Lesson 5 - Motivational Interviewing
1. Introduction
People do not always change simply because they know what would be good for them.
Someone may know that alcohol is worsening their depression and continue drinking.
Someone may understand that avoiding social situations maintains their anxiety and still feel unable to leave the house.
A patient may know that taking medication consistently is important but remain deeply uncertain about whether they want to take it.
Someone may want to return to work while simultaneously feeling terrified about trying.
This is not necessarily a lack of motivation.
Often it is ambivalence.
Ambivalence means experiencing competing reasons both for and against change.
For example:
“I want to stop drinking because it is ruining my relationship.”
And:
“I don’t know how I would cope without alcohol.”
Both statements can be true at the same time.
Motivational interviewing, often shortened to MI, is a collaborative conversational approach designed to help people explore this kind of ambivalence and strengthen their own motivation for change.
The important phrase is:
Their own motivation.
Motivational interviewing is not primarily about persuading someone to do what the practitioner wants.
It is not arguing.
It is not lecturing.
It is not telling someone why they are wrong.
It is not manipulating them into agreeing with a treatment plan.
Instead, MI aims to create a conversation in which the person is able to hear and develop their own reasons for change.
This fits closely with recovery-oriented and personalised mental health care.
NHS England’s personalised care approach emphasises that people should be active participants in decisions about their care, with conversations based on what matters to them, their individual strengths, needs and goals.
Motivational principles are particularly useful for case workers because they regularly encounter situations where people feel uncertain about:
Medication.
Therapy.
Substance use.
Exercise.
Returning to work.
Attending appointments.
Changing routines.
Reducing avoidance.
Engaging with treatment.
Building social contact.
However, there is an important scope-of-practice point.
Using motivational interviewing principles in everyday conversations is different from delivering formal MI or motivational enhancement therapy as a structured specialist intervention.
NICE guidance on drug misuse explicitly states that formal psychosocial interventions require appropriate competence, training and supervision.
For this course, the goal is therefore to help case workers communicate in a more motivationally informed way while remaining within their competence and the agreed care plan.
This lesson builds directly on the previous lessons.
Building Rapport established a collaborative relationship.
Active Listening taught us to understand before responding.
Empathy and Validation taught us to recognise the person’s perspective.
Asking Effective Questions taught us how to explore without interrogating.
Motivational interviewing brings these skills together and asks:
How can we help someone think about change without pushing them into it?
2. Learning Outcomes
By the end of this lesson learners should be able to:
Explain the basic purpose and spirit of motivational interviewing.
Recognise ambivalence, change talk and sustain talk during clinical conversations.
Use the core OARS communication skills: open questions, affirmations, reflections and summaries.
Recognise and reduce the “righting reflex” to argue, persuade or prematurely solve problems.
Use simple motivational strategies such as importance and confidence questions and eliciting the person’s own reasons for change.
Recognise situations where motivational conversation is inappropriate or must give way to clinical assessment, safeguarding or urgent escalation.
3. The Lecture
What Is Motivational Interviewing?
Motivational interviewing is a collaborative style of communication that helps strengthen a person’s own motivation and commitment to change.
The emphasis is not:
“How do I make this person change?”
The more useful question is:
“How do I help this person explore whether change matters to them and what might make it possible?”
This distinction is fundamental.
The practitioner is not dragging the patient towards a goal.
They are helping the patient examine the path.
Why Telling People What to Do Often Fails
Healthcare professionals naturally want to help.
When we see someone doing something harmful, our instinct is often:
Correct it.
Explain the risks.
Tell them what to do.
For example:
Patient:
“I’m still drinking every night.”
Practitioner:
“You need to stop. Alcohol is making your depression worse.”
The statement may be clinically accurate.
The patient may respond:
“I know, but it’s the only thing that helps.”
The practitioner says:
“But it’s making you worse.”
The patient says:
“You don’t understand.”
The practitioner provides more evidence.
The patient provides more reasons not to change.
Something important has happened.
The practitioner is now arguing for change.
The patient is arguing against it.
This is the opposite of what we want.
The Righting Reflex
Motivational interviewing describes the natural urge to correct another person as the righting reflex.
The practitioner sees a problem and wants to make it right.
Examples include:
“You need to take your medication.”
“You should exercise more.”
“You need to stop avoiding things.”
“You must stop drinking.”
“You need to attend therapy.”
The advice may be reasonable.
The timing may not be.
When someone is ambivalent, strong persuasion often produces a counterargument.
Practitioner:
“You should go back to university.”
Patient:
“I’m not ready.”
Practitioner:
“But staying at home is making things worse.”
Patient:
“If I go back I’ll fail again.”
The more the practitioner argues for change, the more the patient rehearses reasons not to change.
Motivational Interviewing Changes Who Makes the Argument
Instead of the practitioner giving all the reasons for change, MI helps the patient identify them.
For example:
“What worries you most about continuing to drink the way you are now?”
The patient says:
“My girlfriend says she’s going to leave.”
Then:
“What else concerns you?”
“I’ve started missing work.”
Now the patient is saying the reasons for change.
This is much more powerful than the practitioner listing them.
Ambivalence Is Normal
Ambivalence is not resistance.
It is often a normal part of behaviour change.
Imagine thinking about changing jobs.
You may think:
“I hate this job.”
And:
“I’m frightened of losing financial security.”
Both can coexist.
Similarly:
“I want to stop smoking cannabis.”
And:
“It is the only thing that helps me relax.”
“I want to go back to college.”
And:
“I’m terrified of having another panic attack.”
“I want therapy.”
And:
“I don’t want to talk about painful things.”
Motivational interviewing works with this ambivalence rather than treating it as defiance.
