Experimental Details
Interventions
Intervention(s)
This trial studies the impact of a public summer jobs program in reducing violence. The 2013 One Summer Plus (OSP) program in Chicago offers 6 weeks of part-time summer employment at Illinois’ minimum wage ($8.25/hour). Local community organizations place youth in for-profit, nonprofit and government jobs (for example, clerks at a grocery store, summer camp counselors, workers in a community garden, or office assistants for an alderman). Youth are assigned job mentors—adults who help them learn to be successful employees and to navigate barriers to employment—at a ratio of about 10 to 1. All youth in the treatment group are also offered social-emotional learning (SEL) programming based on cognitive behavioral therapy principles, aimed at teaching youth to understand and manage the aspects of their thoughts, emotions, and behavior that might interfere with employment. Control youth are excluded from the program but are free to pursue other employment opportunities of their own volition.

Outcomes
Outcomes (end points)
Arrests for violent, property, drug, and other crime; provider and non-provider employment; and persistence in school.
Outcomes (explanation)
Primary outcome data include Illinois Statement Police arrest records covering both juveniles and adults, Illinois Department of Employment Security Unemployment Insurance records, and Chicago Public School records.
Experimental Design
Experimental Design
Male applicants were randomly selected for the treatment group from two applicants pools. The first pool of applicants (n = 2,127) was referred directly from the criminal justice system (from probation officers, juvenile detention or prison, or a center to serve justice-involved youth). No one was required to apply, but adults in the justice agencies invited youth who they judged to be work-ready to fill out applications. The rest of the applicants (n = 3,089) had applied to Chicago's broader summer programming; those who were ages 16-20, lived in one of the 30 highest-violence community areas, and included a social security number on their application were entered into the lottery.

Data come from matching study youth to various administrative data sources. Program participation is from provider-tracked attendance records. Student-level administrative records from the Chicago Public Schools capture pre- and post program academic outcomes. Demographic information on applicants’ neighborhoods comes from matching the Census tract of youths’ home addresses to data from the American Community Survey. The main outcome measures are from individual-level Illinois State Police arrest records covering both juveniles and adults.
