Growth in temperament and parenting as predictors of adjustment during children's transition to adolescence

Bushmeat trade consequences predict higher anxiety, restraint, and dominance in chimpanzees

More data are needed for a better understanding of the long-term influence of wider and combined stressful events in chimpanzee personality development. We evaluated the effects of bushmeat trade outcomes on the personality development in 84 African sanctuary chimpanzees. The chimpanzees presented different backgrounds regarding maternal care, social exposure, and abuse. We evaluated personality traits in chimpanzees using the Cattell 16PF personality questionnaire, the first application of this questionnaire in this species. We found that chimpanzees were rated as higher in anxiety after long social deprivation during infancy and juvenility, and if high human exposure was experienced. Mother-reared chimpanzees were rated as lower in restraint than hand-reared chimpanzees. Finally, mother-reared chimpanzees were rated as less dominant than hand-reared chimpanzees and rated higher when they had experienced severe mistreatment. Results suggest a wide range of possible stressful events could be potentially shaping rescued chimpanzees' personality and demonstrating the detrimental outcomes and consequences of the bushmeat and pet trade.

The Interaction Between Child Behavioral Inhibition and Parenting Behaviors: Effects on Internalizing and Externalizing Symptomology

Both child temperament and parenting have been extensively researched as predictors of child outcomes. However, theoretical models suggest that specific combinations of temperament styles and parenting behaviors are better predictors of certain child outcomes such as internalizing and externalizing symptoms than either temperament or parenting alone. The current qualitative review examines the interaction between one childhood temperamental characteristic (child behavioral inhibition) and parenting behaviors, and their subsequent impact on child psychopathology. Specifically, the moderating role of parenting on the relationship between child behavioral inhibition and both internalizing and externalizing psychopathology is examined, and the methodological variations which may contribute to inconsistent findings are explored. Additionally, support for the bidirectional relations between behavioral inhibition and parenting behaviors, as well as for the moderating role of temperament on the relationships between parenting and child outcomes, is briefly discussed. Finally, the clinical applicability of this overall conceptual model, specifically in regard to future research directions and potential clinical interventions, is considered.

The role of effortful control in the development of ADHD, ODD, and CD symptoms

Many adolescents have difficulty regulating their impulses and become prone to externalizing problems (e.g., attention-deficit/hyperactivity disorder [ADHD], oppositional defiant disorder [ODD], and conduct disorder [CD]) and other adverse consequences. Using multimethod data from a longitudinal study of Mexican-origin youth (N = 674), assessed annually from age 10 to 16, we examined the relations between effortful control and ADHD, ODD, and CD symptoms over time. Bivariate latent growth curve models showed negative correlations between the trajectories of effortful control and ADHD, ODD, and CD, indicating that steeper decreases in effortful control were related to steeper increases in ADHD, ODD, and CD symptoms. Using a novel statistical technique, the factor of curves model (FOCUS), we found that ADHD, ODD, and CD share a common "externalizing" trajectory during adolescence. Although effortful control was strongly associated with this common trajectory, it had few unique associations with the individual disorder trajectories, above and beyond their shared trajectory. When we extended the FOCUS model to include the effortful control trajectory as an indicator, we found that ADHD and ODD had strong loadings, whereas effortful control and CD had comparatively weak loadings on the shared developmental trajectory. Follow-up analyses showed that a two-factor solution, with externalizing symptom trajectories on one factor and the effortful control facet trajectories on a separate factor, was a better fit to the data than a one-factor solution. Finally, parent ASPD symptoms were related to increases in CD, but had no significant influence on effortful control, ADHD, or ODD. We discuss the implications for personality and externalizing problem development. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Transactional associations of maternal depressive symptoms with child externalizing behaviors are small after age 3

A large and growing body of research suggests that maternal depressive symptoms and child externalizing behaviors are strongly associated. Theoretical arguments supported by these findings led to the question of whether maternal depressive symptoms are transactionally associated with child externalizing behaviors. Using 5-year nationally representative longitudinal data from Turkey (N = 1,052), we estimated a transactional bivariate autoregressive latent trajectory model addressing this question. This model disaggregated the association of the two processes into two components: (a) the association of the interindividual differences in the trajectories; and (b) the intradyad association of the changes in maternal depressive symptoms with the changes in child externalizing behaviors. Although maternal depressive symptoms were robustly associated with child externalizing behaviors at age 3, the transactional associations of the two processes were small prior to age 5 and absent at ages 5 to 7. Furthermore, maternal harsh parenting did not have a mediating role in the limited transactional association of maternal depressive symptoms with child externalizing behaviors.

The codevelopment of effortful control and school behavioral problems

Effortful control refers to the propensity to regulate one's impulses and behaviors, to focus and shift attention easily, and to motivate the self toward a goal when there are competing desires. Although it seems likely that these capacities are relevant to successful functioning in the school context, there has been surprisingly little longitudinal research examining whether youth with poor effortful control are more likely to act out in the classroom, get suspended, and skip school. Conversely, there is even less research on whether youth who exhibit these school behavioral problems are more likely to decline over time in effortful control. We used multimethod data from a longitudinal study of Mexican-origin youth (N = 674), assessed biennially from 5th to 11th grade, to examine the codevelopment of effortful control and school behavioral problems. Bivariate latent growth curve models revealed a negative association between the trajectories of effortful control and school behavioral problems, indicating that steeper decreases in effortful control were related to steeper increases in school behavioral problems. Furthermore, this codevelopmental pattern was bidirectional; cross-lagged regression analyses showed that low effortful control was associated with relative increases in school behavioral problems, and school behavioral problems were associated with relative decreases in effortful control. Gender, nativity status, Mexican cultural values, and school-level antisocial behavior had concurrent associations with effortful control and school behavioral problems, but they did not moderate the codevelopmental pathways. We discuss the theoretical implications for personality development, as well as the practical implications for reducing school behavioral problems during adolescence.