Do Not Rush to Resolve Ambivalence for the Patient
Practitioner:
“Part of you wants to stop drinking and part of you finds alcohol really useful.”
Patient:
“Yes.”
Poor response:
“So obviously you should stop.”
Better response:
“Tell me a little more about both sides.”
The aim initially is understanding.
Ambivalence often becomes clearer when the person hears themselves describe both sides.
The Spirit of Motivational Interviewing
MI is more than a set of techniques.
It has an underlying spirit.
Four ideas are particularly important:
Partnership.
Acceptance.
Compassion.
Evocation.
Partnership
The practitioner works with the person rather than acting as the expert who has all the answers.
This does not mean pretending the practitioner has no expertise.
The clinician may know:
The evidence.
The risks.
The treatment options.
The patient knows:
Their life.
Their values.
Their fears.
Their priorities.
Their previous experiences.
Both forms of expertise matter.
NHS England describes personalised care as a relationship in which people are active participants and experts in the context of their own lives.
Acceptance
Acceptance does not mean agreeing with every decision.
It means respecting the person’s worth and autonomy.
The person ultimately makes many of their own choices.
The practitioner can:
Provide information.
Explore consequences.
Discuss risk.
Recommend treatment.
But coercive persuasion is different from collaborative clinical care.
Compassion
The practitioner should work in the interests of the patient rather than trying to “win” the conversation.
The purpose is not:
Getting compliance.
Proving the practitioner is correct.
Completing a target.
The purpose is helping the person make informed decisions that support their health and recovery.
Evocation
Evocation means drawing out what is already within the person.
Instead of saying:
“Here are five reasons why you should change.”
ask:
“What would be better in your life if this changed?”
The practitioner evokes:
Values.
Goals.
Concerns.
Hopes.
Reasons for change.
Confidence.
The Four Processes of Motivational Interviewing
Formal MI is often described through four overlapping processes:
Engaging.
Focusing.
Evoking.
Planning.
These are not rigid stages.
You may move backwards and forwards between them.
Engaging
Engaging is about establishing a collaborative relationship.
This uses the skills already covered in this course:
Rapport.
Active listening.
Empathy.
Validation.
Curiosity.
If the person feels judged, motivational work is unlikely to be productive.
Focusing
Focusing means agreeing what change you are actually talking about.
For example:
The patient has problems with:
Alcohol.
Sleep.
Medication.
College.
Anxiety.
Family conflict.
You cannot work effectively on everything at once.
You might ask:
“Of all the things we have discussed, which feels most important to work on first?”
This makes the focus collaborative.
Evoking
Evoking is at the heart of MI.
The practitioner helps the person identify their own:
Reasons for change.
Concerns about the current situation.
Desire for improvement.
Confidence.
Values.
This is where change talk becomes important.
Planning
Planning happens when the person is moving towards change.
The practitioner helps turn motivation into realistic action.
For example:
“What would be a manageable first step?”
Planning should not be rushed.
If someone is still deeply ambivalent, immediately creating an action plan may be premature.
OARS
A core set of MI communication skills can be remembered using OARS.
Open questions.
Affirmations.
Reflections.
Summaries.
These will already be familiar from earlier lessons.
MI uses them deliberately to explore and strengthen motivation.
Open Questions
Open questions invite exploration.
Examples include:
“What concerns you about the way things are going?”
“What would you like to be different?”
“What do you like about drinking?”
“What do you not like about it?”
“What would returning to work mean to you?”
“What makes you uncertain about medication?”
These questions allow ambivalence to emerge.
Affirmations
An affirmation recognises something positive, such as:
Effort.
Strength.
Persistence.
Values.
Insight.
Achievement.
For example:
“You’ve kept attending appointments even though talking about this is difficult.”
“You were honest about starting to drink again even though you were worried about how the team might respond.”
“You’ve clearly thought carefully about the advantages and disadvantages.”
Affirmations should be genuine.
They are not empty praise.
Affirmation Is Not Saying “Well Done” Constantly
Generic praise can become patronising.
Instead of:
“Well done!”
try:
“You managed to go into the shop despite feeling anxious. That took a lot of persistence.”
Specific affirmation identifies the strength.
Reflections
Reflections communicate your understanding.
Patient:
“I hate taking medication, but I also don’t want to end up back in hospital.”
Reflection:
“You feel trapped between not wanting medication and not wanting another relapse.”
This captures ambivalence without solving it.
Complex Reflections
A simple reflection repeats or paraphrases.
A more complex reflection captures underlying meaning.
Patient:
“My family keeps going on about my drinking.”
Simple:
“Your family talks about your drinking a lot.”
Complex:
“Part of what frustrates you is feeling as though everyone else is deciding that alcohol is the problem before they have listened to what it does for you.”
Complex reflections should remain tentative.
If wrong, allow correction.
Summaries
Summaries collect key themes.
For example:
“So on one hand cannabis helps you relax and makes social situations easier. On the other hand you’ve noticed that your paranoia is becoming worse, your concentration has dropped and you are worried about college. You’re not sure whether you want to stop, but you are increasingly worried about what happens if nothing changes.”
A summary allows the patient to hear their own ambivalence clearly.
Change Talk
Change talk refers to language from the patient that moves towards change.
Examples include:
“I want things to be different.”
“I need to cut down.”
“I probably could manage without cannabis a few nights a week.”
“I’m worried about what this is doing to my relationship.”
“I’ve managed to stop before.”
“I’m going to speak to the prescriber.”
The practitioner listens carefully for these statements.
DARN
One way of recognising preparatory change talk is DARN.
Desire.
Ability.
Reasons.
