- The genetic and environmental basis of a well-replicated association between antisocial behavior (ASB) and resting heart rate was investigated in a longitudinal twin study, based on two measurements between the ages of 9 and 14 years. ASB was defined as a broad continuum of externalizing behavior problems, assessed at each occasion through a composite measure based on parent ratings of trait aggression, delinquent behaviors, and psychopathic traits in their children. Parent ratings of ASB significantly decreased across age from childhood to early adolescence, although latent growth models indicated significant variation and twin similarity in the growth patterns, which were explained almost entirely by genetic influences. Resting heart rate at age 9-10 years old was inversely related to levels of ASB but not change patterns of ASB across age or occasions. Biometrical analyses indicated significant genetic influences on heart rate during childhood, as well as ASB throughout development from age 9 to 14. Both level and slope variation were significantly influenced by genetic factors. Of importance, the low resting heart rate and ASB association was significantly and entirely explained by their genetic covariation, although the heritable component of heart rate explained only a small portion (1-4%) of the substantial genetic variance in ASB. Although the effect size is small, children with low resting heart rate appear to be genetically predisposed toward externalizing behavior problems as early as age 9 years old.

- Comorbidity between internalizing (anxious, depressive) and externalizing (aggressive, delinquent) behavior is a well-established and common clinical reality throughout the lifespan, but perhaps becomes more significance in adolescence, when individuals are awarded more freedom. However, the genetic and environmental etiology of this comorbidity has rarely been examined in a behavioral genetic setting, especially during the period of adolescence. Additionally, research suggests that while caregivers may be more reliable reporters of externalizing behavior in youth, youth themselves are more reliable reporters of internalizing symptoms, raising the question of how different raters affect data patterns. Using the parent report Child Behavior Checklist (CBCL) as well as the youth report version (Youth Self Report—YSR), this research uses a twin study design to examine the etiology of coexisting internalizing and externalizing symptoms in mid adolescence (age 14–16 years) using a common pathway model that examined all data concurrently. Female comorbidity was accounted for by genetic and shared environmental influences, and male comorbidity by shared environmental influences, exclusively. Genetic influences emerged for all but self-report male externalizing behavior. Every scale showed unique influences as well, some of which were correlated between same-rater scales (e.g. parent report internalizing and externalizing), suggesting that some of the influences on covariation are rater-specific. These results contribute to our understanding of the nature of comorbid psychological disorders during adolescence, and suggest the importance of shared environment to the development of both internalizing and externalizing behavior

- The Southern California Twin Register at the University of Southern California (USC) was initiated in 1984 and continues to provide an important resource for studies investigating genetic and environmental influences on human behavior. This article provides an update on the current register and its potential for future twin studies using recruitment through school district databases and voter records. An overview is also provided for an ongoing longitudinal twin study investigating the development of externalizing psychopathology from childhood to young adulthood, the USC Study of Risk Factors for Antisocial Behavior. Characteristics of the twins and their families are presented, including recruitment and participation rates, as well as attrition analyses and a summary of key findings to date.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- There has been a longstanding interest in autonomic activity in relation to criminal deviancy, antisocial behavior (ASB), and psychopathy. Among the autonomic measures studied to date, considerable evidence supports low rest-ing heart rate (HR) early in life as one of the most robust predictors of later ASB (Farrington, 1997). Some studies have examined stimulation seeking and fearlessness as possible trait factors accounting for the low HR/ASB rela-tionship (Hammerton et al., 2017; Portnoy et al., 2014; Sijstema et al., 2010), but the individual difference basis of this relationship remains unclear. The current study tested for associations of resting HR at ages 9–10 with triarchic psychopathy traits of boldness, meanness, and disinhibition along with ASB later in life (ages 19–20) among participants (N = 687) from a longitudinal investigation, the Risk Factors for Antisocial Behavior (RFAB; Baker et al., 2013) project. Resting HR was negatively associated with both violent and nonviolent behavior, and with externalizing problems more broadly. It was also related negatively to triarchic traits of boldness and disinhibition, with the relationship somewhat stronger for boldness. Importantly, boldness and disinhibition each accounted for significant variance in associations of low resting HR with particular types of ASB. Implications of these findings for our understanding of the nature and bases of the low HR–antisocial behavior relationship will be discussed.

