Intervention
All of the therapists had CBT training with
supervision. The training course included a four-day
workshop by David Westbrook, a director of the
Oxford Centre for Cognitive Behavioral Therapy. All of
the therapists were supervised by trained therapists at
least 12 sessions. The therapists developed a manual
for the present study. The patients met the therapist
for a CBT session every week and a session lasted one
hour. The maximum number of therapy sessions was
16. Completion of CBT treatment was defined as the
group of patients treated for at least eight sessions.
Every session of therapy was recorded with an MP3
recorder and randomly audited for adherence to the
manual. The doses of fluoxetine were fixed after study
commencement.
