Motivational Interviewing (MI) is an evidence-based psychotherapy used primarily in substance use disorders and in areas related to motivational change. MI is a collaborative, goal-oriented method of communication with a focus on the language of change. MI is used when the therapist wants to strengthen an individual’s motivation for a goal by eliciting and exploring the person’s own arguments for/against change. In MI, the therapist assumes a non-judgmental stance, acknowledges ambivalence, focuses on the patient's motivation for change, and also tolerates resistance to change. MI can also be integrated within other psychotherapies, such as cognitive behavioural therapy.
MI is an evidence-based treatment for alcohol use disorder, smoking, and other substance-use disorders.[1] There is also moderate evidence for its use in weight loss, blood pressure management, diabetes, and medication adherence.[2]
MI explores and resolving ambivalence, and centres on the motivational processes within an individual that facilitate change. This method differs from more “coercive” or externally-driven methods for motivating change. Thus, it does not impose change (that may be inconsistent with the person's own values, beliefs or wishes), but rather supports change in a manner congruent with the person's own values and concerns.
Several mmemonics below can be helpful to remember the core aspects of MI:

The spirit of MI can be remembered by the acronym DEARS
:
D
- Develop discrepancyE
- Express empathyA
- Amplify ambivalenceR
- Roll with resistanceS
- Support self-efficacy
There also needs to be a genuine value for the spirit of MI. The acronym PACE
can be used to remember this:
P
- Partnership (working together)A
- Acceptance (4’A’s, affirmation, autonomy, absolute worth, accurate empathy)C
- Compassion (caring about a person’s interest) E
- Evocation (bringing out a person’s wisdom rather than educating them)
The therapist needs to be proficient in client-centered interview skills. The mnemonic OARS
can be used to remember this:
O
- Open-ended questions (to explore depth and shift focus)A
- Affirmations (genuine statements about a person’s strengths, values, and efforts)R
- Reflections (strategic guesses about what the person just said, uttered by you as statements, which subtly influence what the person might say next)S
- Summaries (especially helpful in marking transitions in a conversation) Description | Example Statement | |
---|---|---|
Sustain Talk | Patient expresses why they cannot change or why they have to maintain the status quo | “I need to smoke at least a pack every day or I will not be able to function.” |
Change Talk | Patient expresses how making a change is something they want, are able to do, are committed to, need to do, or have already begun doing. | “I could try to smoke fewer cigarettes each day.” |
DARN
can be used to remember features of preparatory change talk:D
- Desire (e.g. - “I want to”)A
- Ability (e.g. - “I could”, “I'm able”)R
- Reasons (e.g. - “If… then”; “…because”)N
- Need (e.g. - “I have to”)CAT
can be used to remember features of mobilizing change talk:C
- Commitment (e.g. - “I will”, “I am going to”)A
- Activation (e.g. - “I'm considering”, “I'm willing to”)T
- Taking Steps (e.g. - “Last week I did”)There are structured tools to give observation-based feedback on the quality of MI given, including the Motivational Interviewing Treatment Integrity Code (MITI 4).[3]
