Therapists
Therapists will be recruited mainly from the outpatient units of the Universities of Dresden and Frankfurt. All therapists must be either licensed psychotherapists or in advanced post-graduate CBT training (at least 1.5 years of training). Study-specific training will focus on how to use the app, how to conduct and analyze behavioral experiments, and how to use techniques of cognitive restructuring. Therapists are required to apply the TG-APP procedures with a pilot patient to gain experience and expertise in this particular form of blended therapy. All treatments will be supervised by psychotherapists with at least five years of clinical experience under their state licensure to ensure adherence to intervention protocols.
