Paths from mother-child and father-child relationships to externalizing behavior problems in children differing in electrodermal reactivity: a longitudinal study from infancy to age 10

Affective and Behavioral Responses to Time-Out in Preschool Children With Conduct Problems and Varying Levels of Callous-Unemotional Traits

Punishment insensitivity characterizes individuals with callous-unemotional (CU) traits. This has been put forward as an explanation for their persistent conduct problems despite intervention. The purpose of the current study was to compare the emotional and behavioral responses to parent-implemented time-out within a behavioral parent training intervention between children with conduct problems who are high versus low on CU traits. Children (N = 87; M age = 4.88 years, SD = 1.32; 78% male) referred to a specialty clinic for the treatment of conduct problems were observed and coded during time-out, and their parents rated their conduct problem severity and CU traits using psychometrically robust measures. Children with conduct problems and high CU traits showed significantly more calm/neutral emotion and less negative emotion upon initial placement in time-out by parents, but did not engage in more negative behaviors or spend longer in time-out relative to children with conduct problems alone. After a minimum of 3 weeks of exposure to this form of parental discipline, most children complied with effective parental commands in that they did not require time-out for noncompliance during the fourth discipline-focused treatment session. Findings have implications for understanding why children with CU traits continue showing high levels of conduct problems post behavioral interventions, and they lend further support for the need to personalize treatment to their distinct needs.

Environmental variables influence the relationship between maternal depressive symptoms and toddlers' neurocognitive and affective outcomes

Motherhood is often associated with joy, but it can pose significant challenges, and in some instances lead to perinatal mental health problems. Maternal depressive symptoms can hinder a mother's ability to attune to her infant's needs, potentially affecting caregiving quality and emotional support. This study examines how parenting style and a cognitively stimulating home environment (i.e., individual level) and relative social deprivation (i.e., area level) contribute to the relationship between maternal depressive symptoms and offspring's neurocognitive and affective outcomes at 18 months. Participants were 479 mothers and children recruited as part of the Developing Human Connectome Project. Maternal postnatal depressive symptoms were assessed at term with the Edinburgh Postnatal Depression Scale. At a median corrected age of 18.4 months (range 17.3-24.3) children's outcomes were evaluated with the Bayley Scales of Infant and Toddler Development, Third Edition, the parent-rated Child Behaviour Checklist 1½ - 5 and the Early Childhood Behaviour Questionnaire. The Parenting Scale measured dysfunctional parenting in discipline situations; the Cognitively Stimulating Parenting Scale assessed experiences promoting cognitive stimulation in the home. Family socioeconomic status was evaluated using the Index of Multiple Deprivation. Toddler's outcomes were summarised into latent dimensions labelled 'neurocognitive' and 'affective'. Results from bootstrapped-based mediation analysis showed that a permissive parenting style and a less cognitively stimulating home environment modified the relationship between depressive symptoms and toddlers' neurocognitive outcomes. However, other factors, such as relative social deprivation and parental over-reactivity, did not alter this. Results also showed that an over-reactive parenting style modified the relationship between maternal depressive symptoms and toddlers' reduced capacity for effective emotional regulation, while relative social deprivation, permissive parenting and a cognitively stimulating home environment did not. These findings highlight the importance of understanding how environmental factors interact with parenting styles, and influence child development. The study emphasizes the need for interventions that create stable and supportive environments, mitigating the impact of suboptimal parenting on children's developmental outcomes.

Considering heterogeneity within negative emotionality can inform the distinction between diathesis-stress and differential susceptibility: Children's early anger and fear as moderators of effects of parental socialization on antisocial conduct

The importance of interactions between child temperament and parenting has been accepted ever since Thomas and Chess (1977) proposed their "goodness-of-fit" construct, but over the last three decades, pertinent research has grown exponentially. Researchers examining child characteristics that can moderate the effects of socialization have tested increasingly complex, nuanced, and sophisticated models, largely inspired by the highly influential frameworks of child plasticity or differential susceptibility (Belsky & Pluess, 2009). Yet, multiple questions remain unsettled. We addressed four such questions as applied to predicting children's observed disregard for rules at age 4.5 in a study of 200 community families from the US Midwest. (a) We examined children's observed negative emotionality at 16 months, most commonly seen as a plasticity "trait," but separating anger and fear proneness, which may differently moderate effects of socialization. (b) We examined two separate aspects of observed parental socialization at age 3, mutually responsive orientation and power assertion. (c) We distinguished analytically diathesis-stress from differential susceptibility. (d) We examined all effects in mother- and father-child relationships. We supported both diathesis-stress and differential susceptibility, depending on the facet of negative emotionality, the aspect of socialization considered, and parental gender, highlighting the nuanced nature of the processes involved.

