Observation of early childhood physical aggression: a psychometric study of the system for coding early physical aggression

We investigated the reliability and (convergent and discriminant) validity of an observational measure of physical aggression in toddlers and preschoolers, originally developed by Keenan and Shaw [1994]. The observation instrument is based on a developmental definition of aggression. Physical aggression was observed twice in a laboratory setting, the first time when children were 1-3 years old, and again 1 year later. Observed physical aggression was significantly related to concurrent mother-rated physical aggression for 2- to 4-year-olds, but not to maternal ratings of nonaggressive externalizing problems, indicating the measure's discriminant validity. However, we did not find significant 1-year stability of observed physical aggression in any of the age groups, whereas mother-rated physical aggression was significantly stable for all ages. The observational measure shows promise, but may have assessed state rather than trait aggression in our study.     

A longitudinal study of relational aggression, physical aggression, and children's social-psychological adjustment

Although great strides have recently been made in our understanding of relational aggression and its consequences, one significant limitation has been the lack of prospective studies. The present research addressed this issue by identifying and assessing groups of relationally aggressive, physically aggressive, relationally plus physically aggressive (co-morbid), and nonaggressive children during their third grade year in elementary school and then reassessing them a year later, during fourth-grade (N = 224, 113 girls). Two aspects of social-psychological adjustment were assessed during both assessment periods including internalizing difficulties (i.e., withdrawal, depression/anxiety, and somatic complaints) and externalizing problems (i.e., aggressive behavior, delinquency). It was revealed that the strongest predictor of future social-psychological adjustment problems and increases in these problems from third to fourth was the combination of relational and physical aggression. Relational aggression also contributed unique information, relative to physical aggression, in the prediction of future maladjustment. Implications of these findings for future research and prevention efforts, particularly for aggressive girls, are discussed.     

Young children's natural learning environments: contrasting approaches to early childhood intervention indicate differential learning opportunities

1,000 parents of infants and toddlers enrolled in early childhood intervention programs were surveyed about the number of learning opportunities provided their preschool children using different approaches to early intervention. Findings showed that more learning opportunities were reported when participation in everyday activity settings was conceptualized as a type of intervention rather than as settings for professionals to conduct their interventions.     

Prevention of antisocial behaviour: Evaluation of an early intervention programme

The prognosis of children showing antisocial behaviour is not favourable. Longitudinal research shows a high level of stability of antisocial behaviour. The present study aims to evaluate an early intervention project to reduce antisocial behavioural problems in at-risk children (4 – 7 years). Parent Management Training (PMT) was chosen because it was evaluated as a promising intervention in previous research. The training is based on social learning principles and teaches parents to manage their child's behaviour through behaviour modification. Parents were randomly assigned to two conditions: an intervention condition (PMT; n = 34) and a waiting list condition (WL; n = 30). The PMT consists of 11 sessions spread over a 6-month period. Parents were trained in groups of 8 – 10 parents. A multi-method multi-informant methodology was designed to evaluate the programme. Measures were assessed before and after treatment and at 1-year follow-up. Both short- and long-term results revealed positive effects of the intervention with respect to the child's behaviour. In addition, parental stress reduced, whereas parental skills and mother – child interactions improved. However, no time by group interaction effects were found. Implementations and limitations of early intervention and prevention of antisocial behaviour are discussed.     

Outcome expectancies and outcome values as predictors of children's aggression

Social learning theory predicts that outcome expectancies and values should independently predict behavior, but past studies of aggression have failed to test this hypothesis specifically. We asked low–socioeconomic status children to imagine themselves engaging in aggressive behaviors and to rate the likelihood of each of a number of outcomes (outcome expectancies) and to rate how much they cared about those outcomes (outcome values). The relationship between self-reported aggression and outcome expectancies, values, and expectancy by value interactions was assessed. Expectancies, values, and their interactions were differentially related to aggression depending on the specific outcome investigated (e.g., punishment, bad feelings in self or other, prevention of future aggression, and peer respect). Results are discussed in terms of implications for theory and for future research. Aggr. Behav. 24:439–454, 1998. © 1998 Wiley-Liss, Inc.     

A parent intervention with a growth mindset approach improves children's early gesture and vocabulary development

Socioeconomic disparities in children's early vocabulary skills can be traced back to disparities in gesture use at age one and are due, in part, to the quantity and quality of communication children are exposed to by parents. Further, parents' mindsets about intelligence contribute to their interactions with their children. We implemented a parent gesture intervention with a growth mindset component with 47 parents of 10‐month‐olds to determine whether this approach would increase parents' use of the pointing gesture, infants' use of pointing, and child vocabulary growth. The intervention had an effect on parent gesture such that by child age 12‐months, parents who received the intervention increased in their pointing more than parents in the control condition. Importantly, the intervention also had a significant effect on child gesture use with parents. There was no main effect of the intervention on child vocabulary. Further, the effect of the intervention on pointing was stronger for parents who endorsed fixed mindsets at baseline, and had an added benefit of increased vocabulary growth from 10–18 months for children of those parents who endorsed fixed mindsets. Incorporating growth mindset approaches into parenting interventions is encouraged.     

A link between mothers' disciplinary strategies and children's relational aggression

This study examines the association between maternal disciplinary strategies and children's level of relational aggression, and then compares these associations with those found with overt aggression. Eighty‐two 4th graders (aged 9–11 years) completed peer nomination measures of relational and overt aggression, and their mothers completed a questionnaire designed to assess their use of disciplinary strategies (e.g. authoritarian, authoritative, permissive). Consistent with prior research, parental reliance on authoritarian strategies was positively associated with children's level of overt aggression, especially among boys. There was also a trend towards a positive association between authoritarianism and relational aggression among both boys and girls. In addition, this study is the first to show a positive association between maternal permissiveness and relational aggression. This association appears to be specific to relational, and not overt aggression, and emerge more strongly for girls than boys. The implications of these results for understanding the developmental underpinnings of relational aggression are discussed.     

