Translation and Development of an Online Self-help Intervention With Subsequent Feasibility Study

The purpose of this study is to determine the feasibility and effectiveness of an internet-based self help program concerning satisfaction with the treatment and their life, depression and anxiety. Both study groups get access to the internet-based self-help program. The intervention group receives additional feedback to their progress in the program from an online therapist. The investigators hypothesize that (1) at least 75% of the patients in the intervention group are \"satisfied\" or \"very satisfied\" with the self-help program, (2) 50% of the patients in the intervention group work with all eight units and (3) patients of the intervention group have a higher emotional competence than the patients of the control group at the end of the self-help program.
