Motivational Interviewing: the method, the errors, and the exam
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
Motivational interviewing is a patient-centred technique for exploring ambivalence about behaviour change, built on rolling with resistance and developing discrepancy. The patient states their own reason to change; the nurse never argues for it. On the exam and at the bedside, any answer where the nurse pushes, persuades or lectures is the wrong one.
What the skill is for
Motivational interviewing exists for the exact situation where lecturing fails: a patient who knows the health facts already but hasn't decided to act on them. Telling a smoker that smoking causes lung disease rarely changes behaviour, because the patient usually knows that already. What's missing isn't information, it's the patient's own reason to change, spoken in their own words.
It's used most in chronic disease management, substance use, weight and lifestyle counselling, and medication adherence, wherever a patient has to choose a harder path repeatedly over months or years rather than agree to a one-time procedure. The nurse's job shifts from persuader to a kind of interviewer who helps the patient hear their own ambivalence out loud.
The method, step by step
Start by expressing empathy without judgement — acknowledge that change is hard before you talk about the change itself. Then roll with resistance: if the patient pushes back or defends the status quo, don't argue the counterpoint. Reflect the resistance back neutrally, which tends to defuse it, whereas arguing tends to entrench it.
The central technique is developing discrepancy — helping the patient notice the gap between where they are and where they say they want to be, without the nurse naming that gap for them. Ask about their goals first, then ask how the current behaviour fits with those goals, and let the patient draw the connection. Close by supporting self-efficacy: reinforce that the patient has changed things before and can do it again, using a specific example from their own history if you have one.
Where it goes wrong
The most common failure is the 'righting reflex' — the nurse's instinct to correct the patient and argue the case for change directly. 'You really need to quit smoking, it's damaging your lungs' is clinically true and motivationally counterproductive, because it puts the nurse on one side of the argument and the patient on the other, defending their behaviour by reflex.
A second failure is treating resistance as something to overcome rather than something to roll with — pushing harder when a patient pushes back only strengthens their case for staying the same. A third is skipping straight to a plan before the patient has voiced any of their own reason to change, which produces a plan the patient never actually owns and rarely follows through on.
Practising it deliberately
The hardest habit to build is staying quiet when a patient says something factually wrong or self-defeating about their condition. Practise catching the urge to correct them and asking a question instead: 'What do you think happens if you keep going the way things are now?'
Rehearse developing discrepancy specifically, since it's the piece most nurses skip under time pressure. Take a patient statement like 'I know I should exercise more' and practise following it with a question that surfaces their own gap — 'What would it mean for you if you were able to?' — rather than supplying the answer yourself.
Applying it on the exam
NCLEX items testing motivational interviewing usually present a patient who is ambivalent or resistant about a health behaviour, with answer options ranging from direct persuasion to open-ended exploration. The correct answer is consistently the one that asks the patient to state their own view rather than the one that states the clinical case for change, no matter how accurate that case is.
Watch for options where the nurse argues, corrects, or lists consequences — these test the righting reflex the technique is built to avoid, and they're the distractor. The right answer typically reflects the patient's ambivalence back to them or asks what change would mean to them personally.
A worked example
A patient with type 2 diabetes and an A1C of 9.2% says, 'I know I should watch my diet better, but it's just really hard with my schedule.' A poor response: 'It's important that you manage your diet, otherwise your blood sugar will keep climbing.' That's the righting reflex, and it argues a case the patient already knows.
A better response: 'It sounds like part of you wants to make changes and part of you finds it hard to see how, with everything else going on.' That reflects the ambivalence without resolving it for the patient. If they respond by describing what better control would let them do — see grandchildren grow up, avoid complications a parent had — that's the patient developing their own discrepancy, and the nurse's job is to reflect it back, not add to it.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our psychosocial integrity practice questions are the closest set to what this page covers.
One question from the psychosocial integrity set
A client admitted with major depressive disorder tells the nurse, "Everyone would be better off without me." Which response is most appropriate?
Rationale
Ask directly. Asking about suicide does not plant the idea, and a veiled statement like this one has to be converted into an assessable answer before anything else happens — including exploring feelings. Reassurance dismisses the statement, deferring to group delays a safety assessment, and 'what made you feel this way' is a therapeutic question in the wrong order: safety first, then exploration.
Answer: B
Common questions
How is motivational interviewing different from patient education?
Patient education transfers information the patient may not have. Motivational interviewing assumes the patient already has the information and instead explores their own ambivalence about acting on it. The two are often used together, but they solve different problems.
What does 'rolling with resistance' actually mean in practice?
It means not arguing when a patient defends their current behaviour. Instead of countering their point, reflect it back neutrally — 'it sounds like cutting back feels unrealistic right now' — which tends to reduce defensiveness rather than increase it.
Can motivational interviewing be used in a short bedside encounter, or does it need a dedicated session?
It can be used in a few minutes. A single well-placed open question about the patient's own goals, followed by genuine listening, captures the core of the technique even without a full structured session.
Why is 'develop discrepancy' the part nurses tend to skip?
It requires patience and restraint — waiting for the patient to notice the gap between their goals and their behaviour, rather than pointing it out directly. Under time pressure, it's faster to just state the gap yourself, which is exactly the move that undermines the technique.
