Welcome to the EIP Matrix

Welcome to the EIP Matrix

The fidelity with which an intervention is implemented affects how well it succeeds1. For instance, two studies examining programmes to help people with mental health issues obtain employment found that employment outcomes among their study groups were weakest for those in poorly implemented programmes2‚Äč. Achievement of high fidelity is one of the best ways of replicating the success of interventions achieved by research that has led to NICE guidelines. The EIP Matrix is a fidelity tool aimed at helping mental health providers and commissioners to understand the fidelity and performance of their EIP services3.

The framework is based on evidence drawn from:

  1. NICE guidelines for Psychosis and Schizophrenia based on proven efficacy, effectiveness and acceptance
  2. Expert opinions gathered through surveys of experts and literature reviews
  3. Opinions of users of EIP and their advocates regarding what works
  4. Site visits to a range of EIP services across the UK

Why Fidelity?

Fidelity measures are important because they provide valuable information to three key stakeholder groups:

  1. People accessing the EIP Team and/or their families want to know if the services they are entrusting with their support, treatment and care are up to par and can reasonably be expected to promote the outcomes they care about;
  2. Commissioners want to know if they are getting what they are paying for;
  3. Managers and Leaders want to know whether clinical staff are implementing the interventions as recommended and achieving optimal outcomes over time;