Contributions of mothers' and fathers' parenting to children's self-regulation: Evidence from an adoption study

The origins of top-down self-regulation are attributed to genetic and socialization factors as evidenced by high heritability estimates from twin studies and the influential role of parenting. However, recent evidence suggests that parenting behavior itself is affected by parents' own top-down self-regulation. Because children's top-down self-regulation is influenced by genetic factors and parenting is influenced by top-down self-regulation, the effects of parenting on children's top-down self-regulation identified in prior studies may partially reflect passive gene-environment correlation. The goal of this study was to examine parenting influences on children's top-down self-regulation using a longitudinal, adoption-at-birth design, a method of identifying parenting influences that are independent of the role of shared genetic influences on children's characteristics because adoptive parents are genetically unrelated to their adopted child. Participants (N = 361) included adoptive families and biological mothers of adopted children. Adoptive mothers' and fathers' harsh/negative parenting were assessed when children were 27 months of age and biological mothers' top-down self-regulation was assessed when children were 54 months of age. Adopted children's top-down self-regulation was assessed when they were 54 and 72 months of age. Results, accounting for child gender, biological mother top-down self-regulation, and the potential evocative effects of adopted child anger, provide evidence that inherited influences and socialization processes uniquely contribute to children's top-down self-regulation. Furthermore, findings demonstrate the importance of both mother's and father's parenting behavior as an influence on young children's top-down self-regulation. The implications of these findings for understanding the complex mechanisms that influence children's top-down self-regulation are discussed.

Longitudinal Relations of Economic Hardship and Effortful Control to Active Coping in Latino Youth

How Latino youth cope with stressors may have implications for their adjustment. We examined how a temperamental characteristic (effortful control) and a contextual factor (economic hardship) were associated with Latino youth's coping. Individual differences in effortful control, a core facet of self-regulation, may contribute to coping as effortful control is consistently linked to adaptive behaviors during adolescence. We examined relations of effortful control and economic hardship to active coping in a sample of Mexican-origin youth (N = 674) across three time points (fifth to ninth grades). Although economic hardship negatively predicted coping and effortful control, effortful control positively predicted coping (controlling for prior levels). Findings support a resilience perspective by suggesting that effortful control may contribute to coping and thus counteract the negative effects of economic hardship.

Maternal Responsiveness Protects Exuberant Toddlers from Experiencing Behavior Problems in Kindergarten

RESEARCH FINDINGS

Exuberant temperament, characterized by high approach and positive affect, is linked to socioemotional outcomes including risk for externalizing symptoms across development. Externalizing problems interfere with children's school readiness and lead to disruptive behavior in the classroom. While some moderating factors help identify which exuberant children are at risk and in which contexts they are at risk, few studies have identified early moderators that protect against maladjustment when children enter school. In the current study, we examined exuberant temperament in 124 toddlers and classroom behavior problems reported by kindergarten teachers. We also assessed the impact of maternal responsiveness at 24 months on the relation between exuberance and classroom behavior problems. As hypothesized, we found that higher exuberance predicted more behavior problems. Additionally, maternal responsiveness moderated this association such that high responsiveness protected exuberant children from classroom behavior problems.

PRACTICE OR POLICY

These results expand our understanding of socioemotional risks for exuberant children and how these risks influence school readiness. We also find that maternal responsiveness during toddlerhood mitigates these risks, and our findings suggest that interventions for exuberant children at risk for behavior problems or poor school readiness should target parental responsiveness when children are toddlers.

Stress Reactivity as a Pathway from Attentional Control Deficits in Everyday Life to Depressive Symptoms in Adolescent Girls

The goal of this research was to expand theoretical models of adolescent depression to determine whether individual differences in cognitive processing-specifically attentional control deficits-help to explain increased risk for depression during adolescence. We also examined whether this pathway was stronger in girls than in boys. A longitudinal design was used to examine whether poor attentional control in everyday life (i.e., difficulties shifting between ideas, tasks, and activities) contributes to depression over time by fostering higher levels of stress reactivity. Youth (298 boys, 338 girls) completed questionnaires assessing stress reactivity (6th and 7th grades) and depressive symptoms (6th, 7th and, 8th grades); teachers completed the shifting subscale of the Behavior Rating Scale of Executive Function (Gioia et al. 2000a) to assess attentional control (6th and 7th grades). Structural equation modeling analyses provided support for the predicted pathway in girls but not boys, yielding a significant indirect effect from 6th grade shifting deficits to 8th grade depressive symptoms via 7th grade stress reactivity. These results suggest that attentional control deficits in early adolescence heighten girls' sensitivity to stress and consequent depressive symptoms, providing a critical direction for efforts to decrease adolescent girls' risk for depression.

