EBPU Logic Model

Gaining conceptual clarity on the logic underpinning complex interventions is a key priority in child mental health and beyond.1 A number of approaches for producing logic models for complex interventions have been developed.2

We developed the EBPU Logic Model to be as simple and accessible as possible. This one-page template for a logic model was first developed by Dr Helen Sharpe when she was working at the Evidence Based Practice Unit and has since been used in a wide variety of projects.

We find that the EBPU Logic Model helps people to clarify their thinking and enables them to debate appropriate evaluation strategies more clearly. We have also found that even in this simplified form it still takes some time to understand how to use it and to include the right level of information in each column.

We have produced this booklet to guide others through the process. This booklet comprises the following sections:

  1. A blank template for the EBPU Logic Model
  2. A step-by-step guide on how to complete a logic model
  3. A worked example. It should be possible to apply the model to any intervention.

 The Logic Model is available here.