Need.
Desire
“I want to…”
“I wish…”
“I’d like…”
For example:
“I want to feel like myself again.”
Ability
“I could…”
“I might be able to…”
“I’ve done it before.”
For example:
“I could probably start by attending one lecture.”
Reasons
Change would lead to something valuable.
For example:
“If I stopped drinking during the week, I’d probably do better at work.”
Need
Statements expressing necessity.
“I need to…”
“I can’t keep…”
“Something has to change.”
For example:
“I can’t keep living like this.”
CAT
As motivation develops, change talk may move towards commitment.
This can be remembered as CAT.
Commitment.
Activation.
Taking steps.
Commitment
“I will…”
“I’m going to…”
Activation
“I’m ready to…”
“I’m willing to…”
Taking Steps
“I called the service yesterday.”
“I poured the alcohol away.”
“I went for a walk.”
These statements suggest movement from considering change towards acting.
Sustain Talk
Sustain talk is language in favour of maintaining the current behaviour.
Examples include:
“Drinking is the only thing that helps me sleep.”
“I don’t think medication is the problem.”
“I’m not ready to go back to work.”
“If I stop cannabis I’ll have nothing.”
Sustain talk is not bad behaviour.
It reflects the other side of ambivalence.
Do not attack it.
Explore it.
Do Not Fight Sustain Talk
Patient:
“I’m not ready to stop drinking.”
Poor response:
“But you have to.”
Better:
“You’re not at the point where stopping completely feels realistic.”
Then perhaps:
“What, if anything, worries you about continuing as you are?”
The practitioner stays alongside the patient rather than entering an argument.
Discord
Discord refers to tension within the working relationship.
Examples include:
“You don’t understand.”
“You’re judging me.”
“You’re telling me what to do.”
“This is pointless.”
Discord is different from sustain talk.
Sustain talk is about the behaviour.
Discord is about the relationship.
If discord develops, do not push harder.
Return to engagement.
For example:
“I think I’ve been pushing my own view too strongly. Let me understand what this is like from your side.”
That can repair the conversation.
Resistance Is Often Relational
Calling someone “resistant” can imply that the problem belongs entirely to them.
MI encourages us to ask:
“What is happening in this conversation that is producing pushback?”
Sometimes increased argument from the patient follows increased pressure from the practitioner.
Changing our approach can change the interaction.
Eliciting Change Talk
The practitioner can ask questions likely to invite change talk.
Examples include:
“What worries you about continuing like this?”
“What would be better if things changed?”
“What would you like your life to look like in six months?”
“What makes this important to you?”
“What gives you confidence that you could make a change?”
“What has worked previously?”
Ask About the Downsides of the Current Situation
Patient:
“I don’t really want to reduce cannabis.”
You might ask:
“What, if anything, do you dislike about it?”
The phrase:
“If anything”
is useful.
It reduces pressure.
Ask About the Advantages of Change
“What might be better if you cut down?”
“What would returning to college give you?”
“What would improve if your sleep became more regular?”
The person generates their own reasons.
Looking Back
Sometimes previous functioning reveals motivation.
“What was life like before your drinking increased?”
“What do you miss about how things used to be?”
This can highlight discrepancy between the present and valued life.
Looking Forward
You can also ask:
“If nothing changes, what do you think life may look like in a year?”
and:
“If things improve, what would you hope life looks like?”
Use this carefully.
The aim is exploration, not frightening the patient.
Developing Discrepancy
MI can help people notice differences between:
Current behaviour.
And personal values.
For example:
The person values being a reliable parent.
Alcohol repeatedly causes missed contact with their children.
The practitioner does not need to accuse:
“You say your children matter but you keep drinking.”
That creates shame.
Instead:
“You’ve said being there for your children matters enormously to you. How does the drinking fit with the kind of parent you want to be?”
The person is invited to explore the discrepancy themselves.
Do Not Weaponise Values
Values should not be used to shame.
Avoid:
“If you really cared about your family, you’d stop.”
That is not motivational interviewing.
Importance Rulers
A simple motivational strategy is an importance scale.
For example:
“On a scale from 0 to 10, where 0 means changing this is not important at all and 10 means it is extremely important, where would you say you are?”
Patient:
“Six.”
A common mistake is to ask:
“Why not ten?”
This invites reasons against change.
Instead ask:
“Why a six and not a three?”
Now the person describes what makes change important.
Confidence Rulers
You can similarly ask:
“On a scale from 0 to 10, how confident are you that you could make this change if you decided to?”
Patient:
“Four.”
Then:
“What makes it a four rather than zero?”
This identifies strengths.
Then:
“What might move it from four to five?”
This helps identify practical support.
Importance and Confidence Are Different
A patient may say:
Importance: 9.
Confidence: 2.
They desperately want change but do not believe they can achieve it.
That suggests the task may be to build:
Self-efficacy.
Support.
A smaller goal.
Problem-solving.
Another patient might say:
Importance: 2.
Confidence: 9.
They believe they could change.
They simply do not currently see a reason to.
The conversation should be different.
Self-Efficacy
Self-efficacy means belief in one’s ability to carry out a behaviour.
MI supports self-efficacy by exploring:
Past successes.
Existing strengths.
Resources.
Manageable steps.
For example:
“You stopped for three months last year. What helped you manage it then?”
This turns previous success into useful information.
Ask Before Giving Advice
One of the most useful MI principles is asking permission before offering information or advice.
For example:
“Would it be okay if I shared some information about how cannabis can affect paranoia?”
This signals respect.
If the patient says yes, provide information briefly.
Then return to their perspective.
“What do you make of that?”
Elicit – Provide – Elicit
A useful information-sharing structure is:
Elicit.
