Evidence Based Practice Unit (EBPU)

The Evidence Based Practice Unit bridges cutting-edge research and innovative practice in children’s mental health. Our vision is for all children and young people's wellbeing support to be informed by real-world evidence so that every child thrives. We conduct research, develop tools, provides training, evaluate interventions and disseminate evidence across four themes: risk, resilience, change and choice.

Our work spans a wide range of areas within children and young people’s mental health. This includes designing and evaluating digital mental health tools; collecting and analysing longitudinal data, both qualitative and quantitative, to understand change over time in young people’s wellbeing; supporting schools and colleges to carry out wellbeing surveys; and investigating mental health and wellbeing programmes in a variety of settings including education settings, community settings and specialist services.

Equity, diversity and inclusion are key to our research strategy and we aim to unpack the best ways to support the mental health of young people with marginalised identities, who may experience a combination of structural and social inequalities.

Evidence Based Practice Unit logic model

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

We developed the Evidence Based Practice Unit 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 Evidence Based Practice Unit logic model helps people to clarify their thinking and enables them to define appropriate evaluation strategies more clearly. We have also found that even in this simplified form, it takes time to understand how to use the logic model and to include the right level of information in each column. Our booklet to guides users through the process.

The booklet consists of the following sections: 

1. A blank template for the Evidence Based Practice Unit 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.
