Summary View help for Summary
This dataset is from an evaluation of an intervention program designed to facilitate disengagement from gangs and desistance from crime. Led by the Gang Reduction Initiative of Denver (GRID), a multidisciplinary team and street outreach workers carried out the randomized controlled trial between 2019 and 2022. One hundred forty-three people referred to GRID were assigned at random to receive individualized, coordinated case management, developed by the multidisciplinary team and facilitated by street outreach workers. Intake data was gathered for each referred individual by the referring agent (i.e. their probation officer) and sent to the study personnel. A baseline survey was attempted for each individual shortly after referral; a follow-up survey was attempted roughly 10 months after referral. Judicial data for each referred individual was gathered from official sources from the 5 years prior to referral and for an 18-month period after referral.

Study Purpose View help for Study Purpose
The purpose of this study was to gather and analyze data to evaluate the effectiveness of the Gang Reduction Initiative in Denver (GRID), specifically to measure the effects of a MDT (multi-disciplinary team-based) approach, in promoting disengagement from gangs and desistance from crime.
Study Design View help for Study Design
A randomized control trial was used to measure the impact of the study. The treatment group consisted of young people randomly assigned to the GRID program, who received individualized and coordinated case management facilitated by a street outreach worker. The control group did not receive the same individualized service, but was referred to other community-based organizations that serve gang-involved populations.
To measure the effects of the intervention, the study team conducted a baseline interview at the beginning of the study and a follow up interview after nine months.
