The secondary objective is to a) investigate the cost-effectiveness of this treatment b) to study if any variables could moderate/mediate the treatment outcome, c) and to investigate the importance of sudden gains for the treatment outcome Trial Design: Randomized controlled trial with an active control and a waitlist control, who also will recieve treatment after the first group has finished. Duration: Ten weeks Primary Endpoint: Difference in worry symptoms between the treatment groups at week 10. Long term follow-up is also investigated (baseline to 4-months after treatment completion and baseline to 12-months after treatment completion). Efficacy Parameters: Penn State Worry Questionnaire (PSWQ) Safety Parameters: Adverse Events is assessed via the internet.
