Review: Interventions to prevent or manage self-harm among students in educational settings - a systematic review

At least half of all young people who die by suicide have previously self-harmed and most of those who self-harm will not seek help from health services for self-harming behaviours. By default, schools, colleges and universities necessarily play a key role in identifying those who self-harm and supporting them to access help.

We conducted a systematic review (PROSPERO ID: CRD42021243692) of five databases (Medline, PsycINFO, ASSIA, ERIC and BEI) for quantitative studies evaluating interventions to reduce self-harm among students in schools, colleges and universities.

We identified six eligible studies that reported interventions. Two interventions used mindfulness-based approaches and the remaining four interventions focused on in-classroom education. Three interventions reported a significant reduction in self-harm, all three used in-classroom education. Of the six studies, one study was rated methodologically moderate, while the remaining five were weak.

In summary, the evidence base is limited in size and quality. Most current interventions to address self-harm in schools focus on training staff in awareness, with a significant gap in direct support for students.
