|Obsessive-Compulsive Disorder||Drug: Risperidone Behavioral: Exposure/ritual prevention therapy (EX/RP) Drug: Placebo|
|Study Design:||Allocation: Randomized
Intervention Model: Factorial Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
|Official Title:||Maximizing Treatment Outcome in OCD|
- Score on the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) [ Time Frame: Week 0 and Week 8 ]Y-BOCS ranges from 0-40, with 0 meaning no symptoms and higher numbers meaning greater symptom severity
- Social Adjustment Scale-SR [ Time Frame: Week 0 and Week 8 ]SAS-SR yields a mean score between 1 and 5; the higher the score, the more severe the social adjustment problems
- Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form [ Time Frame: Week 0 and Week 8 ]QLESQ ranges from 14-70, with higher scores meaning more enjoyment and satisfaction with quality of life
- Hamilton Depression Rating Scale (Ham-D) [ Time Frame: Week 0 and Week 8 ]Ham-D ranges from 0=no symptoms to 52 with higher numbers indicating more severe depression
- Brown Assessment of Beliefs (BABS) [ Time Frame: Week 0 and Week 8 ]Scale ranges from 0 to 24 where 0 is "beliefs are false" and 24 is "convinced beliefs = reality"

Active Comparator: 1
Participants will receive treatment with risperidone
Dosage of 0.5 mg to 4.0 mg per day as tolerated
Other Name: Risperdal
Active Comparator: 2
Participants will receive exposure and ritual prevention therapy (EX/RP)
Behavioral: Exposure/ritual prevention therapy (EX/RP)
EX/RP is a form of cognitive behavioral therapy. Participants assigned to EX/RP will attend therapy sessions twice per week. In EX/RP, participants will be exposed to feared objects or ideas, and will be encouraged not to carry out a compulsive response.
Other Name: EX/RP
Placebo Comparator: 3
Participants will receive treatment with the placebo
Placebo capsules will be identical in appearance to those of risperidone.
Other Name: PBO
Obsessive-compulsive disorder (OCD) is a common psychiatric illness. People with OCD experience unwelcome thoughts, known as obsessions, and feel compelled to perform repetitive behaviors, or compulsions. Impairment due to OCD symptoms ranges from mild to severe, and sometimes can be disabling. The only medications proven effective for OCD are serotonin reuptake inhibitors (SRIs), but even with SRI treatment, most patients continue to experience significant OCD symptoms, impaired functioning, and diminished quality of life. Cognitive-behavioral therapy (CBT), a talking therapy that focuses on altering a person's thoughts and behaviors, and the medication risperidone have both been commonly used for augmenting SRI treatment for OCD. This study will compare the short- and long-term effectiveness of exposure and ritual prevention (EX/RP), a type of CBT, and risperidone in augmenting SRI treatment in people with OCD.
Participants in this double-blind study will be randomly assigned to receive EX/RP, risperidone, or placebo in conjunction with their regular SRI medication. All participants will remain on their regular SRI at a stable dose. During the first 2 months of the study, participants assigned to EX/RP will attend therapy sessions twice per week. In EX/RP, participants will be exposed to feared objects or ideas, and will be encouraged not to carry out a compulsive response. Participants assigned to risperidone or placebo will meet with a psychiatrist once every 1 to 2 weeks. At the end of 8 weeks, all participants' OCD symptom severity will be assessed. During this time, participants who have responded to treatment will continue receiving the same treatment for an additional 24 weeks. Participants assigned to EX/RP will meet with a therapist no more than 15 times total, and participants receiving risperidone or placebo will meet with a psychiatrist once every 4 weeks. Outcomes will be reassessed at study completion.
