Summary:

      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.
