Incarcerated youth with personality disorders: prevalence, comorbidity and convergent validity.

Objective: The aims of this study were to examine the prevalence and comorbidities of personality disorders among incarcerated juveniles and to investigate the validity of these results.

Method: A sample of 790 incarcerated youth (650 boys and 140 girls; mean age = 16.8 years) completed an assessment of Axis II diagnoses (Structured Interview for DSM-IV Personality).

Psychopathology, trauma and delinquency: subtypes of aggression and their relevance for understanding young offenders.

Objective: To examine the implications of an ontology of aggressive behavior which divides aggression into reactive, affective, defensive, impulsive (RADI) or "emotionally hot"; and planned, instrumental, predatory (PIP) or "emotionally cold." Recent epidemiological, criminological, clinical and neuroscience studies converge to support a connection between emotional and trauma related psychopathology and disturbances in the emotions, self-regulation and aggressive behavior which has important implications for diagnosis and treatment, especially for delinquent populations.

Method: Selective review of preclinical and clinical studies in normal, clinical and delinquent populations.

Prevalence differences of psychiatric disorders among youth after nine months or more of incarceration by race/ethnicity and age.

Despite high rates of psychiatric morbidity among young offenders, few studies look closely at prevalence rates in terms of race/ethnicity or developmental stage. Seven hundred and ninety (790) incarcerated young people with a mean age of 18+/-1.2 years were examined.

Prevalence of and gender differences in psychiatric disorders among juvenile delinquents incarcerated for nine months.

Objective: This study examined prevalence rates of psychiatric disorders among young offenders after they were incarcerated for nine months.

Methods: A total of 790 youths were surveyed, including a significant proportion of females (N=140, 18%), nine months after incarceration. The Structured Clinical Interview for DSM-IV with portions of the Diagnostic Interview for Children and Adolescents and the Structured Interview for DSM-IV Personality were used.

Ethnic variation of self-reported psychopathology among incarcerated youth.

Research on ethnic minority populations has shown them to be undertreated, underdiagnosed and perceived as more psychopathological in comparison to the Caucasian population. This study aimed to assess ethnic variation of self-perceived psychopathology in a population of incarcerated youths. The Youth Self-Report (YSR) was completed by 5964 incarcerated adolescents (95% male; mean age = 16.
