Antisocial personality disorder (APD) is a serious public and mental health concern. Understanding how well conduct disorder (CD) and other mental disorders predict the development of APD among youth involved in the juvenile justice system is critical for prevention. This study used a stratified random sample of 1112 detained youth to examine the development of APD at a three-year followup interview. Nearly one fifth of male juvenile detainees later developed APD; approximately one quarter of male juvenile detainees with CD at baseline later developed APD. Significantly more males than females developed APD; no differences were found by race/ethnicity. Having five or more symptoms of CD, dysthymia, alcohol use disorder, or generalized anxiety disorder was significantly associated with developing modified APD (M-APD; APD without the CD requirement). Some disorders were strong predictors of APD; however, none were adequate screeners for identifying which detainees would later develop M-APD. The findings of this study have implications for interventions and further research in developmental psychopathology. Keywords conduct disorder; antisocial personality disorder; mental disorder; detained youth; longitudinal Persistent antisocial behavior places a heavy burden on the community, the justice system, and the public health system (Miller, Cohen, & Wiersema, 1996). Adults with antisocial personality disorder (APD) are likely to experience a range of problematic behaviors and outcomes: criminal and violent behavior, substance use, early death, divorce, unemployment, and homelessness (Black, Baumgard, Bell, & Kao, 1996;Hodgins & Cote, 1993;Jainchill, Hawke, & Yagelka, 2000;Robins, Tipp, & Przybeck, 1991;Westermeyer & Thuras, 2005).Corresponding Author: Jason J.

Considering the high social and financial costs associated with APD, identifying youth at risk for this disorder is critical for prevention (Loeber, Green, & Lahey, 2003;Offord, 2000).
NIH Public AccessAmong many of the factors hypothesized to affect the development of APD are mental disorders in childhood and adolescence. Conduct disorder (CD) in childhood and adolescence is the factor most often associated with the development of APD (Abramowitz, Kosson, & Seiden...
