Ms Chloe Setter:

Absolutely. There is currently no collective agreement among experts on the amount of time that is good but we have been working with external experts on this. We have worked with the Boston children's wellness lab to develop a screen time limit and all under 18s on TikTok have a 60-minute default screen time limit. Once they reach the 60 minutes, they have to input a passcode if they want to keep watching. The reason we do that is based, as I said, on working in consultation with experts on how young people approach these kind of things and being intentional about the amount of time they spend. Giving them those nudges, those pieces of information such as that they have spent 60 minutes, helps them develop critical thinking and gives them a reminder. We also surface other take-a-break reminders. We do not send push notifications, for example, to ages 13 to 17 after 9 p.m. and to those 16- to 17-year-olds after 10 p.m.

I refer to research we have done, for example, with Internet Matters, an NGO. We did work with teens and parents in Ireland, the UK, France, Italy and Germany. We asked young people and parents about what worked for them in this sort of scenario and they told us they wanted more data about their usage. We introduced a dashboard which gives them a weekly notification or recap of how much time they have spent and what time of day they were spending time, and gave them screen time breaks, which we have done with the screen time limit.

A key thing to mention here is perhaps family pairing. We have some excellent family pairing tools that allow parents and guardians to customise their teens' experience. They can set the screen time limit.

You can set the time of day. It can be weekends only or school holidays only. It is a very customisable experience. In that scenario, the young person would need to get the passcode from their parents. They cannot simply override it. There are things parents can do to help, such as to have those conversations about what a healthy amount of time is. That might vary depending on the child, the time of day or what sort of day it is, a weekday or so on.
