Practice Summary: Sobriety checkpoints are police operations that aim to reduce the number of alcohol-related car crashes by preventing people from driving under the influence of alcohol and other substances. Driving under the influence (DUI) is prevented by increasing the perceived and actual risk of detection and apprehension by the police. The practice is rated Promising for reducing the number of car crashes.
Gender-Specific Programming for Incarcerated Females
Practice Summary: The practice involves in-prison substance abuse and other types of treatment programs for incarcerated women with the goal of reducing recidivism. The practice is rated Promising.

Procedurally-Just Policing during Traffic Stops (Turkey)
Program Summary: The program involved incorporating elements of procedural justice into traffic stops in Adana, Turkey, to test whether procedural justice improves citizens’ perceptions of the police and the law. The program is rated No Effects. No significant differences were found between the treatment and control groups on general perceptions of the police, but the study did find significant differences between the treatment and control groups in encounter-specific perceptions.
Residence Restrictions for Sex Offenders (Jacksonville, Florida)
Program Summary: In 2005, the city of Jacksonville, Florida passed an ordinance that required sex offenders to reside more than 2,500 feet away from any place where children congregate. The goal was to reduce sex crimes, especially those committed against children. However, the city residence restriction law was later deemed unconstitutional in 2007. The program is rated No Effects. The residence restriction had no significant impact on sex offenders’ rates of rearrests for sex crimes.
School-Based Expressive Writing Intervention for At-Risk Urban Adolescents
Program Summary: This was a school-based intervention targeting at-risk, seventh-grade students. The intervention included either a standard expressive-writing condition or an enhanced expressive-writing condition. The program is rated No Effects. No significant differences were found between the standard writing condition and the control condition, or between the enhanced writing condition and the control condition, on self- and teacher-reported measures of aggression and emotion regulation.
Minnesota Comprehensive Offender Reentry Plan (MCORP)
Program Summary: This was a case management program implemented in seven different correctional institutions across Minnesota. The program connected caseworkers in prisons with supervision agents in the communities to which participants return upon release from prison. The program is rated Promising. It significantly reduced recidivism as measured by rearrest, reconviction, technical violation revocation, and reincarceration for any reason, but had no significant impact on new offense reincarceration.
Home-Visiting Program for Adolescent Mothers
Program Summary: This is a community-based program in which adolescent mothers had regularly scheduled one-on-one meetings with trained home visitors, who delivered a parenting and an adolescent curriculum, created connections with primary care providers, and encouraged contraceptive use and school continuation. This program is rated Promising. The intervention was shown to promote positive parenting attitudes and school continuation, but did not affect mental health, contraceptive use, or repeat teen pregnancy.
Doors and Windows Ordinance (Philadelphia, PA)
Program Summary: This environmental crime-prevention measure was enacted as a city ordinance and required property owners of abandoned buildings (that often serve as havens for illicit drugs and related crime and disorder) to install working doors and windows in all structural openings or be subject to significant fines. This program is rated Promising. Results suggest that this measure is significantly associated with citywide reductions in overall crimes and nuisance crimes, but not violent gun crimes.
