Objective: Describe the rates of suicidal ideation, self-injury, and suicide among detained youth as well as risk factors and preventive measures that have been attempted. Method: Literature searches in PubMed, PsycINFO, and the Social Science Citation Index were undertaken to identify published studies written in English. Governmental data was also included from English-speaking nations. Results: The adjusted risk of suicide was 3 to 18 times higher than age-matched controls. The prevalence of lifetime suicidal ideation ranged from 16.9% to 59% while lifetime self-injury ranged from 6.2% to 44%. Affective disorders, borderline personality traits, substance use disorders, impulse control disorders, and anxiety disorders were associated with suicidal thoughts and self-injury. Screening for suicidal ideation upon entry was associated with a decreased rate of suicide. Conclusions: All youth should be screened upon admission. Identified co-morbid disorders should also be treated.
