What Is… Motivational Interviewing

Motivational interviewing fundamental principles and tools

In this series, I dig a little deeper into the meaning of psychological terms.  This week’s term is motivational interviewing.

Motivational interviewing (MI) is a therapeutic communication approach.  It’s often used in the field of addictions, but it’s got some very useful tidbits that are more broadly applicable to motivation for any sort of change.  It also has some helpful hints on how the way we talk to people can push them towards or away from change.

Change and sustain talk

The fundamental idea is that there is always some ambivalence regarding any potential change that’s being considered.  The way you talk to someone about the issue can elicit “change talk”, which comes from the side of their ambivalence that favours change, or it can elicit “sustain talk”, which comes from the anti-change side of their ambivalence.  If you can get the other person talking about what’s wrong with sustaining and what might be good about changing, it helps to strengthen their motivation to change.  The key is to get them talking about it, rather than you telling what you think.

In a post I wrote recently about effective anti-stigma campaigns, I mentioned the idea of psychological reactance; if you tell someone what to do, their natural tendency is to resist it.  Motivational interviewing uses this same concept, and takes the stance that if you argue that change is good, the other person will then take the opposite stance and argue that change is bad (sustain talk).  That can be harder than it sounds, and in clinical practice, a lot of supervision is involved to make sure that the natural “righting reflex” is kept firmly in check.

Fundamental principles

Motivational interviewing uses a lot of acronyms for key concepts.  The fundamental principles of MI are DARES:

  • Develop Discrepancy: help the person see the discrepancy between where they are now and where they want to be with their lives
  • Avoid Argumentation: if you argue for something, the other person will end up arguing again it
  • Roll with Resistance: pushing back against the other person’s resistance will only strengthen it
  • Express Empathy: this includes validating how the other person is feeling
  • Support Self-efficacy: empower the individual to create change themselves

Use your OARS

Important communication tools, especially early in the process, are OARS:

  • Open-ended questions
  • Affirmations
  • Reflection
  • Summaries

What prompts change

MI identifies a number of different catalysts for change:

  • consciousness raising: increasing knowledge about the problem; information should be provided from a neutral stance rather than trying to be persuasive
  • self-reevaluation: considering the self in relation to the problem behaviours
  • self-liberation: making a commitment to change or believing in one’s own ability to change
  • counterconditioning: substituting alternative coping mechanisms for anxiety that’s related to the problematic behaviour
  • stimulus control: avoiding or coming up with a way to counter stimuli that trigger the problem behaviour
  • reinforcement management: rewarding positive change
  • environmental reevaluation: assessing how problem behaviours affect the personal and physical environment

Tools used in motivational interviewing

Decisional balance grids, which lay out pros and cons for both changing and not changing, are a common tool used in MI.  Readiness rulers are also used to rate one’s readiness, willingness, and ability to change on a scale of 1 to 10.    Discussions around these tools focus on eliciting change talk.  Let’s consider an example where someone marked their ability to change as a 4 out of 10.  Asking why they didn’t score higher is likely to elicit sustain talk.  On the other hand, asking why they didn’t score lower is probably going to elicit change talk.

Another strategy is asking about extremes.  You might ask the person why the problem hasn’t reached a greater extreme than it already has.  Exploring goals and values can play an important role.  Past successes can be explored to enhance a sense of self-efficacy.

MI incorporates the transtheoretical model of change, which includes several stages with respect to making a change: precontemplation (not considering change yet), contemplation, preparation, action, maintenance, and relapse/recurrence.  Different strategies are recommended to meet the individual where they’re at in terms of the stages of change.

You can’t make someone change

The whole sneaky idea is to get the person to talk themselves into change.  It totally turns the table on our natural inclination to convince people they should make positive change and tell them how we think they should do it.  In MI, “resistance” to change is reframed as the interviewer (for lack of a better word) pushing too hard, and at that point, the interviewer needs to back off and return to using OARS (as outlined above).  

If the person is leaning towards the sustain side, the interviewer needs to consider whether that could be, at least in part, a natural reaction to the interviewer pushing the change side of the equation.

Is there a situation where you think some of these tactics might have been helpful in dealing with another person’s problematic behaviours?

  1. This was SUPER informative. Thank you. I kept hearing the phrase, but had honestly not looked into it. This makes me want to learn more. ๐Ÿ˜Š

  2. That is so freakin’ interesting. I’ve always wondered what made therapists tick (and what they were trained to do), and here you are shining a light on it.

    It all seems rather manipulative to me, but on the other hand, if someone were at war with him/herself and wanted to change but wasn’t feeling strong enough to change, I can see how this would help.

    Very informative!!!! I think you could write an article for one of those sites about this!!

    1. It does seem manipulative since it’s kind of sneaky, but it’s really not about planting ideas in someone’s head – its about fleshing out what’s already there.

  3. This is so cool! I think this could be useful in how I talk to myself, actually, especially when Iโ€™m trying to convince myself to not do crisis behaviors.
    The therapist I had over the summer tried to convince me to do Prolonged Exposure therapy for my PTSD, and the way she tried to do it kinda backfired. I only became committed to exposures when she stopped trying to convince me. This explains why! Thank you!
    Also, I like your blog index! ๐Ÿ™‚ Is that new?

  4. Iโ€™m currently studying to become a professional life coach and a lot of what you mention is a huge part of my studies. I am a huge believer that we often already know the answer, we just need to someone to ask the right questions to help us expand our thinking ๐Ÿ˜Š This was a great read! ๐Ÿ˜Š
