An international team of experts believes that girls and boys are more sensitive to the detrimental consequences of social media use at various stages of adolescence.
According to the study, when girls are 11-13 years old and males are 14-15 years old, there is a negative relationship between social media use and life happiness. At the age of 19, more social media use predicts worse life satisfaction. At times, the connection was not statistically significant.
According to a study published today in Nature Communications, females experience a negative association between social media usage and life satisfaction when they are 11-13 years old and boys when they are 14-15 years old. Increased social media usage predicts decreased life satisfaction at 19 years of age. At times, the connection was not statistically significant.
Social media has significantly transformed how we spend our time, share information about ourselves, and communicate with others in little over a decade. This has sparked significant worry about its possible detrimental influence, both on individuals and on society as a whole. Even after years of research, there is still a lot of doubt regarding how social media use affects happiness.
A team of scientists including psychologists, neuroscientists and modellers analysed two UK datasets comprising some 84,000 individuals between the ages of 10 and 80 years old. These included longitudinal data — that is, data that tracks individuals over a period of time — on 17,400 young people aged 10-21 years old. The researchers are from the University of Cambridge, University of Oxford, and the Donders Institute for Brain, Cognition and Behaviour.
The team looked for a connection between estimated social media use and reported life satisfaction and found key perio of adolescence where social media use was associated with a decrease in life satisfaction 12 months later. In the opposite direction, the researchers also found that teens who have lower than average life satisfaction use more social media one year later.
Adolescent and Social Media
In girls, social media use between the ages of 11 and 13 years was associated with a decrease in life satisfaction one year later, whereas in boys this occurred between the ages of 14 and 15 years. The differences suggest that sensitivity to social media use might be linked to developmental changes, possibly changes in the structure of the brain, or to puberty, which occurs later in boys than in girls. This requires further research.
In both females and males, social media use at the age of 19 years was again associated with a decrease in life satisfaction a year later. At this age, say the researchers, it is possible that social changes — such as leaving home or starting work — may make us particularly vulnerable. Again, this requires further research.
At other times, the link between social media use and life satisfaction one year later was not statistically significant. Decreases in life satisfaction also predicted increases in social media use one year later; however this does not change across age and or differ between the sexes.
Dr Amy Orben a group leader at the MRC Cognition and Brain Sciences Unit, University of Cambridge, who led the study, said: “The link between social media use and mental wellbeing is clearly very complex. Changes within our bodies, such as brain development and puberty, and in our social circumstances appear to make us vulnerable at particular times of our lives.”
Professor Sarah-Jayne Blakemore, Professor of Psychology and Cognitive Neuroscience at Cambridge and a co-author of the study, said: “It’s not possible to pinpoint the precise processes that underlie this vulnerability. Adolescence is a time of cognitive, biological and social change, all of which are intertwined, making it difficult to disentangle one factor from another. For example, it is not yet clear what might be due to developmental changes in hormones or the brain and what might be down to how an individual interacts with their peers.”
Dr Orben added: “With our findings, rather than debating whether or not the link exists, we can now focus on the periods of our adolescence where we now know we might be most at risk and use this as a springboard to explore some of the really interesting questions.”
Further complicating the relationship is the fact — previously reported and confirmed by today’s findings — that not only can social media use negatively impact wellbeing, but that the reverse is also true and lower life satisfaction can drive increased social media use.

The researchers are keen to point out that, while their findings show at a population level that there is a link between social media use and poorer wellbeing, it is not yet possible to predict which individuals are most at risk.
Professor Rogier Kievit, Professor of Developmental Neuroscience at the Donders Institute for Brain, Cognition, and Behaviour, said: “Our statistical modelling examines averages. This means not every young person is going to experience a negative impact on their wellbeing from social media use. For some, it will often have a positive impact. Some might use social media to connect with friends, or cope with a certain problem or because they don’t have anyone to talk to about a particular problem or how they feel — for these individuals, social media can provide valuable support.”

Professor Andrew Przybylski, Director of Research at the Oxford Internet Institute at the University of Oxford said: “To pinpoint which individuals might be influenced by social media, more research is needed that combines objective behavioural data with biological and cognitive measurements of development. We therefore call on social media companies and other online platforms to do more to share their data with independent scientists, and, if they are unwilling, for governments to show they are serious about tackling online harms by introducing legislation to compel these companies to be more open.”
