Given the high rates of treatment drop-out and non-compliance within empirically-based treatments for OCD, it is important to increase our understanding of factors that impact the treatment process. Two studies were conducted to evaluate the clinical utility of the Obsessive Compulsive Consequences Scale-Revised (OCCS-R) and increase understanding of the relationships between the prognostic factors of motivation, insight, treatment compliance and treatment outcome. Study 1 used maximum likelihood Confirmatory Factor Analysis to show the OCCS-R's four factor solution was an adequate fit in a sub-clinical college population. Study 2 evaluated the clinical utility of the OCCS-R for predicting treatment outcome and its relationship to identified predictor variables. The OCCS-R predicted treatment drop-out but did not predict symptom improvement. Some support was found for predicted relationships between the OCCS-R and its factors, a general measure of motivation and treatment compliance. No variables predicted symptom improvement. Insight and initial symptom severity predicted treatment motivation which in turn predicted treatment compliance.