Provide.
Elicit.
First:
Ask what the person already knows.
“What have you heard about the relationship between alcohol and sleep?”
Then:
Provide relevant information.
“Alcohol can make people fall asleep more quickly, but it often disrupts sleep later in the night.”
Then:
Elicit the person's response.
“How does that fit with what you’ve noticed?”
This is usually more collaborative than delivering a lecture.
Avoid the Information Dump
Practitioner:
“Alcohol affects REM sleep, mood, liver function, medication metabolism, blood pressure…”
The patient stops listening.
Give small amounts of information.
Focus on what is relevant to the person.
Ask Permission Without Becoming Artificial
You do not need to ask permission before every sentence.
Use judgement.
The principle is:
Do not assume the patient wants advice simply because you have it.
Supporting Autonomy
An important MI principle is recognising the person's autonomy.
For example:
“Ultimately, whether you make this change is your decision.”
This can sound counterintuitive.
Practitioners sometimes worry it will reduce motivation.
In reality, acknowledging autonomy can reduce the need for the patient to defend it.
Autonomy Does Not Mean Clinical Indifference
Do not say:
“It’s your choice, do what you want.”
That can sound dismissive.
Better:
“The decision is yours. My role is to make sure you have good information, understand the risks and have support if you decide you want to change.”
When Safety Limits Choice
Motivational interviewing does not override:
Safeguarding responsibilities.
Mental capacity law.
Mental health legislation where applicable.
Immediate clinical risk.
A person may have autonomy around many choices while services still have responsibilities where significant risk is present.
For example:
A person says:
“I don’t want anyone to know I’m planning to kill myself tonight.”
The practitioner should not respond:
“MI respects autonomy, so I won’t tell anyone.”
Urgent safety responsibilities take priority.
Planning for Change
When the person starts moving towards change, help develop a realistic plan.
Ask:
“What would you like to do?”
“What is the first step?”
“When might you do that?”
“What could get in the way?”
“What would help?”
“Who could support you?”
Let the Person Generate the Plan Where Possible
Instead of:
“You need to exercise three times a week.”
ask:
“What amount of activity would feel realistic to start with?”
The person may say:
“I could walk for ten minutes after lunch.”
A self-generated plan may feel more achievable.
Make Goals Small Enough to Start
Motivation often collapses when goals are too large.
Goal:
“Get my life back.”
First step:
“Get dressed before midday three days this week.”
Goal:
“Return to university.”
First step:
“Email student support.”
Goal:
“Stop drinking.”
Possible first step within an appropriate care plan:
“Speak with the substance-use clinician about safe options.”
Small steps are not trivial if they move in the direction of a meaningful goal.
Strengthen Commitment Carefully
Once a plan emerges, summarise it.
“So you’ve decided that tomorrow you will call your GP and ask for an appointment about the medication side effects.”
Then ask:
“How does that plan feel?”
Do not make a tentative thought sound like a commitment.
Patient:
“I suppose I could maybe call.”
Practitioner:
“Great, so you definitely will.”
That is too fast.
When Someone Is Not Ready
Sometimes the outcome of a motivational conversation is:
“I’m not ready to change.”
That does not mean the conversation failed.
The practitioner may have improved:
Understanding.
Trust.
Awareness.
Future willingness to engage.
You might say:
“You’re not ready to change this now. If that changes, we can talk about it again.”
Keep the relationship open.
Harm Reduction
Change does not always mean complete cessation.
For some behaviours, depending on clinical context and specialist advice, the immediate goal may involve reducing harm.
NICE guidance on drug misuse recognises different treatment goals, including abstinence and harm reduction, and recommends involving the person in deciding their treatment goals.
Case workers should work within the agreed clinical plan rather than independently devising substance-use treatment.
Motivational Interviewing and Substance Use
MI has a particularly established history in alcohol and substance-use treatment.
NICE recommends that people who misuse alcohol receive a motivational intervention as part of initial assessment, including helping them recognise problems related to drinking, resolving ambivalence and encouraging change without adopting an argumentative or confrontational position.
For drug misuse, NICE recommends brief motivational interventions that explore ambivalence about drug use and possible treatment while providing non-judgemental feedback in appropriate settings.
This is a good illustration of the core MI principle:
Explore rather than confront.
What Does the Evidence Show?
The evidence for MI varies according to the population, problem and comparison intervention.
A 2023 Cochrane review of MI for substance-use reduction included 93 studies involving more than 22,000 participants. The findings suggest that MI can have benefits in some contexts, but the size and certainty of effects vary according to outcome, follow-up period and comparator.
A systematic review and meta-analysis in mental health settings found that MI used before treatment improved subsequent treatment attendance, with particularly notable benefit among people who were initially less motivated to seek mental healthcare.
The important teaching point is not that MI is a universal solution.
It is that collaborative motivational conversations can be useful when ambivalence is a major barrier to engagement or behaviour change.
Motivational Interviewing and Medication
Consider:
Patient:
“I hate taking antipsychotics.”
Practitioner:
“But they stop you becoming unwell.”
This immediately creates two sides.
Instead:
“What do you dislike most about taking them?”
Patient:
“They make me gain weight and they remind me that I’m ill.”
Then:
“What, if anything, do you think they help with?”
Patient:
“I haven’t heard voices as much.”
Now both sides of the ambivalence are visible.
The case worker should not make medication decisions.
But they can help the person articulate concerns for discussion with the prescriber.
Motivational Interviewing and Anxiety
A patient says:
“I want to go out more, but every time I try I panic.”
Instead of:
“You need to push through the anxiety.”
try:
“What would being able to go out more give you?”
