In response to growing concerns about youth mental health and well-being – concerns that have intensified in the wake of the COVID‑19 pandemic – many countries have expanded actions to promote youth mental health and emotional well-being, adopting a wide range of approaches (IPPO, 2023[107]; OECD, 2025[4]). Policy responses can emerge from multiple ministries. Policy strategies are often anchored in health policy and led by ministries of health, but they may also be embedded in broader plans to promote youth well-being led by ministries of social affairs (Dirwan and Thévenon, 2023[108]), or implemented through initiatives supported and delivered within education systems under the responsibility of ministries of education (OECD, 2024[109]). An additional priority is ensuring that policies align with adolescents’ own concerns and effectively support their social and emotional well-being. This has led to a growing emphasis on recognising children as rights-holders and involving them as active participants in decision making processes that affect their lives (OECD, 2024[109]).
For younger adolescents, initiatives to support children and adolescents’ well-being and mental health include school-based interventions, community-based initiatives, the development of digital and telehealth resources, awareness-raising and anti-stigma campaigns, as well as rebates or subsidies for mental health treatment (OECD, 2025[110]). Evidence from impact reviews suggest well-implemented universal school-based social and emotional learning (SEL) programmes can help prevent anxiety and reduce bullying, while more intensive and targeted interventions (for example, depression prevention) can be provided to those with greater needs within a co‑ordinated, tiered system of support (Kuosmanen, Clarke and Barry, 2019[111]).
Although the number of rigorously evaluated SEL programmes remains limited, available evidence indicates that both activity-based interventions – where participants actively engage in structured tasks – and education-based (psychoeducational) programmes – focussed on building knowledge about emotions, mental health, and coping skills – can improve adolescents’ social and emotional well-being (Lam and Lam, 2023[112]). In addition, a range of promising practices aim to improve access to care, including free consultations with mental health professionals, youth walk-in centres, and online support tools, helping to address issues early before they escalate. At the same time, a growing number of policies seek to address children and adolescent’s online behaviours – either by promoting safer digital environments by design or through precautionary measures such as social media restrictions or smartphone bans in schools. However, robust evidence on their effects on mental health remains limited. (OECD, 2026[3]).
The scientific literature points to multiple, intersecting risk factors for poor youth mental health, as also highlighted in a recent survey of policy and clinical experts (OECD, 2026[3]). Some of these risk factors are relatively new and societal in nature – such as digitalisation and climate anxiety – meaning that addressing them extends beyond individual responsibility or the scope of service‑based support alone. Other factors, including global conflict and political instability, have long posed mental health risks but may now be experienced more directly and widely by young people due to increased exposure to information. By contrast, several long-standing risk factors are more directly amenable to intervention through adequate social, educational, family and mental health support, including economic insecurity and poverty; school environments and academic pressure; bullying and cyberbullying; information overload; and feelings of hopelessness and fear about the future.
Addressing these risks requires a comprehensive, multi-sectoral response. Experts interviewed by the OECD (2026[3]) consistently emphasised that mental health services alone are insufficient, and that a broader approach involving education systems, families, digital policy, and community-based support is essential. Frequently cited priorities included improving early childhood education and school environments, expanding access to mental health support (including peer support), and strengthening psychosocial education and mental health literacy. Experts also underscored the importance of supportive family environments and parenting skills, healthy lifestyle behaviours (such as adequate sleep, physical activity, and nutrition), strong social connections, and the management of online behaviours through digital literacy and balanced screen use. Overall, the findings point to the need for a holistic, multi-sectoral strategy to build youth resilience, with specialist mental health services playing an important but necessarily limited role.
Within this broad focus on young people under the age of 25, the specific needs of younger children and adolescents warrant particular attention. Childhood is a distinct developmental period in which well-being, learning, and physical, emotional and social development require sustained care and support. Adolescence, in particular, is marked by profound transitions. Alongside the physical changes associated with puberty, young people experience a growing need for autonomy and gradual emancipation from the family environment. In this process, they explore and construct their personal identities, shaping how they perceive themselves, their relationships with others – both girls and boys – and their sense of “living well,” a core dimension of subjective well-being during development (OECD, 2026[8]).
As adolescents’ worlds expand, friendships and peer influence play an increasingly central role, as do the norms, ideals, and stereotypes conveyed across the different environments they navigate daily: within families, at school, among peers, and in digital spaces. Managing these changes can be challenging. As seen in section 2, a substantial minority of adolescents report feeling unwell during this period, with difficulties manifesting in diverse ways, including lower life satisfaction, anxiety, heightened stress, negative self-perceptions or body image, aggressive behaviour, and, in more severe cases, self-harm or suicidal behaviours. Importantly, both the form and intensity of these experiences often differ between girls and boys.
Addressing these challenges requires support that goes beyond parental care or the intervention of a single specialist once difficulties are identified or diagnosed. Effective support must be cross-cutting, embedded across the multiple environments adolescents inhabit, and equipped to detect early signs of distress before problems intensify. Early identification and prevention are essential to help young people navigate this developmental stage and thrive under supportive conditions.
Recognising emerging difficulties is particularly challenging because distress can manifest differently among boys and girls and may remain unnoticed or be normalised due to prevailing social norms. This underscores the need for greater awareness across adolescents’ everyday environments, and supports that are responsive to boys’ and girls’ specific patterns of vulnerability.
While the causes of adolescent distress are multifaceted and cannot be reduced solely to challenges related to norms of femininity and masculinity and identity formation, navigating these norms represents a significant pressure. These pressures may be particularly acute today given the growing tensions, contradictions and uncertainties surrounding societal expectations of boys and girls, as discussed in the previous section.
Overall, adolescents require co‑ordinated and sustained support across the multiple environments that shape their daily lives: the home, school, neighbourhood and community spaces, and the digital environment. The home plays a central role, as parents are adolescents’ primary caregivers and sources of support; however, communication around puberty, identity development and socio‑emotional challenges is not always easy, and parents may lack awareness of the pressures children face in their everyday environments or feel ill-equipped to respond to questions and concerns – particularly those related to norms of femininity and masculinity. In addition, not all parents have equal opportunities to spend quality time with their children to address these issues, due to work constraints, financial stress, or poverty.
Schools are critical settings for addressing barriers to learning that may affect boys and girls differently, fostering socio‑emotional skills, and providing safe and structured spaces where young people can discuss relationships, identity and social norms. Beyond school, neighbourhoods and community settings can be strengthened to offer safe “third places” where adolescents can meet, exchange views, receive guidance from older peers and trusted adults, and engage with positive role models and diverse perspectives in inclusive and empathetic environments.
The digital environment also warrants particular attention, as it increasingly shapes normative representations, social comparisons and expectations against which adolescents evaluate themselves and others. Promoting positive, safe and supportive digital spaces is therefore essential to adolescent well-being.
Finally, health environment – encompassing healthcare services and related supports – is equally important in providing medical and psychological care, as well as strengthening prevention.
Taken together, the interdependence of these environments highlights the need for integrated, cross-sectoral approaches to support adolescents’ social and emotional development and well-being. Supports across these domains should also recognise the distinct challenges faced by girls and boys, as well as the different ways in which social expectations and norms of femininity and masculinity can shape their experiences, vulnerabilities and well-being (World Health Organization Regional Office for Europe, 2011[113]; UNICEF, 2024[114]).
The following section focusses on the challenges that can be addressed through strengthened support in families, schools, and communities, while leaving aside those related to healthcare systems, which are examined in other reports (OECD, 2025[4]).
