“…Considering a possibly strong association between sick leave and health care utilization and resulting costs, the equivalent trend in direct costs and sick leave is not surprising and further supports a similarity in treatment effects for both BT and PDT. These results are also in accordance with cost-effectiveness analyses of short-term outpatient psychotherapies and health economic studies on mental disorders (Bode, Götz von Olenhusen, Wunsch, Kliem, & Kröger, 2017;Bothe, Jacob, Kröger, & Walker, 2020;Mukuria et al, 2013;Radhakrishnan et al, 2013;Yonatan-Leus, Strauss, & Cooper-Kazaz, 2021).
