Background: Mindfulness-based programming comprising both formal (FM) and informal (IM) mindfulness practice is increasingly offered to university students. However, difficulties with emotion regulation, self-criticism, and a potentially complex relationship with their body may undermine the benefits of FM for students with a history of nonsuicidal self-injury (NSSI), given its requirement of sustained attention on thoughts, emotions, and bodily sensations. IM may be better tolerated by these students. This protocol describes a randomized controlled trial comparing a brief FM practice, a brief IM practice, and an active control task in university students with and without recent NSSI.
Methods: Recruitment began in November 2022. An online, parallel-group, single-blind, randomized controlled trial will compare a 10-min, single-session FM practice, a 10-min, single session IM practice, and a 10-min, single session active control task in university students with and without recent NSSI. Outcomes will be assessed immediately pre-intervention and within five minutes post-intervention. The primary outcome will be state mindfulness. Secondary outcomes will be state stress, state well-being, and acceptability. Students with a history of NSSI are expected to report (i) greater improvements in state mindfulness, stress, and well-being, and (ii) greater acceptability in the IM condition, relative to the FM and control conditions. This distinction is not expected to occur in the no-NSSI comparison group.
Conclusion: This trial is the first to parse out the impacts of FM versus IM practice among university students with and without a history of self-injury. Findings will be relevant to academic and clinical audiences within university settings.
