The reciprocal relationships between moral disengagement and antisocial behavior from ages 16 to 23.

Moral disengagement (MD) has been consistently associated with antisocial behavior (ASB) in prior research. Limited research tested the directionality of the bivariate relationship, and most studies focused only on the direction of MD predicting ASB, even though ASB could also influence MD based on the literature on attribution and behavioral influence on attitude. Moreover, the few studies testing reciprocal associations rarely controlled for stable individual differences and did not explicitly examine the age effect to allow for a clear developmental inference. We analyzed age-based self-report antisocial behavior and moral disengagement data across ages 16-23 from 1,349 juvenile offenders (86.43% male; 20.31% White, 41.29% Black, 33.65% Hispanic) in the Pathways to Desistance Project using a random intercept cross-lagged panel model. Controlling for stable individual differences in MD and ASB and their associations along with the autoregressive effects, there was a reciprocal relationship between MD and ASB from ages 16 to 18. However, from ages 19 to 21, only ASB significantly predicted MD in the following year. There was no significant cross-lagged effect from ages 21 to 23. Our findings highlight the dynamic relationship between MD and ASB from ages 16 to 23. Youth between 16 and 18 years old may be more pliable to change with treatment/intervention due to the two-way traffic of cognition and behavior, but we also caution against treatment efforts with a heavy focus on proactive criminal thinking involving moral disengagement to reduce offending behavior beyond age 18.

Callous-unemotional traits and pre-ejection period in response to reward.

Callous-unemotional (CU) traits have important utility in distinguishing individuals exhibiting more severe and persistent antisocial behavior, and our understanding of reward processing and CU traits contributes to behavioral modification. However, research on CU traits often investigated reward alongside punishment and examined solely on average reward reactivity, neglecting the reward response pattern over time such as habituation. This study assessed individuals' pre-ejection period (PEP), a sympathetic nervous system cardiac-linked biomarker with specificity to reward, during a simple reward task to investigate the association between CU traits and both average reward reactivity and reward response pattern over time (captured as responding trajectory). A heterogeneous sample of 126 adult males was recruited from a major metropolitan area in the US. Participants reported their CU traits using the Inventory of Callous-Unemotional Traits and completed a simple reward task while impedance cardiography and electrocardiogram were recorded to derive PEP. The results revealed no significant association between average PEP reward reactivity and CU traits. However, CU traits predicted both linear and quadratic slopes of the PEP reactivity trajectory: individuals with higher CU traits had slower habituation initially, followed by a rapid habituation in later blocks. Findings highlight the importance of modeling the trajectory of PEP reward response when studying CU traits. We discussed the implications of individuals with high CU traits having the responding pattern of slower initial habituation followed by rapid habituation to reward and the possible mechanisms.

Unique and interactive effects of threat and deprivation on latent trait cortisol among emerging adults.

Though considerable work supports the Dimensional Model of Adversity and Psychopathology, prior research has not tested whether the dimensions-threat (e.g., abuse) and deprivation (e.g., neglect)-are uniquely related to salivary trait indicators of hypothalamic pituitary adrenal (HPA) axis activity. We examined the unique and interactive effects of threat and deprivation on latent trait cortisol (LTC)-and whether these effects were modified by co-occurring adversities. Emerging adults (n = 90; Mage = 19.36 years; 99.88% cisgender women) provided salivary cortisol samples four times a day (waking, 30 min and 45 min postwaking, bedtime) over three 3-day measurement waves over 13 weeks. Contextual life stress interviews assessed early adversity. Though the effects varied according to the conceptualization of early adversity, overall, threat-but not deprivation, nor other co-occurring adversities-was uniquely associated with the across-wave LTC. Specifically, the incidence and frequency of threat were each negatively related to the across-wave LTC. Threat severity was also associated with the across-wave LTC, but only among those with no deprivation. Finally, the effects of threat were modified by other co-occurring adversities. Findings suggest that threat has unique implications for individual differences in HPA axis activity among emerging adults, and that co-occurring adversities modify such effects.

PEP reward reactivity moderates the effects of RSA reactivity on antisocial behavior and substance use.

