Implication

Longitudinal study finds victimisation linked to self-harm in young adults, suggesting prevention is crucial.

Key Points

The study aims to explore the relationship between perceived victimisation and self-harm in young adults, while also considering genetic risk factors.
Used data from the Quebec Longitudinal Study of Child Development (1998-2023).
Analyzed victimisation experiences and self-harm reports from participants aged 20-25.
Calculated polygenic scores (PGSs) for depression, ADHD, and suicide attempts based on genetic data.
17.2% of participants reported self-harm at ages 20-25.
Increased victimisation was significantly associated with higher rates of self-harm.
Polygenic scores for depression and suicide attempts were linked to self-harm but did not change the effect of victimisation.