Antecedents and Consequences of Child Externalizing Problems: Differences in Dynamic Parent-Child Processes

Given that noncompliance is the most common externalizing problem during middle childhood and reliably predicts significant conduct problems, innovations in elucidating its etiology are sorely needed. Evaluation of in-the-moment antecedents and consequences of child noncompliance improves traction on this goal, given that multiple theories contend that child noncompliance and parent behavior mutually influence each other through negative reciprocation as well as contingent praise processes. Among a sample of 140 families (child age: 6-10 years; 32.1% female), the present study capitalized on intensive repeated measures of observed child noncompliance and parent negative talk and praise objectively coded during three unique tasks. We employed dynamic structural equation modeling to evaluate within-dyad parent-child behavioral dynamics and between-dyad differences therein. Results provided mixed support for hypotheses and suggested that antecedents and consequences of child noncompliance differed according to task demands and child ADHD symptoms. Contrary to models of coercive cycles, during child-led play, parent negative talk was more likely following prior child noncompliance, but child noncompliance was less likely following prior parent negative talk. As expected, during parent-led play, parent praise was less likely following prior child noncompliance, which was also less likely following prior parent praise. Relative to youth with fewer symptoms, for children with elevated ADHD symptoms, during a challenging clean-up task, child noncompliance was less stable and less contingent on prior parent negative talk. Results are discussed in terms of their implications of real-time parent-child interactions for typical and atypical development of externalizing problems.

Domain specificity of differential susceptibility: Testing an evolutionary theory of temperament in early childhood

According to differential susceptibility theory (DST), some children may be more sensitive to both positive and negative features of the environment. However, research has generated a list of widely disparate temperamental traits that may reflect differential susceptibility to the environment. In addition, findings have implicated these temperament × environment interactions in predicting a wide variety of child outcomes. This study uses a novel evolutionary model of temperament to examine whether differential susceptibility operates in a domain-general or domain-specific manner. Using a racially and socioeconomically diverse sample of 243 preschoolers and their parents (56% female; 48% African American), we examined the interactions between maternal and paternal parenting quality and two evolutionary informed temperament profiles (i.e., Hawks and Doves) in predicting changes in teacher-reported conduct problems and depressive symptoms from preschool to first grade. Results suggest that differential susceptibility operates in a domain-specific fashion. Specifically, the "Hawk" temperament was differentially susceptible to maternal parenting in predicting externalizing problems. In contrast, the "Dove" temperament was susceptible to both paternal and maternal parenting quality in predicting changes in depressive symptoms. Findings provide support for an integrative framework that synthesizes DST with an evolutionary, function-based approach to temperament.

Negative parenting and functions of relational aggression: The moderating roles of gender and physiological reactivity

Dimensions of negative parenting, including permissive, authoritarian, and psychologically controlling parenting behaviors, are associated with children's engagement in relational aggression. However, some youth may be more strongly influenced by negative parenting than others, and effects may depend on whether aggression is proactive or reactive in function. In a community sample of 236 preadolescent children followed over 1 year, we examined whether children's skin conductance level reactivity (an index of "fight or flight" response) and gender moderated links between parents' self-reported negative parenting behaviors and increases in children's teacher-reported proactive and reactive relational aggression. Findings indicated that negative parenting predicted increases in proactive and reactive relational aggression, and, consistent with differential susceptibility theory, effects often emerged among highly reactive youth. Associations between negative parenting and proactive relational aggression emerged for boys but not girls. Results tentatively suggest that associations between parenting and aggression vary by the function of aggression, children's physiological reactivity to stress, and gender, although results should be interpreted with caution due to high levels of missing data. Implications for theory and intervention are discussed.

The impact of family socioeconomic status on prosocial behavior: a survey of college students in China

College students’ prosocial behaviors have been shown to help them to attain honor, achieve happiness, and improve their social adaptation. This study was designed to examine the mediating roles of parent-child attachment and emotion regulation self-efficacy in the relationship between family socioeconomic status and prosocial behaviors. A survey was conducted among 458 college students randomly selected from six universities in two Chinese provinces characterized by a medium level of higher education development. The model was verified by structural equation modeling and mediation effect testing methods. The study revealed that family socioeconomic status had a positive effect on parent-child attachment and emotion regulation self-efficacy, but had no direct effect on the students’ prosocial behavior. Moreover, parent-child attachment and emotional regulation self-efficacy both mediated the influence of family socioeconomic status on the prosocial behavior of college students. Finally, family socioeconomic status affected the prosocial behavior of college students through the chain of parent-child attachment and emotional self-efficacy.

