What we know from the research on preventing violence

Those involved in violence are likely to be vulnerable in multiple, interrelated ways and many may have experienced past victimisation and trauma. A lot of research has examined the relationship between exposure to what researchers have called ‘adverse childhood experiences’ – or ACEs in the research literature – and violent offending.

Adverse childhood experiences take on many forms, such as the death of a parent or close friend, household criminality, exposure to domestic abuse, substance misuse or bullying, and difficulties with health, communication or learning. These experiences can increase vulnerability to violence. In short, ACEs are a form of trauma, or series of traumas, experienced during the important, formative stages of a life.

We try to minimise these risk factors and instead build resilience. The Violence Reduction Unit commissions research to inform future approaches and provides funding to projects and programmes that target prevention at individuals.

Online harms experienced by children and young people

In light of the increased amount of time young people spent online during the pandemic to learn, socialise and for entertainment, London’s Violence Reduction Unit (VRU) commissioned an in-depth exploration of online harms, ‘acceptable’ use and regulation, that included the experiences of young people, whose voices were missing from the body of existing research.

As part of the Social Switch Project, well respected charities, Catch22 and Redthread, carried out interviews with vulnerable children and young people that use its services, as well as frontline youth workers, police and tech platforms.

MyEnds impact evaluation: Main report

London’s Violence Reduction Unit promotes local, place-based and community-led approaches to reducing violence.

In 2021, the VRU developed the ambitious MyEnds programme, allocating a total of £6 million (including an evaluation piece) to provide support, capacity, and funding for locally designed interventions in neighbourhoods affected by high and sustained levels of violence.  

This independent evaluation report, produced by Cordis Bright, highlights emerging impact, strengths, promising practice and learning from the first two years of MyEnds. The evaluation took a mixed methods approach which included: interviews, observation, e-survey, document review, data analysis, and deep-dive case studies.

Youth-led participation: Young People's Action Group

London’s Violence Reduction Unit (VRU) is committed to a Child First approach, centred on putting children and young people at the heart of everything we do.

The VRU’s approach has been to embed the voice of young people in its work to tackle violence and to provide and support access to opportunities for young people, families and communities. A passion and determination to embed young people in all aspects of work led to the development of the Young People’s Action Group (YPAG).

Our information guide has been created to support organisations of any shape and size to meaningfully work alongside young Londoners.

The impact on young people of police using images of knifes in social media posts

London’s Violence Reduction Unit was asked by its Young People’s Action Group (YPAG) to examine concerns of images of knives and dangerous weapons seized by the police being published on social media.

The YPAG were concerned that posting images of knives seized by the police on social media could contribute to a sense of fear in communities, particularly amongst young people.

As a result, the VRU commissioned research – led by University College London – to investigate the impact on young people of using knife imagery in social media posts. This was done by exploring the impact that images of knives have on young people’s perceptions of safety in London, the level of knife carrying as well as the fears and attitudes of seeing images of knives posted online.

Understanding homicide: a framework analysis

London's Violence Reduction Unit commissioned the Behavioural Insights Team to create a framework to help us better understand homicides, how situational and behavioural factors interact, and how we can work in partnership to identify opportunities to intervene earlier.

This report sets out how we've taken complex case notes on 50 homicides and turned them into consistent data. It helps us to answer complex questions, such as how many homicide victims knew their perpetrator, or the role social media plays in the run up to a homicide. Following its initial success, the framework will now be used to analyse a further 300 cases with a view to it potentially being used more routinely in the capital.

Neighbourhoods affected by violence

Commissioned by the VRU, this research focused on nine local areas in London to examine violence and has reinforced understanding of the known drivers of violence, including poverty, austerity cuts and racism.

Based on these drivers of violence, the report provides 10 recommendations for the VRU to consider and act upon.

Child/adolescent to parent violence and abuse

London’s Violence Reduction Unit commissioned new research to improve our understanding of the prevalence and nature of children and young people's use of violence and abuse towards parents/carers in London.

The VRU analysed a range of data and consulted with communities to understand the needs of parent/carers in London. A theme that consistently featured as an area of concern for parents and carers was Child/Adolescent to Parent Violence and Abuse (CAPVA).

Violence in London: what we know and how to respond

In 2020, the VRU commissioned the Behavioural Insights Team (BIT) to develop a Strategic Needs Assessment to inform its approach to violence prevention in London.

The report, called ‘Violence in London: what we know and how to respond’, identifies current and future health needs of local populations to inform and guide the planning of services within a local authority area and pave the way for significant reductions in violence now and for future generations of Londoners.

A report on the London Violence Reduction Unit

Our first Annual Report sets out what we’ve achieved. It delves into how we are governed and scrutinised, the data and evidence we have drawn on, the partnerships we have forged, and the programmes we’ve funded.

It answers the questions specifically set by the Home Office and critically describes our learning and analysis about what works.

Project 10/10

Project 10/10 is a collaboration between Camden and Islington NHS Foundation Trust, Camden Council, Coram's Fields and MAC UK.
London's VRU funded new research by Project 10/10 to develop greater insight and learning of community-based crisis intervention and trauma support for young people.

The report identifies examples of barriers to accessing services and how to overcome them.
