Overview
Brief Summary
The study is a factorial randomized controlled trial investigating the efficacy of difference versions of internet-administered cognitive behavioral therapy.
Detailed Description
The study is a 2 x 2 design. The first factor thought to be of relevance for the efficacy is the whether the content is selected by the participants themselves or by a therapist. The second factor consists of two levels: regular, continuous weekly support from a therapist or guidance on demand by a health care team consisting of a physician, a nurse, a clinical psychologist, an IT-technician and the principal investigator of the study.
