Parents who club together to postpone giving their children smartphones until the age of 14 appear to improve the mental wellbeing of the whole group, according to a fresh working paper released on Friday 04 September 2026. The research, led by economist Gregory Veramendi, analysed data from over 12,000 UK state primary schools and found a noticeable drop in recorded social, emotional and mental health needs where the “parent pact” was widely adopted.
Examining the Evidence
The study compared schools where more than 20 % of parents had signed the Smartphone Free Childhood pledge with those where fewer than 5 % had done so. In the high‑uptake schools, the proportion of pupils logged with SEMH (social, emotional and mental health) needs was roughly eight per cent lower than in the low‑uptake schools. Veramendi wrote in the paper: “My main finding is that children’s recorded mental‑health needs fall substantially where the pact is widely adopted.” He stressed that the work is still awaiting peer review and has been published by the Institute for Fiscal Studies.
What the Numbers Show
Beyond the headline figure, the research highlights that the benefit stems from shifting the norm around when a child first receives a phone, rather than from school‑day bans alone. Veramendi pointed out that while schools are now legally required to restrict smartphones during lessons, such measures alone did not produce a clear mental‑health advantage. By contrast, a community‑wide delay in ownership costs almost nothing to implement and appears to move the needle on wellbeing across the entire pupil cohort.
Expert Reaction and Caveats
Not everyone is convinced the findings prove causation. Cadice Odgers, professor of psychology and informatics at the University of California, Irvine, warned against over‑interpreting the results. She said: “I would not place this in the ‘causal’ evidence category … it does not actually measure whether the students had lower smartphone use or exposure, the measure is parents’ intent to give the child a phone as indicated by signing a pledge. It is a bold jump here to making this claim. Where is the evidence that signing this pledge led to reduced smartphone ownership, use and delay?” Previous work from King’s College London has shown that one in four children and young people display a problematic relationship with smartphones akin to behavioural addiction, underscoring why the debate matters.
Why it Matters
If the pact’s effects hold up under further scrutiny, it could offer a low‑cost, grassroots complement to existing phone‑ban policies in schools and potential statutory age limits. For parents, educators and policymakers wrestling with rising concerns over screen time and youth mental health, the study provides a concrete talking point: collective action, rather than individual restriction, might be the key to fostering healthier digital habits from an early age.
