Research Review: Viewing self-harm images on the internet and social media platforms: systematic review of the impact and associated psychological mechanisms.

Viewing self-harm images online may have both harmful and protective effects, but harmful effects predominated in the studies. Clinically, it is important to assess individual's access to images relating to self-harm and suicide, and the associated impacts, alongside pre-existing vulnerabilities and contextual factors. Higher quality longitudinal research with less reliance on retrospective self-report is needed, as well as studies that test potential mechanisms. We have developed a conceptual model of the impact of viewing self-harm images online to inform future research.
