The Effects of Mindhelper.dk: a Self-guided Digital Mental Health Promotion Service Targeting Young People

In a two-armed randomized controlled trial 15-25-year-olds will be recruited via social media to evaluate the effectiveness of Mindhelper.dk; a Danish self-guided, digital, mental health service offering information, self-help tools, and guidance to young people. Participants will be randomly allocated to an intervention group (receiving information about Mindhelper.dk) or a control group (no information about Mindhelper.dk). Outcomes, including well-being (WHO5), psychological functioning (SWEMWBS), help-seeking intentions, and body appreciation (2-item BAS-2SF), will be measured at 2-, 6-, and 12-weeks post-randomization and analyzed using the intention-to-treat approach. Qualitative interviews with intervention group participants will provide complementary insights, and a cost-effectiveness analysis will also be conducted.

A study protocol will be made publicly accessible upon acceptance for publication in a suitable journal
