title: Leaving Gangs and Desisting From Crime Using a Multidisciplinary Team Approach: A Randomized Control Trial Evaluation of the Gang Reduction Initiative of Denver (GRID), Colorado, 2014-2022
title: Version 1

description: 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.
description: 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.
description: 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.
description: Survey data includes demographics, employment, romantic relationships, family, health, police legitimacy and procedural justice, relationship with GRID outreach worker, social bonds, street code beliefs, gang embeddedness, gang membership, gang leaving, social schematic theory (including cynical view of others, low commitment to social conventions, and immediate gratification), substance use, law encounters, self report offending, self report victimization, orientation toward the future, exposure to violence (including suicidal ideation), identity, self control, masculinity, and a survey truthfulness scale. 
Intake data includes various measures relating to gang involvement, criminal history, school enrollment, employment, and demographics. Judicial data includes offending for felony, person, property, drug, and other crimes, in terms of arrests, filings, convictions, and incarcerations.
description: Response Rates: The response rate for the Baseline Survey was 66.4%; the response rate for the Follow-up Survey was 67.4%. 
Note: All people in the study were targeted for a follow-up survey regardless of whether they did the baseline survey. For intake and judicial data, there is data for 100% of the participants.
description: Presence of Common Scales: Several Likert-type scales were used.
description: All people in the study's universe were sampled (adolescents age 13+ and adults in Denver, CO, referred to a specific gang intervention program between June 2019-June 2021), with some exceptions imposed by the program itself.
