Integrating motivational interviewing (MI) techniques into the commonly practiced cognitive behavioral therapy (CBT) is the ideal option for treating anxiety, a study led by York University research reveals.

Motivating willingness to change is important in treating a person with severe worry, and the study shows blending therapies improves the treatment of anxiety.
“Our research shows that therapists need to have two sets of skills – to help people become ready for change, and then to help them accomplish that change,” says Henny Westra, a psychology professor in the Faculty of Health at York U. “The study results suggest that integrating motivational interviewing (MI) with CBT is more effective than CBT alone for long-term improvement.”
It is normal to feel conflicted about change, and motivational interviewing is an approach therapists can use to help patients understand and validate the fear of change. It offers a patient-centered way of helping individuals work through their conflicting feelings in order to enhance motivation for change.
“Because MI is focused on listening and drawing out client ideas, patients feel more confidence in coping with issues facing them even after therapy ends, in contrast to having to rely on the therapist’s expertise,” says Westra, who led the study with Ryerson University Professor Martin Antony and Professor Michael Constantino, University of Massachusetts Amherst.
The five-year study was conducted with grant support from the Canadian Institutes of Health Research (CIHR). During the randomized clinical trial, 85 participants underwent treatment for severe generalized anxiety disorder (GAD). Cognitive behavioral therapy alone was given to 43 participants and the rest received a combination of CBT and MI from therapists trained in both.
Although the participants responded well to both the motivationally enhanced CBT and standard CBT during the 15-week treatment phase, the results indicate those who received the motivationally enhanced treatment continued to improve. Those in the MI-CBT were five times more likely to be free of the diagnosis of generalized anxiety one year after treatment ended.
“This study highlights the importance of studying the long-term impact of our treatments, as the enhanced improvements seen in people who received the integrated MI and CBT treatment were greatest sometime after treatment had ended,” says Antony.
The study titled “Integrating Motivational Interviewing with Cognitive-Behavioral Therapy for Severe Generalized Anxiety Disorder: An Allegiance-Controlled Randomized Clinical Trial” is published online in the Journal of Consulting and Clinical Psychology.
