The WHOQOL-BREF (Skevington et al., 2004, https://doi.org/10.1023/B:QURE.0000018486.91360.00) is a validated and established questionnaire for assessing quality of life. The Rosenberg Scale (Rosenberg, 1965; https://doi.org/10.1037/t01038-000) is a self-report questionnaire that measures self-esteem. In addition, questions are asked about the subjective acceptance of online interventions and feedback on the sessions. The questionnaires of the secondary endpoint will also be administered at the pre- and post-surveys.	—
