Co-Occurring Mental Health and Substance Use Disorders Among Recently Booked Arrestees

This special topic report examines the prevalence and characteristics of co-occurring substance abuse and mental health problems among adult arrestees in Maricopa County. The findings suggest that more than 28 percent of adult arrestees in Maricopa County are at risk for a co-occurring disorder, and they face significantly greater difficulties across a number of critical factors, including incarceration, homelessness, and victimization. Understanding the prevalence and particular characteristics of the dual-diagnosed arrestee population in Maricopa County is an important part of assessing demands on behavioral health and substance use treatment resources. Additionally, examining some of the current defining characteristics of this population relative to arrestees not dually diagnosed can serve as an indicator of future demand.
