Clinical Trial Summary

The goal of this clinical is to pilot test an internet delivered cognitive behavior therapy (ICBT) based on intolerance of uncertainty (one of several existing specific cognitive models for how worry works) in treating generalised anxiety disorder (GAD). The main aims is to: - Test the preliminary effect of the intervention in lowering symptoms of GAD as measured by the self report scale GAD-7 - Test procedures for recruitment, assessment, treatment and follow up - Test the acceptability of the intervention as measured by the Client Satisfaction questionnaire-8, dropout and adverse events Participants will apply for treatment in an online system, be assessed via video by a licensed clinical psychologist and then receive a 10 week long ICBT intervention based on the intolerance of uncertainty model. This is a pilot study for an upcoming randomized controlled trial.