Integrating Polyvagal Theory and Reinforcement Sensitivity Theory (RST), we examined pre-ejection period (PEP) reward reactivity, which was suggested to index trait impulsivity, as a moderator between respiratory sinus arrhythmia (RSA) reactivity and antisocial behavior (ASB), and substance use in an urban male, adult sample. To understand the inconsistent findings between RSA reactivity and externalizing problems, we proposed to study both negatively and positively valenced tasks for RSA reactivity and to include PEP reward reactivity as a moderator for the RSA-behavior link. Data were collected from an urban sample of 131 male adults (active offenders, demographic controls, and college students). ICG (impedance cardiography) and ECG (electrocardiogram) were recorded, computing PEP (sympathetic nervous system activity marker) and RSA (parasympathetic nervous system activity marker), while participants completed the modified Trier Social Stress Test and a simple reward task. Reactivity was calculated by subtracting the baseline from the task activity. Consistent with prior studies, more RSA withdrawal to stress and less PEP shortening to reward predicted the most ASB and substance use. Less RSA withdrawal to reward and more PEP shortening to reward predicted the most ASB and substance use. We incorporated autonomic space, RST, and Polyvagal Theory to discuss our findings, and specifically highlight how clarifying what each reactivity captures based on the task demand (e.g., presence of social threat, need for vagal-mediated social affiliative behavior) can illuminate our understanding of the result patterns.

Parentification Vulnerability, Reactivity, Resilience, and Thriving: A Mixed Methods Systematic Literature Review.

Parentification occurs when youth are forced to assume developmentally inappropriate parent- or adult-like roles and responsibilities. This review thoroughly examines current empirical research on parentification, its outcomes, and related mechanisms to outline patterns of findings and significant literature gaps. This review is timely in the large context of the COVID-19 pandemic, when pandemic-induced responsibilities and demands on youth, and the shifting family role may exacerbate parentification and its consequences. We used the 2020 updated Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) framework to identify 95 studies (13 qualitative, 81 quantitative, 1 mixed methods) meeting eligibility criteria. Representation from six continents highlights parentification as a global phenomenon. Using thematic analysis, we identified five themes from qualitative studies and five from quantitative studies. These were further integrated into four common themes: (1) some parentified youth experienced positive outcomes (e.g., positive coping), albeit constructs varied; (2) to mitigate additional trauma, youth employed various protective strategies; (3) common negative outcomes experienced by youth included internalizing behaviors, externalizing problems, and compromised physical health; and (4) youths' characteristics (e.g., rejection sensitivity, attachment style), perceived benefits, and supports influenced parentification outcomes. Future methodological and substantive directions are discussed.

Early adversity and depressive symptoms among early adolescent girls: the mediating role of exposure to recent interpersonal acute stress.

Early adversity confers risk for depression in part through its association with recent (i.e., proximal) acute stress. However, it remains unresolved whether: a) early adversity predicts increases in recent acute stress over time; b) all - or only certain types - of recent events mediate the relationship between early adversity and depression; and c) early adversity places individuals at greater risk for depression via greater exposure to independent (i.e., fateful) interpersonal events or via greater generation of dependent (i.e., partially self-initiated) interpersonal events (i.e., stress generation) or both. These questions were examined in a 3-wave longitudinal study of early adolescent girls (N = 125; M = 12.35 years [SD = .77]) with no history of diagnosable depression using contextual life stress and diagnostic interviews. Path analyses indicated that increases in past-year acute interpersonal, but not non-interpersonal, stress mediated the link between early adversity and depressive symptoms. The mediating role of interpersonal events was limited to independent ones, suggesting increases in interpersonal event exposure, not interpersonal stress generation, acted as a mediator. Finally, findings support prior evidence that early adversity may not directly predict future depressive symptoms. Implications for understanding the role of recent stress in the association between early adversity and adolescent depression are discussed.

Individual differences in latent trait cortisol (LTC): Implications for the onset and course of future depressive symptoms.

