Mental disorders affect about 1 in 7 children and adolescents worldwide, with 50% arising before the age of 14. Despite the high burden and early onset, most conditions remain unrecognized and untreated. We mapped evidence on the effectiveness of child and adolescent (ages 0-19) mental health and psychosocial support interventions in low- and middle-income countries within the last 12 years and identified 697 records from 78 countries.

The field is reactive rather than proactive, with most interventions focusing on treatment rather than promotion or prevention. Most mental health research is conducted in educational settings and focuses on early and late adolescence. Research on early childhood interventions as well as evidence to address the mental health and psychosocial needs of children in humanitarian settings are scarce.

Mental health intervention research lacks diversity: less than one third of studies and reviews focused on specific population groups. Despite the known potential for digital interventions to overcome a range of barriers, the field is understudied with very limited evidence across all outcomes. In 60 countries, no research was identified. There were also important geographical disparities and research gaps in West and Central Africa.

Best of UNICEF Research showcases the most rigorous, innovative and impactful research produced by UNICEF offices worldwide. While evidence highlights emerging issues, it also informs decisions and provides policy and programme recommendations for governments and partners, to improve children's lives.

This year, Best of UNICEF Research celebrates its 10th edition. It features 12 research projects that the selection panel concurred deserved special recognition for delivering results for children in 2022. How? By informing decision-making, shaping policy, raising public awareness, driving social change, and giving children and young people a voice on the issues that affect them most through participatory research.

These endeavours showcase both the power of innovation in the face of emergency and crisis, and the virtues of agility, endurance and scalability. They also offer solutions and ways to learn from each other. Each piece of research offers a set of adaptable tools: validated methodologies; templates for emergency response plans; methods of monitoring and measuring progress; and examples of successful collaboration between stakeholders. 

Balancing the need to collect data to support good decision-making versus the need to protect children from harm created through the collection of the data has never been more challenging than in the context of the global COVID-19 pandemic. The response to the pandemic has seen an unprecedented rapid scaling up of technologies to support digital contact tracing and surveillance. As the pandemic progresses, we are also likely to see the emergence of more applications that link datasets as we seek to better understand the secondary impacts of the pandemic on children and their families.

This working paper explores the implications for privacy as the linking of datasets increases the likelihood that children will be identifiable and consequently, the opportunities for (sensitive) data profiling. It also frequently involves making data available to a broader set of users or data managers.

While it is recognized that reuse of unidentifiable data could potentially serve future public health responses and research, the nature of, access to and use of the data now and in future necessitate accountability, transparency and clear governance processes. It requires that these be in place from the outset. These are needed to ensure that data privacy is protected to the greatest degree possible and that the limitations to the use of these data are clearly articulated.

In an era of increasing dependence on data science and big data, the voices of one set of major stakeholders – the world’s children and those who advocate on their behalf – have been largely absent. A recent paper estimates one in three global internet users is a child, yet there has been little rigorous debate or understanding of how to adapt traditional, offline ethical standards for research involving data collection from children, to a big data, online environment (Livingstone et al., 2015). This paper argues that due to the potential for severe, long-lasting and differential impacts on children, child rights need to be firmly integrated onto the agendas of global debates about ethics and data science. The authors outline their rationale for a greater focus on child rights and ethics in data science and suggest steps to move forward, focusing on the various actors within the data chain including data generators, collectors, analysts and end-users. It concludes by calling for a much stronger appreciation of the links between child rights, ethics and data science disciplines and for enhanced discourse between stakeholders in the data chain, and those responsible for upholding the rights of children, globally.
