IMI
This randomized controlled trial indicates that the internet- and mobile-based intervention (IMI) StudiCare Mindfulness constitutes a low-threshold, effective, and safe way to support college students in enhancing their psychological well-being. This holds true for both an unguided version of the intervention and a version with human “guidance on demand” (GoD). However, our results also suggest that GoD might not be a cost-efficient way to enhance the effectiveness of and adherence to mindfulness-based IMIs in the target group of college students, compared with an unguided version of the same intervention. Future trials could investigate the effects of using additional technical means, such as persuasive design, to further optimize adherence.
