Adolescent psychopathy features: 6-year temporal stability and the prediction of externalizing symptoms during the transition to adulthood.

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.

Trait affectivity and non-referred adolescent conduct problems.

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.

The relation between salivary cortisol, callous-unemotional traits, and conduct problems in an adolescent non-referred sample.

Background: Previous research has suggested that adult psychopathic behavior and child callous-unemotional (CU) traits are uniquely related to low emotional reactivity. Salivary cortisol is a promising biological measure of emotional reactivity that has been relatively overlooked in research on CU traits and antisocial behavior. The current study examined for gender differences in the relation between resting salivary cortisol levels and CU traits in a non-referred adolescent sample.