Research suggests that various indicators of hypothalamic pituitary adrenal (HPA) axis activity prospectively predict depression, but few studies have evaluated whether trait indicators of HPA axis activity are related to depression. Further, no prior study has examined links between trait cortisol and psychopathology using a trait indicator that captures HPA axis activity over multiple time points. Here we examined whether we could construct an across-wave latent trait cortisol (LTC) factor using cortisol samples collected over 13 weeks, and whether the across-wave LTC prospectively predicted new depressive symptom onsets and symptom duration. Emerging adults (n = 85; M age = 19.37 years) provided salivary cortisol samples four times a day (waking, 30 min and 45 min post-waking and bedtime) over three 3-day measurement waves separated by 6 weeks. Diagnostic interviews at 3 timepoints (baseline, 1- and 2.5 years post-baseline) assessed lifetime and current depressive symptoms. Results indicated that the across-wave LTC predicted new onsets of depressive symptoms and longer symptom duration. Follow-up tests revealed that the link between the across-wave LTC and new onsets was not significant after adjusting for past depressive symptoms. These findings suggest that an indicator of individual differences in HPA axis regulation has implications for depressive symptom onsets and course.

Stress Coping Strategies as Mediators: Toward a Better Understanding of Sexual, Substance, and Delinquent Behavior-Related Risk-Taking among Transition-Aged Youth.

Transitional aged youth (18-24) report increasing and peaking risk-taking (sexual, substance, and delinquent behavior). Stressful life events (SLE) are associated with these risk-taking behaviors. Little is known regarding what mediates these relationships. This study tests whether various coping strategies mediate the relationship between SLE and risky behavior in three domains among 18-24 year olds (N=126; M age = 21.3, SD = 1.9; 52% Black; 56% female). After adjusting for covariates and simultaneously modeling two stress variables, only stressful life events, but not perceived stress, was uniquely associated with risk-taking behaviors at moderate to high levels. Significant indirect effects of SLE via avoidance coping were found for illicit drug use both concurrently and prospectively and for risky sex concurrently. For participants reporting greater stressful life experiences, substance use and risky sex behaviors become greater as avoidance coping increases. Avoidance coping was a partial mediator for the concurrent relationship between stressful life events and substance use/risky sex, but a full mediator for the prospective relationship between stressful life event and substance use. None of the coping strategies mediate the relationship between stressful life events and delinquency. Prevention and intervention strategy implications for reducing avoidance coping and promoting alternative coping styles are discussed.

The association between cortisol-AA coordination in response to stress, negative urgency, and antisocial behavior in an urban adult sample.

Prior study has found that the interplay of the hypothalamic-pituitary-adrenal (HPA) axis and the autonomic nervous system (ANS) influences behavior problems in youth. Yet, little is known regarding this relationship in adults and traits related to the coordination of the stress systems. This study aims to extend the findings of a youth sample that the coordination between HPA and ANS, measured as cortisol and alpha-amylase (AA) respectively, was associated with antisocial behavior in adults. Additionally, this study tests whether cortisol-AA coordination was associated with a conceptually relevant trait, negative urgency. A heterogeneous sample of 124 adults (college students, active offenders, and demographically matched controls) was recruited from a southern city. Participants filled out instruments for negative urgency and antisocial behavior, completed a modified Trier Social Stress Test (mTSST), and provided four saliva samples before and after mTSST to assay for cortisol and AA. Results showed that cortisol-AA stress coordination was stronger among offenders than other groups. Cortisol-AA stress coordination was also positively associated with antisocial behavior and with negative urgency. This study found support for the interpretation that cortisol-AA stress coordination may indicate an overshooting ANS response at high emotional distress, and highlight the importance of the multisystem approach in gaining new insights into behavior research.

The Cognitive, Affective and Somatic Empathy Scales for Adults.

The Cognitive, Affective and Somatic Empathy Scales (CASES) assess three forms of empathy, each with subscales for positive and negative empathy. The present study extends this child instrument to adults and examines its factor structure and construct validity. A secondary aim is to investigate the under-researched area of positive empathy. Community samples totaling 2,604 adults completed the CASES for adults, together with scales assessing construct validity. Confirmatory factor analysis supported the three-factor cognitive-affective-somatic model and a two-factor positive-negative empathy model. Findings were replicated in a second independent sample. Internal reliabilities ranged from .80 to .92. Individuals with higher psychopathy and stimulation-seeking scores were less impaired in their empathic reactions to positive relative to negative valence events, suggesting that they are relatively capable of responding emotionally to rewarding events. Somatic empathy was most strongly associated with pleasure in affective touch and with female > male gender differences. While proactive aggression was associated with reduced cognitive and affective empathy, reactive aggression was associated with increased empathy. Findings provide initial support for the utility of CASES for assessing different forms of empathy and suggest that the balance between positive and negative empathy could provide new insights into psychological traits.

