Scientists find that the impact of social media on wellbeing varies across adolescence

Summary: Girls and boys might be more vulnerable to the negative effects of social media use at different times during their adolescence, say an international team of scientists. The researchers show that, in UK data, girls 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.

In a study published today in Nature Communications, the researchers show that, in UK data, girls 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.

In just over a decade, social media has fundamentally changed how we spend our time, share information about ourselves, and talk to others. This has led to widespread concern about its potential negative impact, both on individuals and on the wider society. Yet, even after years of research, there is still considerable uncertainty about how social media use relates to wellbeing.

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 periods 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.

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."

Arts activities may improve self-control and reduce antisocial behavior among teenagers

Summary: Teenagers who take part in arts and cultural activities, such as dance, drama, reading and going to concerts, are less likely to engage in antisocial and criminalized behavior up to two years later, according to a new study. Researchers looked at data from more than 25,000 teenagers in the United States who had filled out questionnaires over several years.

Teenagers who take part in arts and cultural activities, such as dance, drama, reading and going to concerts, are less likely to engage in antisocial and criminalised behaviour up to two years later, according to a new study by UCL (University College London) and University of Florida researchers.

For the peer-reviewed study, published in the Journal of Youth and Adolescence (JOYO), researchers looked at data from more than 25,000 teenagers in the United States who had filled out questionnaires over several years.

They measured the teenagers' overall engagement with arts activities based on a wide range of factors, from involvement in school clubs, orchestras, choirs, and arts classes outside school, to whether they had visited museums or been to concerts, or read on their own.

They found that the more of these activities the teenagers were involved in, the less likely they were to report being engaged in antisocial behaviour -- ranging from misbehaving at school, to getting into fights, to criminalised behaviour such as stealing and selling drugs -- both at the time of the first survey and when they were asked again about antisocial behaviour one and two years later.

The team also found that teenagers and young people who were more engaged in the arts were likely to have better self-control scores and view antisocial behaviour negatively. These outcomes have previously been found to make young people less likely to engage in antisocial and criminalised behaviours.

The research was carried out as part of the EpiArts Lab, a National Endowment for the Arts Research Lab.

Senior author Dr Daisy Fancourt (UCL Institute of Epidemiology & Health Care) said: "Past research has shown that getting involved in the arts can have a big impact on teenagers' mental health and wellbeing.

"Our study adds to evidence about the wide-ranging benefits that arts and culture can have for young people, demonstrating a positive link between the arts and a lower prevalence of antisocial behaviour.

"Notably these findings remained, even when taking into account factors such as children's age, gender, ethnicity, socio-economic background, their parents' educational background, where they lived, and their previous patterns of antisocial behaviours."

Lead author Dr Jess Bone (UCL Institute of Epidemiology & Health Care) said: "Our definition of arts and cultural engagement was very broad. It included dancing and acting in school clubs, reading, going to cinemas, museums, concerts, and music classes, as well as other hobbies that teenagers took part in regularly.

"Finding ways to reduce antisocial behaviour among teenagers is important because these behaviours may become established and continue into adulthood, affecting someone's whole life.

"Our findings demonstrate the importance of making arts and cultural activities available for all young people, particularly in the wake of the Covid-19 pandemic, which has limited access to and funding for these resources."

Researchers looked at data from two US-based longitudinal studies, the National Longitudinal Study of Adolescent to Adult Health and the National Education Longitudinal Study of 1988, whose participants were nationally representative. The research team analysed questionnaires filled in by teenagers and their parents between 1988 and 2002. The average age of participants at the start of these studies was 14 to 15 years.

In one of the cohorts, about half of adolescents reported engaging in antisocial and criminalised behaviours in the last 12 months. The average number of times participants engaged in these behaviours over the year was 1.6.

Although the researchers found that arts engagement was linked to fewer positive perceptions of antisocial behaviour and better self-control scores, they could not conclude that these factors were causally responsible for the association between arts engagement and antisocial behaviour as the study was observational.

Nonetheless, in considering mechanisms through which the arts could reduce antisocial behaviour, the researchers cited previous studies showing improvements from arts engagement including increased empathy, more prosocial behaviour, reduced boredom and improved self-esteem, as well as better emotion regulation.

The research was funded in part by the National Endowment for the Arts, Bloomberg Philanthropies, the Pabst Steinmetz Foundation, and Arts Council England.