Parent-child relationship quality and adolescent health: Testing the differential susceptibility and diathesis-stress hypotheses in African American youths

This study tested two competing models of differential susceptibility and diathesis-stress in a prospective longitudinal study of African American youths (N = 935). It examined whether individual variations in the functioning of the hypothalamic-pituitary-adrenocortical axis at age 11 interact with middle childhood parent-child relationship quality to predict mental and physical health problems in adolescence (ages 11-15 years old). Adolescent boys with lower levels of cortisol reactivity to laboratory challenges had the highest levels of internalizing problems if they experienced a high conflictual relationship with their parents. Equally low-reactive boys, however, reported the lowest number of physical illnesses if their relationship with their parents was characterized by high levels of intimacy and support.

[Psychometric Properties of a German Translation of the Parental Bonding Instrument]

Parenting behavior affects a child's development as well as the etiology and treatment of mental disorders. The Parental Bonding Instrument (PBI; Parker, Tupling & Brown, 1979) is a well-known measurement tool to retrospectively assess parenting styles. Yet, no sufficiently validated German version exists to date. Therefore, we developed an updated translation of the German PBI version (PBI-dt) and analyzed its psychometric properties in an online survey based on a sample of n=791 German-speaking participants with a focus on item and reliability characteristics, construct and criterion validity as well as factorial structure of the PBI-dt.Our results indicated good item characteristics and reliability (α=0.86-0.95). Correlations between PBI and CTQ-SF (Childhood Trauma Questionnaire Short Form) scales were in line with the literature. Significant differences in the reported parenting style were found between people with and without mental illness as well as between normal-weight and overweight people. These results indicated the presence of good construct and criterion validity. Confirmatory factor analyses indicated an acceptable model fit for all fit indices in the original 2-factor model of Parker et al. (1979) as well as in the 3-factor model with the scales CareCareCareCareCareCare, Discouragement of behavioral freedomDiscouragement of behavioral freedomDiscouragement of behavioral freedomDiscouragement of behavioral freedomDiscouragement of behavioral freedomDiscouragement of behavioral freedom and Denial of psychological autonomyDenial of psychological autonomyDenial of psychological autonomyDenial of psychological autonomyDenial of psychological autonomyDenial of psychological autonomy. A 3-factor structure provided additional information, e. g., a better differentiation between normal and overweight people. Hence, this German translation of the PBI has good psychometric properties and is a reliable measuring instrument.

Differences in mother-child and father-child RSA synchrony: Moderation by child self-regulation and dyadic affect

Parents and preschoolers show respiratory sinus arrhythmia (RSA) synchrony, but it is unclear how child self-regulation and the dyadic affective climate shape RSA synchrony and how synchrony differs for mothers and fathers. We examined child average RSA, externalizing problems, and dyadic positive affect as moderators of the synchrony of dynamic, within-epoch child and parent RSA reactivity during a challenging task. Mothers (N = 82) and fathers (N = 60) oversampled for familial risk participated with their 3-year-olds. For mothers, when children showed either higher externalizing or lower average RSA, negative RSA synchrony was observed as dynamic coupling of maternal RSA augmentation and child RSA withdrawal, suggesting inadequate support of the child during challenge. However, when children showed both higher externalizing and lower average RSA, indicating greater regulatory difficulties overall, positive synchrony was observed as joint RSA withdrawal. The same patterns were found for father-child RSA synchrony but instead with respect to the moderators of higher externalizing and lower dyadic positive affect. Findings suggest moderators of RSA synchrony differ by parent and shared positive affect plays a robust role in fathers' RSA reactivity and synchrony. Mothers may be more attuned to children's regulatory capacities, whereas fathers may be more influenced by the immediate behavioral context.

