Background Studies of pediatric conduct disorder (CD) have described frontal and temporal lobe structural abnormalities that parallel findings in antisocial adults. The purpose of this study was to examine previously unexplored cortical thickness and folding as markers for brain abnormalities in “pure CD”-diagnosed adolescents. Based on current fronto-temporal theories, we hypothesized that CD youth would have thinner cortex or less cortical folding in temporal and frontal lobes than control subjects. Methods We obtained T1-weighted brain structure images from n=24 control and n=19 CD participants aged 12–18 years, matched by overall gender and age. We measured group differences in cortical thickness and local gyrification index (regional cortical folding measure) using surface-based morphometry with clusterwise correction for multiple comparisons. Results CD participants, when compared with controls, showed both reduced cortical thickness and folding. Thinner cortex was located primarily in posterior brain regions, including left superior temporal and parietal lobes, temporoparietal junction and paracentral lobule, right superior temporal and parietal lobes, temporoparietal junction and precuneus. Folding deficits were located mainly in anterior brain regions and included left insula, ventro- and dorsomedial prefrontal, anterior cingulate and orbitofrontal cortices, temporal lobe, right superior frontal and parietal lobes and paracentral lobule. Conclusions Our findings generally agree with previous CD volumetric studies, but here show the unique contributions of cortical thickness and folding to gray matter reductions in pure CD in different brain regions.

Emerging research suggests that antisocial behavior in youth is linked to abnormal brain white matter microstructure, but the extent of such anatomical connectivity abnormalities remain largely untested because previous Conduct Disorder (CD) studies typically have selectively focused on specific frontotemporal tracts. This study aimed to replicate and extend previous frontotemporal diffusion tensor imaging (DTI) findings to determine whether noncomorbid CD adolescents have white matter microstructural abnormalities in major white matter tracts across the whole brain. Seventeen CD-diagnosed adolescents recruited from the community were compared to a group of 24 non-CD youth which did not differ in average age (12–18) or gender proportion. Tract-based spatial statistics (TBSS) fractional anisotropy (FA), axial diffusivity (AD), and radial diffusivity (RD) measurements were compared between groups using FSL nonparametric two-sample t test, clusterwise whole-brain corrected, p<.05. CD FA and AD deficits were widespread, but unrelated to gender, verbal ability, or CD age of onset. CD adolescents had significantly lower FA and AD values in frontal lobe and temporal lobe regions, including frontal lobe anterior/superior corona radiata, and inferior longitudinal and fronto-occpital fasciculi passing through the temporal lobe. The magnitude of several CD FA deficits was associated with number of CD symptoms. Because AD, but not RD, differed between study groups, abnormalities of axonal microstructure in CD rather than myelination are suggested. This study provides evidence that adolescent antisocial disorder is linked to abnormal white matter microstructure in more than just the uncinate fasciulcus as identified in previous DTI studies, or frontotemporal brain structures as suggested by functional neuroimaging studies. Instead, neurobiological risk specific to antisociality in adolescence is linked to microstructural abnormality in numerous long-range white matter connections among many diverse different brain regions.

Application of the Risk-Needs-Responsivity (RNR) model in adult correctional research and practice is well developed, but remains underway in the juvenile justice system. The RNR model may facilitate a shift from punitive practices in the juvenile justice system toward individualized assessment and treatment of youth fostering rehabilitation and reintegration. This article reviews the history of the RNR model in adult correctional settings, its theoretical application to the juvenile justice system, and available tools and literature utilizing RNR principles in juvenile justice settings. Criticisms of applying the RNR model to the juvenile justice system and future research directions are addressed.

Youth involved in the justice system meet criteria for psychiatric disorders at much higher rates than youth in the general population and a large body of research has established a relationship between mental health problems and delinquency or recidivism. However, only limited research has examined the relationship between specific types of psychopathology and specific patterns or types of delinquency for justice-involved youth and only a single study has explored the relationship between psychopathology and delinquency among youth with psychiatric diagnoses receiving mental health treatment. We examined the relationship between severity of offending and internalizing and externalizing symptoms among court-involved, non-incarcerated youth referred for mental health treatment. Over half of youth and over two-thirds of parents reported youth symptomatology at the 93 rd percentile or above for internalizing symptoms, externalizing symptoms, or both. We found that youth engaged in serious or violent delinquency are more likely to have externalizing problems but that internalizing symptoms were equally high across youth committing minor, moderate, and serious delinquent acts. Findings from this study support the need for future research exploring the nuances of relationships between psychiatric disorder and patterns of delinquency, which can provide helpful information to justice system stakeholders in identifying youth needs.

False confessions represent a significant problem for the criminal and juvenile justice systems and juveniles may be at particular risk for falsely confessing. In part, this risk may be due to juveniles’ greater likelihood of waiving Miranda rights and, consequently, undergoing interrogation, as well as their heightened suggestibility and greater susceptibility to and compliance with authority figures compared to adults. With data from 260 participants in correctional facilities, this study compared juveniles’ (n = 168) and adults’ (n = 92) self-reported likelihood of false confessions. Younger juveniles reported significantly greater false confession propensity than did adults, especially in response to directive interrogation techniques. Older juveniles did not differ significantly from adults in their self-reported likelihood of false confession. Miranda rights comprehension mediated the relationship between age and false confession likelihood. These findings suggest the need for greater protections of younger juveniles during interrogations.
