Negative Effects of Social Media on Girls and Boys
Girls and boys might be more vulnerable to the negative effects of social media use at different times during their adolescence, according to a study in Nature Communications. Girls were found to experience a negative link between social media use and life satisfaction when they are 11–13 years old and boys when they are 14–15 years old. Increased social media use again predicts lower life satisfaction at age 19 years. At other times the link was not statistically significant.
Since its rapid emergence over a decade ago, social media has prompted concern over its possible impacts on wellbeing, especially in younger people.
A team of researchers analysed two UK datasets which included longitudinal data on 17 400 young people aged 10–21 years old. The team looked for a connection between estimated social media use and reported life satisfaction and found key periods of adolescence where social media use was associated with a decrease in life satisfaction 12 months later. Working backwards, the researchers also found that teens who have lower than average life satisfaction use more social media one year later.
In girls, social media use between ages 11 and 13 was associated with a drop in life satisfaction one year later, whereas in boys this occurred between 14 and 15. This suggests that sensitivity to social media use could be linked to developmental changes, possibly changes in the structure of the brain, or to puberty, which occurs later in boys than in girls.
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. The researchers suggest that that social changes at this age, such as leaving home, may make people particularly vulnerable.
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, the study leader, 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, 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.”
A further complication is that social media use can negatively impact wellbeing, but also the reverse is true, previously reported and confirmed by this study.
The researchers stress that these population-level findings do not predict which individuals are most vulnerable.
Professor Rogier Kievit said: “Our statistical modeling 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 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.”
