The primary aim of this study was to compare the effectiveness of Internet-and group administered CBT for panic disorder with or without agoraphobia in a randomised trial within a regular psychiatric care setting. The second aim of the study was to establish the cost-effectiveness of these interventions. Methods Patients referred for treatment by their physician or self-referred were telephone-screened by a psychiatric nurse. Patients fulfilling screening criteria underwent an in-person structured clinical interview carried out by a psychiatrist. A total of 113 consecutive patients were then randomly assigned to 10 weeks of either guided Internet delivered CBT n 53 or group CBT n 60 . After treatment and at a 6-month follow-up patients were again assessed by the psychiatrist blind to treatment condition. Results Immediately after randomization 9 patients dropped out leaving 104 patients who started treatment. Patients in both treatment conditions showed significant improvement on the main outcome measure the Panic Disorder Severity Scale PDSS after treatment. For the Internet treatment the within-group effect size pre-post on the PDSS was Cohen s d and for the group treatment it was d . Between group effect sizes were low and treatment effects were maintained at 6-months follow-up. We found
