Impact Review 2025/26: Self-harm Matters HIT

The Self-harm Matters HIT brings together researchers, practitioners and public health professionals with an interest in self-harm and suicide prevention, alongside those with lived experience. The HIT aims to support access to services for those who self-harm, increase awareness of why people self-harm, and strategies that may be helpful for those who often struggle to get the right support, referral and intervention. Here are highlights from the HIT in 2025/26.

  • 3rd June 2026

New co-directors

The HIT welcomed two new co-directors during the year:

  • Marina O’Brien, Second Step
  • Helen Yeo, Mental Health Programme Lead for Young People at North Somerset Council

Their expertise and leadership strengthen the HIT’s ability to connect research, policy and practice across the region.

Self-Harm Technical Briefing

The HIT’s Self-Harm Technical Briefing, available on the ICB website, highlights the unmet needs of people who self-harm in community settings and provides evidence to inform improvements in support and services.

The briefing is already being used to raise awareness and influence discussions. For example, the Avon Longitudinal Study of Parents and Children (ALSPAC) referenced the briefing during a meeting with House of Commons Library researchers to highlight the vulnerability of young people who self-harm and the links between self-harm and ongoing mental health challenges.

This work has also demonstrated the HIT’s growing role in supporting knowledge exchange between researchers, policymakers, practitioners and people with lived experience.

Research

University of Bristol researcher Dr Bushra Farooq has worked with the HIT to investigate how Adverse Childhood Experiences (ACEs) affect young people’s mental health outcomes, including self-harm and depression.

Her research found that exposure to ACEs over time can increase the risk of self-harm and depression during adolescence and early adulthood. The findings highlight the importance of providing support early in life and throughout childhood to reduce the long-term impact of adverse experiences.

With support from the HIT, Bushra published two research papers:

  • The association between longitudinal patterns of adverse childhood experiences, and self-harm and depression in adolescence and early adulthood: findings from the Avon Longitudinal Study of Parents and Children
  • Longitudinal Patterns of Adverse Childhood Experiences and ‘NEET’ (Not in Education, Employment or Training) Status in Young Adulthood

Public contributor progress

Public contributors Chrissy and Carl have played an important role in delivering Trauma-Informed Training with Second Step, sharing their lived experience to inform and support researchers to embed a trauma informed approach to their research and develop confidence at power sharing with people with lived experience. Feedback has highlighted the value of hearing directly from people with experience of mental ill health, helping researchers to adapt their research process around the needs of different communities.

Both public contributors have also supported research applications and co-facilitated with University of the West of England focus groups in Swindon and Bristo,  to ensure a trauma informed approach to generating insights that support grant development
