We have a ✨NEW PREPRINT✨! Using data from the @clscohorts.bsky.social Millennium Cohort Study and linked healthcare records, we tested the association between social media use and psychiatric diagnoses in secondary care in young people in England. This is still a work in progress - feedback welcome!

Well, well, well. The “age assurance” part of the UK's Online Safety Act has finally gone into effect, with its age checking requirements kicking in a week and a half ago. And what do you know? It's turned out to be exactly the privacy-invading, freedom-crushing, technically unworkable disaster that everyone with half a brain predicted it would be. Let's start with the most obvious sign that this law is working exactly as poorly as critics warned: …

Wrote about how the UK's online age verification requirements are already proving to be a disaster (as UK regulators were clearly warned it would be) and how unhelpful the UK's response to this mess has been, including their tech minister saying anyone who complains supports predators.

Today I presented my work on data from the @unicefinnocenti.bsky.social Disrupting Harm survey at #IPC2025 in Brisbane! It was a great opportunity to engage with other researchers interested in investigating youth mental health in the population.

Happy to share my new study, publ. in Social Science Research 🎉 Bottom line: Yes, adolescents use their phones a lot 🤳 But I find no support for the notion that this use displaces reading, homework, hobbies, physical act., sleep... Instead: Changing media preferences 📺 ->📱. doi.org/10.1016/j.ss...

Shame on the Guardian for publishing this as if Sullivan is an independent expert. Sullivan is a well-known gender-critical campaigner, & advisor to Sex Matters, a prominent GC campaign group which is reported to be deeply entangled with anti-LGBTQ+ movements: yorkshirebylines.co.uk/news/home-af...

TW: harm to children.

My research into the effects of the UK government puberty-blocker ban has finally been published after peer-review.

It details the severe harm being caused to young trans people & children by the Starmer government's puberty-blocker ban.

Unlike Cass it is peer reviewed...

Harming children: the effects of the UK puberty blocker ban

This paper presents an analysis of data from trans children and young people and their parents following the imposition of a UK-wide ban on puberty blockers for this group. The consequences of this...

is it just me?

The meme in which a man skates down a stair railing on a rake, but ultimately ends up standing on it so it hits him in the face anyway. In the bottom left corner the words "word limit: 3000" appear. Along the man's path down the railing, the words "concise introduction", "briefly lay out limitations" and "additional results in the supplementary" appear. Finally, as he is hit in the face, the caption reads "1700-word methods section.