Personality development in the context of individual traits and parenting dynamics

Our conceptualization of adult personality and childhood temperament can be closely aligned in that they both reflect endogenous, likely constitutional dispositions. Empirical studies of temperament have focused on measuring systematic differences in emotional reactions, motor responses, and physiological states that we believe may contribute to the underlying biological components of personality. Although this work has provided some insight into the early origins of personality, we still lack a cohesive developmental account of how personality profiles emerge from infancy into adulthood. We believe the moderating impact of context could shed some light on this complex trajectory. We begin this article reviewing how researchers conceptualize personality today, particularly traits that emerge from the Five Factor Theory (FFT) of personality. From the temperament literature, we review variation in temperamental reactivity and regulation as potential underlying forces of personality development. Finally, we integrate parenting as a developmental context, reviewing empirical findings that highlight its important role in moderating continuity and change from temperament to personality traits.

Bidirectional association between effortful control and intentional self-regulation and their integrative effect on deviant adolescent behaviors

Effortful control and intentional self-regulation are two constructs associated with children’s and adolescent self-regulation that have historically been the subject of research in separate fields, where temperament research has primarily focused on effortful control, and positive development research has focused on intentional self-regulation. This study examines the reciprocal relationship between effortful control and intentional self-regulation and discusses how they relate to deviant adolescent behaviors. A total of 599 adolescents from western Taiwan participated in this study, and four waves of data were collected in 2 years. Cross-lagged structural equation models were tested. The results indicate that effortful control has a predominant influence on intentional self-regulation; also, effortful control negatively predicts deviant behavior for boys, whereas intentional self-regulation displays a similar effect for girls.

Latent profile and cluster analysis of infant temperament: Comparisons across person-centered approaches

There is renewed interest in person-centered approaches to understanding the structure of temperament. However, questions concerning temperament types are not frequently framed in a developmental context, especially during infancy. In addition, the most common person-centered techniques, cluster analysis (CA) and latent profile analysis (LPA), have not been compared with respect to derived temperament types. To address these gaps, we set out to identify temperament types for younger and older infants, comparing LPA and CA techniques. Multiple data sets (N = 1,356; 672 girls, 677 boys) with maternal ratings of infant temperament obtained using the Infant Behavior Questionnaire-Revised (Gartstein & Rothbart, 2003) were combined. All infants were between 3 and 12 months of age (M = 7.85; SD = 3.00). Due to rapid development in the first year of life, LPA and CA were performed separately for younger (n = 731; 3 to 8 months of age) and older (n = 625; 9 to 12 months of age) infants. Results supported 3-profile/cluster solutions as optimal for younger infants, and 5-profile/cluster solutions for the older subsample, indicating considerable differences between early/mid and late infancy. LPA and CA solutions produced relatively comparable types for younger and older infants. Results are discussed in the context of developmental changes unique to the end of the first year of life, which likely account for the present findings. (PsycINFO Database Record

The interplay of maternal sensitivity and gentle control when predicting children's subsequent academic functioning: Evidence of mediation by effortful control

The goal of this work was to examine the complex interrelation of mothers' early gentle control and sensitivity in predicting children's effortful control (EC) and academic functioning. Maternal gentle control, maternal sensitivity, and children's EC were measured when children were 18, 30, and 42 months of age (T1, T2, and T3, respectively), and measures of children's academic functioning were combined across 72 and 84 months (T5/T6; Ns = 255, 222, 200, 162, and 143). Using structural equation modeling, results demonstrated that T1 maternal sensitivity moderated the relation between T1 maternal gentle control and T2 EC, and T3 EC predicted children's later academic functioning. There was evidence for moderated mediation, such that when maternal sensitivity was high, children's EC mediated the relation between T1 maternal gentle control and children's academic functioning, even after controlling for stability of the constructs. The relation between maternal gentle control and children's EC was not significant under conditions of low maternal sensitivity. Implications for parenting programs are offered and future research directions are discussed. (PsycINFO Database Record

Parental educational attainment and adult offspring personality: An intergenerational life span approach to the origin of adult personality traits

Why do some individuals have more self-control or are more vulnerable to stress than others? Where do these basic personality traits come from? Although a fundamental question in personality, more is known about how traits are related to important life outcomes than their developmental origins. The present research took an intergenerational life span approach to address whether a significant aspect of the childhood environment-parental educational attainment-was associated with offspring personality traits in adulthood. We tested the association between parents' educational levels and adult offspring personality traits in 7 samples (overall age range 14-95) and meta-analytically combined the results (total N > 60,000). Parents with more years of education had children who were more open, extraverted, and emotionally stable as adults. These associations were small but consistent, of similar modest magnitude to the association between life events and change in personality in adulthood, and were also supported by longitudinal analyses. Contrary to expectations, parental educational attainment was unrelated to offspring Conscientiousness, except for a surprisingly negative association in the younger cohorts. The results were similar in a subsample of participants who were adopted, which suggested that environmental mechanisms were as relevant as shared genetic variants. Participant levels of education were associated with greater conscientiousness, emotional stability, extraversion, and openness and partially mediated the relation between parent education and personality. Child IQ and family income were also partial mediators. The results of this research suggest that parental educational attainment is 1 intergenerational factor associated with offspring personality development in adulthood. (PsycINFO Database Record

Associations Between Parenting Styles and Perceived Child Effortful Control Within Chinese Families in the United States, the United Kingdom, and Taiwan

The current study examined the associations between parentally perceived child effortful control (EC) and the parenting styles of 122 Chinese mothers (36 first-generation Chinese immigrants in the United Kingdom, 40 first-generation Chinese immigrants in the United States, and 46 Taiwanese mothers) of 5- to 7-year-old (M age = 5.82 years, SD = .805; 68 boys and 54 girls) children. The findings showed significant cultural group differences in mothers' reported authoritarian parenting style. Significant associations also emerged between mothers' reports of their children's EC and some parenting dimensions, although there were no cultural group differences in perceived child EC. Different patterns of associations between perceived child EC and parenting styles in these three groups also demonstrated heterogeneity within the Chinese population, and highlighted the need to consider differences between original and receiving societies when seeking to understand parenting and child development in different immigrant groups.

