Rates of most distress measures peaked during the COVID years (2020-21). The proportion of teens repetitively self-harming did not return to pre-COVID levels, unlike other measures of distress.

A group of young people with lived experience of mental health challenges helped to interpret these results and unpick some possible reasons for them

Two groups showed particularly high levels of psychological distress: (1) those identifying as transgender/gender-diverse & (2) those in Youthreach or Further Education and Training centres ("early school leavers")

Our new study on the prevalence of psychological distress among adolescents in Ireland is out.

We looked at anonymous surveys from over 20,000 adolescents across Ireland and explored at how rates of poor mental health, repetitive self-harm and suicide attempt were changing. Read more below! ⤵️

A special thank you to all E-Risk participants and the @eriskstudy.bsky.social team for making this research possible.

Implications:
➡️ When a young person reports being bullied online, it’s important to look beyond the screen.
➡️To impact young people's mental health, we need to consider offline and online challenges + provide early support for anxiety + shape policies around social media use.

We found:
2️⃣ Cybervictimisation was linked to a range of #mentalhealth conditions, but anxiety disorder was the only one independently associated after accounting for family background and offline forms of victimisation.

🗺️ Cybervictimisation is a major public health issue worldwide. What if, beyond the screen, other challenges in their lives might also contribute to this risk?
We found:
1️⃣ 1 in 5 young people experienced cybervictimisation during adolescence, and many had also faced other types of victimisation.

💻 Does Cybervictimisation contribute to poor mental health in young people?
In our new paper in the @lancetchildadol.bsky.social, led by Dr Frédéric Thériault-Couture, we found that 1 in 5 young people were cybervictimised during adolescence, and it contributed to anxiety.
