About Motivational Interviewing


Motivational Interviewing (Miller & Rollnick, 2002) is a style of talking with clients in a constructive manner about the whys, whens, and hows of health-risk reduction and behavior change. Based upon the tenet that most individuals already have the requisite skills to successfully modify lifestyle and decrease health-risk, MI employs strategies that will enhance the client’s own motivation for and commitment to change. Motivational Interviewing integrates an empathic, non-confrontational style of interviewing with powerful behavioral strategies for helping clients convince themselves that they ought to change. Consequently, resistance is minimized, self-motivation enhanced, and treatment compliance and behavior change secured.

Motivational Interviewing provides an effective alternative to coercion, confrontation, and exhortation as a means of promoting behavior change and treatment compliance. With applications to a wide variety of health care concerns, Motivational Interviewing has been incorporated into the treatment of alcohol problems, tobacco use, weight control, diabetes management, cardiac rehabilitation, the control of chronic hypertension, and many other behavioral health care problems.

Motivational Interviewing is grounded in the following principles:

1. Motivation, or readiness to change, is better considered an ever-changing state rather than a static personality trait. The client is neither motivated nor unmotivated; in “denial” nor “surrendering;” more accurately, the interpersonal (e.g., clinical) situation and the activity of the health care provider serve to increase or decrease the client’s readiness to change. Readiness to change is an ever-changing product of the helping relationship.
2. Accordingly, the health care provider’s interviewing style determines, to a large extent, client readiness to change and, indeed, significantly impacts long-term behavior change. For example, Patterson & Forgatch (1985) were able to manipulate client resistance in a single interview just by switching between a confrontational and an empathic interviewer style. Miller, Benefield, & Tonigan (1993) found that a single feedback session varying only in empathic versus confrontational interviewer style resulted in different rates of alcohol use one year later; the empathic interviewers’ clients were drinking less than those of the confrontational interviewers.
3. Ambivalence regarding change is a normal aspect of the process of behavior change. This is true of all behavior, not just the behaviors of excess. Furthermore, there are almost always compelling reasons not to change.
4. It is only human to defend the other side of the ambivalence. If we argue for change, clients naturally will argue against change. The stronger we push for change, the more forcefully they will articulate the argument for staying the same. This is human nature. Impassioned arguments for change often undermine the clients’ investment in the change process.
5. To get clients to argue the case for adopting healthier lifestyles, we must understand, accept, and sometimes support the argument for not changing. Remember, the more we lecture, confront, or otherwise argue for change, the more “defensive” will become our clients.
6. People commit to change more readily when they have convinced themselves that they are better off changing. There is much truth to the idea that you can convince yourself of anything, if you just state your case thoroughly enough. Therefore, the ultimate goal of Motivational Interviewing is to create a situation in which clients persuade themselves to change, rather than having the health professional doing all of the persuasion.
7. Consistent with the active, client-centered approach, clients decide what behavior to focus upon and what health-risk reduction goals, if any, to set. Health care practitioners provide information and options, but leave decision-making to the client.
