Do black and white youths differ in levels of psychopathic traits? A meta-analysis of the psychopathy checklist measures.

Putative ethnic group differences in various forms of psychopathology may have important theoretical, clinical, and policy implications. Recently, it has been argued that individuals of African descent are more likely to be psychopathic than those of European descent (R. Lynn, 2002).

The influence of psychosocial maturity on male juvenile offenders' comprehension and understanding of the Miranda warning.

Self-report measures of psychosocial maturity and screening measures of achievement and intelligence (Wechsler Abbreviated Scale of Intelligence; WASI) were used to investigate the influence of psychosocial maturity on male juvenile offenders' comprehension and appreciation of the Miranda warning (Grisso's Instruments for Assessing Understanding and Appreciation of Miranda Rights; GUAM). A sample of 67 male juvenile offenders, placed in a short-term detention facility or juvenile boot camp facility, participated in the study. Demographic differences revealed that youths in short-term detention were approximately one year older than boot camp youths.

Psychopathy, conduct disorder, and stigma: does diagnostic labeling influence juvenile probation officer recommendations?

This study investigated the potential influence of labeling a juvenile as psychopathic. Juvenile probation officers (JPOs; N = 260) rendered hypothetical recommendations based on eight mock psychological evaluations. The evaluations varied the presence of two diagnostic criteria (antisocial behavioral history and psychopathic personality traits) and diagnostic labels (psychopathy, conduct disorder, no diagnosis) in order to distinguish criterion effects from labeling effects.
