Rearrest is associated with heightened callous-unemotional traits: No moderating effect of maternal relationship quality.

OBJECTIVE: The presence of callous-unemotional (CU) traits in adolescence predisposes youth to negative behavioral and social outcomes and may be particularly damaging to youth involved in the justice system. Whereas research has shown that CU traits predict later arrest, it remains unknown whether rearrest predicts changes in CU traits and whether these associations may be modified by maternal relationship quality. The present study assessed whether being rearrested predicted changes in CU traits and whether these associations varied by maternal warmth and maternal hostility. HYPOTHESES: We hypothesized that self-reported CU traits would increase at data collection time points following rearrest. Further, we hypothesized that maternal warmth would buffer the negative effects of rearrest, whereas maternal hostility would not have a significant moderating effect on the associations. METHOD: Hypotheses were tested using a large, multisite longitudinal data set of 1,216 justice-involved male youth (Mage = 15.82 years at baseline; 47% Latino, 38% Black/African American, 15% White). Data from a series of nine interviews (across a 7-year period) were used to determine associations between rearrest at one-time point and CU traits at the subsequent time point. RESULTS: Rearrest is associated with a significant increase in CU traits. However, these associations are not moderated by either maternal warmth or maternal hostility. CONCLUSIONS: Rearrest predicts increases in a known risk factor for healthy socioemotional development among justice-involved youths (CU traits). Moreover, the way rearrest is associated with CU traits does not change depending on maternal warmth; rearrest is associated with increases in CU traits irrespective of the quality of a youth's relationship with their mother.

Early life adversity is associated with attenuated testosterone reactivity to acute stress among adolescents.

Understanding how testosterone responds to stress or challenge may be integral to uncovering biological pathways to potentially harmful behaviors like aggression. Yet, studies investigating patterns of testosterone reactivity under stress within adolescent populations are limited. Among those conducted, even fewer have investigated environmental factors which may shape such patterns. Exposure to early life adversity (ELA) has been shown to influence other biological markers of stress reactivity, though how it may be associated with alterations in testosterone reactivity remains underexplored. The current study addresses these gaps by examining salivary testosterone concentrations across the administration of a Trier Social Stress Test for Children in a sample of 87 adolescents (46.4% female, Mage = 13.91 years, SDage = 1.57). The current study tested two central hypotheses: (1) that testosterone would rise in response to a standardized laboratory stressor, and (2) that greater ELA would be associated with higher baseline (or, pre-stress) testosterone scores and a dampened testosterone response to stress. Adolescents in the current sample showed a robust increase in testosterone following administration of the TSST-C, supporting the limited previous findings which indicate testosterone does mount an acute stress response in adolescents. Contrary to hypotheses, ELA was not associated with significant elevations in baseline testosterone scores. However, ELA was associated with dampened testosterone reactivity, even after controlling for important demographic and biological factors. Methodological implications, including considerations for researchers aiming to capture an acute testosterone response, as well as how our understanding of ELA's role in adolescent biological functioning is extended by our findings regarding testosterone, are discussed.

Examining the relation among callous-unemotional traits and cortisol, alpha-amylase, and testosterone reactivity in legal system involved young men.

Elevated callous-unemotional (CU) traits (e.g., lack of empathy, deficient guilt/remorse, and shallow affect) are associated with increased antisociality and distinct patterns of cognitive and emotional functioning. Previous investigations have suggested that deficits in physiological stress responses may underlie these associations, yet few studies simultaneously examine the multiple physiological systems responsible for mounting a stress response. To clarify how individuals with and without elevated CU traits respond to acute stress, the current study examined the association between CU traits and hormones released by three systems: cortisol from the hypothalamic-pituitary-adrenal (HPA) axis, alpha-amylase from the sympathetic nervous system (SNS), and testosterone from hypothalamic-pituitary-gonadal (HPG) axis. Specifically, we used fixed effect regression modeling to examine within-individual changes in each biomarker across the administration of a standardized laboratory stressor (Trier Social Stress Test) in a sample of 55 justice-involved young men (Mage= 22.84). Results indicated significant within-individual changes in cortisol, alpha-amylase, and testosterone following the stressor among those with low or average CU traits. However, those with high levels of CU exhibited no significant changes in their cortisol and testosterone levels. Furthermore, individuals with high CU traits exhibit an asymmetric stress response, such that alpha-amylase and testosterone levels were not associated with changes in cortisol levels. In sum, elevated CU traits were associated with blunted cortisol and testosterone reactivity and asymmetric response to stress. Additional work is needed to determine the behavioral and treatment implications of this distinct stress response.
