Scientific title | A randomized, prospective, multicenter study of the effective treatments of panic disorder: cognitive behavioral therapy versus antidepressants versus combination therapy |
Study acronym | PD-study |
Study objectives | In the short-term, the combined treatment is expected to be superior to either mono-treatment. In the long-term, it is expected that cognitive behavioral therapy (CBT) will prove to be more durable and that patients taking selective serotonin reuptake inhibitor (SSRI) will require more mental health care during the one-year follow-up period. |
Ethics approval(s) | Not provided at time of registration |
Health condition(s) or problem(s) studied | Panic disorder |
Intervention | CBT: the CBT protocol is based on the work of Clark and Barlow. Patients in the CBT group received up to 21 CBT sessions each lasting approximately 50 minutes. From session 16 onwards, sessions were scheduled with five-week intermissions. CBT consisted of the following: 1. Interoceptive exposure 2. Cognitive therapy 3. Exposure-in-vivo SSRI group: patients receiving an SSRI visited their therapist 12 times, with weekly sessions during the first month and the remaining sessions distributed evenly over the treatment period of one year. Each visit lasted approximately 20 minutes. SSRIs used: fluvoxamine, sertraline, citalopram, fluoxetine, and cipramil. Tapering started three months before post-test. Combination therapy of CBT and SSRI group: patients received both treatments, delivered in a parallel manner by different therapists. |
