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.