Paternal antisociality and growth in child delinquent behaviors: Moderating effects of child sex and respiratory sinus arrhythmia

Children of fathers with antisocial personality disorder (ASPD) are at risk for developing delinquency, and both biological and environmental mechanisms contribute. In this study, we test parasympathetic nervous system (PNS) function as a vulnerability/sensitivity attribute in predicting intergenerational associations between fathers' antisociality and children's delinquency scores. We followed 207 children (ages 8-12 years at intake; 139 boys) across three annual assessments. Fathers' antisociality was measured via maternal reports on the Family Interview for Genetic Studies (FIGS). At Year 1, children's resting respiratory sinus arrhythmia (RSA) was measured. At Years 1, 2, and 3, child delinquent behaviors were assessed using the delinquency subscale of the Youth Self-Report. At age 8, boys' delinquency scores were associated weakly with paternal antisocial behaviors. However, boys' delinquency scores increased steeply thereafter specifically for those who had fathers with higher antisocial symptoms. In addition, associations between delinquency and paternal antisociality were largest for boys with higher resting RSA. For girls, growth in delinquency was unrelated to both father antisociality and resting RSA. These findings (a) suggest moderating effects of children's age, sex, and PNS function on associations between father antisocial behavior and offspring delinquency; and (b) provide insights into differential vulnerability among children of fathers with ASPD.

Mapping the Specific Pathways to Early-Onset Mental Health Disorders: The "Watch Me Grow for REAL" Study Protocol

BACKGROUND

From birth, the human propensity to selectively attend and respond to critical super-stimuli forms the basis of future socio-emotional development and health. In particular, the first super-stimuli to preferentially engage and elicit responses in the healthy newborn are the physical touch, voice and face/eyes of caregivers. From this grows selective attention and responsiveness to emotional expression, scaffolding the development of empathy, social cognition, and other higher human capacities. In this paper, the protocol for a longitudinal, prospective birth-cohort study is presented. The major aim of this study is to map the emergence of individual differences and disturbances in the system of social-Responsiveness, Emotional Attention, and Learning (REAL) through the first 3 years of life to predict the specific emergence of the major childhood mental health problems, as well as social adjustment and impairment more generally. A further aim of this study is to examine how the REAL variables interact with the quality of environment/caregiver interactions.

METHODS/DESIGN

A prospective, longitudinal birth-cohort study will be conducted. Data will be collected from four assessments and mothers' electronic medical records.

DISCUSSION

This study will be the first to test a clear developmental map of both the unique and specific causes of childhood psychopathology and will identify more precise early intervention targets for children with complex comorbid conditions.

Respiratory sinus arrhythmia, parenting, and externalizing behavior in children with autism spectrum disorder

Children with autism spectrum disorder exhibit significant difficulties with emotion regulation. Respiratory sinus arrhythmia is a biomarker for processes related to emotion regulation, with higher baseline rates linked to beneficial outcomes. Although reduction in respiratory sinus arrhythmia in response to challenge can index adaptive processes in community samples, excessive withdrawal may suggest loss of regulatory control among children with clinical concerns. Psychophysiological risk for problems may be protected against or exacerbated by parenting environments more or less supportive of the development of children's regulatory competence. Respiratory sinus arrhythmia was examined in 61 children with autism spectrum disorder ages 6-10 years in relation to externalizing behavior, and parenting was considered as a moderator. Respiratory sinus arrhythmia was obtained during laboratory tasks, and positive parenting, negative parenting, and children's externalizing behaviors were each indexed through multiple methods. Respiratory sinus arrhythmia reactivity interacted with negative, but not positive parenting. Higher respiratory sinus arrhythmia reactivity was associated with more externalizing behavior under conditions of higher negative parenting, but with lower externalizing behavior at lower levels of negative parenting. Similarly, negative parenting was only associated with externalizing behaviors in the context of high child respiratory sinus arrhythmia reactivity. Implications for our understanding of emotion regulation in children with autism spectrum disorder, and for related interventions, are discussed.

Longitudinal Associations between Oppositional Defiant Symptoms and Interpersonal Relationships among Chinese Children

Children with oppositional defiant disorder (ODD) are at increased risk for developing poor relationships with people around them, but the longitudinal links between ODD symptoms and subsequent interpersonal functioning remain unclear. In the current study, we examined the bidirectional associations between ODD symptoms and children's relationships with parents, peers, and teachers. We included separate analyses for parent vs. teacher reports of ODD symptoms, with regard to subsequent interpersonal relationships. Participants included 256 children with ODD, recruited in China, along with their parents and teachers, assessed at three time points roughly two years apart. Parents and teachers reported child ODD symptoms at each time point, and children reported their perceptions of father- and mother-child attachment, peer relationships, and teacher-student relationships across the three time points. ODD symptoms reported either by parents or teachers predicted impairments in interpersonal functioning. Meanwhile, child interpersonal impairments with peers and teachers predicted subsequent increase in teacher-reported ODD symptoms. These findings highlight the importance of transactional models of influence-and of considering early intervention for ODD in protecting children from developing further deficits and impairments. Additionally, we discuss the perspectives of multiple informants on ODD symptoms, including their different patterns of association with subsequent interpersonal relationships.

