Abstract
OBJECTIVE
We examined the unique predictive strength of anxiety sensitivity (AS) and the role of expectancy, credibility, and therapeutic alliance (TA) as predictors and mediators of cognitive-behavioral treatment (CBT) outcomes in obsessive-compulsive disorder (OCD).
METHOD
The current study is a prospective cohort study. Participants (N = 116) were treatment-seeking individuals with a primary diagnosis of OCD. Independent raters assessed patients on Yale-Brown Obsessive-Compulsive Scale (YBOCS) and Anxiety Sensitivity Index-3 at baseline, post-intervention, and three-month follow-up. Participants responded to the Credibility and Expectancy questionnaire and Working Alliance Inventory-Short revised at baseline, first-session, and mid-session.
RESULTS
The individual addition of AS, end-of-first-session credibility and expectancy, mid-session credibility and expectancy, and therapeutic alliance predicted significant CBT outcomes. There was a moderate positive correlation between baseline OCD severity and the global score of AS, but a weak one with AS dimensions. Both expectancy and credibility significantly improved from baseline to end-of-first-session treatment. End-of-first and third-session outcome expectancies, not credibility, have significant, indirect effects on OCD CBT outcomes.
CONCLUSIONS
AS, within-session credibility and expectancies and TA independently predict CBT outcomes. Within-sessions outcome expectancies mediate CBT outcomes in OCD, not credibility. Expectancy and credibility both include state-like elements that can be influenced to enhance the outcomes of CBT. Proposals for reducing treatment barriers in CBT for OCD are offered.
