We assessed the psychometric properties of the Social Behavior Questionnaire (SBQ), a 30-item questionnaire evaluating social (e.g., disruptive behaviors, bullying) and emotional problems (e.g., anxiety, depression) among children aged 3.5-12 years. Children (n = 1,950, 50.21% boys) were drawn from the Quebec Longitudinal Study of Child…

The current study examined the heterogeneity in the development of school-based prosocial behavior from Grades 1 to 12 and the role of multiple early childhood antecedents in predicting heterogeneous developmental trajectories of prosocial behavior in a sample of 784 children facing early risks and vulnerabilities (predominantly from low-income…

Although it is hypothesized that children with different insecure attachment patterns may experience a variety of peer difficulties, the question has been investigated almost exclusively for externalizing and internalizing behaviors with peers. The purpose of this study was to investigate how each of the insecure attachment patterns is related to…

Sharing is an important indicator of internalised prosocial values. We examined predictors of sharing of 302 preschoolers with their younger siblings in a one-year longitudinal study. Sharing was observed during different home visits, once with father and once with mother. We examined the following predictors: both children's externalising…

The present study aimed to investigate cultural construction of children's perceptions of popularity determinants using a cross-cultural approach. This study examined 327 Chinese and 312 American fifth-graders' perceptions of what individual characteristics and peer relationships would make a peer popular. Consistent with cultural emphases,…

The purpose of this study was to evaluate the effects of a pilot school-based intervention called CEPIDEA, designed to promote prosocial behavior in early adolescence. The study took place in a middle school located in a small city near Rome. The intervention group included 151 students (52.3% males; M[subscript age] = 12.4), and the control group…

By integrating the life history theory of attachment with resource control theory, the current study examines the hypothesis that insecure attachment styles reorganized in middle childhood are alternative adaptive strategies used to prepare for upcoming competition with the peer group. A sample of 654 children in the second through seventh grades…

Using social network analysis, we investigated the characteristics of social networks composed of positive relationships (positive network: PN) and negative relationships (negative network: NN) in classrooms of Japanese 3- and 4-year-olds. Analysis of "density" showed that PNs were denser than NNs among 4-year-olds but that this was not…

In this study we investigated whether mothers' typical expressive style and specific emotional responses to children's behaviors are linked to children's prosocial and competence self-ratings. Eight- to 12-year-old children and their mothers rated how mothers had felt when children behaved prosocially and antisocially, achieved and failed to…

This study investigated the relation of peer interactions, family social environment and personality to prosocial orientation in Chinese adolescents. The results indicated no sex differences in general prosocial orientation and inclination to help others, but sex differences in inclination to maintain an affective relationship and inclination to…

Preschoolers' prosocial and aggressive behaviours were explored longitudinally, with a focus on the inferred underlying motives of these behaviours. Forty-four children (initially 22-40 months of age) were observed in naturalistic interactions with peers, during a 2-month period, for each of three consecutive years. Three categories of prosocial…

In the current study, 466 children completed a peer nomination survey assessing both perceived and sociometric popularity at the end of the 5th grade. Measures of behavior problems were assessed through a composite of peer-, teacher- and self-reports at the end of the 8th grade. Examination of the unique concurrent associations of each popularity…

This study examined children's peer relations in relation to gender, symptoms of attention-deficit/hyperactivity disorder (ADHD), associated behaviour problems, prosociality, and self-perceptions, in a community sample. Six hundred and thirty-five 12-year-old children (314 girls) provided peer nominations and rated feelings of loneliness and…
