- InterventionsThe internet course (FobieŽn onder controle) is based on exposure therapy. This intervention is based on a published self-help book (written by drs. Manja de Neef and prof. Cuijpers), which was used in a series of television programme on self-help for phobias (by broadcasting company Teleac/Not). This treatment is based on exposure therapy in which the patients gradually exposes himself or herself to the feared situation.
The intervention consists of five weekly parts, and includes reading materials and homework assignments for every week. The internet-based intervention is already available and is tested in a pilot project. During the therapy the patient has about five contact moments with the coach (total time per client 50 to 75 minutes). The coaching is aimed at supporting the patients to work through the intervention and assignments, not to develop a therapeutic relationship. The coaching is given by Mthese students from our faculty, who will receive a training from the developers of the intervention. Integrity of the intervention is checked by an independent psychotherapist.

The control group will receive care as usual.

- Brief summaryAlthough several meta-analyses have shown that internet-based guided self-help is effective in the treatment of anxiety disorders, the cost-effectiveness in mental health care settings has not been studied well. We will conduct a randomized non-inferiority study in which we examine the relative cost-effectiveness of internet-based guided self-help as compared to usual care.
We will test the hypothesis that guided self-help is not less effective than care-as-usual. Based on international studies we expect this intervention to be effective. Care as usual is mostly pharmacotherapy or psychological treatment. A total of 320 clients suffering of a phobia from 4 institutes of mental health care institutions will be randomized to care-as-usual or guided self-help.
The intervention is an internet-based guided self-help course (FobieŽn onder controle) which is based on exposure. The control group receives a selfhelpbook. The primary outcome measure is level of phobic symptoms , anxiety and depression. Secondary outcomes will be panic-symptoms, satisfaction with the intervention and the use of alcohol and or drugs.
