What is a Public Health Approach? 

A public health approach is a way of understanding and addressing needs holistically. "Holistically" means in a way that deals with the whole of something or someone and not just a part.

The approach includes: 

  • Starting with an understanding of needs at a population level - asking questions like who, what, where, why and how.
  • Addressing the causes of the causes. What lies behind presenting behaviours and situations? Sometimes this is referred to as social determinants, and there is strong evidence for the impact of Adverse Childhood Experiences and Adverse Community Environments.
  • Prevention is better than cure. Prevention can be categorised as primary prevention (stopping something happening in the first place), secondary prevention (early intervention, or stopping an emerging problem getting worse) and tertiary prevention (managing an ongoing problem to prevent crises and reduce harm).
  • Being evidence-based wherever possible (and evaluating where there isn’t clear evidence of effectiveness for an intervention) and using and sharing good quality data.
  • Working in partnership across systems and with communities - because bringing together our varied expertise, experiences and skills helps us to achieve better outcomes. 

Taking a public health approach is not a replacement for response policing, healthcare or individually tailored support - it works alongside these.

The '5Cs' Model

The ‘5Cs’ model describes some principles for partnerships working together to prevent and reduce violence:

In February 2026, Dawn Foster delivered a webinar on behalf of our organisation about the public health approach to serious violence. 

Dawn founded We Do Wellbeing in 2015 to support people to live happier and healthier lives. She has worked on national projects including the development and rollout of the Violence Prevention and Reduction Education Pathway and Making Every Contact Count (MECC) for Mental Health.

Watch the webinar below (47 mins) for an overview of the public health approach and why it’s useful for your organisation.

How we Use the Public Health Approach

Building on the Home Office’s guidance, our public health approach is:

Focused on a Defined Population

We work across the Humberside Police area, which covers the four authorities of East Riding of Yorkshire, Hull, North East Lincolnshire and North Lincolnshire. Some of what we do is universal, meaning everyone (or everyone with particular characteristics, such as certain age groups) may access or benefit from it. Other work is more targeted, for example with the people we have identified as being most at risk of being drawn into violence.

Working With and for Communities

Our work is informed and co-produced by local communities and people with lived experience of violence and its causes. We recognise that we do not have all the answers and a successful approach to preventing violence depends on people and communities getting behind it as much as statutory organisations. Therefore, we take a strengths-based approach, one that avoids labelling, blaming, stigmatising or judging, and seeks to help people and communities to build on their strengths rather than focus on their perceived deficits. We are also trauma aware in what we do and how we communicate - recognising that trauma can have lasting adverse effects on people and communities and that we have a responsibility to prevent re-traumatisation. Our longer-term aim is to be fully trauma-informed across the system.

Not Constrained by Organisational or Professional Boundaries 

We are taking a “whole-system” approach, recognising that a great number of organisations – and teams within organisations – can contribute to preventing violence, but none of them can solve the problem on their own. How well the relationships and interactions between different parts of the system work is as important as how well each part works individually.

Focused on Generating Long-term and Short-term Solutions

Our work is inherently long term. Working on the root causes and determinants of violence means we may not see some of the outcomes for several years, but by drawing on the evidence base and developing a clear theory of change we can be confident of the value of primary prevention. However, we also know that there are things we can do now with people who may be on the cusp of violence to prevent them being drawn in – which in turn may prevent others being drawn in later. We therefore seek to balance our work across the long term and short term.

Based on Data and Intelligence

We pool data across organisations to create new insights and a more complete understanding of the drivers of serious violence in our area. Where appropriate, we use data and intelligence to focus our attention and investment on the cohorts of people with the greatest need.

Informed Evidence of What Works

There is growing evidence about what works to prevent serious violence. Drawing on this helps us focus our resources on the things that are most likely to work and to learn from the experiences of others. However, we do not solely do things that have been tried before. We welcome new ideas, try our own local approaches and (wherever possible) evaluate them to find out whether they work. By doing this, we can contribute to the collective understanding of how to prevent violence, as well as learn from it.
