Intervention Fidelity (IF) services

Ensure your programme is delivered as intended, every time. 

At the Leicester Diabetes Centre, we understand that the success of any health or behaviour change intervention depends not only on its design, but on how consistently and accurately it is delivered. That’s why we offer a robust Intervention Fidelity Service to help organisations maintain the integrity and effectiveness of their interventions. 

Why Intervention Fidelity matters 

Intervention Fidelity refers to the degree to which an intervention is delivered as intended by its developers. High fidelity means your intervention is more likely to achieve its desired outcomes. Poor fidelity, on the other hand, can lead to inconsistent results, diluted impact, and difficulty evaluating success. 

Whether you're researching health education programmes, digital behaviour change tools, training interventions or clinical pathways, we can help you monitor, assess and improve delivery fidelity so you can be confident in your outcomes. 

What we offer 

Our expert team can support your organisation with: 

  • Fidelity tools design 

We co-create tailored fidelity tools, including bespoke checklists and coding manual, to suit your specific intervention, identifying key components that must be delivered to maintain effectiveness. Key components may include key content, behaviour, or behaviour change techniques of the intervention. 

  • Training and support materials 

We develop high-quality training materials, and guides to support your delivery staff in maintaining fidelity. 

  • Monitoring 

We offer independent monitoring to measure fidelity using a variety of methods, including session observations, recordings, data reviews and structured feedback tools. 

  • Fidelity analysis and reporting 

Our team analyses fidelity data to provide clear, actionable reports. These insights help you understand what’s working, what can be improved and whether the intervention was delivered as intended. 

  • Ongoing improvement support 

We work with your teams to embed fidelity practices into everyday delivery, offering refresher training, coaching, and process improvement strategies.
