An Introduction to Motivational Interviewing

Motivational interviewing is a communication approach where a coach helps a client work through ambivalence toward behavioral change. It is highly effective for people who are ambivalent about change.

Motivational interviewing was first described more than 40 years ago, when it was used and studied as a tool to help alcoholics quit drinking. Since then, its efficacy with regard to a wide range of behavior changes has been proven through hundreds of scientific research studies (reviewed in Miller & Rollnick 2012). Without a doubt, this communication approach helps people who are ambivalent move toward change. Fitness professionals who gain some degree of proficiency in motivational interviewing will see immediate value.

It generally proceeds through four phases:

Engaging. The coach and client develop a strong, open relationship.

Focusing. The client and coach establish and/or explore the focus of the relationship. In many cases the focus will be apparent; however, if it isn’t, coaches may use “agenda mapping,” during which they explore several possible areas of focus and the client chooses one.

Evoking. The coach asks questions and provides reflections to help the client verbalize reasons for change through “change talk.” The coach helps the client to increase his motivation for change by reflecting on change talk, which typically comes up in the form of “DARN” statements: desire, ability, reasons or need to change.

Planning. The client and coach develop an action plan for behavioral change.
Not every session will proceed through all four phases. In fact, the people who benefit most from motivational interviewing—those ambivalent about change-— will take awhile to get to the planning phase.

Miller & Rollnick (2013) recommend the following when you are first learning motivational interviewing.

  1. Why do you want to make this change?
  2. How might you go about making this change?
  3. What are the three best reasons for you to do it?
  4. How important is it for you to make this change?
    After each question, reflect on the client’s responses and summarize them,
    before asking:
  5. So what do you think you’ll do?

There are many opportunities to gain motivational interviewing skills, though
the most effective is through ongoing practice and feedback. The Motivational Interviewing Network of Trainers (MINT), at www.motivationalinterviewing.org, offers workshops, some of which founders William R. Miller and Stephen Rollnick lead. The American Council on Exercise offers a Behavior Change Specialty certification. Wellcoaches® offers motivational interviewing in its coach training curriculum. Miller and Rollnick’s book Motivational Interviewing: Helping People Change (2012) provides a thorough introduction, along with prompts to support skill development.