The Relations Between Parental Socioeconomic Status, Personality, and Life Outcomes

Studies have shown that cognitive ability is correlated with parental socioeconomic status (pSES). However, little is known about the correlation between personality and pSES. To better understand this relation, we conducted a meta-analysis of the correlations between pSES and personality traits and temperament dimensions. The correlations were generally very small with the exception of the correlation between pSES and openness to experience. Our results were replicated in a large ( N = 2,183,377) data set of self-reported personality scores collected online. Using this data set, we also examined the interaction between pSES and personality on attained education and socioeconomic status. We found evidence for the resource substitution hypothesis, which proposes that personality compensates for background disadvantage.

Roles of Response Inhibition and Gene-Environment Interplay in Pathways to Adolescents' Externalizing Problems

This study used two waves of data to investigate pathways through which adolescents' response inhibition related to later externalizing problems. A polygenic risk score indexed genetic risk for poor response inhibition. Adolescents' performance on a response inhibition task mediated the relation between adolescents' polygenic risk scores and mother's inconsistent parenting (i.e., evocative rGE), even after controlling for mothers' genetic risk (i.e., passive rGE). Mothers' inconsistent parenting subsequently prospectively predicted adolescents' externalizing problems. Adolescents' response inhibition also prospectively predicted later externalizing behaviors. These findings were subgroup-specific, with greater risk for non-Hispanic Caucasian boys with substance-disordered parents. Results suggest that poor response inhibition may increase risk for adolescents' externalizing problems both directly and by evoking certain environmental conditions.

The Relationship Between Father Involvement and Child Problem Behaviour in Intact Families: A 7-Year Cross-Lagged Study

This study investigated the cross-lagged relationship between father involvement and child problem behaviour across early-to-middle childhood, and tested whether temperament modulated any cross-lagged child behaviour effects on father involvement. It used data from the first four waves of the UK's Millennium Cohort Study, when children (50.3 % male) were aged 9 months, and 3, 5 and 7 years. The sample was 8302 families where both biological parents were co-resident across the four waves. Father involvement (participation in play and physical and educational activities with the child) was measured at ages 3, 5 and 7, as was child problem behaviour (assessed with the Strengths and Difficulties Questionnaire). Key child and family covariates related to father involvement and child problem behaviour were controlled. Little evidence was found that more father involvement predicted less child problem behaviour two years later, with the exception of father involvement at child's age 5 having a significant, but small, effect on peer problems at age 7. There were two child effects. More hyperactive children at age 3 had more involved fathers at age 5, and children with more conduct problems at age 3 had more involved fathers at age 5. Child temperament did not moderate any child behaviour effects on father involvement. Thus, in young, intact UK families, child adjustment appears to predict, rather than be predicted by, father involvement in early childhood. When children showed more problematic behaviours, fathers did not become less involved. In fact, early hyperactivity and conduct problems in children seemed to elicit more involvement from fathers. At school age, father involvement appeared to affect children's social adjustment rather than vice versa.

Environmental adversity and children's early trajectories of problem behavior: The role of harsh parental discipline

This study was performed to examine the role of harsh parental discipline in mediating and moderating the effects of environmental adversity (family socioeconomic disadvantage and adverse life events) on emotional and behavioral problems across early-to-middle childhood. The sample included 16,916 children (48% female; 24% non-White) from the U.K.'s Millennium Cohort Study. We analyzed trajectories of conduct, hyperactivity, and emotional problems, measured at ages 3, 5, and 7 years, using growth curve models. Harsh parental discipline was measured at these ages with parent-reported items on the frequency of using the physical and verbal discipline tactics of smacking, shouting at, and "telling off" the child. As expected, family socioeconomic disadvantage and adverse life events were significantly associated with emotional and behavioral problems. Harsh parental discipline was related to children's trajectories of problems, and it moderated, but did not explain, the effect of environmental risk on these trajectories. High-risk children experiencing harsh parental discipline had the highest levels of conduct problems and hyperactivity across the study period. In addition, harsh parental discipline predicted an increase in emotional symptoms over time in high-risk children, unseen in their counterparts experiencing low levels of harsh parental discipline. However, children in low-risk families were also negatively affected by harsh parental discipline concurrently and over time. In conclusion, harsh parental discipline predicted emotional and behavioral problems in high- and low-risk children and moderated the effects of family poverty and adversity on these problems.

