D-Cycloserine Enhancement of Exposure in Social Phobia

The patient will then receive 12 weekly sessions of Cognitive Behavioral Therapy lasting approximately two and a half hours each. During these sessions, patients will receive information on the nature of social phobia and a model of treatment and will receive weekly training in how to become more comfortable with social situations, with the goal of achieving confidence in social interactions. As part of this training, the therapist will practice social interactions with the patient, who will also be asked to practice what they have learned outside of the therapists' office.

For the third, fourth, fifth, sixth, and seventh sessions of the twelve-session program of Cognitive Behavioral Therapy, the patient will be asked to arrive one hour early to take one of the study pill, a 50mg pill of d-cycloserine. A physician will be available in the unlikely event that a patient begins to experience side effects. Before the treatment starts, before the eighth session, and one week after the final session patients will have a separate visit in which their levels of symptoms assessed with measures of mood, anxiety, and avoidance.
