Supplementary file 1_How have contemporary studies evaluating self-help digital mental health interventions for young people monitored and reported on adverse events and harms?: a systematic scoping review.docx

These are most scalable when offered as self-help. However, all mental health interventions have the potential to cause harm, and this should be monitored.</p>Aim<p>To identify current practices and gaps in safety reporting, we systematically mapped how adverse events have been monitored and reported in contemporary studies evaluating self-guided DMHIs for young people.</p>Method<p>We conducted a systematic scoping review.

Two databases were searched for relevant studies published between 2019 and 2024. We synthesised the findings narratively, drawing on content analysis to identify patterns.</p>Results<p>We included 37 studies, 12 (32.4%) of which described how they assessed adverse events (AEs). AEs were identified through worsening on wellbeing/psychometric measures, measures of risk and suicidal ideation/behaviour, participants self-identifying AEs, and parental reporting of AEs.