Heart rate variability indices as bio-markers of top-down self-regulatory mechanisms: A meta-analytic review

Theoretical perspectives posit that heart-rate variability (HRV) reflects self-regulatory capacity and therefore can be employed as a bio-marker of top-down self-regulation (the ability to regulate behavioral, cognitive, and emotional processes). However, existing findings of relations between self-regulation and HRV indices are mixed. To clarify the nature of such relations, we conducted a meta-analysis of 123 studies (N=14,347) reporting relations between HRV indices and aspects of top-down self-regulation (e.g., executive functioning, emotion regulation, effortful control). A significant, albeit small, effect was observed (r=0.09) such that greater HRV was related to better top-down self-regulation. Differences in relations were negligible across aspects of self-regulation, self-regulation measurement methods, HRV computational techniques, at-risk compared with healthy samples, and the context of HRV measurement. Stronger relations were observed in older relative to younger samples and in published compared to unpublished studies. These findings generally support the notion that HRV indices can tentatively be employed as bio-markers of top-down self-regulation. Conceptual and theoretical implications, and critical gaps in current knowledge to be addressed by future work, are discussed.

Intergenerational Transmission of Maladaptive Parenting Strategies in Families of Adolescent Mothers: Effects from Grandmothers to Young Children

The current longitudinal study examined the effect of the transmission of maladaptive parenting strategies from grandmothers to adolescent mothers on children's subsequent development. Mexican-origin adolescent mothers (N = 204) participated in home interviews when the adolescent's child (89 boys, 60 girls) was 2, 3, 4, and 5 years old. Grandmothers' psychological control toward the adolescent mother was positively related to adolescents' potential for abuse 1 year later, which was subsequently positively related to adolescents' punitive discipline toward their young child. In addition, adolescent mothers' punitive discipline subsequently predicted greater externalizing problems and less committed compliance among their children. Adolescent mothers' potential for abuse and punitive discipline mediated the effects of grandmothers' psychological control on children's externalizing problems. Finally, adolescent mothers' potential for abuse mediated the effect of grandmothers' psychological control on adolescent mothers' punitive discipline. Results highlight the salience of long-term intergenerational effects of maladaptive parenting on children's behavior.

Bidirectional Relations Between Temperament and Parenting Predicting Preschool-Age Children's Adjustment

Bidirectional associations between child temperament (fear, frustration, positive affect, effortful control) and parenting behaviors (warmth, negativity, limit setting, scaffolding, responsiveness) were examined as predictors of preschool-age children's adjustment problems and social competence. Participants were a community sample of children (N = 306; 50% female, 64% European American) and their mothers. Observational measures of child temperament and parenting were obtained using laboratory tasks at two time points (children's ages 36 and 54 months). Teacher-reported adjustment measures were collected at the first and third time points (children's ages 36 and 63 months). Cross-lagged analyses were performed to examine whether child temperament and parenting predict changes in one another, whether they each contribute independently to children's adjustment, and whether these transactional relations account for adjustment outcomes. Maternal negativity at 36 months predicted increases in child frustration at 54 months. Maternal negativity and child effortful control predicted decreases in each other from 36 to 54 months. Maternal warmth predicted increases in child effortful control over time. Child frustration, child effortful control, maternal warmth, and maternal negativity at 54 months each independently predicted child adjustment problems at 63 months, controlling for problems at 36 months. Child executive control at 54 months predicted increases in child social competence at 63 months. The findings suggest that temperament and parenting have independent and additive effects on preschool-age child adjustment, with some support for a bidirectional relation.

Family instability and children's effortful control in the context of poverty: Sometimes a bird in the hand is worth two in the bush

Effortful control has been demonstrated to have important ramifications for children's self-regulation and social-emotional adjustment. However, there are wide socioeconomic disparities in children's effortful control, with impoverished children displaying heightened difficulties. The current study was designed to demonstrate how instability within the proximal rearing context of young children may serve as a key operant on the development of children's effortful control in the context of poverty. Two separate studies were conducted that included samples of children living within homes characterized by heightened economic risk. In Study 1, we tested the differential prediction of family instability on two domains of children's effortful control: cool effortful control and delay control. Consistent with hypotheses, elevated instability was associated with decreased hot effortful control but not cool effortful control over the span of 2 years. In Study 2, we examined how children's basal cortisol activity may account for associations between heightened instability and effortful control in reward tasks. The results were consistent with sensitization models, suggesting that elevated cortisol activity arising from increased uncertainty and unpredictability in rearing contexts may influence children's hot effortful control. The findings are interpreted within emerging evolutionary-developmental frameworks of child development.

A longitudinal study of self-control at the transition to secondary school: Considering the role of pubertal status and parenting

Higher self-control in children and adolescents is associated with a range of positive outcomes in adulthood. However, little is known about the naturalistic development of self-control during early adolescence and the factors that affect this. We examined the role of puberty and parenting style as theoretically important influences on stability and change in self-control. A longitudinal (3 waves), multiple-informant dataset of children entering early adolescence (M = 11 years) was used to explore longitudinal change in self-control using latent growth curve modelling. Children's self-control declined during the one-year study period and declines were associated with children's behavioural and social functioning. Associations with self-control were found for pubertal status and parental warmth and hostility, but not for parental discipline. The findings suggest that during early adolescence, when children make the transition to secondary school, self-control declines. This is particularly the case for those experiencing puberty earlier than their peers. Parent warmth influences the trajectory of self-control during this period.

