Study: Screen time has little effect on teenagers' well-being

The research, based on analysis of the screen use of more than 17,000 teenagers across Ireland, the US and the UK, found use of screens before bedtime was completely unrelated to psychological wellbeing, and screen time more generally had a “minuscule” effect on wellbeing in teenagers when compared with other activities in an adolescent’s life.

The effect was believed to be small enough that adolescents “would need to report 63 hours and 31 minutes’ more of technology use a day in their time-use diaries to decrease their wellbeing” by an amount big enough for them to notice.