Patient:
“I could see my friends.”
Then:
“What makes that important?”
“I’m sick of being alone.”
Now the motivation for exposure or recovery work comes from the patient's values.
Motivational Interviewing and Depression
Depression can reduce energy, hope and confidence.
Avoid framing this simply as low motivation.
Patient:
“I know walking might help, but I can’t make myself do it.”
Ask:
“What makes walking worth considering at all?”
Patient:
“I used to take the dog out every morning.”
“What did you get from that?”
“It gave me a reason to get up.”
This reconnects behaviour with meaning.
Motivational Interviewing and Appointment Attendance
Patient:
“I don’t want to come back.”
Poor:
“You need to engage with the service.”
Better:
“What makes you want to stop coming?”
Patient:
“Every appointment makes me feel like a patient. I’m trying to get back to normal.”
That information matters.
Perhaps the care plan can be adjusted.
Perhaps the patient misunderstood the purpose of appointments.
Perhaps another form of support is more acceptable.
Motivational Interviewing and Self-Harm
Be cautious.
MI principles may help explore ambivalence about changing a coping behaviour.
For example:
“What does self-harm do for you in the moment?”
“What do you dislike about what happens afterwards?”
However, where current self-harm involves significant immediate risk, risk assessment and appropriate clinical management take priority.
Do not remain in a motivational conversation while urgent safety needs are unresolved.
Motivational Interviewing and Eating Disorders
Ambivalence can be very strong in eating disorders.
Some aspects of the illness may feel:
Safe.
Controlled.
Identity-defining.
Valuable.
Simply telling someone:
“You need to eat more.”
may lead to conflict.
Motivational principles can help understand ambivalence.
However, eating disorders can carry serious medical risk and require specialist assessment and treatment.
Case workers should not attempt to provide specialist eating-disorder MI without appropriate training and supervision.
Motivational Interviewing and Psychosis
Motivational approaches may sometimes help with treatment engagement, medication discussions or behaviour change in people experiencing psychosis.
However, do not use MI to debate delusional beliefs.
Focus on areas where the person can identify goals and choices.
For example:
“What would you most like help with?”
The person may say:
“I want to sleep.”
Now there is a shared goal even if there is disagreement about other aspects of the presentation.
Significant acute psychosis still requires appropriate clinical assessment.
The Difference Between MI and Persuasion
Persuasion says:
“Here is why you should change.”
MI says:
“Tell me what makes change worth considering.”
Persuasion says:
“The benefits outweigh the risks.”
MI says:
“How do you see the advantages and disadvantages?”
Persuasion says:
“You need to.”
MI says:
“What do you want?”
Clinical information still matters.
The difference is how it is introduced.
The Difference Between MI and Passive Listening
MI is not simply:
“Whatever you decide is fine.”
It is directional.
There is usually a particular behaviour or goal being explored.
The practitioner listens specifically for:
Motivation.
Values.
Discrepancy.
Change talk.
Barriers.
Confidence.
The practitioner is collaborative but purposeful.
The Difference Between MI and Manipulation
MI should never involve secretly steering someone towards a decision for the practitioner’s benefit.
It relies on:
Transparency.
Respect for autonomy.
Accurate information.
The patient's own values.
A person should not leave the conversation feeling tricked into agreement.
The Difference Between MI and Formal Therapy
Case workers can use MI-consistent communication.
For example:
Open questions.
Reflections.
Exploring ambivalence.
Avoiding confrontation.
Eliciting patient goals.
However, structured MI or motivational enhancement interventions require appropriate training and competence.
NICE guidance on drug-use psychosocial interventions specifies that formal interventions should be delivered by competent staff who receive appropriate supervision.
That is consistent with the earlier lesson on working within competence.
A Practical Framework: MOTIVATE
A useful framework for case workers is MOTIVATE.
M – Meet the Person Where They Are
Do not begin by demanding commitment to change.
Understand their current perspective.
O – Open Up Ambivalence
Explore both sides.
“What do you like about it?”
“What worries you about it?”
T – Tune In to Change Talk
Notice desire, ability, reasons and need.
I – Invite Their Own Reasons
Ask what would make change worthwhile.
V – Validate Autonomy
Recognise that decisions ultimately belong to the person within the relevant clinical and legal framework.
A – Ask Before Advising
Use collaborative information sharing.
T – Turn Motivation Into a Small Step
When readiness appears, ask what realistic action could come next.
E – Escalate When Safety Requires It
Motivational interviewing never replaces urgent clinical care.
Worked Clinical Scenario: Alcohol
Oliver has depression and drinks heavily most evenings.
Case worker:
“How do you feel about the amount you’re drinking at the moment?”
Oliver:
“I know it’s too much, but it’s the only thing that shuts my brain off.”
Poor response:
“You need to stop. Alcohol is making the depression worse.”
MI-consistent response:
“So alcohol gives you relief at night, and at the same time there’s a part of you that thinks the amount has become a problem.”
Oliver:
“Yes. I keep missing work.”
Case worker:
“What worries you most about that?”
Oliver:
“I could lose my job.”
The patient is now making the argument for change.
Worked Clinical Scenario: Medication
Hannah has stopped taking her antidepressant.
Case worker:
“What led you to stop it?”
Hannah:
“I hate depending on medication.”
Case worker:
“Feeling dependent on something is difficult for you.”
Hannah:
“Yes. But I’m also scared the depression will come back.”
Case worker:
“So there are two important concerns: you want to feel independent, and you also want to avoid becoming as unwell as you were before.”
Hannah:
“Exactly.”
The case worker can now help Hannah formulate questions and concerns for the prescriber.
