Summary

The current study examines whether change-readiness, and consequently treatment outcome, can be enhanced in Cognitive Behavioral Therapy (CBT) for severe Generalized Anxiety Disorder (GAD) by adding a brief course of Motivational Interviewing (MI adapted for anxiety, Westra \& Dozois, 2003) before and during CBT when motivation wanes. 106 individuals with severe GAD will be randomly assigned to receive an equal number of sessions of either MI and CBT (MI-CBT arm) or CBT alone (CBT alone arm). It is expected that the MI-CBT arm relative to the CBT alone arm will show lower levels of resistance in CBT, higher levels of homework compliance and therapeutic alliance, better moment-to-moment interpersonal process, and consequently superior outcomes - both post-treatment and at 6 and 12 month follow-ups.

BEHAVIORAL

Motivational Interviewing and Cognitive Behavioural Therapy

Participants with a diagnosis of severe Generalized Anxiety Disorder will be randomly assigned to receive either 4 weekly sessions of MI followed by 11 weekly sessions of CBT (MI-CBT arm) or 15 weekly sessions of CBT (CBT alone arm). Both groups will also receive 2 follow-up CBT treatment sessions at 1 and 3 months post-treatment. In order to increase generalizability to clinical practice, in the CBT phase for the MI-CBT arm, therapists will shift to MI in the presence of empirically derived markers of resistance and shift back to CBT when resistance has diminished. In the CBT alone arm therapists will respond to resistance using manualized recommendations derived from leading CBT theorists for the management of resistance.
