Kailo embodies the latest advances in prevention science
Developed by leading experts in the field and committed to measurable impact.
Our structured yet flexible approach is supported by a continuous program of research, development, and rigorous evaluation, resulting in an effective approach that’s grounded in evidence and practical in its implementation.
Why focus on young people’s mental health and wellbeing?
Positive mental health is a fundamental building block for young people to live happy, fulfilling lives whilst making positive contributions to society. However, rates of poor mental health are on the rise across the UK, with 62.5% of mental illnesses emerging by the age of 25 (Solmi et al., 2021).
This underscores the critical need for early intervention. When left unsupported, poor mental health has lasting consequences for individuals, often requiring support from health and social care systems.
Current support systems are overwhelmed and frequently unable to meet the increasing demand for assistance compacting existing issues further.

Understanding the foundations
The social determinants of health are the conditions in which individuals are born, grow, live, work and age. They can be described as building blocks of health. We know they have a larger influence on our physical and mental wellbeing than access to high quality healthcare alone.
These building blocks are shaped by our local contexts, and are unique from place to place. Kailo draws from existing evidence, uncovering the local conditions that matter most to young people – and how they interact as a foundation for mental health.
The power of Co-design
Building strong foundations for young people’s mental health demands the experience, insight and contributions from a diverse range of people.
Young people know what matters to them, by working with them we can ensure that strategies created are both meaningful and relevant. Community professionals bring focus and knowledge of the social determinants and wider levers for change and understanding of existing activities. System leaders can exercise power and resource to make changes a reality. Kailo draws on best-practice co-design approaches, addressing power imbalance and building trust. When these essential voices unite, they create policies that are not only necessary and equitable, but also truly effective and sustainable. This is the power of co-design.

Reshaping the entire context, not just individual parts, is key for lasting progress.
Kailo goes beyond quick fixes and temporary solutions by embracing a systems change approach. This methodology focuses on building enduring infrastructure, redefining processes to shift structures, and nurturing relationships and mindsets.
Evidence into action
The design and development of Kailo is continuously shaped by rigorous research and evaluation, ensuring a balanced approach that integrates practical application with academic precision.
Ongoing evaluation, led by UCL and Exeter University, examines how Kailo contributes to driving systemic change at a local level. Additionally, in collaboration with the Evidence-Based Practice Unit at the Anna Freud Centre, we ensure that existing evidence on effective interventions is accessible and actively informs action.

Making the most of motivations: Why young people attend YPAGs
- This guide is a collection of advice from the two YPAGs about what motivated them to attend the sessions. It is designed to help other researchers in the future to advertise YPAGs in the right way and offer advice about how they can make sessions meaningful and motivating for young people from all different backgrounds.