They should not independently tell her whether to restart or stop medication.
Worked Clinical Scenario: Social Anxiety
Jamie wants to return to college but repeatedly avoids attending.
Case worker:
“On a scale from zero to ten, how important is getting back to college?”
Jamie:
“Eight.”
Case worker:
“Why eight rather than four?”
Jamie:
“I want qualifications. I don’t want anxiety deciding my whole life.”
This is change talk.
Then:
“How confident are you that you could take one step towards college this week?”
Jamie:
“Three.”
The issue is not importance.
It is confidence.
Case worker:
“What might move three to four?”
Jamie:
“If I didn’t have to go into a full classroom.”
Now the team can consider a smaller step within the care plan.
Worked Clinical Scenario: Cannabis
Aisha says:
“I’m not stopping cannabis.”
Poor response:
“You need to because it’s worsening your paranoia.”
MI-consistent response:
“You’re not ready to stop.”
Aisha:
“No.”
Case worker:
“What do you like about using it?”
Aisha:
“It makes me relaxed.”
“And what do you like less?”
“The paranoia. Sometimes I can’t leave the house.”
The practitioner is helping ambivalence become visible.
If acute psychosis or serious risk is present, appropriate clinical assessment remains necessary.
Worked Clinical Scenario: Exercise
David has depression.
Case worker:
“You need to exercise.”
David:
“I know.”
Case worker:
“Why aren’t you doing it?”
David:
“I don’t know.”
Alternative:
“You’ve said part of you thinks activity might help. What was different when you were more active?”
David:
“I used to walk with my brother.”
“What did you enjoy about that?”
“We actually talked.”
Now the meaningful target may be:
Connection.
Not merely exercise.
Worked Clinical Scenario: Treatment Engagement
Leah says:
“I don’t want therapy.”
Case worker:
“What concerns you about it?”
Leah:
“I don’t want someone digging through my childhood.”
The practitioner says:
“So you’re worried therapy means being pushed into talking about things you’re not ready to discuss.”
“Yes.”
The team can now explain what the actual therapy involves.
The issue was not lack of motivation.
It was fear.
Worked Clinical Scenario: Safety Overrides MI
Marcus says:
“I know everyone wants me to stop drinking, but I don’t care anymore. I’m going home tonight and taking all my tablets.”
The appropriate response is not:
“What are the pros and cons of taking the tablets?”
This is no longer a routine motivational conversation.
There is a significant safety concern.
The practitioner should respond empathically, clarify immediate safety within their competence and initiate urgent clinical escalation.
4. Clinical Perspective
Clinical Pearls
Ambivalence Is Normal
Do not mistake uncertainty for refusal.
Do Not Argue for Change
If you make all the arguments for change, the patient may end up making all the arguments against it.
Listen for Change Talk
When the patient gives a reason for change, explore it.
Do Not Attack Sustain Talk
It tells you why the current behaviour remains valuable to the person.
Ask Before Giving Advice
Advice is often better received when invited.
Values Are More Powerful Than Instructions
“What matters to you?” is often more useful than “What should you do?”
Confidence and Importance Are Different
Someone may desperately want change but believe they cannot achieve it.
Small Steps Matter
Motivation does not need to lead immediately to a large commitment.
MI Is Collaborative but Not Directionless
You are helping the person explore a particular change.
Safety Overrides Motivational Exploration
Urgent risk requires appropriate clinical action.
Practical Tips for Everyday Practice
When someone appears uncertain about change:
Ask what they like about the current situation.
Ask what they dislike.
Reflect both sides.
Avoid arguing.
Ask what matters to them.
Listen for their own reasons for change.
Ask about previous successes.
Explore confidence.
Offer information briefly and collaboratively.
Ask what they make of the information.
Let the person generate the next step where possible.
Keep goals realistic.
Respect autonomy.
Escalate significant risk.
Useful phrases include:
“What do you like about it?”
“What concerns you about it?”
“What would be better if things changed?”
“What matters most to you?”
“What gives you confidence?”
“What has worked before?”
“Why is it a six rather than a three?”
“Would it be okay if I shared some information?”
“What do you make of that?”
“What feels like a realistic next step?”
Common Pitfalls and Misconceptions
“MI Means Convincing Someone to Change”
No.
It helps people explore and strengthen their own reasons.
“If Someone Is Not Changing, They Lack Motivation”
They may be ambivalent, frightened, overwhelmed or lack confidence.
“I Need to Correct Every Inaccurate Belief About the Behaviour”
Not immediately.
Understanding the person's perspective may need to come first.
“Change Talk Means the Person Has Committed”
Not necessarily.
“I would like to stop” is different from “I will stop tomorrow.”
“Sustain Talk Means the Conversation Is Failing”
No.
It reveals why the behaviour remains attractive or useful.
“MI Means Never Giving Advice”
No.
Advice and information can be important.
MI encourages collaborative information sharing rather than lecturing.
“Respecting Autonomy Means Accepting Unsafe Decisions Without Action”
No.
Professional, safeguarding and legal responsibilities still apply.
“MI Is Just Asking Open Questions”
No.
It also involves reflection, affirmation, summaries, attention to change language and a particular collaborative spirit.
“Anyone Can Deliver Formal MI After Reading About It”
No.
Competent formal delivery requires training, practice and supervision.
“The Goal Is Always Complete Behaviour Change”
Not necessarily.
Sometimes the immediate outcome is increased understanding, engagement or one small step.
Advice for Newly Qualified Practitioners
The biggest challenge is often resisting the urge to fix.
When a patient says:
“I know this is bad for me.”
you do not need to immediately explain why it is bad.
They already know.
Try:
“What makes you say that?”