Parenting, deviant peer affiliation, and externalizing behavior during adolescence: processes conditional on sympathetic nervous system reactivity

BACKGROUND

This study examined associations between permissive parenting, deviant peer affiliations, and externalizing behavior across mid to late adolescence in a plausible indirect effects model of change over time with deviant peer affiliation serving as the mediator. We also evaluated potential conditional indirect effects wherein these relationships may be moderated by sex and sympathetic nervous system (SNS) activity, indexed by skin conductance level (SCL) reactivity.

METHOD

Participants included 242 community-sampled adolescents (M = 15.79 years; 48% boys; 66% European American, 34% African American) with two additional longitudinal assessments lagged by 1 year. Permissive parenting, SCL reactivity, and sex were considered as time invariant predictors of repeated measures of deviant peer affiliation and externalizing behavior in latent growth models that tested whether any of the direct or indirect associations were conditional on sex or SCL reactivity.

RESULTS

Evidence was found for indirect effects of permissive parenting on externalizing behavior via deviant peer affiliation, but only for males with lower SCL reactivity to stress. Additionally, these effects were found on latent intercepts, but not slopes indexing change over time, perhaps reflecting established individual differences in relationships among these variables.

CONCLUSIONS

Findings are discussed in the context of biosocial models of adolescent development and risk factors that may inform interventions for vulnerable youth.

Longitudinal Associations of Parental Emotion Socialization and Children's Emotion Regulation: The Moderating Role of ADHD Symptomatology

Theory and research suggest that parents' reactions to children's emotions play a critical role in teaching children effective emotion regulation (ER) skills, but no studies have directly examined the role that parent emotion socialization plays in the development of ER in children with ADHD. Gaining insight into the causes of impaired ER, particularly in youth with ADHD who are known to have poor ER, has important theoretical and translational significance. The present study is the first to longitudinally examine whether emotion socialization predicts later physiological and adult-reported measures of ER in children with and without ADHD. It also sought to determine if these relations are moderated by ADHD symptoms. Participants were 61 children (31 girls, 30 boys; M = 10.67 years, SD = 1.28) with and without clinically significant ADHD symptoms. At Time 1, parent reports of emotion socialization and parent- and teacher-report of child ADHD symptoms were collected. At Time 2, child ER measures were collected based on parent- and teacher-report and physiological reactivity during an impossible puzzle and a social rejection task. Physiological measures included respiratory sinus arrhythmia and skin conductance level (SCL). Supportive parenting practices were associated with better parent-rated emotion regulation skills for all children and greater SCL reactivity for children with high ADHD symptoms. Non-supportive parenting reactions were associated with greater adult-rated emotional lability for children with high ADHD symptoms. Results highlight the importance of considering multiple aspects of ER, including physiological manifestations. Findings suggest that parents' use of adaptive emotion socialization practices may serve as a protective factor for children's ER development and may be particularly critical for youth with ADHD. Our findings support the use of interventions addressing parent emotion socialization to help foster better ER in children.

Obimon: An open-source device enabling group measurement of electrodermal activity

Electrodermal activity (EDA) provides the means to gauge the activity of the sympathetic nervous system. Assessment of EDA for research purposes requires measurement systems that are sensitive to small changes in arousal in the full measurement range, collecting, storing, and monitoring data. The objective behind designing a new open-source device was to be able to measure EDA simultaneously on many subjects, monitoring their activity in real time remotely and collecting high precision data suitable for analyses. To assure feasibility of simultaneous measurements on multiple subjects, the devices must be compact and wearable, without compromising data quality. Experiments were carried out using synchronized devices in group and single subject environments. Validity of EDA measurements of Obimon was demonstrated compared to a reference system (Nexus) during a breathing exercise, a short movie, and while exposed to loud computer-generated tones, using Pearson correlation, Passing-Bablok regression, and Bland-Altman analysis. Seamless management of several Obimons and real-time visualization of EDA via Android phone/tablet application from a large number of participants was demonstrated. Based on analyses of the data collected, we conclude that the Obimon device presented here is a valid and feasible tool for collecting EDA in single or multisubject environments.

