Children's Rumination to Sadness and Anger: Implications for the Development of Depression and Aggression.

The current study examined the transdiagnostic nature of rumination in the development of childhood depression and aggression by examining the relation between two forms of rumination, sadness and anger, in a single study and assessing their unique and shared behavioral correlates. A community sample of 254 children (ages 7-14, 50.4% female, 66.5% Caucasian) completed self-report measures of rumination and depressive symptoms, and peer nominations of aggressive behaviors. Hierarchical regression analyses were conducted to assess unique and shared behavioral correlates. Anger rumination uniquely predicted aggression (ß = .40, p < .001) and depressive symptoms (ß = .62, p < .001), controlling for sadness rumination. Sadness rumination, controlling for anger rumination, did not predict depressive symptoms (ß = -.10, p = .10) and negatively predicted aggressive symptoms (ß = -.21, p = .003). In addition, a significant interaction between sadness rumination and anger rumination on aggressive behaviors was observed (ß = -.24, p < .001), such that children who reported high anger and low sadness rumination tendencies were perceived as more aggressive by their peers than other children, including those with high levels of anger and sadness rumination. These results offer support for anger rumination as a transdiagnostic factor for children's depressive symptoms and aggression. Sadness rumination did not uniquely predict depressive symptoms, although it did moderate the association between anger rumination and aggression. These findings underscore the importance of assessing both anger and sadness rumination for increasing our understanding of children's risk for depression and aggression.

Positively biased self-perceptions of peer acceptance and subtypes of aggression in children.

There is a growing body of research linking children's positively biased self-perceptions with higher levels of aggression. This study extended this area of research by examining prospective associations of positively biased self-perceptions of peer acceptance with overt and relational aggression. In addition, moderating effects of peer rejection were examined to test the "disputed overestimation hypothesis," which posits that the link between bias and aggression is limited to children who are rejected by their peers. Using a two-wave longitudinal design, measures of peer-rated and self-perceived peer acceptance and peer-rated overt and relational aggression were obtained for 712 children in 3rd through 5th grades (386 girls and 326 boys). Positively biased perceptions led to increases in relational, but not overt, aggression. This pattern was observed even when the effects of gender, race, peer rejection, and overt aggression on relational aggression were controlled. Contrary to the disputed overestimation hypothesis, the prospective associations between bias and aggression did not vary as a function of children's peer rejection status, thus supporting the view that positive bias predicts future aggressive behavior, regardless of social status. The results are discussed in terms of the comparability with previous findings and practical implications.

Positively Biased Self-Perceptions: Who Has Them and What are Their Effects?

This study examined demographic and social competency characteristics of children who hold overly-positive self-perceptions of their social acceptance (positive bias). The effects of holding positive bias on aggressive and depressive symptoms were examined in a sample that excluded children on the extreme negative end of the bias continuum. Measures of peer-rated and self-perceived acceptance were obtained for 366 children in the 3rd through 5th grades. Peer-rated aggressive behavior and self-reported depressive symptoms were also collected. Results demonstrated sex, ethnicity, and social preference were uniquely associated with positive bias. Positive bias was related to aggression beyond the effects of social preference. Positive bias was not related to depressive symptoms. This study clarified who is likely to hold positive bias and replicated findings that suggest positive bias is a risk factor for aggressive outcomes. The idea that positive bias is neither a risk nor protective factor for depressive symptoms is discussed.

Self-perceptions and their Prediction of Aggression in Male Juvenile Offenders.

This study evaluated multiple facets of self-perceptions that have been theorized and shown to play a contributory role in the development of aggression for less clinically severe populations in a sample of youths from the juvenile justice system. Independent and unique associations of low self-esteem and inflated self-perceptions with aggression were examined in a sample of male juvenile offenders (N = 119; Mean age = 16.74 years) using a longitudinal study design. Latent growth curve modeling analyses revealed that self-esteem, adaptive and maladaptive narcissism independently predicted juvenile offenders' initial levels of aggression. It was also found that perceptual bias independently predicted changes in aggression over time. With the inclusion of all variables in the same model, self-esteem was no longer associated with aggression; however, all other relationships remained significant. The implications of these findings as well as the importance of interventions targeting self-perceptions to decrease aggression among high-risk youths are discussed.

Parental influence on children with attention-deficit/hyperactivity disorder: I. Relationships between parent behaviors and child peer status.

We examined associations between children's peer relationships and (a) their parents' social competence as well as (b) their parents' behaviors during the children's peer interactions. Participants were families of 124 children ages 6-10 (68% male), 62 with ADHD and 62 age- and sex-matched comparison youth. Children's peer relationships were assessed via parent and teacher report, and sociometric nominations in a lab-based playgroup. Parental characteristics were assessed via parent self-report and observations of behavior during their child's playgroup. After statistical control of relevant covariates, parents of children with ADHD reported poorer social skills of their own, arranged fewer playdates for their children, and displayed more criticism during their child's peer interaction than did parents of comparison youth. Parents' socialization with other parents and facilitation of the child's peer interactions predicted their children having good peer relationships as reported by teachers and peers, whereas parental corrective feedback to the child and praise predicted poor peer relationships. Parents' ratings of their child's social skills were positively associated with ratings of their own social skills, but negatively associated with criticism and facilitation of the child's peer interactions. Relationships between parental behaviors and peer relationships were stronger for youth with ADHD than for comparison youth. The relevance of findings to interventions is discussed.
