Plain English Summary
Background and study aims:
Panic disorder is a severe mental disease where patients experience (unexpected) frightful panic attacks. Most patients try to avoid these attacks by developing avoidance behaviour, e.g. they avoid crowded places. Panic disorder is also a burden for society as medical and social costs are high. Panic disorder treatment guidelines suggest cognitive behaviour therapy (CBT) or treatment with drugs, although CBT has known, longer lasting effects. Normally, CBT takes 10-12 weekly sessions, but CBT is not always easy available and waiting lists are long. Therefore, shorter and cheaper programs, such as guided self-help or internet based treatments have been tested and been successful in the treatment of panic disorder.
This study's goal is to examine whether a short program of guided self-help for panic disorder is beneficial, and only followed by more intensive treatment when necessary
Who can participate?
Patients with a panic disorder with or without agoraphobia. Either men or women, aged between 18-70 years.
What does the study involve?
130 patients (across different treatment centres) will be randomly allocated to one of two treatment conditions:
1. A brief CBT intervention (guided self-help) of 10 weeks followed by CBT (13 sessions) only when necessary
2. Treatment as usual according to the (NICE) guidelines
What are the possible benefits and risks of participating?
There are no negative risks known, since both treatment conditions are well studied and proven to be effective in the treatment for panic disorder. Benefits from enrolling in the study are the monitoring of symptoms and the adjustment of the therapy when necessary. A possible disadvantage is the extra time it may cost to fill in the extra questionnaires.

Acronym
Study hypothesis
1. Guided self help is an effective first step in the treatment of panic disorder, compared with treatment as usual.
2. In the second step of the stepped care intervention, manualised CBT, panic disorder symptoms will be faster in remission as compared to the treatment as usual.
3. Symptom severity, duration of panic disorder, comorbidity on axis I and II will not predict treatment results of guided self help.
