-------------------------------------------------TITLE: Getting a smartphone before age 13 linked to worse mental health in young adulthood
New research provides evidence that receiving a smartphone early in childhood is associated with poorer psychological well-being in young adulthood. The findings indicate that these negative outcomes are largely tied to early access to social media, which opens the door to cyberbullying, poor family relationships, and disrupted sleep. The study was published in Journal of Human Development and Capabilities.
Scientists and policymakers have expressed growing concern over the modern digital landscape. Smartphones operate as gateways into algorithmically curated digital environments. These algorithms are designed by artificial intelligence (AI) programs to maximize user engagement, often by presenting content that keeps users scrolling.
When young children navigate these spaces, they face unique challenges. According to a 2026 review, adolescent brains undergo biological changes that heighten their sensitivity to social feedback and variable rewards, like notifications and likes. This makes young minds particularly vulnerable to the design features of modern digital platforms.
Efforts to manage this issue have been mixed. For example, a study covered by PsyPost in 2026 evaluated the concurrent impact of restricting phone use during secondary school hours and noted little to no mental health improvement from daytime bans alone. With inconsistent findings across the scientific literature, questions remain regarding the long-term impact of digital exposure starting in early childhood.
The authors of the new study focused on the concept of mind health, which they distinguish from traditional clinical categories like depression and anxiety. Mind health encompasses the full complement of emotional, social, and cognitive capacities that allow a person to navigate life’s challenges and function productively.
The research, led by Tara C. Thiagarajan, founder and chief scientist of Sapien Labs, aimed to determine the population-level developmental consequences of owning a smartphone during childhood. They sought to understand how the age at which a child receives their first smartphone correlates with their mind health as a young adult.
“We are a nonprofit tracking mind health across the globe and exploring how different aspects of the environment contribute to the decline across each younger generation,” Thiagarajan told PsyPost. “One of the most significant environmental shifts that tracks with this trajectory is the advent of smartphones. We wanted to understand the cumulative effect of having a smartphone in childhood on development rather than just the immediate effect of using it.”
To explore this, the researchers analyzed data from the Global Mind Project, a large-scale data acquisition initiative. Their sample included over 100,000 young adults between the ages of 18 and 24, spanning 163 countries and various cultural backgrounds. Participants completed an online assessment tool called the Mind Health Quotient.
The Mind Health Quotient captures 47 different functions and symptoms, generating a score that reflects a person’s overall mental well-being on a spectrum from distressed to thriving. The survey also collected contextual information, including the age at which each participant received their first smartphone and when they first created social media accounts. The researchers used regression analysis to identify associations between early phone ownership, potential mediating factors, and current mind health.
The results showed a consistent pattern across different regions and languages. Receiving a smartphone before the age of 13 was associated with progressively lower mind health scores in early adulthood. For example, the average Mind Health Quotient score was 30 for individuals who acquired their first smartphone at age 13, but it dropped to just 1 for those who received one at age five.
“That the younger a child got a phone, the worse their mental health is likely to be in adulthood,” Thiagarajan explained. “This relationship is particularly steep before age 13. That means that every successive year before 13 makes it even worse.”
The percentage of young adults considered distressed or struggling was higher among those who acquired smartphones earlier. Compared to those who received a phone later in adolescence, females who obtained a smartphone at a very young age experienced a 9.5 percent higher rate of severe struggles, while males showed a 7.0 percent higher rate.
Specific symptoms also varied based on the age of first smartphone ownership. Among female participants who received a smartphone at age five or six, 48 percent reported severe suicidal thoughts as young adults, compared to 28 percent of those who received their first phone at age 13. Among males, the figures were 31 percent for early adopters and 20 percent for those who waited until age 13. Participants who owned phones earlier also reported higher rates of aggression, feelings of detachment from reality, and diminished emotional resilience.
“We were surprised that the specific aspects that early smartphone exposure effects after controlling for other factors are things like suicidal thoughts, aggression towards others and detachment from reality and not the typically discussed anxiety and depression,” the researcher noted.
To understand why this association exists, the researchers looked at several potential contributing factors. Globally, the age at which participants first accessed social media accounted for about 40 percent of the link between early smartphone ownership and poorer adult mind health.
Other factors played a role, but they were often tied to social media use. Cyberbullying and poor family relationships were linked to early smartphone ownership, and the researchers found that these issues were largely downstream effects of accessing social media at a young age. On the other hand, early smartphone use was also associated with disrupted sleep, but this sleep disruption appeared to happen independently of social media access, suggesting it might stem from other screen activities like gaming or watching videos.
The study highlighted regional differences, particularly in developed, English-speaking countries. Young adults in these countries reported receiving smartphones at an average age of 11, compared to ages 14 to 16 in parts of Africa, South Asia, and the Middle East.
In these English-speaking nations, the age of social media access explained up to 70 percent of the negative mind health associations linked to early smartphone ownership. In this region, experiences of cyberbullying and poor family relationships were almost entirely downstream of early social media access. For females in these countries, early social media access was also linked to an increased likelihood of experiencing sexual abuse, which in turn predicted poorer mental health outcomes.
The findings are in line with research covered by PsyPost in 2026, which found that youth social media engagement is consistently linked to poorer emotional well-being and diminished self-worth. It is worth noting, however, that the earlier study examined ongoing digital usage during childhood rather than the specific age of first smartphone ownership on young adult outcomes.
The findings are in tension with an earlier study regarding whether adolescent phone use impairs long-term psychological development. That previous study specifically tracked self-control over time in teenagers in South Korea, whereas the new study relied on retrospective reports of first smartphone ownership and broader adult mental health outcomes.
As with all research, there are a few things to keep in mind. The study relies on observational data, meaning it can show links between early phone ownership and later mental health, but it cannot establish that one directly causes the other. Participants were also asked to recall events from their childhood, which can introduce memory errors.
“These results reflect the population level effects,” Thiagarajan said. “What that means is that they reflect having phones in a world where almost everyone else has one too. If you are the only one without a phone, it doesn’t mean you will easily have better outcomes. In fact it could even be more isolating.”
“On the other hand if an entire group doesn’t have phones it will change the social dynamic and behaviors in positive ways,” she added. “So the more impactful solutions are likely to be population level bans until 13 at the school or societal level.”
The researchers did not measure the total amount of time participants spent on screens during childhood. The study also lacked data on the specific types of online content the individuals interacted with as they grew up. The findings reflect broad patterns across large populations and do not predict the exact outcome for every child who receives a smartphone at a young age.
“We are working on understanding if these cumulative effects can be reversed and how,” Thiagarajan said. “One example is this recently published camp study.”
The study, “Protecting the Developing Mind in a Digital Age: A Global Policy Imperative,” was authored by Tara C. Thiagarajan, Jennifer Jane Newson, and Shailender Swaminathan.
