What this trial studies

This is a randomized waitlist-controlled trial testing the Groups 4 Health (G4H) brief group intervention for loneliness among University of Helsinki students. Participants are randomized to start G4H immediately or after a 19-week waitlist and the intervention consists of five facilitated group sessions delivered over seven weeks with follow-up assessments. The trial collects psychosocial measures, facilitator characteristics, and biological measures before, during, and after the intervention, including cortisol, heart rate variability, alpha-amylase, DNA methylation, and genotyping. Cost-effectiveness of the intervention is also measured to inform practical implementation.
