Evaluating a sports-based programme to prevent youth violence
Under a grant from the Youth Endowment Fund (YEF), we are evaluating the Dallaglio RugbyWorks (DRW) programme—an intervention that uses sport as a hook to raise aspirations, develop life skills, support mental health, and improve physical well-being.
Young people involved in or affected by crime often experience complex behavioural and emotional difficulties. While sport-based programmes are increasingly used to engage and support these young people, robust evidence of their impact remains limited.
Challenge
The primary research question of the study is: What is the impact of the DRW sports for development programme on the behavioural difficulties of children and young people aged 11-16 who are at risk of or involved in youth violence, gang activity, and/or crime as a perpetrator or victim—compared to business as usual?
Solution
Our team is delivering a rigorous two-arm randomised controlled trial (RCT) involving 900 young people across England and Wales. The evaluation combines a rigorous impact assessment with a process and implementation study and a cost-consequence analysis to determine the programme’s effectiveness and value for money.
The evaluation combines:
- Impact evaluation to assess measurable changes in behavioural and emotional outcomes and a reduction in young people’s involvement in crime.
- Process and implementation evaluation to understand how the programme is delivered in practice.
- Cost-consequence analysis to determine the average cost per young person and assess value for money.
A defining feature of this work has been an in-depth co-design phase with Dallaglio RugbyWorks (DRW). We worked closely with DRW to refine the programme’s Theory of Change, strengthen recruitment and randomisation processes, and minimise attrition. Together, we developed a detailed study protocol and statistical analysis plan (both published), survey instruments, qualitative research tools, and a coaches’ handbook explaining the Theory of Change and trial processes.
The evaluation also incorporates a participatory engagement approach through a Children and Young People’s Panel. The Panel has helped shape information sheets and consent materials, refine research tools, and explore key topics including racism, discrimination, crime and violence, sport, and local environments. This ensures the study reflects the lived experience of Black and other minoritised young people.
Where we are now
In the first year of the study, we achieved 100% completion of the baseline survey and 90% completion of the follow-up survey—exceptional retention rates for a large-scale RCT.
Running through to February 2027, the evaluation will provide robust evidence on whether the Dallaglio RugbyWorks sport-based intervention can meaningfully improve behavioural outcomes and contribute to violence prevention—helping ensure that future investment is directed towards what works.
Our collaborative approach with DRW has supported a constructive and empowering evaluation journey. Ongoing partnership throughout delivery has helped address practical challenges such as maintaining contact with participants and maximising survey completion.
