Our latest researcher of the month, Roxana Pomplun, has investigated the interactions, experiences and perceptions of younger adolescents, aged 11, 12, and 13, with algorithmically curated platforms such as TikTok, YouTube Shorts, Spotlight on Snapchat and Reels on Instagram. These kinds of platforms use algorithms to personalise and tailor feeds, harnessing user data to suggest content that the individual is most likely to be interested in and engage with. As such, young people have little control over what they are seeing in their feeds. Tech companies are not yet required to be transparent about the data that they are collecting, but it tends to include demographic information such as age, gender or location, along with use patterns. 

Whilst these sites dominate the digital lives of tweens and teens, until now they have received little dedicated research attention, particularly in relation to younger users, with most existing studies focusing on older teens. 

Whilst we know that most social media platforms have age limits of 13, we also know that many younger children are active users, particularly of algorithmically curated platforms like TikTok and YouTube Shorts. Given that early adolescence is a life phase marked by critical neurological development, identity development and heightened susceptibility to mental health issues, deepening our understanding of how younger adolescents engage with social media is vital. 

Roxana's qualitative research, where a group of young people eloquently explore their own experiences and perceptions, broadens our knowledge of social media use within an age group that appears increasingly aware of the digital influences shaping their online experiences, yet which is still in need of support to fully navigate these ecosystems.

Roxana has just passed the viva voce for her NIHR-funded PhD in Applied Health Research at the University of Kent. Her research has focused on younger adolescents’ (aged 11-13) interactions with algorithmically curated social media, particularly short-form video platforms (e.g. TikTok, YouTube Shorts). Roxana has now started working as a Child Safety Researcher at ActiveFence, continuing her aspiration for making the internet a safer place for children and young people.

Roxana's research focuses on younger adolescents’ (aged 11-13) interactions with algorithmically curated social media, particularly short-form video platforms (e.g. TikTok, YouTube Shorts). Her findings are currently being prepared for publication.

Over the last year or so, there has been a surge in public concern around smartphones and social media. Banning or restricting children’s access to smartphones and social media has grasped the attention of policy makers, schools and parents. A number of countries, including France, Turkey, Norway, Sweden, and regions of the US and Canada have introduced laws, policies or guidance for schools to ‘ban’ or heavily restrict the use of phones. In the UK, there are proposals to raise the age of ‘internet adulthood’ from 13 to 16, and to ban smartphones in schools. The third reading of a 

 on this topic will be heard in parliament in July.

Whilst these bans aim to protect children from harm, recent studies highlight a lack of evidence on their efficacy. 

Along with a team of international experts, our latest Researcher of the Month, Dr Victoria Goodyear, 

 that, in isolation, banning smartphone and social media access fails to equip children for healthy use of technology. She suggests that there is a need to shift debates, policies and practices away from a sole focus on restricting smartphone and social media access, toward an emphasis on nurturing children’s digital skills for healthy technology use, and a rights-respecting approach which is underpinned by age-appropriate design and education.

As well as providing numerous opportunities for exploration, joy, and expression, outdoor and adventurous play - the type of play that allows children to take age-appropriate risks - is associated with a range of positive health behaviours and outcomes. Yes, we're talking about the kind of play that might leave us adults with our hearts in our mouths at times, as children start to disappear up a tree, or engage in a rough and tumble game of chase. But its benefits are wide-ranging and known impacts include increased levels of habitual physical activity alongside better mental health and positive mood. 

 In 2019, Dr Hesketh was involved in the creation of 

 in the UK, which explicitly note the importance of outdoor play for children in the preschool age group. We know quite a lot about the play habits of school-aged children, but until now, have had significantly less data on their younger counterparts. 

Our Researchers of the Month, Dr Kathryn Hesketh and Professor Helen Dodd set out to discover how much time preschool-aged children spend playing in a range of indoor and outdoor spaces, and how adventurously they are playing within them. In the first national survey of play in children of this age, they asked over 1000 parents of two to four year olds about their children’s play habits, finding that, on average, children aged two to four spend around four hours per day (outside of educational settings) playing. Just under 50% of this was spent playing outdoors. Their findings shed interesting light on some inequalities in play, even in the youngest age group, which may exacerbate existing inequalities in health.

Bullying is an extremely important public mental health risk. Around one in five primary school children report being bullied at least weekly. Children who are bullied are more likely to experience depression and anxiety, and are at heightened risk of mental health issues in adolescence and adulthood. Whilst schools in England and Wales are required to have anti-bullying policies, rates of bullying remain high. Bullying is preventable, but schools need more help to tackle it. Typically, school policies focus on how to handle bullying once it happens. However, evidence suggests that a comprehensive approach involving the entire school to prevent bullying, alongside clear strategies for addressing confirmed cases, is the most effective way to tackle the issue.

 is one such whole-school approach, developed in Finland by 

. A large study in Finland which involved 28,000 primary school pupils found that adopting the KiVa programme in Finnish schools significantly reduced bullying and improved children's mental wellbeing. The programme has since been rolled out nationally by the Finnish government and ongoing use of KiVa in Finnish schools is associated with year-on-year incremental reductions in bullying.

Along with colleagues, our researcher of the month, 

, has tested the effectiveness of the KiVa Programme in UK primary schools. The study involved over 11,000 children in Wales, Birmingham, Oxfordshire and Devon, and showed a 13% reduction in reported rates of bullying when compared with existing school approaches to tackle bullying.

