Motivational Interviewing Counsellors

How does motivational interviewing work?

Motivational interviewing aims to uncover a person’s internal motivation to change their life. Toward this end, the therapist listens, empathises, and collaborates with the client based on their perspective; the therapist doesn’t adhere to a predetermined plan for change or impose their viewpoint on the client. Discovering an individual’s most important reasons for change, and guiding them to achieve those changes, can empower people to shift from ambivalence to action.

Is motivational interviewing evidence-based?

Yes, research shows that motivational interviewing can help treat alcohol and substance use — and in different ways such as reducing drinking, reducing resistance, and increasing the likelihood of staying in treatment. Motivational interviewing has also been shown to help people lose weight, adhere to medication regimens, improve diet for those with Type II diabetes, and improve healthy behaviours in children.

How long does motivational interviewing last?

Motivational interviewing is a short-term therapy that can last just one or two sessions. In some cases, motivational interviewing may be used in conjunction with longer-term therapies, but for most people, motivational interviewing is a brief intervention that aims to help patients understand their personal, specific, and internal reasons for changing their life.

What differentiates motivational interviewing from person-centered therapy?

In person-centered therapy, the individual is in the driver’s seat of the treatment process, creating space for them to trust their instincts and arrive at their own solutions. The two approaches are similar because motivational interviewing is also client-centered; however, person-centered therapy is more open-ended while motivational interviewing is somewhat more structured; the goal is to change, and the therapist helps the client specifically discover their internal motivations to modify their behaviour.
