Differential susceptibility and the early development of aggression: interactive effects of respiratory sinus arrhythmia and environmental quality

The purpose of the current study was to predict the development of aggressive behavior from young children's respiratory sinus arrhythmia (RSA) and environmental quality. In a longitudinal sample of 213 children, baseline RSA, RSA suppression in response to a film of crying babies, and a composite measure of environmental quality (incorporating socioeconomic status and marital adjustment) were measured, and parent-reported aggression was assessed from 18 to 54 months of age. Predictions based on biological sensitivity-to-context/differential susceptibility and diathesis-stress models, as well as potential moderation by child sex, were examined. The interaction of baseline RSA with environmental quality predicted the development (slope) and 54-month intercept of mothers' reports of aggression. For girls only, the interaction between baseline RSA and environmental quality predicted the 18-month intercept of fathers' reports. In general, significant negative relations between RSA and aggression were found primarily at high levels of environmental quality. In addition, we found a significant Sex × RSA interaction predicting the slope and 54-month intercept of fathers' reports of aggression, such that RSA was negatively related to aggression for boys but not for girls. Contrary to predictions, no significant main effects or interactions were found for RSA suppression. The results provide mixed but not full support for differential susceptibility theory and provide little support for the diathesis-stress model.     

Parental behaviour and children's creation of imaginary companions: A longitudinal study

This longitudinal study examined whether parenting quality, parental behaviours and children's temperament at 6 months of age predicted children's creations of imaginary companions (ICs) at 44 months of age. At six months, parenting quality and parental behaviours were measured using the Parent-Child Early Relational Assessment, and the frequency of mental-state references made during mother–infant interactions was recorded. Temperament was assessed using the Revised Infant Temperament Questionnaire. Parents then completed questionnaires assessing whether their children had ICs at 44 months of age. The results revealed that only the approach characteristic of temperament marginally predicted children's IC status. Results of the parental measures showed that parents of children with ICs were more likely to attribute mental states to their child and to refrain from intruding in their child's behaviours than parents of children without ICs. The results indicated that parental behaviours are important for children's creation of ICs.     

Trajectories and predictors of indirect aggression: results from a nationally representative longitudinal study of Canadian children aged 2-10

The purposes of this study were to model the development of indirect aggression among a nationally representative sample of 1,401 Canadian children aged 4 at T2, 6 at T3, 8 at T4 and 10 at T5, and to examine predictors of trajectory group membership from T1 (age 2) child, familial, and parenting variables. Using a semi-parametric group-based modeling approach, two distinct trajectories were identified: "increasing users" comprising of 35% of the sample and "stable low users" comprising of 65% of the sample. Using logistic regression analyses to distinguish these two groups, we found that for girls, more frequent, increasing use of indirect aggression was associated with prior prosocial and physically aggressive behavior, low SES and low parental social support at age 2. For boys, increasing use of indirect aggression was associated with prior parenting issues at age 2-inconsistency and less positive parent-child interactions. Although this study provides unique information regarding the early development of indirect aggression and its predictors, more longitudinal research is needed to fully understand its development.     

Differential associations between maternal and paternal parenting and physical and relational aggression

A large number of studies have demonstrated that negative parenting is associated with greater levels of aggression (relational and physical) among school‐age children in Western cultures. However, the investigation of this association for children in non‐Western cultures is still in its infancy. The present study examines the associations between maternal and paternal parenting behaviours (conflict with the child, physical aggression toward the child and relational aggression toward the child) and forms of aggression, and explores gender differences in these associations among Japanese boys and girls. The participants were 130 fifth and sixth graders (age range: 10 to 12). Children reported maternal and paternal parenting behaviours, and classroom teachers assessed children's relational and physical aggression. Results show that boys and girls had more conflict, more relationally aggressive parenting experiences and more intimate relationships with their mothers than their fathers. Further, after controlling for grade and gender, greater maternal (but not paternal) relational aggression was associated with more peer‐oriented relational aggression for boys only and more peer‐oriented physical aggression for boys and girls. Greater paternal (but not maternal) conflict was predictive of more peer‐oriented physical aggression for boys and girls. The direction and strength of the associations between parenting behaviours and forms of aggression may be contingent upon the gender of the parent and the child. The findings are discussed from cultural, developmental and social perspectives, and implications for future research are discussed.     

