Participants randomized to RNT-ACT will receive a total of 2 sessions of 60 minutes each as well as audio files to listen to between the occasions administered via internet. Previous studies have indicated that it doesn't make much of a difference whether the temporal distance between session 1 and session 2 is between 1 week and up to 3 months. At occasion 1, the time for occasion 2 is set. The temporal distance in days will noted for each patient.
