Guidance for Local Partners in the New Model for Community Justice

Appendix E

Logic Models and Tools to Design and evaluate community justice interventions

Scottish Government Justice Analytical Services ( JAS) have published guidance on how to design and evaluate evidence-based community justice interventions. The guidance fits within an Improvement Framework and includes subject-specific resources and examples throughout.

The " 5 Step Approach" is:

1. Identify the Problem;

2. Review the Evidence;

3. Draw a Logic Model;

4. Monitor your Logic Model; and

5. Evaluate.

What are logic models?

Logic models are step-by-step diagrams which simply show:

• What you're hoping to achieve in the long run (long-term outcomes)
• The process (short- and medium-term outcomes) through which your planned activities can be expected to lead to
  long-term aims
• What resources will you need to do this (inputs)

Anyone who is planning activities with particular aims in mind can benefit from using a logic model. A logic model is also used as the framework for collecting data and evaluating your service. Examples of logic models are given in this Appendix below.

JAS have produced several evidence reviews which may be of use to statutory partners in following this approach:

- What Works to Reduce Reoffending?: A Summary of the Evidence (2015)

- What Works to Reduce Crime?: A Summary of the Evidence (2014)

Current situation: Why is this service needed?
Consider needs, assets, symptoms v. problems, mission, values etc.

A worked example of a logic model approach is given below.

Current situation: Summary: The evidence clearly shows that structured and intensive CBT-based programmes can reduce drug use. However, there are currently no community services in X Local Authority area which has the second highest number of drug convictions in Scotland. Although convicted individuals can access support through the DTTO and CPO requirements, there are an absence of services that can be accessed directly from the community via local GP surgeries.
