This study examined the role of attitudes against bullying and perceived peer pressure for intervention in explaining defending the victim and passive bystanding behavior in bullying. Participants were 1031 school-age children from two culturally diverse settings, namely Italy and Singapore, which are similar on several dimensions (e.g., quality…

In the current study, we examined latent growth in 731 young children's inhibitory control from the ages of two to four years, and whether demographic characteristics or parenting behaviors were related to initial levels and growth in inhibitory control. As part of an ongoing longitudinal evaluation of the family check-up, children's inhibitory…

This study investigated the role of mutual dislike dyads (MDDs) in the development of aggressive behavior across the middle childhood years. Of particular interest was whether involvement in MDDs predicted later aggression, and whether the magnitude of the association between MDDs and later aggression varied based on characteristics of target…

This study examined the heterotypic continuity of aggression hypothesis (physical to indirect) using independent teacher reports of aggression drawn from a nationally representative sample of 749 Canadian girls and boys. Confirmatory factor analysis using an accelerated longitudinal design confirmed a two-factor model of physical and indirect…

Psychosocial precursors and correlates of parent-reported internalizing behavior trajectories across the age span of 3-15 years were explored using a community-based cohort of Australian children. Six internalizing trajectories had previously been identified for both girls (N = 810) and boys (N = 874) in this sample, comprising stable low, high,…

This study investigated the associations among psychologically controlling parenting, relational aggression, friendship quality, and loneliness during adolescence. A model was proposed in which relational aggression plays an intervening role in the relations between both parental psychological control and friendship outcomes. In a sample comprised…

Prior research has shown that parental social cognitions are associated with child outcomes such as aggression. The goal of this study was to examine mothers' cognitions about relational aggression, and to explore linkages between mothers' attributions and normative beliefs about aggression and children's competence with peers. Participants…

In Roberts and Strayer (1996), we reported that emotional expressiveness and anger were important predictors of empathy for school-age children, and that empathy strongly predicted prosocial behaviors aggregated across methods and sources. In this paper, we report how empathy was associated with direct observations of anger and aggression in peer…

We observed 48 children from rural preschools (M = 64 months old) in two different social contexts to test hypotheses about the type (relational, physical, verbal, nonverbal), contextual independence, and sociometry of girls' and boys' aggressive tactics. We predicted and generally found that (1) girls displayed more relational aggression than…

In this study we described development of boys' and girls' games on the school playground at recess as they progressed across the first year of primary school in London (UK) and Minneapolis (USA) in order to document age-related trends in games during this period and to examine the predictive role of games in children's adjustment to school and…
