The work has been commissioned by the UK government’s Department for Science, Innovation and Technology (DSIT) after a review by the UK Chief Medical Officer in 2019 found the evidence base around the links to children’s mental health were insufficient to provide strong conclusions suitable to inform policy.
The project – led by a team at the University of Cambridge, in collaboration with researchers at several leading UK universities including Bristol – is aimed at improving policymakers’ understanding of the relationship between children’s wellbeing and smartphone use, including social media and messaging. It will help direct future government action in this area.
Project lead Dr Amy Orben from the Medical Research Council Cognition and Brain Sciences Unit (MRC CBU) at the University of Cambridge said: “There is huge concern about the impact of smartphone use on children's health, but the evidence base remains fairly limited. While the government is under substantial time pressure to make decisions, these will undoubtedly be better if based on improved evidence.
“This is a complex and rapidly evolving issue, with both potential harms and benefits associated with smartphone use. Technology is changing by the day, and scientific evidence creation needs to evolve and innovate to keep up.
“Our focus will be on deepening our causal understanding of the effects of new technologies, particularly over short timescales, to ensure that decisions are informed, timely and evidence-based.”