- The triarchic model was advanced as an integrative, trait-based framework for investigating psychopathy using different assessment methods and across developmental periods. Recent research has shown that the triarchic traits of boldness, meanness, and disinhibition can be operationalized effectively in youth, but longitudinal research is needed to realize the model's potential to advance developmental understanding of psychopathy. We report on the creation and validation of scale measures of the triarchic traits using questionnaire items available in the University of Southern California Risk Factors for Antisocial Behavior (RFAB) project, a large-scale longitudinal study of the development of antisocial behavior that includes measures from multiple modalities (self-report, informant rating, clinical-diagnostic, task-behavioral, physiological). Using a construct-rating and psychometric refinement approach, we developed triarchic scales that showed acceptable reliability, expected intercorrelations, and good temporal stability. The scales showed theory-consistent relations with external criteria including measures of psychopathy, internalizing/externalizing psychopathology, antisocial behavior, and substance use. Findings demonstrate the viability of measuring triarchic traits in the RFAB sample, extend the known nomological network of these traits into the developmental realm, and provide a foundation for follow-up studies examining the etiology of psychopathic traits and their relations with multimodal measures of cognitive-affective function and proneness to clinical problems.

- Purpose: Resting heart rate (RHR) is a well-established biological risk factor for criminal behavior. However, potential moderating effects of social risk factors like socioeconomic status on this relationship remain unclear. The current study sought to clarify the moderating impact of socioeconomic status on the relation between low RHR in childhood and adolescence and subsequent legal system involvement by young adulthood.Methods: A subset of twins and triplets from the Risk Factors for Antisocial Behavior (RFAB) project (N = 347) were utilized to test hypotheses. Logistic regression analyses were performed to test for a moderating effect of socioeconomic status on the relationship between RHR and later law enforcement involvement (trouble with police, arrest).Results: Resting HR and SES were individually associated with an increased likelihood of being in trouble with the police and being arrested. In addition, RHR and SES in adolescence interacted to predict trouble with the police and arrest history by young adulthood, such that low RHR predicted these outcomes among adolescents who remained in low SES backgrounds.Conclusions: Adolescents who remain in low socioeconomic backgrounds from childhood will be a particularly important group to target in terms of treatment efforts to prevent criminal behavior.

- Low resting heart rate (HR) is a known risk indicator for the development of antisocial behavior (ASB) and other clinical problems. Stimulation seeking and fearlessness have been explored as factors underlying the HR/ASB relationship, but these have often been conflated, which has complicated interpretation. We examined HR's associations with ASB and other outcomes in terms of biobehavioral traits described by the triarchic model of psychopathy using data (N = 710) from a longitudinal study of ASB risk. Low resting HR in childhood was related to adult ASB, and covariance between ASB and traits of disinhibition and boldness largely accounted for this association. In addition, low childhood HR was related to greater externalizing problems and fewer internalizing problems in adulthood; disinhibition accounted for the former association, and boldness accounted for the latter. Findings indicate a role for both disinhibition and boldness in associations between early HR and later clinical outcomes and have implications for theory and practice.

- There has been a longstanding interest in relationships between autonomic activity during fear conditioning paradigms and antisocial behavior and psychopathy. A considerable body of work has explored electrodermal and cardiovascular responses both in anticipation of, and in response to, fear conditioning paradigms in antisocial participants (Hare 1965; Hare & Quinn, 1976). However, there is a lack of work exploring these associations in adolescent populations, and how these associations may relate to the triarchic model of psychopathy (Patrick, Fowles, & Krueger, 2009). The current study examined relationships between skin conductance responses (SCRs) and heart rate reactivity (HRR) to a countdown task at ages 9– 10, and the triarchic psychopathy traits at ages 9– 10, 14– 15, and 19– 20 in a longitudinal sample (N = 695) of twins from the Risk Factors for Antisocial Behavior (RFAB; Baker et al., 2013) project. Children and adolescents high in boldness, both rated by themselves and their parents, demonstrated reduced skin conductance both in anticipation of and in reaction to the loud blast. Similar patterns were also demonstrated for heart rate (HR); children and adolescents high in boldness had less HR change during the countdown, and reduced HRR to the blast itself. Implications of these findings for our understanding of the role of boldness in autonomic reactivity to fear conditioning paradigms will be discussed.
