Primary Outcome Measures:
  • Yale-Brown Obsessive Compulsive Scale (YBOCS) [ Time Frame: Post-treatment (week 5) ] [ Designated as safety issue: No ]
    A clinician-rated measure of obsessive-compulsive disorder severity. Each item is scored on a 0 to 4 range. Total scores are obtained by summing items 1-10 and thus range from 0 to 40 with higher scores indicating greater symptom severity. Results posted below are from the post-treatment evaluation (after 10 treatment sessions).

Secondary Outcome Measures:
  • Clinical Global Impressions Scale (CGI) [ Time Frame: Post-treatment (week 5) ] [ Designated as safety issue: No ]
  • Beck Depression Inventory (BDI) [ Time Frame: Post-treatment (week 5) ] [ Designated as safety issue: No ]
  • Beck Anxiety Inventory (BAI) [ Time Frame: Post-treatment (week 5) ] [ Designated as safety issue: No ]
  • Obsessional Beliefs Questionnaire (OBQ) [ Time Frame: Post-treatment (week 5) ] [ Designated as safety issue: No ]
  • Short-Form Health Survey (SF-36) [ Time Frame: Post-treatment (week 5) ] [ Designated as safety issue: No ]
  • Disability Inventory [ Time Frame: Post-treatment (week 5) ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Active Comparator: Seromycin Drug: seromycin
100mg tablet administered 1 hour prior to each therapy session

Detailed Description:

We hope to enroll 50 subjects in a double-blind, placebo-controlled study of D-cycloserine augmentation of behavior therapy for Obsessive-Compulsive Disorder. All subjects will undergo a pre-treatment assessment, and then be randomly assigned to receive Seromycin (100 mg) or placebo one-hour before each of 10 therapy sessions. Subjects will then come in for a treatment planning session and the behavior therapy sessions delivered twice weekly for 5 weeks. Comprehensive assessments of obsessive-compulsive symptoms, mood state, and cognitions will be given at baseline, after 5 treatment sessions, after 10 sessions and 1 month and 6 months post-treatment.
