Unpacking the Impacts of a Youth Behavioral Health Intervention: Experimental Evidence from Chicago

Nour Abdul-Razzak Kelly Hallberg

This working paper details results from a study of Choose to Change® (C2C®), a trauma-informed cognitive behavioral therapy and intensive mentoring program developed by nonprofits Brightpoint and Youth Advocate Programs, Inc. (YAP).

Abstract

Racial disparities in violence exposure and criminal justice contact are a subject of growing policy and public concern. We conduct a large-scale, randomized controlled trial of a six-month behavioral health intervention combining intensive mentoring and group therapy designed to reduce criminal justice and violence involvement among Black and Latinx youth in Chicago. Over 24 months, youth offered the program experienced an 18 percent reduction in the probability of any arrest and a 23 percent reduction in the probability of a violent-crime arrest. These statistically significant impacts, with smaller magnitudes, continue to persist up to 3 years post randomization. To better understand the behavior change we observe given an arrest is a proxy for criminal behavior, we create a supervised machine learning algorithm from arrest narratives that determines if an arrest was initiated more or less at the discretion of police. We find that the program’s impacts are concentrated in arrests where officers have less discretion in initiating contact, while having little impact on more discretionary contact arrests (e.g. a young person exhibiting “suspicious” behavior). This analysis suggests the effects of the program are being driven by a reduction in youth offending behavior rather than by avoiding police contact.
