Brief Summary

In this study, people who suffer from loneliness will be randomized to three study conditions. The first and second group get an account to an internet-based self-help intervention. The first group also receives weekly feedback from a coach and the second group receives an automated email on a weekly basis. The third group is a waiting control group. In all three conditions additional care or treatment is allowed. The aim of the study is to investigate the efficacy of an internet-based self-help intervention to reduce feelings of loneliness compared to a waiting list and the effect of support during the intervention. Assessments are at baseline, 5-week, 10-week, 6-months and 12-months post-randomization. Participants in the waiting control group get also access to the intervention and fill out questionnaires at baseline, 5-week and 10-week post-randomization and get also access to the intervention 10 weeks after randomization.
