NCT02535403

Brief Summary

Cognitive behavioral therapy (CBT) is a well-documented and effective method for the treatment of children and adolescents with anxiety disorders. Lately there has been an increase in the development and use of internet-based CBT programs (ICBT), as a means to reduce costs and enhance accessibility of psychological interventions. ICBT has proven efficacious towards adults with anxiety disorders. Research in the field of ICBT with children and adolescents is still in its infancy though and to date, no program targeting anxiety disorders has been developed nor evaluated in Denmark. The primary objective of this study is to investigate the efficacy of a newly developed internet-based treatment program for adolescents with anxiety disorders. The effect will be examined in a randomized controlled trial comparing ICBT to a wait-list control condition.
