Abstract

Cognitive-behavioral therapy (CBT) is the psychological treatment of choice for panic disorder (PD). However, given limited access to CBT, it must be delivered with maximal cost-effectiveness. Previous researchers have found that a brief computer-augmented CBT was as effective as extended therapist-delivered CBT. To test this finding, this study randomly allocated 186 patients with PD across 2 sites in Scotland and Australia to 12 sessions of therapist-delivered CBT (CBT12), 6 sessions of therapist-delivered (CBT6) or computer-augmented CBT (CBT6-CA), or a waitlist control. On a composite measure, at posttreatment, the outcome for CBT 12 was statistically better than the outcome for CBT6. The outcome for CBT6-CA fell between CBT12 and CBT6, but could not be statistically distinguished from either treatment. The active treatments did not differ statistically at 6-month follow-up. The study provided some support for the use of computers as an innovative adjunctive-therapy tool and merits further investigation.
