Internet-based Cognitive Behavioral Intervention for Adolescents With Anxiety Disorders

The goal of the randomized controlled trial is to find out if the internet-based therapy (iCBT) intervention CoolMinds, is effective in helping adolescents with anxiety. The adolescents in the study are aged between 12 and 17 years of age, who live in the region of Southern Denmark. They must have an anxiety diagnosis according to the Diagnostic and Statistical Manual-5 (DSM-5) criteria. The main questions it aims to answer are: 1. If getting anxiety treatment with CoolMinds will lead to a greater reduction in anxiety symptoms, compared to a waitlist. 2. What effect different degrees of therapist support have on the treatment. Participants will be getting 14 weeks of the iCBT intervention CoolMinds, and they will be asked to answer questionnaires about their mental health before and after the treatment. Researchers will compare three different groups, with 56 adolescents in each group. The first group will receive iCBT with weekly scheduled feedback. The second group will get iCBT with feedback whenever the adolescents ask for it. The last group will be on a waiting list for 14 weeks, before receiving treatment.
