Title: D-Cycloserine Enhancement of Exposure in Social Phobia
Brief Summary: The purpose of this study is to test a drug called d-cycloserine to see if it can help people with a condition called social phobia. Social phobia is also called "social anxiety disorder." Social phobia is a constant fear of social or performance situations. Social situations include group gatherings of any kind. Performance situations might include times when a person would have to do something in public, such as speak up in class or at a meeting. A person with this condition worries about being embarrassed, or about other people's opinions. People with social phobia usually feel extremely anxious (nervous and worried) about being the focus of attention. They often avoid social and performance situations. This behavior can have a negative effect on the quality of their lives and relationships.

In this study, we want to find out if d-cycloserine can help control social phobia when the drug is added to the standard treatment for this condition. The standard treatment is cognitive-behavior therapy (CBT). CBT is a form of talk therapy involving discussion with a therapist, along with practicing the feelings or events that the person finds frightening.
