RHR was measured using a wristband, and CU traits and delinquency history were assessed using self-reported questionnaires. Moderation analysis was performed to understand how the combination between RHR and CU is associated to offending.Results: CU traits were associated with offending at all ages. The interactions between RHR and CU traits were significantly related to the likelihood of offending in the early and the late adolescent. The highest likelihood of offending is related to high CU traits combined with low RHR in early adolescents and with high RHR in late adolescents.Conclusions: These findings provide further insight in the relationship between psychopathic traits and bio-physiological maturation in explaining juvenile delinquency.

Consequently, it is not well known if the psychopathy construct adds to the prediction of recidivism over other risk factors, such as conduct disorder and past criminality. To address this research gap, the current study examined data from 302 detained girls (M age = 16.2). Psychopathy total and component (i.e., narcissism, callous-unemotional, and impulsivity) scores were derived from the self-report version of the Antisocial Process Screening Device (APSD). Latent profile analysis was used to identify girls with high scores on the three com-ponents (tentatively labeled 'putative psychopathic personality'). Five youth recidivism outcomes were measured (i.e., violent, serious non-violent, drug, total, and versatile), based on arrest charges that occurred before girls were 18 years of age. With a few exceptions, neither the ASPD total nor the APSD component scores contributed to the prediction of the recidivism outcomes. Girls with a putative psychopathic personality also were not at increased risk for recidivism. Findings overall suggest that the psychopathy construct should not be used for risk assessment purposes among detained girls, at least not when assessed via the self-report version of the APSD.
