Primary outcome parameters
The primary outcome parameters are therapy effects on MPA measured by the Bühnenangstfragebogen (BAF) as well as changes in cardiac reactivity using HRV. Therapy response criteria for MPA are defined by a decrease of at least 50% of the BAF total score compared to T0. Remission ist defined by no psychological distress or impaired functioning due to the symptoms. Regarding the cardiac reactivity, HRV is not yet sufficiently established as a biomarker for music performance and there is no reliably data in this area so far which is why we evaluate this data exploratively. However, in case of a successful reduction of MPA we expect a significant higher HRV during the BAT after therapy compared to before therapy.
