In the base case internet-based cognitive behavior therapy (ICBT) is simulated to be the dominant strategy generating 0.260 QALYs and saving €2536 per patient compared to face-to-face CBT, which is confirmed by deterministic and probabilistic sensitivity and scenario analyses.

Within the context of excess demand for psychotherapy, harmful long waiting times and increasing health care costs, ICBT has the potential to decrease time-to-treatment and to free therapists’ capacity in order to treat more and the most severe patients in a face-to-face setting with a higher intensity.