This invites them to continue the argument for change.
When you hear yourself saying:
“You need to…”
pause.
Ask whether a question might work better.
Instead of:
“You need to get out more.”
try:
“What do you miss about life before you became so isolated?”
Instead of:
“You need to take your medication.”
try:
“What are the things that make you want to take it, and what are the things that make you want to stop?”
You do not need to perform perfect formal MI.
Start with the attitude:
Curious rather than corrective.
Collaborative rather than controlling.
Evoking rather than lecturing.
And bring difficult motivational conversations to supervision.
Situations Requiring Escalation
Motivational interviewing should not delay necessary clinical intervention.
Seek senior clinical advice or follow urgent procedures where there is:
Suicidal intent or planning.
Significant or escalating self-harm.
Serious risk to another person.
New or worsening psychotic symptoms.
Possible mania.
Acute confusion.
Severe deterioration in mental state.
Serious medication adverse effects.
Medication overdose.
Significant intoxication or dangerous withdrawal.
Severe reduction in eating or drinking.
Significant self-neglect.
Safeguarding concerns.
Abuse or exploitation.
Acute physical health concerns.
Significant concerns about capacity or consent.
A behaviour-change issue that requires specialist treatment outside your competence.
Any situation where the patient cannot safely participate in a routine motivational conversation.
You might still communicate empathically.
But the priority becomes:
Safety.
Assessment.
Appropriate clinical action.
5. Summary
Motivational interviewing is a collaborative approach to conversations about change.
It is particularly useful where someone is ambivalent.
Ambivalence means:
“I want to change.”
AND:
“I have reasons not to.”
MI does not attempt to defeat one side through argument.
It helps the person explore both sides and strengthen their own reasons for change.
The spirit of MI involves:
Partnership.
Acceptance.
Compassion.
Evocation.
The four broad processes are:
Engaging.
Focusing.
Evoking.
Planning.
Core communication skills can be remembered as OARS:
Open questions.
Affirmations.
Reflections.
Summaries.
Listen for change talk:
Desire.
Ability.
Reasons.
Need.
And later:
Commitment.
Activation.
Taking steps.
Do not attack sustain talk.
Explore it.
Avoid the righting reflex.
Ask before advising.
Use the person’s goals and values.
Support realistic next steps.
Remember the MOTIVATE framework:
Meet the person where they are.
Open up ambivalence.
Tune in to change talk.
Invite their own reasons.
Validate autonomy.
Ask before advising.
Turn motivation into a small step.
Escalate when safety requires it.
The central principle is:
You cannot force genuine motivation into someone.
But you can create a conversation in which they are more able to discover, hear and strengthen their own reasons for change.

NICE CG115: Alcohol-Use Disorders
NICE recommends motivational intervention as part of the initial assessment for people who misuse alcohol.
The guidance specifically describes helping people recognise alcohol-related problems, explore and resolve ambivalence, encourage belief in the ability to change and adopt a supportive rather than argumentative or confrontational approach.
This is one of the clearest NICE examples of motivational interviewing principles being incorporated into routine clinical care.
NICE CG51: Drug Misuse in Over 16s – Psychosocial Interventions
NICE recommends brief motivational interventions in appropriate drug-misuse settings.
These interventions are designed to explore ambivalence about drug use and treatment, strengthen motivation for change and provide non-judgemental feedback.
NICE also states that interventions should be delivered by staff who are competent and appropriately supervised.
NICE QS23: Drug Use Disorders in Adults
This quality standard describes psychosocial interventions delivered by keyworkers and distinguishes these from more formal psychological interventions requiring defined competencies, training and supervision.
This is especially relevant to the case worker role.
NHS England Mental Health Personalised Care Framework
The 2026 Mental Health Personalised Care Framework emphasises care based on what matters to the individual, their strengths, needs and aspirations.
It describes people as active participants in shaping their care rather than passive recipients of professional decisions.
These principles strongly complement motivational interviewing.
NHS England Personalised Care and Support Planning
NHS England describes personalised care planning as a series of facilitated conversations in which people actively participate in identifying goals and actions that make sense within their whole life.
The approach emphasises listening, shared goals, strengths, skills and building confidence and control.
Key Research: Motivational Interviewing for Substance Use
Schwenker R and colleagues. Motivational interviewing for substance use reduction. Cochrane Database of Systematic Reviews. 2023.
This updated Cochrane review included 93 studies and 22,776 participants.
The evidence suggests that MI can improve some substance-use outcomes compared with certain control conditions, although effects vary depending on outcome, comparator and follow-up period and the evidence is not uniformly strong.
This is an important reminder not to present MI as universally effective for every person or problem.
Motivational Interviewing and Mental Health Treatment Engagement
Lawrence P and colleagues. Motivational interviewing to enhance treatment attendance in mental health settings: a systematic review and meta-analysis.
The review found that MI used before treatment improved subsequent treatment attendance compared with control conditions, with people who were initially less motivated to seek mental healthcare appearing to benefit particularly.
Motivational Interviewing in Broader Mental Health Problems
Romano M and Peters L. Evaluating the mechanisms of change in motivational interviewing in the treatment of mental health problems: a review and meta-analysis.
This review examined MI across mood, anxiety, psychotic, eating and comorbid disorders.
It found some evidence that engagement may be one mechanism through which MI contributes to treatment, while also highlighting substantial variation between studies and limitations in the evidence base.

7. Knowledge Check
Question 1
Which statement best describes motivational interviewing?
A. A method for persuading patients to follow professional advice.
B. A collaborative approach that helps strengthen a person’s own motivation and commitment to change.
C. A technique for challenging irrational thoughts.
D. A method of giving detailed information about the risks of unhealthy behaviour.
Correct answer: B.
