Cost-Effectiveness of Adding Web-Based Cognitive-Behavioral Therapy (CBT) to Luvox CR for Obsessive Compulsive Disorder (OCD)

This study will test the hypotheses that: 1. 12 weeks of Luvox-CR plus web-based Cognitive-Behavioral Therapy (CBT) \[CT-STEPS\] will produce greater symptom relief of OCD than treatment with Luvox-CR alone; and, 2. subjects receiving 12 weeks of CT-STEPS added to Luvox-CR treatment after 12-weeks of Luvox-CR monotherapy will experience greater OCD symptom relief (from weeks 12-24) than those continuing Luvox-CR treatment and having access to CT-STEPS from week one. 3. subjects who begin CT-STEPS at week 12 will be more likely to complete it than those who begin CT-STEPS at baseline.
