This randomized controlled study (n= 40) examined the effect of a three-session motivational interviewing (MI) intervention compared to a three-session relaxation intervention prior to 15 sessions of ERP on treatment dropout, homework compliance, and treatment outcome post-ERP and at follow up. Contrary to hypotheses, there were no group differences in ERP dropout rates or homework compliance. Both groups experienced significant reductions in OCD symptoms post-ERP. Consistent with our hypothesis, the MI group experienced a greater reduction in OCD symptoms (clinician-rated YBOCS) compared to the comparison group immediately post-ERP. However, this difference did not hold over 12-month follow up. There were also no group differences in associated symptoms (depression, anxiety, stress) across treatment. All participants achieved significant symptom reductions that were maintained over time. A correlational analysis of the whole sample revealed that action scores pre-ERP were significantly negatively correlated with post-ERP OCD sympt...
