UCL DEPARTMENT OF SECURITY AND CRIME SCIENCE
MISSION: “to identify the best available evidence on approaches to reducing crime (and the potential savings to the police service, their crime reduction partners and the public)”
Structuring our research question
Findings from systematic review or meta-analyses
Broadly defined ‘crime prevention’
Overall aim was to search for evaluations of interventions in all relevant fields that might have a crime prevention outcome
Systematic reviews
• Provide an up-to-date summary of all literature on a topic
• Allow large amounts of data to be synthesised
• Provide an objective collation of results of research
• Provide reliable recommendations
Final number of included studies = 326
Our systematic search flowchart
The crime prevention evidence base
• Commissioned by various stakeholders who frame the research question in myriad ways– By intervention– By problem– By population– By context– By policing strategy– By outcome– By stakeholder
• Implies that all these foci are relevant to practitioner sub-groups