Parenting, culture, and the development of externalizing behaviors from age 7 to 14 in nine countries

Using multilevel models, we examined mother-, father-, and child-reported (N = 1,336 families) externalizing behavior problem trajectories from age 7 to 14 in nine countries (China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States). The intercept and slope of children's externalizing behavior trajectories varied both across individuals within culture and across cultures, and the variance was larger at the individual level than at the culture level. Mothers' and children's endorsement of aggression as well as mothers' authoritarian attitudes predicted higher age 8 intercepts of child externalizing behaviors. Furthermore, prediction from individual-level endorsement of aggression and authoritarian attitudes to more child externalizing behaviors was augmented by prediction from cultural-level endorsement of aggression and authoritarian attitudes, respectively. Cultures in which father-reported endorsement of aggression was higher and both mother- and father-reported authoritarian attitudes were higher also reported more child externalizing behavior problems at age 8. Among fathers, greater attributions regarding uncontrollable success in caregiving situations were associated with steeper declines in externalizing over time. Understanding cultural-level as well as individual-level correlates of children's externalizing behavior offers potential insights into prevention and intervention efforts that can be more effectively targeted at individual children and parents as well as targeted at changing cultural norms that increase the risk of children's and adolescents' externalizing behavior.

Sympathetic Under-Arousal and Externalizing Behavior Problems in Children with Autism Spectrum Disorder

Children with autism spectrum disorder (ASD) commonly exhibit co-occurring externalizing behavior problems, which can impede learning opportunities and contribute significantly to caregiver stress. Substantial theory and research has linked under-arousal of the sympathetic nervous system to increased externalizing problems in children without ASD, but under-arousal has not been considered as an explanatory mechanism for individual differences among children with ASD. We tested the notion that lower electrodermal activity (EDA) would predict more externalizing problems in children with ASD, and considered the degree to which parent co-regulatory support could buffer this risk. Forty children with ASD between the ages of 4 and 11 years and their primary caregivers participated in a laboratory visit that included various play, compliance, and problem-solving regulatory tasks. EDA was measured through wireless wrist sensors, parental scaffolding was observed during a dyadic problem-solving task, and parents rated their children's externalizing behavior problems. As predicted, low EDA during the compliance-oriented tasks directly predicted higher child externalizing problems. Parental scaffolding moderated the link between under-arousal during the problem-solving regulatory tasks and externalizing problems such that the relation was observed in the context of low, but not high, support. Implications for relevant theories (e.g., fearlessness theory, stimulation-seeking theory) are discussed, and the potential for psychophysiological patterns to inform intervention with these children is considered.

The Security Scale as a measure of attachment: meta-analytic evidence of validity

This meta-analysis evaluated the psychometric properties of the Security Scale (SS; k = 57 studies), a measure specifically designed to assess attachment in middle childhood, using several criteria: stability over time, associations with other attachment measures, relations with caregiver sensitivity, and associations with theoretically driven outcomes. The SS demonstrated moderate stability and meaningful associations with other attachment measures and caregiver sensitivity. Furthermore, the SS showed significant associations with developmental correlates of attachment: school adaptation, emotional and peer social competence, self-esteem, and behavioral problem. Some effect sizes varied as a function of socioeconomic status (SES; peer social competence and maladjustment) and publication status (emotional competence, peer social competence, and self-esteem). The association between the SS and our constructs of interest were, for the most part, independent of geographical location and child gender or age. Overall, findings suggest that the SS is a robust measure of attachment in middle childhood and early adolescence.

A cascade from disregard for rules of conduct at preschool age to parental power assertion at early school age to antisocial behavior in early preadolescence: Interplay with the child's skin conductance level

Young children's disregard for conduct rules (failing to experience discomfort following transgressions and violating adults' prohibitions) often foreshadows future antisocial trajectories, perhaps in part because it elicits more power-assertive parental discipline, which in turn promotes children's antisocial behavior. This process may be particularly likely for children with low skin conductance level (SCL). In 102 two-parent community families, we tested a model in which children's SCL, assessed at 8 years, was posed as a moderator of the cascade from children's disregard for conduct rules at 4.5 years to parents' power assertion at 5.5 and 6.5 years to antisocial behavior at 10 and 12 years. Children's disregard for conduct rules was observed in scripted laboratory paradigms, parents' power assertion was observed in discipline contexts, and children's antisocial behavior was rated by parents. Conditional process analyses revealed that the developmental cascade from early disregard for rules to future parental power assertion to antisocial outcomes occurred only for the children with low SCL (below median), but not their high-SCL (above median) peers. By elucidating the specific interplay among children's disregard for rules, the parenting they receive, and their psychophysiology, this study represents a developmentally informed, multilevel approach to early etiology of antisocial behavior.

