  Purpose

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.

Primary Outcome Measures:
  • Penn State Worry Questionnaire (PSWQ) [ Time Frame: up to 4 years ] [ Designated as safety issue: No ]
    The Penn State Worry Questionnaire (PSWQ; Meyer et al., 1990) is a widely used measure of worry in GAD treatment outcome studies. It is a 16-item scale assessing trait worry. The PSWQ has been found to possess high internal consistency and temporal stability, as well as good convergent and discriminant validity. It also differentiates individuals with GAD from those with other anxiety disorders (Brown et al., 1992).


Secondary Outcome Measures:
  • Satisfaction with Life Scale (SWLS) [ Time Frame: up to 4 years ] [ Designated as safety issue: No ]
    The Satisfaction with Life Scale (SWLS; Diener et al., 1985)is a 5-item scale that is a widely used as a measure of life satisfaction with high internal validity, temporal stability, and sensitivity to change, as well as good convergent and divergent validity.

  • Inventory of Interpersonal Problems (IIP) [ Time Frame: up to 4 years ] [ Designated as safety issue: No ]
    The Inventory of Interpersonal Problems (IIP; Horowitz, Rosenberg, Baer, Ureño, & Villaseñor, 1988), scale has been shown to discriminate among different categories of personality disorders and reliably tap into three dimensions of the the interpersonal relational field (Gude, Moum, Kaldestad, & Friis, 2000).

  • Depression Anxiety Stress Scale (DASS) [ Time Frame: up to 4 years ] [ Designated as safety issue: Yes ]
    The Depression Anxiety Stress Scale (DASS; Lovibond & Lovibond, 1995) is a set of three self-report scales designed to define, measure and understand depression, anxiety and stress. Each scale contains 14 items, for a total of 42 items, and each scale is divided into sub-scales of 2-5 items based on content. The DASS shows strong consistent reliability in distinguishing between features of depression, anxiety and stress (Antony, Bieling, Cox, Enns, Murray & Swinson, 1998).

Arms Assigned Interventions
Active Comparator: MI-CBT 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.