父亲参与教养对小学生攻击行为的影响:母亲育儿压力的部分中介效应

本研究旨在考察父亲参与教养对小学生攻击行为的影响以及母亲育儿压力在二者之间的中介作用,采用同伴提名法和问卷法对604名1~6年级小学生及其家长进行调查。潜变量结构方程模型拟合检验结果显示：父亲参与教养（互动性、可及性、责任性）对小学生攻击行为（身体攻击、关系攻击）具有显著的负向预测作用;在父亲参与教养与小学生关系攻击之间,母亲的育儿愁苦和亲子互动失调具有显著的部分中介作用;在父亲参与教养与小学生身体攻击之间,只有母亲的育儿愁苦具有显著的部分中介作用。上述结果表明,父亲参与教养可以通过减少母亲的育儿愁苦来降低儿童的关系攻击和身体攻击,还能通过减少母子互动失调来降低儿童的关系攻击。     

Do Early Difficult Temperament and Harsh Parenting Differentially Predict Reactive and Proactive Aggression?

The goal of this study was to examine the links between difficult temperament (i.e., negative emotionality) and harsh parental discipline during toddlerhood, and reactive and proactive aggression in kindergarten. These links were assessed on a longitudinal population-based study of 1516 boys and girls followed longitudinally from the age of 17 months through the age of 72 months. Two possible models were tested to examine the interplay between negative emotionality and harsh parenting in predicting later reactive aggression compared to proactive aggression. The first was an additive model where both aspects make unique contributions in predicting later reactive aggression. The second model was an interactive model where harsh parenting exacerbates the link between negative emotionality and reactive aggression. Results showed a specific contribution of negative emotionality to reactive aggression. The results relative to harsh parenting are more mixed but nonetheless in line with developmental models stressing different pathways to reactive and proactive aggression.     

The associations between parenting styles and proactive and reactive aggression in Hong Kong children and adolescents

Previous research suggests that reactive and proactive aggression may be differentially related to family contextual (e.g. parenting practices) factors. However, the existing research has focused largely on children and adolescents from Western countries, and no study has examined the parenting–aggression association using a parenting style measure sensitive to Asian culture. In this study parenting styles (i.e. warmth, control and guan/training) and proactive and reactive aggression were assessed in a large sample of school children in Hong Kong, China (N = 4,175, mean age = 11.75). We found that: (a) both low warmth (in boys only) and guan (i.e. high expectation and close supervision, in both boys and girls) were associated with elevated parent‐reported proactive aggression, (b) high restrictive control (i.e. dominating and rejecting) was associated with high reactive aggression (in both boys and girls) based on parent‐ or child‐report data, and with high proactive aggression (in boys only) based on parent‐report data, and (c) guan was also positively associated with parent‐reported reactive aggression. Findings provide more information about the Parenting Inventory using a large Asian sample, and extend existing research on familial correlates of different types of aggression.     

Evidence for the Continuity of Early Problem Behaviors: Application of a Developmental Model

Evidence of the continuity of early problem behaviors in young girls and boys was examined developmentally. Data were gathered on 104 mother-child dyads from low-income families when children were between 1 and 5 years of age. Difficult temperament, aggression, and noncompliance from 12 to 24 months, and externalizing and internalizing problems at 36 and 60 months, were assessed. The results provide evidence for the continuity of early behavioral and emotional problems and support for the early differentiation between internalizing and externalizing problems. Implications of the current findings for prevention efforts are presented.     

Mediational role of parenting styles in emotional intelligence of parents and aggression among adolescents

The present study was designed to examine the relationship between parents' emotional intelligence and adolescents' aggression, through the mediation of parenting styles. Two hundred and twenty five undergraduate students (113 boys & 112 girls; age 17–18 years), from four universities in Pakistan, participated with their parents. The Parenting Styles and Dimensions Questionnaire (Robinson, Mandleco, Olsen, & Hart, 1995), and the Scale of Emotional Intelligence (Batool & Khalid, 2011) were completed by parents. The Aggression Questionnaire (Buss & Perry, 1992) was completed by their adolescent offspring. Mediational path analysis supported our hypothesised model. Results indicate that emotional intelligence of parents indirectly links to aggression among offspring, through parenting styles. It was concluded that emotional intelligence training will help parents to improve their parenting styles, and it will lower the risk of aggression in their children.     

