Abstract: The current study compared the psychometric properties and incremental validity of the callous-unemotional (CU) traits dimensions from four self-report measures of youth psychopathic traits, including the Antisocial Process Screening Device Self-Report version (APSD-SR), the Youth Psychopathic Traits Inventory (YPI), Youth Psychopathic Traits Inventory–Short version (YPI-S), and the Inventory of Callous-Unemotional Traits (ICU) among a sample of male youth incarcerated in Portuguese detention centers (N = 221). Across these measures, estimates of reliability and internal consistency were generally good; however, the correlations between measures ranged from very low to high suggesting moderate convergent validity. With regard to incremental validity, the Callousness dimension of the ICU was the best predictor of aggression, conduct disorder, and crime seriousness, whereas the Uncaring dimension of the ICU was the best predictor of age of crime onset. The current findings have important implications regarding the assessment of CU traits.

Abstract: It is a criminological fact that females commit fewer delinquent acts than their male counterparts. This “gender gap” has long been recognized but specific questions concerning similarities or differences in the development, persistence, and desistence of antisocial behavior among females and males remain underinvestigated. Two prominent theoretical models, Moffitt’s developmental taxonomy and Silverthorn and Frick’s delayed-onset pathway, make distinct predictions about the composition of female offenders and the nature of their offending. The current study tests these explanations using longitudinal data from the Pathways to Desistance Study, a large sample of serious juvenile offenders followed for 7 years into early adulthood. Results from a series of negative binominal regressions reveal stronger support for Moffitt rather than Silverthorn and Frick in that findings showed two groups of female offenders. Directions for future research are highlighted.
