Below are answers to some of the most commonly asked questions about the Crime Reduction Toolkit. However if you would like any additional information, please email firstname.lastname@example.orgWhat is the Crime Reduction Toolkit? The Crime Reduction Toolkit summarises the best available research evidence on what works to reduce crime. It uses the EMMIE framework to present evidence from systematic reviews of research on crime reduction interventions in a format that helps users to access and understand it quickly.How can the Toolkit help me? The Toolkit can help you to understand what reduces crime (and what doesn't) according to the best available evidence. You can also find out how and where interventions work best, how to implement them and what they might cost. Clicking on the intervention title provides a more detailed summary of the findings.What is the difference between the Toolkit in table form and the Toolkit in bubble form? Both formats draw on the same research evidence relating to the same crime reduction interventions. The main difference between the two formats is the way in which the evidence is presented. The bubble version allows you to access the evidence relevant to the crime problem you are trying to tackle and is designed to be more interactive. The table version presents a straightforward list of the interventions. What is a systematic review? A systematic review summarises the research evidence from a number of studies on a particular topic and uses strict criteria to exclude studies that do not fit certain quality and methodological requirements. Some systematic reviews include meta-analyses which use statistical tests to estimate the overall effect of an intervention by combining data from multiple studies. Only interventions that have been subject to a systematic review have been included on the Crime Reduction Toolkit. How were the studies coded? Our method statement summarises the approach taken to create the What Works Crime Reduction Toolkit. It can be broken down into 4 stages: Stage One: Searching for relevant systematic reviews Stage Two: Devising a system to capture and assess the quality of evidence from systematic reviews Stage Three: Coding the studies Stage Four: Translating EMMIE into a practical toolWhat is EMMIE? Evidence is presented using the framework EMMIE. EMMIE is a rating and ranking system which was developed by academics at University College London to help practitioners and decision-makers to access the evidence-base easily and quickly. EMMIE rates each intervention against the following five dimensions:

The quality scale shows you the quality of the research evidence. This ranges from no information (where we cannot comment on quality) to very good quality where we can feel confident in relying on the findings i.e. most forms of bias that could influence the study conclusions can be ruled out. Read more about the quality scale What is meant by the impact of an intervention on crime? The effect scale shows you what the research evidence suggests about the effect of an intervention on reducing crime. The scale ranges from interventions which show an overall decrease in crime to those which show an overall increase. Read more about the effect scale Definitions of terms
The factors filters (e.g. alcohol, drugs, gangs) are applied to interventions that are explicitly linked to that particular factor. Interventions can be linked to factors by the focus of the intervention itself (e.g. Policies related to alcohol sales – so are linked by 'alcohol') or by the outcomes the intervention has been tested against (e.g. the effectiveness of youth curfews has been tested specifically on gang-related crime).
Some interventions in the toolkit may also be effective at tackling factors related to crime, but if they have not been explicitly linked to such factors, the filter has not been applied.
Factor filters are always applied to Problem Orientated Policing (POP). POP is a problem solving approach to develop targeted interventions, rather than an intervention per se. Therefore, a POP approach can be applied to any crime and disorder problem.