Simultaneously Testing Parenting and Social Cognitions in Children At-Risk for Aggressive Behavior Problems: Sex Differences and Ethnic Similarities

In this cross-sectional study we examined a model in which parenting, child social information processing and self-perception are simultaneously tested as risk factors associated with aggression. Sex and ethnicity were tested as moderators of associations. The sample consisted of 206 4th grade children in the Netherlands. Parents reported on parenting, parent–child relationship, and reactive and proactive aggression whereas children reported on self-perception and social information processing. Results give support for both child social cognitive functioning and parenting as risk factors associated with aggressive behavior: For all children, a positive parent–child relationship was associated with less aggression, negative parenting was related to less positive self-perception, and deficits in social-cognitive functioning were related to aggression. Multigroup analyses showed ethnic similarities and sex differences in patterns of associations, which might suggest personalized tailor-made interventions for aggressive behavior.     

Parent Cognitions as Predictors of Child Treatment Response in Attention-Deficit/Hyperactivity Disorder

Using a subsample of 105 children and their parents (100 mothers, 57 fathers) from the Multimodal Treatment Study of Children with ADHD (the MTA), the value of parents' baseline cognitions as predictors of children's treatment outcome at 14 months was examined. Measures of parents' cognitions about themselves, their ADHD children, and their parenting, as well as a self-report measure of dysfunctional discipline were included. Both mothers' and fathers' self-reported use of dysfunctional discipline predicted worse child treatment outcome. Low self-esteem in mothers, low parenting efficacy in fathers, and fathers' attributions of noncompliance to their ADHD child's insufficient effort and bad mood also were associated with worse child treatment outcome. All of these predictive relations were obtained even after MTA treatment effects had been taken into account. Secondary analyses indicated that mothers had a more external locus of control, lower self-esteem, lower parenting efficacy, and a greater tendency to attribute noncompliance to their ADHD child's bad mood than did fathers.     

The Application of Behavioral Family Therapy to Chinese Aggressive Children

Behavioral Family Therapy (BFT) generally targets four typical disruptive behaviors among children ages from 2 to 7 years: noncompliance, aggression, tantrums, and negative talk. This study tests the effect of BFT on 20 Chinese aggressive children (16 boys and 4 girls) who were assigned to a BFT group or a control group. The results showed that the children's level of aggression in the BFT group reduced significantly compared to that of the control group, and the gains were maintained at a 6-month follow-up. These findings support the use of BFT as a treatment modality for Chinese aggressive children.     

Effectiveness of the home‐start parenting support program: Behavioral outcomes for parents and children

This study examined effectiveness of Home‐Start, a program designed to support parents with young children. The aims were (a) to examine whether Home‐Start improved maternal well‐being and (b) to examine whether Home‐Start led to changes in the behavior of mothers or children. Self‐reported and observational data were collected in two waves, using data from 54 mothers and their children between 1.5 and 3.5 years of age who participated in this intervention program for 6 months. These data were compared to 51 comparison families who reported need for parenting support. The results showed a significant improvement in perceived parenting competence, but no effects on maternal depressive moods. Mixed results were found for parenting behavior: Parental consistency and observed sensitivity improved significantly in the Home‐Start group whereas no effects were found on the other parenting variables. Child behavioral problems seemed to diminish at the second measurement in both groups, and therefore these changes cannot be attributed to Home‐Start.     

Father-infant interaction, paternal ideas about early child care, and their consequences for the development of children's self-recognition

In this longitudinal study, the authors addressed intracultural variation on fathers' interactions with their 3-month-old infants, their ideas about parental care, and the timing of their children's self-recognition at the age of 18-20 months. Participants were 24 middle-class German fathers and their firstborn children. Two behavioral clusters emerged: a more proximal parenting style with extensive body contact and a more distal parenting style with extensive object stimulation. Fathers in the distal cluster had significantly more education than did fathers in the proximal cluster. Children who had experienced more distal parenting were more likely to recognize themselves in a mirror than were children with more proximal parenting. The authors discuss the results with respect to fathers' influence on child development and patterns of intracultural variation.     

In vitro fertilization and the family: quality of parenting, family functioning, and child psychosocial adjustment

This study examined associations between homologous in vitro fertilization (IVF) and quality of parenting, family functioning, and emotional and behavioral adjustment of 3-7-year-old children. A cross-sectional survey was conducted in Taiwan with 54 IVF mother-child pairs and 59 mother-child pairs with children conceived naturally. IVF mothers reported a greater level of protectiveness toward their children than control mothers. Teachers, blind to condition, rated IVF mothers as displaying greater warmth but not overprotective or intrusive parenting behaviors toward their children. Teachers scored children of IVF as having fewer behavioral problems than control children. In contrast, IVF mothers reported less satisfaction with aspects of family functioning. Family composition moderated parenting stress: IVF mothers with only 1 child perceived less parenting stress than did those in the control group.     

