A randomized experimental study of sharing crime data with citizens: Do maps produce more fear?

The larger roles of the community in crime prevention and improvements in technology have increased police–citizen communication and the distribution of information from police departments to private citizens. Combined, these changes have led to the current movement among law enforcement agencies toward sharing both summary reports and maps of crime with community groups. Although the dissemination of crime information is intended to benefit community members, there is a lack of empirical evidence demonstrating the effects of crime mapping on citizen perceptions and fear of crime. This experiment compared three formats for disseminating crime data; two popular types of crime maps (i.e., graduated symbol and density) and the traditional tabular format of crime statistics. A randomized experimental design was used to measure residents fear of crime and their perception of the safety of different areas of Redlands, CA. Overall, residents who viewed either type of map reported less fear than those who viewed tabular statistics. Respondents who viewed graduated symbol maps consistently reported less fear than either density maps or tabular statistics. However, there were differences depending on the type of map. While graduated symbol maps were associated with the lowest levels of fear of robbery, theft or assault; density maps produced different reactions depending on the area of the city. Finally, the maps did not stigmatize high crime areas of Redlands. Where statistically significant differences existed, respondents who were given maps were more likely to recommend someone move into an area than those who were given tabular statistics.     

Overcoming Challenges to Using Evidence-Based Interventions in Schools

The Center for School Mental Health Assistance at the University of Maryland recently completed a review of evidence-based prevention and treatment programs that can be used by school mental health clinicians. Based on the review, a school-based program operating in 22 Baltimore City schools has purchased and trained clinicians in a number of protocols for evidence-based interventions. We present findings from this review and make pragmatic recommendations for school mental health programs to overcome the challenges associated with the use of evidence-based interventions.She received her doctorate in childclinical psychology from the University of Missouri-Columbia.
