- Public TitleA randomized, prospective, multicenter study of the effective treatments of panic disorder: cognitive behavioral versus antidepressants versus a combination therapy.
- Scientific TitleShort- and long-term effectiveness of three treatments for panic disorder: CBT, SSRI, or CBT+SSRI.
- hypothesisOn short-term, the Combined treatment is expected to be superior to either mono-treatment. On long-term it is expected that CBT will prove to be more durable and that patients in the SSRI will require more mental health care during the one-year follow-up period.

- InterventionsCBT: 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 5 week intermissions. CBT consisted of the following: 1. interoceptive exposure, 2. cognitive therapy, and 3. exposure-in-vivo.

SSRI: 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: fluvoxamine, sertraline, citalopram, fluoxetine, and cipramil. Tapering started three months before posttest.

CBT+SSRI: Patients received both treatments which were delivered parallel by different therapists.

- Brief summaryPD tends to be a chronic condition associated with substantial reduction in quality of life. Relapse rates are high. For these reasons, attempts to study (long-term) effectiveness of the different treatments for PD, seems in order. In today’s clinical practice, PD is mostly treated with some form of either a psychopharmacological (mostly SSRI) treatment or a psychological (mostly CBT)treatment. Besides offering some mono-treatment, a combined treatment seems to be offered regularly as well. Evidence for a short-term benefit of a combined treatment is still scarce however. Further, there are potential long-term disadvantages to a combined treatment. In the present study, one hundred and fifty patients were randomised to receive either CBT, SSRI, or CBT+SSRI. All treatments lasted one year. After nine months, the SSRIs were gradually tapered-off and patients were thus medication-free at post-test. During the second (follow-up) year, participants came to the clinic twice to be interviewed and to fill-in questionnaires. The aim of the present research is twofold. First, we want to study the short- and long-term effectiveness of the different treatment modalities. Second, we want to gain insight into the costs of these treatments and also of the additional treatments that may be warranted during the follow-up period. Results of this study may lead to a future situation in which patients with this disabling disorder will, when they seek help for the first time, be offered the most effective treatment with the most powerfull long-lasting effect.