Motivational interviewing helps people explore ambivalence and strengthen their own reasons for change.
Answer A confuses MI with persuasion.
Answer C is more consistent with some cognitive approaches and does not define MI.
Answer D may be part of a wider conversation but information-giving alone is not motivational interviewing.
Question 2
A patient says:
“I know drinking is making things worse, but it’s the only way I can relax.”
What does this statement best demonstrate?
A. Lack of insight.
B. Ambivalence.
C. Psychosis.
D. Treatment refusal.
Correct answer: B.
The patient is simultaneously describing a reason to change and a reason to maintain the current behaviour.
That is ambivalence.
Answer A is incorrect because the person clearly recognises some negative effects.
Answers C and D are not supported by the statement.
Question 3
What is the “righting reflex”?
A. The patient's attempt to resist treatment.
B. The practitioner’s urge to correct a problem and tell the person what they should do.
C. The ability to identify change talk.
D. A technique for summarising ambivalence.
Correct answer: B.
Healthcare professionals naturally want to fix problems.
In MI, repeatedly acting on this urge can lead the practitioner to argue for change while the patient argues against it.
Answer A incorrectly locates the process in the patient.
Answers C and D describe other MI skills.
Question 4
Which of the following is an example of change talk?
A. “Alcohol is the only thing that helps.”
B. “I don’t think cannabis causes any problems.”
C. “I want to cut down because I’m worried about losing my job.”
D. “Everyone else thinks I should stop.”
Correct answer: C.
The patient is expressing both desire and a reason for change.
Answers A and B are examples of sustain talk.
Answer D reports other people’s motivation rather than necessarily expressing the patient’s own reason for change.
Question 5
A patient rates the importance of reducing alcohol as 6 out of 10.
Which question is most likely to evoke change talk?
A. “Why isn’t it a 10?”
B. “Why is it a 6 rather than a 3?”
C. “You obviously don’t think it is very important, do you?”
D. “Shouldn’t it be higher?”
Correct answer: B.
Asking why the rating is higher than a lower number invites the person to explain what makes change important.
Answer A encourages discussion of why change is not more important and may evoke sustain talk.
Answers C and D are judgemental and leading.
Question 6
What does OARS stand for?
A. Open questions, Advice, Reassurance and Safety.
B. Observation, Assessment, Reflection and Summary.
C. Open questions, Affirmations, Reflections and Summaries.
D. Options, Actions, Risk and Support.
Correct answer: C.
OARS describes four important MI communication skills:
Open questions.
Affirmations.
Reflections.
Summaries.
The other options contain potentially useful clinical concepts but do not describe the OARS framework.
Question 7
A patient says:
“I hate taking medication, but I really don’t want to end up in hospital again.”
Which response is most consistent with motivational interviewing?
A. “Then you obviously need to take the medication.”
B. “You’re wrong to stop it.”
C. “Part of you dislikes taking medication, while another part is frightened about becoming unwell again.”
D. “Medication is your only option.”
Correct answer: C.
The response reflects both sides of the patient's ambivalence.
Answer A jumps directly to the practitioner’s conclusion.
Answer B is confrontational.
Answer D may be clinically inaccurate and ignores the patient’s perspective.
Medication decisions should be discussed with an appropriately qualified clinician.
Question 8
Which statement best describes sustain talk?
A. Language expressing reasons for keeping things as they are.
B. Evidence that a patient is deliberately refusing treatment.
C. Language demonstrating commitment to change.
D. A reason to end motivational interviewing.
Correct answer: A.
Sustain talk reflects the side of ambivalence that favours the current behaviour.
It should usually be explored rather than confronted.
Answer B makes an unsupported judgement.
Answer C describes change talk.
Answer D is incorrect because sustain talk is a normal part of many motivational conversations.
Question 9
A practitioner wants to give a patient information about how cannabis may affect paranoia.
Which approach is most consistent with motivational interviewing?
A. Give a lengthy lecture explaining all the risks.
B. Tell the patient they must stop.
C. Ask what they already know, offer relevant information with permission and then ask what they make of it.
D. Avoid giving any information because MI prohibits advice.
Correct answer: C.
This reflects an Elicit–Provide–Elicit approach.
First understand what the person knows.
Then provide relevant information.
Then return to their perspective.
Answer A may overwhelm or provoke defensiveness.
Answer B is directive.
Answer D is incorrect because MI does not prohibit information or advice.
Question 10
During a motivational conversation about alcohol, a patient says:
“I don’t care about the drinking anymore. I’ve decided I’m going to take all my tablets tonight.”
What should the case worker do?
A. Explore the advantages and disadvantages of suicide.
B. Continue motivational interviewing until the patient expresses change talk.
C. Recognise a significant safety concern and initiate urgent clinical escalation.
D. Ask the patient how confident they are from 0 to 10 that they will change their mind.
Correct answer: C.
The conversation has moved from routine ambivalence about behaviour change to an acute safety concern.
Urgent clinical assessment and escalation take priority.
Answer A would be inappropriate and unsafe.
Answer B delays necessary clinical intervention.
Answer D misuses a motivational technique in a situation requiring immediate risk management.
The central lesson is:
Motivational interviewing is not about finding a clever way to make people do what we want.
It is about creating the conditions in which people can hear themselves think.
Listen for both sides of ambivalence.
Resist the urge to argue.
Draw out the person’s own reasons for change.
Support autonomy.
Build confidence.
And when the person is ready, help translate motivation into a realistic next step.
Sometimes the most powerful question is not:
“How can I convince you?”
It is:
“What would make change worth it to you?”