Infant Attachment Moderates Paths From Early Negativity to Preadolescent Outcomes for Children and Parents

Although infant attachment has been long seen as key for development, its long-term effects may be complex. Attachment may be a catalyst or moderator of future developmental sequelae rather than a source of main effects. In 102 mothers, fathers, and infants, attachment was assessed at 15 months; children's negativity (rejection of parental rules and modeling attempts) at 25, 38, 52, and 67 months; and developmental outcomes (the child's parent-rated externalizing problems and the parent-child observed relationship quality) at ages 10 and 12. In both mother-child and father-child relationships, children's higher negativity was associated with more detrimental outcomes but only in dyads with formerly insecure infants. Infant insecurity appears to amplify detrimental cascades, whereas infant security appears to defuse such risks.

Parental management of peers and autonomic nervous system reactivity in predicting adolescent peer relationships

The present study examined sympathetic and parasympathetic indices of autonomic nervous system reactivity as moderators of the prospective association between parental management of peers via directing of youths' friendships and peer adjustment in a sample of typically developing adolescents. Participants included 246 adolescents at Time 1 (T1) [47% boys; 66% European American (EA), 34% African American (AA)] and 226 adolescents at Time 2 (T2; 45% boys; 67% EA, 33% AA). Adolescents were approximately 16 and 17 years old at T1 and T2, respectively. To address study aims, a multiinformant, multimethod longitudinal design was utilized. Skin conductance level (SCL) and respiratory sinus arrhythmia (RSA) were measured during a baseline period and challenge task (star-tracing). Reactivity was computed as a difference score between the task and baseline period. Results from path models revealed that higher levels of mother-reported parental directing predicted decreases in adolescent-reported peer rejection and friends' deviant behavior from T1 to T2 at relatively low levels of physiological arousal in response to challenge (i.e., low SCL reactivity, RSA augmentation). Further, exploratory analyses indicated that directing was associated with decreases in friends' deviant behavior and peer rejection particularly among boys who exhibited lower levels of physiological arousal, but increases in friends' deviant behavior among boys who exhibited higher levels of arousal reflected in RSA withdrawal only. Overall, findings are consistent with prior studies revealing the benefits of parental behavioral control for underaroused youth, contributing to the growing literature on the interplay of parenting and physiological factors in the adolescent peer domain.

Electrodermal Reactivity Moderates the Prospective Association Between Peer Victimization and Depressive Symptoms in Early Adolescence

The present study examined whether skin conductance level reactivity (SCLR) moderated prospective associations linking peer victimization with externalizing behaviors and depressive symptoms across the transition to middle school. Participants included 123 early adolescents (M age = 12.03 years at T1; 50% male; 58.5% European Americans, 35% African Americans, 6.5% of other races/ethnicities). At Time 1, SCLR was measured in the context of peer-evaluative challenges, and early adolescents and teachers reported on peer victimization. At Time 1 and Time 2, early adolescents and parents reported on depressive symptoms and externalizing behaviors, respectively. SCLR moderated prospective associations between peer victimization and depressive symptoms, such that both adolescent- and teacher-reported peer victimization predicted higher Time 2 depressive symptoms more strongly at lower levels of SCLR compared to higher levels of SCLR. SCLR did not moderate the prospective association between peer victimization and externalizing behaviors. Results of the present study suggest that low reactivity in the inhibitory dimension of the sympathetic nervous system may increase vulnerability to depressive symptoms in the context of peer victimization, whereas higher reactivity may operate as a protective factor.

Permissive Parenting, Deviant Peer Affiliations, and Delinquent Behavior in Adolescence: the Moderating Role of Sympathetic Nervous System Reactivity

The present study examined two measures of sympathetic nervous system (SNS) activity as moderators of the indirect path from permissive parenting to deviant peer affiliations to delinquency among a community sample of adolescents. Participants included 252 adolescents (M = 15.79 years; 53 % boys; 66 % European American, 34 % African American). A multi-method design was employed to address the research questions. Two indicators of SNS reactivity, skin conductance level reactivity (SCLR) and cardiac pre-ejection period reactivity (PEPR) were examined. SNS activity was measured during a baseline period and a problem-solving task (star-tracing); reactivity was computed as the difference between the task and baseline periods. Adolescents reported on permissive parenting, deviant peer affiliations, externalizing behaviors, and substance use (alcohol, marijuana). Analyses revealed indirect effects between permissive parenting and delinquency via affiliation with deviant peers. Additionally, links between permissive parenting to affiliation with deviant peers and affiliation with deviant peers to delinquency was moderated by SNS reactivity. Less SNS reactivity (less PEPR and/or less SCLR) were risk factors for externalizing problems and alcohol use. Findings highlight the moderating role of SNS reactivity in parenting and peer pathways that may contribute to adolescent delinquency and point to possibilities of targeted interventions for vulnerable youth.