Associations between parental control and children's overt and relational aggression

The present study examined specialized associations between parental control and child aggression in a sample of 600 8‐ to 10‐years old children. Parental control dimensions and aggression subtypes were assessed using multiple informants (i.e. children, mothers, fathers, peers, and teachers). In line with expectations, parental physical punishment was positively associated with overt aggression, whereas parental psychological control was positively associated with relational aggression in both girls and boys. In addition, this study demonstrated that if both parents employed similar parenting strategies, it appeared to have a cumulative effect on child aggressive behaviour. Associations involving overt aggression were more pronounced for boys than girls, whereas associations involving relational aggression were not moderated by gender. Overall, the present study contributes to an emerging research field by supporting the hypothesis of specialized associations between parental control and child aggression.     

An empirical examination of sex differences in scoring preschool children's aggression

Sex differences in adults’ observations and ratings of children’s aggression was studied in a sample of preschool children (N = 89, mean age = 44.00 months, SD = 8.48). When examining the direct observations made by trained observers, male observers, relative to female observers, more frequently recorded aggressive bouts, especially of boys. On rating scales assessing aggression, trained male raters also gave higher aggressive ratings than female raters. Lastly, we compared the ratings of trained female raters and female teachers on the same scale and found no differences. Results are discussed in terms male raters’ and observers’ prior experiences in activating their experiential schemata where males’ greater experience in aggression, relative to that of females, leads them to perceive greater levels of aggression.     

Classroom-based cognitive-behavioral intervention to prevent aggression: Efficacy and social validity

Classroom teachers need effective, efficient strategies to prevent and/or ameliorate destructive student behaviors and increase socially appropriate ones. During the past two decades, researchers have found that cognitive strategies can decrease student disruption/aggression and strengthen pro-social behavior. Following preliminary pilot work, we conducted a study to determine whether a classwide, social problem-solving curriculum affected measures of knowledge and behavior for 165 4th and 5th grade students at risk for behavior problems. We found significant positive treatment effects on knowledge of problem-solving concepts and teacher ratings of aggression. Outcomes differed across teachers/classrooms, and there was no evidence that booster lessons affected treatment efficacy. Teacher ratings of social validity were generally positive. We discuss issues about classroom-based prevention research and future research directions.     

The role of teacher behavior in children's relational aggression development: A five-wave longitudinal study

The present article examined the development of relational aggression in middle childhood and the effects of observed teacher behavior on this development. Relying on social learning theory, we expected that teacher praise would slow down the increase of relational aggression, whereas teacher reprimands would promote the increase of relational aggression. A sample of 570 children (49% boys, M_age = 7 years and 5 months, > 95% Belgian) was followed from second to fourth grade. Teacher praise and reprimands were observed at the beginning of second grade. Child relational aggression was assessed using teacher and peer reports, collected at five points in time: at the beginning and end of the second grade, at the beginning and end of the third grade, and at the end of the fourth grade. Multilevel modeling showed that relational aggression generally increased from second to fourth grade. Moreover, when teachers displayed more praise, students' relational aggression increased at a slower rate; when teachers displayed more reprimands, students' relational aggression increased at a faster rate. Overall, the results stress the importance of supporting teachers to reduce reprimands and increase praise when interacting with children.     

Social-information-processing factors in reactive and proactive aggression in children's peer groups

We examined social-information-processing mechanisms (e.g., hostile attributional biases and intention-cue detection deficits) in chronic reactive and proactive aggressive behavior in children's peer groups. In Study 1, a teacher-rating instrument was developed to assess these behaviors in elementary school children (N = 259). Reactive and proactive scales were found to be internally consistent, and factor analyses partially supported convergent and discriminant validities. In Study 2, behavioral correlates of these forms of aggression were examined through assessments by peers (N = 339). Both types of aggression related to social rejection, but only proactively aggressive boys were also viewed as leaders and as having a sense of humor. In Study 3, we hypothesized that reactive aggression (but not proactive aggression) would occur as a function of hostile attributional biases and intention-cue detection deficits. Four groups of socially rejected boys (reactive aggressive, proactive aggressive, reactive-proactive aggressive, and nonaggressive) and a group of average boys were presented with a series of hypothetical videorecorded vignettes depicting provocations by peers and were asked to interpret the intentions of the provocateur (N = 117). Only the two reactive-aggressive groups displayed biases and deficits in interpretations. In Study 4, attributional biases and deficits were found to be positively correlated with the rate of reactive aggression (but not proactive aggression) displayed in free play with peers (N = 127). These studies supported the hypothesis that attributional biases and deficits are related to reactive aggression but not to proactive aggression.     

Family expressiveness and parental emotion coaching: their role in children's emotion regulation and aggression

In this study, we explored the relations between positive and negative family expressiveness, parental emotion coaching, child emotion regulation, and child aggression. The sample included 120 fourth-grade children and their mothers. Mothers completed the Emotion Regulation Checklist, the Family Expressiveness Questionnaire, and a portion of the meta-emotion interview to assess their awareness and acceptance of, and instruction in managing their child's anger and sadness (3 dimensions of parental emotion coaching). Teachers rated each child's aggression and completed the Emotion Regulation Checklist for each child. The 3 dimensions of parental emotion coaching and positive and negative family expressiveness were not directly related to child aggression. However, both negative family expressiveness and the mother's acceptance of the child's negative emotions were indirectly related to child aggression through the child's emotion regulation.