The Emergence of Parent-Child Coercive Processes in Toddlerhood

Parent-child coercion typically emerges in toddlerhood with the child's first acts of willful defiance and the parent's first disciplinary attempts. We explored how parents and children may contribute to this process by examining bidirectional and interactive effects between child and maternal negative behavior in 310 low-income, ethnically diverse boys. Using multiple informants and methods, child negative emotionality and maternal negative control were assessed at 18 months and child disruptive behavior and maternal negative control were measured at 24 months. Indicative of parent effects, maternal negative control at 18 months amplified the relation between children's negative emotionality at 18 months and disruptive behavior at 24 months. Child effects were found in an unexpected direction such that children's negative emotionality at 18 months predicted decreases in mothers' negative control at 24 months. Findings are discussed within a transactional framework that emphasizes mutual influence of children and parents over the course of development.

Variable- and Person-Centered Approaches to Examining Temperament Vulnerability and Resilience to the Effects of Contextual Risk

Using both variable- and person-centered approaches, this study examined the role of temperament in relation to children's vulnerable or resilient responses to cumulative risk. Observed reactivity and regulation dimensions of temperament were tested as mediating and moderating the relation between family cumulative risk and teacher-reported adjustment problems in a sample of 259 preschool-age children. Further, latent profile analyses were used to examine whether profiles of temperament, accounting for multiple characteristics simultaneously, provided additional information about the role of temperament in children's responses to risk. Results support a diathesis-stress model in which high frustration, low fear, and low delay ability confer particular vulnerability for children in high-risk contexts. Benefits of multiple approaches are highlighted.

A Developmental Psychopathology Perspective on ADHD and Comorbid Conditions: The Role of Emotion Regulation

Research investigating attention-deficit/hyperactivity disorder (ADHD) and co-occurring disorders such as oppositional defiant disorder, conduct disorder, anxiety, and depression has surged in popularity; however, the developmental relations between ADHD and these comorbid conditions remain poorly understood. The current paper uses a developmental psychopathology perspective to examine conditions commonly comorbid with ADHD during late childhood through adolescence. First, we present evidence for ADHD and comorbid disorders. Next, we discuss emotion regulation and its associations with ADHD. The role of parenting behaviors in the development and maintenance of emotion regulation difficulties and comorbid disorders among children with ADHD is explored. An illustrative example of emotion regulation and parenting over the course of development is provided to demonstrate bidirectional relations among these constructs. We then present an integrated conceptual model of emotion regulation as a shared risk process that may lead to different comorbid conditions among children with ADHD. Implications and directions for future research are presented.

Early Parenting and the Development of Externalizing Behavior Problems: Longitudinal Mediation Through Children's Executive Function

Path analysis was used to investigate the longitudinal associations among parenting and children's executive function and externalizing behavior problems from 36 to 90 months of age in the Family Life Project (N = 1,115), a study of child development in the context of rural poverty. While controlling for stability in the constructs, semistructured observations of parenting prospectively predicted performance on a battery of executive function tasks and primary caregivers' reports of externalizing behavior. Furthermore, the association between early parenting and later externalizing behavior was longitudinally mediated by executive function, providing support for a process model in which sensitive parenting promotes children's self-regulation, which in turn reduces children's externalizing behavior.

Contribution of temperament to eating disorder symptoms in emerging adulthood: Additive and interactive effects

Temperament characteristics, such as higher negative emotionality (NE) and lower effortful control (EC), are individual difference risk factors for developmental psychopathology. Research has also noted relations between temperament and more specific manifestations of psychopathology, such as eating disorders (EDs). Although work is emerging that indicates that NE and EC may additively contribute to risk for ED symptoms, no studies have considered the interactive effects of NE and EC in relation to ED symptoms. In the current investigation, we hypothesized that (1) low EC would be associated with increased ED symptoms, (2) high NE would be associated with increased ED symptoms, and (3) these temperament traits would interact, such that the relationship between NE and ED symptoms would be strongest in the presence of low EC. After controlling for gender and child trauma history, emerging adults' (N=160) lower EC (i.e., more difficulties with self-regulation) was associated with more ED symptoms. NE did not emerge as a direct predictor of ED symptoms. However, the anticipated interaction of these temperament characteristics on ED symptoms was found. The association between NE and ED symptoms was only significant in the context of low EC. These findings provide evidence that elevated NE may only be a risk factor for the development of eating disorders when individuals also have self-regulation difficulties. The implications of these findings for research and interventions are discussed.

Observed emotion frequency versus intensity as predictors of socioemotional maladjustment

The purpose of this study was to assess whether observed emotional frequency (the proportion of instances an emotion was observed) and intensity (the strength of an emotion when it was observed) uniquely predicted kindergartners' (N = 301) internalizing and externalizing problems. Analyses were tested in a structural equation modeling (SEM) framework with data from multireporters (reports of problem behaviors from teachers and parents) and naturalistic observations of emotion in the fall semester. For observed positive emotion, both frequency and intensity negatively predicted parent- or teacher-reported internalizing symptoms. Anger frequency positively predicted parent- and teacher-reported externalizing symptoms, whereas anger intensity positively predicted parent- and teacher-reported externalizing and parent-reported internalizing symptoms. The findings support the importance of examining both aspects of emotion when predicting maladjustment.