Decline in the Quality of Family Relationships Predicts Escalation in Children's Internalizing Symptoms from Middle to Late Childhood

An integration of family systems perspectives with developmental psychopathology provides a framework for examining the complex interplay between family processes and developmental trajectories of child psychopathology over time. In a community sample of 98 families, we investigated the evolution of family relationships, across multiple subsystems of the family (i.e., interparental, mother-child, father-child), and the impact of these changing family dynamics on developmental trajectories of child internalizing symptoms over 6 years, from preschool age to pre-adolescence. Parent-child relationship quality was observed during lengthy sessions, consisting of multiple naturalistic, carefully scripted contexts. Each parent completed reports about interparental relationship satisfaction and child internalizing symptoms. To the extent that mothers experienced a steeper decline in interparental relationship satisfaction over time, children developed internalizing symptoms at a faster rate. Further, symptoms escalated at a faster rate to the extent that negative mother-child relationship quality increased (more negative affect expressed by both mother and child, greater maternal power assertion) and positive mother-child relationship quality decreased (less positive affect expressed by both mother and child, less warmth and positive reciprocity). Time-lagged growth curve analyses established temporal precedence such that decline in family relationships preceded escalation in child internalizing symptoms. Results suggest that family dysfunction, across multiple subsystems, represents a driving force in the progression of child internalizing symptoms.

Habituation of parasympathetic-mediated heart rate responses to recurring acoustic startle

Startle habituation is a type of implicit and automatic emotion regulation. Diminished startle habituation is linked to several psychiatric or neurological disorders. Most previous studies quantified startle habituation by assessing skin conductance response (SCR; reflecting sympathetic-mediated sweating), eye-blink reflex, or motor response. The habituation of parasympathetic-mediated heart rate responses to recurrent startle stimuli is not well understood. A variety of methods and metrics have been used to quantify parasympathetic activity and its effects on the heart. We hypothesized that these different measures reflect unique psychological and physiological processes that may habituate differently during repeated startle stimuli. We measured cardiac inter-beat intervals (IBIs) to recurring acoustic startle probes in 75 eight year old children. Eight acoustic stimuli of 500 ms duration were introduced at intervals of 15-25 s. Indices of parasympathetic effect included: (1) the initial rapid decrease in IBI post-startle mediated by parasympathetic inhibition (PI); (2) the subsequent IBI recovery mediated by parasympathetic reactivation (PR); (3) rapid, beat-to-beat heart rate variability (HRV) measured from the first seven IBIs following each startle probe. SCR and motor responses to startle were also measured. Results showed that habituation of PR (IBI recovery and overshoot) and SCRs were rapid and robust. In addition, changes in PR and SCR were significantly correlated. In contrast, habituation of PI (the initial decrease in IBI) was slower and relatively modest. Measurement of rapid HRV provided an index reflecting the combination of PI and PR. We conclude that different measures of parasympathetic-mediated heart rate responses to repeated startle probes habituate in a differential manner.

Physiological reactivity moderates the association between parental directing and young adolescent friendship adjustment

This study examined whether the longitudinal association between parental directing of friendships (i.e., encouraging or discouraging certain friendships) and young adolescents' friendship adjustment (i.e., friendship quality and friends' positive characteristics) was moderated by skin conductance level reactivity (SCLR) to peer stress. Participants included 123 young adolescents (M age = 12.03 years at Time [T]1; 50% boys; 58.5% European Americans). At T1 (summer before the transition to middle school), parents reported on the extent to which they directed adolescents toward or away from certain peers, and adolescents' SCLR was assessed during a lab-based peer evaluation task. At T1 and T2 (spring of the first year of middle school), adolescents reported on the quality of their friendships and positive peer affiliations. Controlling for T1 friendship adjustment, parental directing predicted higher friendship quality and more positive peer affiliations, but only among young adolescents with lower SCLR, which was conceptualized as a marker of underarousal and insensitivity to stress. Results are discussed with reference to the developmental period of early adolescence and related research on interactions between parental control and child characteristics as predictors of adolescent adjustment.
