OBJECTIVE: Although studies reveal substantial mental health treatment needs among youths in the juvenile justice system, far less is known about young offenders transferred to adult criminal court. This statewide study examined the mental health needs of young offenders who committed serious crimes and were transferred to adult court and subsequently incarcerated in a prison for adults. METHODS: Sixty-four boys aged 16 and 17 years who were incarcerated in the Texas adult correctional system completed the Massachusetts Youth Screening Instrument-Version 2 (MAYSI-2), a mental health screening measure widely used in the juvenile justice system. Scores from the youths in adult prison were compared with those of a matched sample of youths in juvenile correctional facilities, drawn from the MAYSI-2 normative data. RESULTS: Youths in adult prison reported substantial symptoms of mental health problems. Most youths surveyed (51%) scored above the highest clinical cutoff (the "warning" range) on at least one MAYSI-2 subscale. For every clinical subscale except suicide ideation, the majority of youths (54% to 70%, depending on the subscale) scored above the "caution" range. Juveniles in adult prison reported higher rates of symptoms than did those in juvenile correctional facilities (effect sizes ranged from d=.18 to d=.65, depending on the subscale). CONCLUSIONS: Although the mental health needs of youths in the juvenile justice system are well documented, this study reveals that mental health treatment needs appear to be even more pronounced in the small subgroup of youths transferred to the adult criminal justice system and incarcerated in adult prison.

BACKGROUND: Recently, researchers have sought to measure psychopathy-like features among youth in hopes of identifying children who may be progressing toward a particularly destructive form of adult pathology. However, it remains unclear whether psychopathy-like personality features among youth are best conceptualized as dimensional (distributed along a continuum) or taxonic (such that youth with psychopathic personality characteristics are qualitatively distinct from non-psychopathic youth). METHODS: This study applied taxometric analyses (MAMBAC, MAXEIG, and L-Mode) to scores from two primary measures of youth psychopathy features: the Psychopathy Checklist: Youth Version (N = 757) and the self-report Antisocial Process Screening Device (N = 489) among delinquent boys. RESULTS: All analyses supported a dimensional structure, indicating that psychopathy features among youth are best understood as existing along a continuum. CONCLUSIONS: Although youth clearly vary in the degree to which they manifest psychopathy-like personality traits, there is no natural, discrete class of young 'psychopaths.' This finding has implications for developmental theory, treatment, assessment strategies, research, and clinical/forensic practice.
