What is My World Survey 2?

Developed by UCD School of Psychology and Jigsaw, My World Survey 2 is Ireland’s largest and most comprehensive study of young people’s mental health and wellbeing.

It captures the views of more than 19,000 young people from across Ireland to understand what can lead to an increased risk of mental health difficulties, and what can help to protect and support a young person’s mental health and wellbeing.

It builds on the findings of My World Survey 1, the first ever survey of its kind in Ireland, published in 2012.

Why is young people's mental health a big issue for Ireland?

A Big Issue


A third of Ireland’s population, 1.6 million people, is under 25 years old.


Mental health difficulties cost Ireland’s economy €8.2 billion a year.

Mental health difficulties can influence a young person’s cognitive, emotional and social development, educational attainment and their potential to live a healthy and productive life.

Adolescence and early adulthood have been identified as the peak time for the onset of mental health difficulties. Despite this, many young people do not get support at this critical time. This has been described as a “crisis in care” internationally.

Why is this research important?

Understanding what supports and challenges young people’s mental health, and what works best to help them, is vital in helping us to identify what prevents mental health difficulties and what improves outcomes.

Since My World Survey 1 was published in 2012, its findings have been used to inform the development of both practice and policy in Ireland.

Recently, the Irish Youth Mental Health Task Force (2017) recommended ongoing support for large-scale projects that can improve the quality of research on youth mental health issues, such as the My World Survey.

Jigsaw is a charity that provides a range of free mental health supports for young people.

We believe in evidence-informed early intervention. We work with young people (age 12-25) when problems start to develop in an effort to prevent these problems from having a greater effect on the young person’s wellbeing and everyday life.

Our supports include our Jigsaw services situated in 13 communities across Ireland, online through JigsawOnline.ie, and a comprehensive programme of education and training for parents, teachers and those who work with young people.

Our vision is an Ireland where every young person’s mental health is valued and supported.
