Summary

The purpose of this study is to investigate the differences in treatment outcomes between individually tailored and transdiagnostic internet-based cognitive behavioral therapy (ICBT), as well as the differences between weekly support by a specific therapist and weekly support by a team. The target group is adults (18 years or older) who experience mild to moderate depression symptoms, anxiety, stress or other psychological symptoms. The ICBT, in both types of treatment contents, consists of modules that the participants will work with for eight weeks in total. Participants will be recruited in Sweden with nationwide recruitment.

Detailed description

This study is a factorial randomized controlled trial with the aim to investigate ICBT with two kinds of treatment contents and two kinds of support. Participants will either be randomized to an individually tailored treatment, where they will be selecting their own modules that they wish to work with, or be randomized to a transdiagnostic treatment, that consists of Unified Protocol that is developed by David Barlow and colleagues. Participants will also be randomized to either get weekly support by one specific therapist or get support by "a team", meaning that the participant will get support from different therapists each week. In both kinds of support, the participant will have the opportunity to ask for support during the other times of the week as well. Primary outcome measures are depression symptoms (measured with Beck Depression Inventory-II) and anxiety symptoms (measured with Beck Anxiety Inventory). Other, secondary, outcome measures used will for example be about stress symptoms, insomnia symptoms, and quality of life. Pre-treatment measurement, post-treatment measurement and one-year follow up is planned to be collected through an online survey.
