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.

Detailed Description

Within the context of a research and teaching clinic at the Department of Psychology and Behavioral Sciences, Aarhus University, Denmark, 70 adolescents aged 13-17 with a primary anxiety disorder as assessed by the ADIS C/P will be randomly allocated to either a 3 month wait-list control condition or a treatment condition.

The treatment consists of an internet-based self-help program for adolescents with anxiety disorders called 'Chilled Out', based on material from the well-established manualised group-treatment Cool Kids Program: Adolescent version. It consists of 8 CBT-inspired modules of approximately 30 minutes each distributed over a 14-week period. The program is interactive using a combination of different media (text, audio, illustrations, cartoons, and videos) to deliver psychoeducation and CBT-inspired techniques, activities and exercises for adolescents to manage their anxiety. In addition, the adolescent will receive a limited amount of therapist support calls.

Participants (youth and parents) are assessed with semi-structured diagnostic interviews and self-report measures before treatment, after 14 weeks (post treatment) and 3 months after treatment (follow-up).

Participants are assessed at pre, post and 3-month follow up.