COMT基因rs6267多态性与母亲教养行为对青少年身体攻击和关系攻击的交互作用

遗传与环境如何交互作用影响儿童青少年的攻击行为是当前攻击研究中的重要前沿课题之一。近年来, 分子遗传学关于人类攻击的研究已拓展到对不同攻击亚类(身体攻击和关系攻击)的遗传基础的探讨。本研究运用问卷法与DNA分型技术, 对1258名儿童进行为时4年(四年级—七年级)的追踪调查, 考察COMT基因rs6267多态性与母亲教养行为对青少年身体攻击和关系攻击的交互作用以及性别在其中的调节作用。结果发现, COMT基因rs6267多态性与母亲教养行为仅交互作用于男青少年的身体攻击, 母亲教养行为显著预测GG 基因型男青少年的身体攻击, 但对T等位基因男青少年身体攻击的预测作用并不显著。COMT基因rs6267多态性与母亲教养行为对青少年关系攻击的交互作用不显著。本研究结果表明, 身体攻击和关系攻击具有不同遗传基础和发生机制。     

Symptoms of Attention-Deficit/Hyperactivity Disorder and Social and School Adjustment: The Moderating Roles of Age and Parenting

This study examined the associations between symptoms of attention-deficit/hyperactivity disorder (ADHD) and social and school adjustment (academic performance, peer relationships, school social problems) and the moderating roles of children’s age and maternal parenting (affection and overprotection) in these associations. The sample consisted of 2,463 students who were in the first to ninth grade in northern Taiwan. Results from the linear mixed models demonstrated that ADHD symptoms were inversely associated with academic performance and positively associated with social adjustment problems. Further, children’s age and maternal parenting moderated the associations between ADHD symptoms and school and social adjustment. For example, maternal overprotection moderated the relation between hyperactivity and negative peer relationships (i.e., difficulty forming and maintaining friendships), such that this relation was stronger for children who experienced higher levels of overprotection than children who did not. Moreover, children’s age moderated the association between attention problems and decreased academic performance, such that this association was stronger for older children and adolescents than for younger children. Furthermore, children’s age and maternal affection interacted to influence the association between attention problems and school social problems (i.e., bullying, aggression, and peer rejection) with maternal affection acting as a buffer for older children (grades 4–6) only. These findings are discussed from a developmental psychopathology perspective.     

Callous-unemotional features, behavioral inhibition, and parenting: independent predictors of aggression in a high-risk preschool sample

A behaviorally-uninhibited temperament, callous-unemotional (CU) features, and harsh parenting have been associated with specific patterns of aggressive behavior in older children and adolescents. We tested the additive and interactive effects of these factors in predicting different types of aggressive behavior in a high-risk preschool sample. Forty-nine preschoolers and their parents registering for Head Start programs were recruited for participation. Behavioral inhibition, CU features, and attitudes toward various types of parenting were assessed through parent rating scales completed at the time of registration. Behavioral inhibition, CU features, and aggression were assessed by teacher ratings approximately six months later. Analyses revealed that behavioral inhibition, CU features, and harsh parental attitudes all contributed independently to the prediction of aggressive behavior. These associations were strongest for proactive types of aggression. Our results suggest that a behaviorally uninhibited temperament, CU features, and attitudes favoring harsh parenting are all important for understanding the development of aggression in preschool children.

Influence of the teacher-student relationship on childhood conduct problems: a prospective study.

Examined the influence of the quality of the teacher-student relationship on children's subsequent levels of aggression in a sample of 61 second and third-grade children nominated and rated by their teachers as aggressive. The stability of teachers' and children's reports of relationships quality across academic years was in the low to moderate range. Teachers and children showed little agreement in their reports of relationship quality. Teachers' and children's reports of relationship quality in year 1 (Y1) predicted teacher-rated aggression the following year, controlling for Y1 ratings of aggression. Teachers' reports of relationship quality across Y1 and Y2 predicted peer-rated aggression, but not teacher-rated aggression, in Y3, controlling for Y1 aggression. Consistent with a buffering role for teacher-student relationships, a positive teacher-student relationship was of greatest benefit to children whose mothers reported rejecting parenting histories. We discuss implications for school-based prevention programs.
