A festive holiday greeting card with a white background framed by green pine branches, pinecones, and red berries. At the top, in large red script, it says “Happy festivities.” Below, in smaller text, the message reads:
“As we reflect on our progress and achievements in 2025, we are truly grateful for the research community that uses and supports the Catalogue of Mental Health Measures and the Atlas of Longitudinal Datasets. Your enthusiasm for what we do means the world to us!
We’re excited for the coming year and remain committed to improving the Catalogue and the Atlas to facilitate longitudinal research in 2026. We wish you a happy and healthy new year!”
At the bottom are three logos: Atlas of Longitudinal Datasets, Catalogue of Mental Health Measures, and PALM (Platforms for Longitudinal Mental Health Data).

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.
