The current findings build upon recent research in suggesting that low cortisol may be a biological marker for male CU traits.

This study investigated the 6-year stability and predictive validity of adolescent psychopathy features during the transition to young adulthood. It represents one of the longest outcome studies of youth psychopathy to date, and therefore addresses a primary criticism of the research area (i.e., lack of demonstrated associations between child and adult psychopathy features). Recruited participants were 475 males enrolled in the Minnesota Twin and Family Study who had completed a research-based measure of psychopathy features consisting of separate emotional detachment (or affective) and antisocial tendencies (or behavioral) subscales. These psychopathy features and various externalizing symptoms (i.e., conduct problems, impulsivity, and substance use disorder) were assessed through rating scales and structured diagnostic interview at an intake assessment (ages 16-18) and 6-year follow-up. Consistent with prediction, adolescent psychopathy features displayed moderate stability across the transition from adolescence to adulthood [intraclass correlation coefficients (ICCs) = 0.40-0.41]. The antisocial tendencies subscale was uniquely related to most externalizing symptoms both in adolescence and in adulthood, whereas the emotional detachment subscale showed appropriate discriminant validity in its lack of association with externalizing symptoms. These findings suggest that psychopathy features are relatively stable from adolescence to adulthood and provide possible insights into the development and maintenance of externalizing difficulties during the adult transition.

This article reviews the interpersonal-psychological theory of attempted and completed suicide and describes its applications in suicide risk assessment, crisis intervention, and skills-based psychotherapies. Three components are necessary, but not sufficient, for an individual to die by suicide: (1) the acquired capability to enact lethal self-injury, (2) a sense that one is a burden on others, and (3) the sense that one does not belong to a valued social group. We suggest that therapeutic interventions should focus on ascertaining the presence of these components and work to amend the cognitive distortions, negative interpersonal response styles, and ineffective coping behaviors that serve to maintain suicidal urges.

The Massachusetts Youth Screening Instrument-Version 2 (MAYSI-2) is a brief triage tool designed to pinpoint youth in the juvenile justice system at risk for mental health-related difficulties. The current study investigated the relation between the MAYSI-2 and institutional maladjustment at a residential treatment facility specializing in the rehabilitation of severe male juvenile offenders. Institutional maladjustment data were collected during the first 90 days of commitment for 104 male juvenile offenders who also completed the MAYSI-2 during orientation to the facility. The Angry-Irritable subscale of the MAYSI-2 uniquely predicted severe rule violations and intensive supervision placement. However, hit rate analyses revealed a high level of false negatives for the published subscale cut scores. Implications of these and related findings are discussed.

This study examined for profiles of positive trait affectivity (PA) and negative trait affectivity (NA) associated with adolescent conduct problems. Prior trait affectivity research has been relatively biased toward the assessment of adults and internalizing symptomatology. Consistent with recent developmental modeling of antisocial behavior, this study proposed that conduct problems are uniquely associated with 2 PA-NA profiles (i.e., high PA-high NA and low PA-low NA). A non-referred sample of 109 adolescents ages 12 to 19 was recruited to assess the independent relations between rating scale measures of the PA-NA dimensions and conduct problems, controlling for related internalizing (anxiety and depression) and externalizing (hyperactivity-impulsivity) symptomatology. The results generally confirmed the proposed interaction between the PA-NA dimensions in the prediction of adolescent conduct problems.
