Researchers interviewed nearly 2,000 youths up to five years after they were released from juvenile detention to assess their mental health. More than 45 percent of males and nearly 30 percent of females had one or more psychiatric disorders, much higher than the general population. Substance use disorders were the most prevalent (most common in non-Hispanic whites.) Many kids don’t get treatment due to lack of services, perpetuating the revolving door between the community and corrections.
