Abstract [en]

Numerous controlled trials have been published on the effects of internet-delivered psychological treatments for a range of problems and disorders. Generally, trials adhere to the CONSORT statement and include control groups. Often this is attention control, waitlist but also alternative treatments. In experimental psychology factorial designs is the common way to investigate research questions but in psychotherapy research this is rare given the need for large samples in order to have sufficient power to detect differntial effects of  independent variables (like for example different versions of a treatment). With the advent of internet-delivered CBT (ICBT) this has changes and it is now possible to run trials with larger samples. At the same time there is really no need for more studies showing that a treatment is better than just waiting (for some areas at least like depression). In this talk we will present result from three completed factorial design trials in which we have manipulated support form (on demand versus scheduled in one trial and chat-support versus just email in another), and also other aspects like learning support and choice of treatment. The talk will end with a discussion on future directions of ICBT research with regards to design of trials.