School climate and delinquency among Chinese adolescents: analyses of effortful control as a moderator and deviant peer affiliation as a mediator

School climate is the quality and character of school life and reflects the norms, goals, values, interpersonal relationships, teaching and learning practices, and the organizational structure of a school. There is substantial literature documenting the negative association between positive school climate and adolescent delinquency, but little is known about the moderating and mediating mechanisms underlying this relationship. The aim of this study was to examine whether the direct and indirect pathways between school climate and adolescent delinquency would be moderated by effortful control. A sample of 2,758 Chinese adolescents (M age = 13.53 years, SD = 1.06) from 10 middle schools completed anonymous questionnaires regarding school climate, effortful control, deviant peer affiliation, and delinquency. After gender, age, geographical area, and socioeconomic status were included as covariates, the results revealed that school climate was significantly associated with adolescent delinquent behavior. This direct association was moderated by effortful control, such that the negative relationship between positive school climate and delinquency was only significant among adolescents low in effortful control. Moreover, the indirect association between school climate and delinquency via deviant peer affiliation was also moderated by effortful control. Specifically, the moderating effect of effortful control was not only manifested in the relationship between school climate and deviant peer affiliation, but also in the relationship between deviant peer affiliation and delinquency. These findings contribute to understanding the mechanisms through which positive school climate might reduce delinquent behavior and have important implications for prevention efforts aimed at diminishing adolescent delinquency.

Interactive Contributions of Cumulative Peer Stress and Executive Function Deficits to Depression in Early Adolescence

Exposure to peer stress contributes to adolescent depression, yet not all youth experience these effects. Thus, it is important to identify individual differences that shape the consequences of peer stress. This research investigated the interactive contribution of cumulative peer stress during childhood (second-fifth grades) and executive function (EF) deficits to depression during early adolescence (sixth grade). Youth (267 girls, 227 boys; X̄age at Wave 1 = 7.95, SD = .37) completed questionnaires and semi-structured interviews to assess peer stress and depression, respectively; teachers completed the Behavior Rating Scale of Executive Function to assess everyday performance in several EF domains. As anticipated, exposure to peer stress in childhood predicted heightened sixth-grade depression in girls but not boys with higher levels of EF deficits. This study extends theory and research on individual differences in vulnerability to adolescent depression, in turn elucidating potential intervention targets.

Parenting Behaviors and Anxiety in Young Adults

Parenting behaviors – specifically behaviors characterized by high control, intrusiveness, rejection, and overprotection – and effortful control have each been implicated in the development of anxiety pathology. However, little research has examined the protective role of effortful control in the relation between parenting and anxiety symptoms, specifically among adults. Thus, we sought to explore the unique and interactive effects of parenting and effortful control on anxiety among adults (N = 162). Results suggest that effortful control uniquely contributes to anxiety symptoms above and beyond that of any parenting behavior. Furthermore, effortful control acted as a moderator of the relationship between parental overprotection and anxiety, such that overprotection is associated with anxiety only in individuals with lower levels of effortful control. Implications for potential prevention and intervention efforts which specifically target effortful control are discussed. These findings underscore the importance of considering individual differences in self-regulatory abilities when examining associations between putative early-life risk factors, such as parenting, and anxiety symptoms.

The role of temperament by family environment interactions in child maladjustment

In order to advance our understanding of the etiology of individual differences in child maladjustment (i.e., conduct and emotional problems), we tested hypotheses about the statistical interactions between child temperament and two aspects of the family environment: maternal negativity and positivity, and household chaos (e.g., crowding, noise, lack of routines). Mothers (n = 149) reported on their child's effortful control, negative affect, surgency, and behavioral/emotional problems. The age range of the children was 3 to 7 years old and half of the sample was girls. Observers rated maternal negativity and positivity based on brief structured interaction tasks in the laboratory. Child temperament moderated the association between maternal negativity/positivity and child maladjustment. Maternal negativity and child problem behavior were associated only for those children who also were high in surgency or negative affectivity. Maternal positivity was associated with less child problem behavior for those high in surgency. Child effortful control interacted with both maternal negativity and chaos. Maternal negativity and child problem behavior were most strongly associated for children who were low in effortful control and living in chaotic homes. The results point to distinct transactions between child temperament and maternal negativity/positivity that depend in part on the dimensions of temperament and parenting behavior in question.

Intergenerational transmission of self-regulation: A multidisciplinary review and integrative conceptual framework

This review examines mechanisms contributing to the intergenerational transmission of self-regulation. To provide an integrated account of how self-regulation is transmitted across generations, we draw from over 75 years of accumulated evidence, spanning case studies to experimental approaches, in literatures covering developmental, social, and clinical psychology, and criminology, physiology, genetics, and human and animal neuroscience (among others). First, we present a taxonomy of what self-regulation is and then examine how it develops--overviews that guide the main foci of the review. Next, studies supporting an association between parent and child self-regulation are reviewed. Subsequently, literature that considers potential social mechanisms of transmission, specifically parenting behavior, interparental (i.e., marital) relationship behaviors, and broader rearing influences (e.g., household chaos) is considered. Finally, evidence that prenatal programming may be the starting point of the intergenerational transmission of self-regulation is covered, along with key findings from the behavioral and molecular genetics literatures. To integrate these literatures, we introduce the self-regulation intergenerational transmission model, a framework that brings together prenatal, social/contextual, and neurobiological mechanisms (spanning endocrine, neural, and genetic levels, including gene-environment interplay and epigenetic processes) to explain the intergenerational transmission of self-regulation. This model also incorporates potential transactional processes between generations (e.g., children's self-regulation and parent-child interaction dynamics that may affect parents' self-regulation) that further influence intergenerational processes. In pointing the way forward, we note key future directions and ways to address limitations in existing work throughout the review and in closing. We also conclude by noting several implications for intervention work.

