Honestly the way you keep trying to tie this all back to screen time is worrying, it feels like you’re taking the preconceived conclusion that screen time is a huge part of this and trying to make it fit the data, when it’s just as likely it’s quite a small component of the issue compared to much larger societal and economical reasons young people are in these situations.

I think you want it to be screen time because seeing people with high screen time affects you emotionally, and you subconsciously want it to be something that simple - and potentially something that can be changed through choice so some blame can be placed on the victims. Such a thing is attractive to a certain type of mind. That’s why I said you were holding a hammer looking for nails, you’re holding a screen time hammer and that’s not the way you should approach this if you want the scientific truth.

Good luck out there.
