beginning the conversation
You can start with a question rather than a commitment: what worries you, what you value and what would make support useful. An initial assessment can consider these priorities alongside health and safety needs before agreeing the appropriate next steps.