Relations of growth in effortful control to family income, cumulative risk, and adjustment in preschool-age children

The study examined growth in effortful control (executive control, delay ability) in relation to income, cumulative risk (aggregate of demographic and psychosocial risk factors), and adjustment in 306 preschool-age children (50 % girls, 50 % boys) from families representing a range of income (29 % at- or near-poverty; 28 % lower-income; 25 % middle-income; 18 % upper-income), with 4 assessments starting at 36-40 month. Income was directly related to levels of executive control and delay ability. Cumulative risk accounted for the effects of income on delay ability but not executive control. Higher initial executive control and slope of executive control and delay ability predicted academic readiness, whereas levels, but not growth, of executive control and delay ability predicted social competence and adjustment problems. Low income is a marker for lower effortful control, which demonstrates additive or mediating effects in the relation of income to children's preschool adjustment.

Maternal borderline personality disorder symptoms and parenting of adolescent daughters

Maternal borderline personality disorder (BPD) symptoms are associated with poorer parenting. However, most studies conducted are with young children. In the current study, the authors examined associations between maternal BPD symptoms and parenting in an urban community sample of 15-to 17-year-old girls (n = 1,598) and their biological mothers. Additionally, the authors tested the impact of adolescent temperament on these associations. Mothers reported on their own psychopathology and their daughters' temperament. Adolescent girls reported on mothers' parenting methods in terms of psychological and behavioral control. Results demonstrated that maternal BPD symptoms were associated with aspects of psychological and behavioral control, even after controlling for maternal depression and alcohol use severity. After examining specific BPD components that may account for these associations, the authors found that affective/behavioral dysregulation, but not interpersonal dysregulation or identity disturbance, uniquely accounted for parenting. Adolescent temperament did not moderate these associations. BPD symptoms, particularly affective/behavioral dysregulation, are important targets when conducting parenting interventions.

A Twin Study of Problematic Internet Use: Its Heritability and Genetic Association With Effortful Control

Our goal was to estimate genetic and environmental sources of influence on adolescent problematic internet use, and whether these individual differences can be explained by effortful control, an important aspect of self-regulation. A sample of 825 pairs of Chinese adolescent twins and their parents provided reports of problematic internet use and effortful control. Univariate analysis revealed that genetic factors explained 58–66% of variance in problematic internet use, with the rest explained by non-shared environmental factors. Sex difference was found, suggesting boys’ problematic internet use was more influenced by genetic influences than girls’ problematic internet use. Bivariate analysis indicated that effortful control accounted for a modest portion of the genetic and non-shared environmental variance in problematic internet use among girls. In contrast, among boys, effortful control explained between 6% (parent report) and 20% (self-report) of variance in problematic internet use through overlapping genetic pathways. Adolescent problematic internet use is heritable, and poor effortful control can partly explain adolescent problematic internet use, with effects stronger for boys. Implications for future research are discussed.

Effects of structural and dynamic family characteristics on the development of depressive and aggressive problems during adolescence. The TRAILS study

Both structural (i.e., SES, familial psychopathology, family composition) and dynamic (i.e., parental warmth and rejection) family characteristics have been associated with aggressive and depressive problem development. However, it is unclear to what extent (changes in) dynamic family characteristics have an independent effect on problem development while accounting for stable family characteristics and comorbid problem development. This issue was addressed by studying problem development in a large community sample (N = 2,230; age 10-20) of adolescents using Linear Mixed models. Paternal and maternal warmth and rejection were assessed via the Egna Minnen Beträffande Uppfostran for Children (EMBU-C). Aggressive and depressive problems were assessed via subscales of the Youth/Adult Self-Report. Results showed that dynamic family characteristics independently affected the development of aggressive problems. Moreover, maternal rejection in preadolescence and increases in paternal rejection were associated with aggressive problems, whereas decreases in maternal rejection were associated with decreases in depressive problems over time. Paternal and maternal warmth in preadolescence was associated with fewer depressive problems during adolescence. Moreover, increases in paternal warmth were associated with fewer depressive problems over time. Aggressive problems were a stable predictor of depressive problems over time. Finally, those who increased in depressive problems became more aggressive during adolescence, whereas those who decreased in depressive problems became also less aggressive. Besides the effect of comorbid problems, problem development is to a large extent due to dynamic family characteristics, and in particular to changes in parental rejection, which leaves much room for parenting-based interventions.

Conscientiousness: origins in childhood?

In this review, we evaluate developmental and personality research with the aim of determining whether the personality trait of conscientiousness can be identified in children and adolescents. After concluding that conscientiousness does emerge in childhood, we discuss the developmental origins of conscientiousness with a specific focus on self-regulation, academic motivation, and internalized compliance/internalization of standards. On the basis of the accumulated body of evidence, we conclude that self-regulation fosters conscientiousness later in life, both directly and via academic motivation and internalized compliance with norms. We argue that elements of conscientiousness are evident by early childhood; self-regulation skills are likely a core developmental component of conscientiousness; and despite the contribution of heredity to the aforementioned aspects of functioning, environmental factors likely contribute to conscientiousness.