Reduced Electrodermal Fear Conditioning and Child Callous-Unemotional Traits.

Diminished fear conditioning is a well-replicated finding in adult psychopathy. In contrast, there is virtually no research on fear conditioning and callous-unemotional (CU) traits in children. This study aimed to fill in this knowledge gap using a sample of predominantly African American children. The sample comprised 446 community-recruited children (mean age = 11.93 years; 52% boys; 82% African Americans). Skin conductance was recorded during a fear conditioning task and a resting task. CU traits were assessed using the Antisocial Processes Screening Device completed by children and their parents, while aggression was measured with the Buss-Perry Aggression Questionnaire-Short Form. Self-report, but not parent-report CU traits were inversely associated with fear conditioning skin conductance response. CU traits from either report source were not associated with skin conductance responding to the aversive stimulus, or with resting skin conductance level. This is the first study documenting an association between CU traits in children and reduced electrodermal fear conditioning. Findings highlight the importance of conditioned negative emotional arousability in CU traits, and lend support to the developmental psychopathology hypothesis that CU traits may result from impaired conscience development. Electrodermal fear conditioning has the potential to be incorporated into treatment protocols for screening and evaluation purpose.

The cognitive, affective, and somatic empathy scales (CASES): Cross-cultural replication and specificity to different forms of aggression and victimization.

A psychometrically sound measure of empathy that captures its multifaceted nature is critical in furthering research on empathy. The only instrument that assesses three domains of empathy together with positive and negative valence empathy is the newly developed 30-item cognitive, affective, and somatic empathy scales (CASES). The current study examines the cross-culture generalizability of CASES in Hong Kong and explores links between empathy and different forms of aggression and peer victimization. A sample of 4,676 Hong Kong youth (62% male) completed CASES, alongside measures of reactive/proactive aggression and multidimensional peer victimization. A subsample of youth (n = 2,321-2,464) and their parents completed additional instruments for testing the validity of CASES. We replicated most of the concurrent, convergent, and discriminant validity findings in the original development of CASES. Proactive aggression was most strongly linked to affective empathy, whereas reactive aggression was most strongly linked to somatic empathy. Differential associations were revealed between subscales of CASES and forms of peer victimization. Findings provide cross-cultural generalizability for a brief self-report instrument that captures the multifaceted nature of empathy. The multifaceted nature of empathy is further supported by differential associations with forms of aggression and victimization.

The within-person coordination of HPA and ANS activity in stress response: Relation with behavior problems.

This study tests the within-person coordination of HPA and ANS activity in response to stress and examines for the first time the association between such coordination and behavior problems in minority urban children. Participants, ages 11-12 (N = 419; 50 % male; 80 % African American) completed the Youth Self Report for externalizing and internalizing problems and a modified Trier Social Stress Task (mTSST). They also provided saliva samples for cortisol and alpha-amylase (AA) prior to and 5, 20 and 40 min post-mTSST. Analyses revealed a positive cortisol-sAA coordination, with a 1% increase in cortisol corresponding to a 0.20 % average increase in sAA in response to stress. Higher degrees of within-person cortisol-sAA coordination predicted more behavior problems. The cortisol-sAA coordination explained 28 % and 10 % of the variance in externalizing and internalizing problems, much larger than when stress dynamics of single systems or the interaction of cortisol (AUCi) and sAA (AUCi) were predictors. Findings highlight the importance of multisystem interplay in stress responding in understanding behavior problems. Individuals with more behavior problems may have difficulty turning off their "fight or flight" ANS response, with this system remaining active to the stimulating influence of cortisol even when cortisol's stimulating effects should have dissipated.

Overestimating Self-Blame for Stressful Life Events and Adolescents' Latent Trait Cortisol: The Moderating Role of Parental Warmth.

