Social anxiety disorder is a prevalent and disabling condition for which effective long-term treatments need to be identified. Paroxetine is effective in treating the acute symptoms of social anxiety, but many patients achieve less than optimal response. CBT has also been effective in treating social anxiety disorder; thus,it may also be effective in augmenting paroxetine response. This study will examine the effects of paroxetine treatment alone and in combination with CBT among patients who achieve less than optimal response after an open trial with paroxetine.~Participants in this study will receive paroxetine for 12 weeks (Phase 1). After 12 weeks, participants who have completed this open trial but have achieved some but less than optimal response will move forward to Phase 2. To be eligible to move forward to Phase 2, patients must have achieved at least a 10% improvement in their open-trial Liebowitz Social Anxiety Scale Scores (LSAS) but still have an LSAS score of 30 or greater. Patients meeting these criteria will be randomly assigned to either add weekly sessions of CBT to their treatment or to continue taking paroxetine alone for another 16 weeks. Social anxiety symptoms, rates of response and remission, fear of negative evaluation, disability and quality of life will be assessed.
This study will examine whether the addition of cognitive behavioral therapy can improve the efficacy of the medication paroxetine (Paxil®) in treating individuals with social anxiety disorder. Patients with social anxiety disorder will undergo a 12-week open trial with paroxetine. Those who complete the open trial having achieved only partial response will be randomized to receive cognitive behavioral therapy (CBT) in addition to paroxetine or to continue on paroxetine alone for an additional 16 weeks.