Since the 1980s, Professor Hutchings has developed, researched and published extensively on parenting programmes, targeting parents of young, mainly preschool, children with a focus on addressing social
disadvantage. Her work has been pragmatic, working with the staff of statutory and voluntary agencies as a consultant clinical psychologist within the NHS and a researcher in academia. Professor Hutchings worked with the Westminster Government through the 2000s supporting the Sure Start initiative and contributing to Cabinet office discussions.

Dr Kim Sylwander

Currently, children's and young people’s use of digital technology is rarely out of the news. Age limits are debated. Calls for stronger limits are made, and questions are raised regarding whether society should ban 'under-age' children from various aspects of the digital world. 13 years of age is often cited as a digital 'age of consent', though this varies in some countries. Commonly used age limits are largely arbitrary, based primarily on US legislation, rather than evidence. In a 

, our researcher of the month, Dr Kim Sylwander, and her co-author Professor Sonia Livingstone, consider age milestones and evaluate whether or not the evidence supports them. 

Are age limits the optimal way to regulate children’s digital experiences? Does it matter that they are widely contested and often poorly implemented? And are common boundaries even the “right” age, according to evidence from the field of children and digital media? Dr Sylwander persuasively argues that moving forward, a developmental approach can better support children’s rights.

Dr Kim Sylwander is a postdoctoral researcher at the 

 research centre at the London School of Economics and Political Science. This joint LSE and 

 centre facilitates research for a rights-respecting digital world for children. Dr Sylwander holds a PhD in Child and Youth studies and has conducted post-doctoral research at the Centre for Sexology and Sexuality Studies at Malmö University. She has also been an appointed expert in government inquiries in Sweden on sexual exploitation and the effects of digital media on children. Her work has focused on children, youth and media, touching on issues such as online hate, racism, bullying, sexuality, sexualisation, digital gender-based violence, consumption of pornography, and online child sexual exploitation and abuse. Dr Sylwander has headed various research projects within academia, the UN, civil society, and within government agencies. Her current research projects focus on children’s rights in the digital world. She is currently researching the impact of the UN Committee on the Rights of the Child’s General comment no. 25; the evolving capacities of children in relation to their rights in the digital environments and she is also involved in projects on children’s visions of digital futures and AI.

Professor Li Zhao

A new study which explores the development of trust and integrity in children has found that expressing trust in young children encourages them to behave honesty. The research team, including our researcher of the month, Professor Li Zhao, studied whether children were less likely to cheat in a simple test of counting accuracy if the adult administering the test had previously conveyed trust in them. They found that children who were trusted cheated less than those who were not trusted. These findings provide novel evidence about the causal effect of trust on the development of children's honesty.

Professor Li Zhao was made Professor of Psychology at Hangzhou Normal University, China in 2018. Between 2019 and 2020, she was also a visiting scholar at the Graduate School of Education, Harvard University in the US.

Showing faith and trust in children nurtures integrity

Professor Saloni Krishnan and Professor Pablo Ripollés

From infancy onwards, humans display an innate motivation to acquire language and to communicate. We start acquiring words as babies and continue to do so throughout our lives. In fact, children are thought to learn over 3000 new words each year. However, relatively little work has focused on why we are motivated to learn words, particularly when it comes to adolescents. 

Adolescence is a period of great neurological change and sensitivity to learning. It's also marked by changes in reading behaviours. Whilst children become skilled readers between the ages of 10 and 18, this period is also associated with motivational changes in reading, with teens frequently showing a disinclination to read for pleasure. This change often coincides with the transition from primary to secondary school.

Intrinsic reward and word learning

Dr Natalie Brown

Research has shown that menstruation and menstrual cycle symptoms can be disruptive and detrimental to physical, mental and social wellbeing. As many as 93% of teen girls experience dysmenorrhea (severe cramps) and girls with a typical cycle experience 11 menstrual cycle-related symptoms on average, potentially including mood changes, stomach cramps and increased levels of anxiety and fatigue. Adolescents with problematic symptoms have reported a negative impact on school attendance, behaviour, confidence around peers and participation in physical activity.

Dr Margarita Panayiotou

A significant body of evidence tells us that young people's mental health has decreased over time, and a potential link between social media use and this mental health decline has triggered wide interest and concern. Research into social media use and mental health is being conducted at a rapid pace but, so far, findings are far from conclusive. Our new Researcher of the Month, Dr Margarita Panayiotou, adds to this body of work. She led a team of researchers who recently published a 

 involving thousands of young people in the UK. It set out to explore the interplay between social media use and teens' mental health, wellbeing and social life, and found that when considering the complex combination of multiple factors, things such as a lack of family support are arguably more important for adolescent mental health than social media use.

How influential is social media on young people's mental health?

Dr Caoimhe Dempsey

We already know that children's relationships with their parents and teachers contribute to their school adjustment and achievement, and that positive, close relationships with adults are really important for a wide variety of children’s outcomes. However, few studies have examined interactions between these relationships or sought to address the nuances of children’s experiences in terms of how different relationships have different impact or influence.

To address this, along with colleagues, our new Researcher of the Month, Dr Caoimhe Dempsey, has recently published an 

 which aims to examine the links between children's relationships with their mothers, fathers and teachers, and three domains of school adjustment: academic achievement, academic self-concept and behavioural adjustment in the classroom. By examining a range of data, the researchers sought to find out whether some children are more susceptible to the effects of the quality of their relationship with their teacher.