Cognitive interpretations of stressful events impact their implications for physiological stress processes. However, whether such interpretations are related to trait cortisol-an indicator of individual differences in stress physiology-is unknown. In 112 early adolescent girls (M age = 12.39 years), this study examined the association between self-blame estimates for past year events and latent trait cortisol, and whether maternal warmth moderated effects. Overestimating self-blame (versus objective indices) for independent (uncontrollable) events was associated with lower latent trait cortisol, and maternal warmth moderated the effect of self-blame estimates on latent trait cortisol for each dependent (at least partially controllable) and interpersonal events. Implications for understanding the impact of cognitive and interpersonal factors on trait cortisol during early adolescence are discussed.

Early adversity and internalizing symptoms in adolescence: Mediation by individual differences in latent trait cortisol.

Research suggests that early adversity places individuals at risk for psychopathology across the life span. Guided by concepts of allostasis and allostatic load, the present study examined whether early adversity contributes to the development of subsequent internalizing symptoms through its association with traitlike individual differences in hypothalamic-pituitary-adrenal axis regulation. Early adolescent girls (n = 113; M age = 12.30 years) provided saliva samples at waking, 30 min postwaking, and bedtime over 3 days (later assayed for cortisol). Objective contextual stress interviews with adolescents and their mothers were used to assess the accumulation of nine types of early adversity within the family environment. Greater early adversity predicted subsequent increases in internalizing symptoms through lower levels of latent trait cortisol. Traitlike individual differences in hypothalamic-pituitary-adrenal axis activity may be among the mechanisms through which early adversity confers risk for the development of psychopathology.

Linking testosterone and antisocial behavior in at-risk transitional aged youth: Contextual effects of parentification.

Parentification refers to parents bestowing adult-like roles on children within families, and studies have linked parentification to individual differences in risk and resilience. The depth of our understanding of the pathways that translate parentification into risk for negative developmental outcomes remains shallow. This study examined whether parentification has a contextual effect moderating the expression of links between testosterone and antisocial behavior. Eighty-three participants (M age = 21.37 years, SD = 1.87; 48% Black; 60% female) were interviewed initially and one year later. Audio Computer Assisted Self-Interview methods were used to measure parentification and antisocial behavior. Saliva was sampled on multiple occasions and later assayed for testosterone. Results revealed, for both sexes, testosterone was positively associated with antisocial behavior at baseline and at follow-up when participants scored low on perceived benefits of parentification. This relationship became weaker as levels of perceived benefits of parentification increased. At the highest levels of perceived benefits of parentification, testosterone and antisocial behavior were inversely related. The findings suggest a potentially important role for perceptions of parentification as a moderator for the expression of hormone-behavior relationships and are discussed in terms of implications for the biosocial model of the family.

Testosterone and Proactive-Reactive Aggression in Youth: the Moderating Role of Harsh Discipline.

This study tests a biosocial model of the link between testosterone and proactive-reactive aggression in youth at varying levels of harsh discipline. Given that proactive aggression is used to gain power and status and the importance of social learning in its formation, we hypothesized that testosterone would be associated with proactive aggression at higher levels of harsh discipline, and that this relationship would be more pronounced in boys than girls. Participants (n = 445; 50% male; M age = 11.92 years; 80% African-American) and their caregivers completed questionnaires including demographics, conflict tactics, and proactive-reactive aggression. Youth also provided a saliva sample for testosterone. Analyses revealed an interaction between testosterone and harsh discipline on proactive aggression in both boys and girls, and an interaction between testosterone and harsh discipline on reactive aggression in boys only. For those experiencing high levels of harsh discipline, testosterone was positively associated with proactive aggression, with the magnitude of the association increasing as harsh discipline increased. For below average levels of harsh discipline, there were protective effects of high testosterone for boy's reactive aggression and for girl's proactive aggression. The findings support basic tenets of the biosocial model which suggest that links between testosterone and aggressive behavior are dependent on contextual forces, highlighting the complex relationship between hormones, social context, and aggression. Novel findings include protective effects of high testosterone for those exposed to low levels of harsh discipline. Findings are discussed in light of the context-contingency effect and also within the differential susceptibility framework.

