If you work with justice-involved juvenile, you need to read this bulletin. "Incarcerated youth die by suicide at a rate two to three times higher than that of youth in the general population. In this bulletin, the authors examine suicidal thoughts and behaviors among 1,829 youth ages 10 to 18 in the Northwestern Juvenile Project—a longitudinal study of youth detained at the Cook County Juvenile Temporary Detention Center in Chicago, IL (p. 1). Findings are presented for: hopelessness; thoughts about death and dying; thoughts about suicide; suicide plan; telling someone about suicidal thoughts; suicide attempts; and psychiatric disorders that may increase the odds of suicide attempts. Additional discussion concerns demographic characteristics and suicide risk, and psychiatric disorders and suicide risk. Based on the results, detention facilities need to systematically screen juveniles for suicide risk within 24 hours of arrival if not sooner, and increase the availability of psychiatric services.