The Cognitive, Affective, and Somatic Empathy Scales (CASES) for Children.

Although the assessment of empathy has moved from general empathy to differentiating between cognitive and affective empathy, no instruments have assessed somatic (motor) empathy, and none have separated positive from negative affect empathy. The main objective of this study was to develop a 30-item self-report cognitive, affective, and somatic empathy scale (CASES) with positive and negative affect components for use with children and adolescents. A community sample of 428 male and female 11-year-olds completed the CASES together with validity questionnaires and were assessed on IQ. Caregivers reported on callous-unemotional traits, behavior problems, social adversity, and paternal criminality. Confirmatory factor analysis provided support for a 3-factor cognitive-affective-somatic structure of CASES and support for a broader 6-factor model of empathy. Configural and metric factor invariance across genders was established. Good internal consistency was obtained for the main scales. Criterion validity was established by lower empathy in callous-unemotional children. Incremental and predictive validity was documented by empathy at baseline predicting 12 months later to callous-unemotional traits after controlling for baseline callous-unemotional traits. Discriminant validity was documented by empathy being unrelated to internalizing behavior problems and differentially related to proactive and reactive forms of aggression. Construct validity was documented by lower empathy being associated with lower IQ, being male, more externalizing behavior problems, and criminality in the biological parent. Results provide initial support for a brief but multidimensional empathy scale with good sampling and face validity that can be used with children and adolescents.

Effects of harsh parenting and positive parenting practices on youth aggressive behavior: The moderating role of early pubertal timing.

Prior research indicates that early pubertal timing is associated with aggressive behavior, particularly in the context of adversity as postulated in the contextual amplification hypothesis. However, few studies have examined harsh parenting as the context for the effect of early pubertal timing. Even fewer studies have tested the interactive effect of early pubertal timing and positive parenting on aggressive behavior. In this study, we tested the proposition that early pubertal timing, contrary to the general conception of it as a vulnerability, indexed susceptibility, and thus early maturing individuals were affected more by their environment in a "for better and for worse" manner. The sample consisted of 411 community-recruited youth aged 11-12 years (51% boys, 80% African Americans). Participants reported Tanner Stages of pubertal development, aggressive behavior and harsh parenting practice of their parents. Puberty scores were standardized with groups of the same age, sex, and ethnicity, and those that scored the top one-third were defined as early maturing individuals. Parents reported youth's aggressive behavior and their parenting practices towards the youth, including harsh parenting and positive parenting. Early pubertal timing significantly moderated the relationship between harsh/positive parenting and aggressive behavior. Specifically, harsh parenting was positively associated with aggressive behavior to a larger degree among early maturing individuals than among on-time/late-maturing individuals. Positive parenting was inversely associated with aggressive behavior but only among early maturing individuals. This study is the first to document support for early pubertal timing as susceptibility to the environmental influences in relation to aggressive behavior. Theoretical and intervention implications are discussed.

Measurement of cortisol in saliva: a comparison of measurement error within and between international academic-research laboratories.

OBJECTIVE: Hundreds of scientific publications are produced annually that involve the measurement of cortisol in saliva. Intra- and inter-laboratory variation in salivary cortisol results has the potential to contribute to cross-study inconsistencies in findings, and the perception that salivary cortisol results are unreliable. This study rigorously estimates sources of measurement variability in the assay of salivary cortisol within and between established international academic-based laboratories that specialize in saliva analyses. One hundred young adults (Mean age: 23.10 years; 62 females) donated 2 mL of whole saliva by passive drool. Each sample was split into multiple- 100 µL aliquots and immediately frozen. One aliquot of each of the 100 participants' saliva was transported to academic laboratories (N = 9) in the United States, Canada, UK, and Germany and assayed for cortisol by the same commercially available immunoassay. RESULTS: 1.76% of the variance in salivary cortisol levels was attributable to differences between duplicate assays of the same sample within laboratories, 7.93% of the variance was associated with differences between laboratories, and 90.31% to differences between samples. In established-qualified laboratories, measurement error of salivary cortisol is minimal, and inter-laboratory differences in measurement are unlikely to have a major influence on the determined values.
