To explore subtypes of social withdrawal in different sociocultural contexts, concurrent social, school, and academic correlates of shyness and unsociability were examined in 93 urban (Mage = 14.05, SD = 0.86 years) and 136 rural (Mage = 14.39, SD = 0.69 years) seventh and eighth graders from Liaoning, China. Adolescents' shyness and unsociability were assessed with self-, peers’, and teachers’ reports. Peer-group relationships (acceptance, rejection, and exclusion) were obtained from peer nominations. Adolescents reported perceived friendship quality (positive friendship quality, conflict and betrayal) and school attitudes (school liking and avoidance). Teachers rated students' academic engagement and performance. Academic achievement (exam grades) also was obtained from school records.

According to factor and correlational analyses, shyness and unsociability emerged as distinct, but positively related, constructs, within each informant. Cross-informant agreements on shyness and unsociability were low to moderate, especially between teachers' and self- or peers' reports. Urban-rural differences were expected in the associations of shyness, but not of unsociability, with the correlates, but the hypotheses were not supported with multiple-group (urban vs. rural) path models. In the combined (urban and rural) sample, shyness was associated with negative peer relationships, low friendship quality, and negative school attitudes (for self- but not peer-reported shyness), but was unrelated to academic correlates. Self-reported unsociability related negatively to positive friendship quality and positively to academic achievement, but was unrelated to other adjustment correlates. Peer-reported unsociability, however, was associated with negative peer relationships, less positive friendship quality, low school liking, low academic performance, and low academic achievement.

The study was an initial step towards understanding subtypes of social withdrawal and adjustment correlates in various domains among Chinese adolescents living in different social contexts. The lack of urban-rural differences was not consistent with the contextual-development theory. Like their Western peers, shy Chinese adolescents were at risk for relational and school adjustment problems, but they did not have academic difficulties. Unsociable Chinese adolescents also tended to have poor adjustment at school, including relational problems with peers and friends, negative school attitudes, and academic difficulties, but only when they were perceived as unsociable by peers, rather than themselves.

It is widely recognized that peer-directed aggression and victimization are pervasive social problems that impact school-aged children and adolescents. This study investigated the developmental course of aggression and victimization, and more specifically, addressed three primary aims. First, distinct subgroups of children were identified based on similarities and differences in their physical, verbal and relational aggression and victimization. Second, developmental stability (and instability) were assessed by examining the extent to which individuals remain (or change) subgroups throughout childhood and adolescence. Third, group classifications and transitions over time were assessed as a function of children’s individual characteristics and their relational and contextual experiences.

The sample for this longitudinal study consisted of 482 children (50% females) who were followed over time from grades 1 to 11. Multiple-informant data on children’s physical, verbal and relational aggression and victimization (peer-reports), individual characteristics including emotion dysregulation, withdrawn behaviors (teacher-reports), and hostile and self-blaming attributions (self-reports), and their relational and contextual experiences including peer rejection, friendships, social hierarchy and classroom aggression (peer-reports) were assessed in grades 1, 5, 8, and 11. Data analyses primarily consisted of a series of person-centered methods including latent profile and latent transition analyses.

Most of the identified subgroups (e.g., aggressors, victims and aggressive-victims) were distinguishable by their frequencies (i.e., levels) of aggression and victimization, rather than forms (physical, verbal and relational), with the exception of one group that appeared to be more form-specific (i.e., relational aggressive-victims). Among children in each group there was a modest degree of intra-individual stability, and findings elucidated how some groups appeared to be more stable than others as well as developmental differences. Although group stability was fairly common across all groups, and over time, patterns of instability also emerged.

The combination of trends reflecting both stability and instability support the perspective that the development of aggression in childhood and adolescence is characterized by heterogeneity. In contrast to perspectives that highlight the individual stability of aggression (e.g., that it is a stable behavioral style or individual disposition), findings elucidate the individual, relational and contextual mechanisms by which developmental stability and instability were more pronounced.

The current study expands prior work on children's coping with peer victimization by employing person-centered analyses to identify discrete classes of coping behavior, associations with children's maladjustment, and patterns of stability and change over time. Specifically, data were collected at two longitudinal time points from 515 middle school children who reported experiencing at least occasional peer victimization (284 girls, 231 boys; Mage = 8 years, 5 months, SDage = 10.38 months). Three active, behavioral coping strategies were examined: support seeking from teachers, support seeking from friends, and retaliation. A series of cross-sectional latent profile analyses suggested that coping styles may be characterized by 3 distinct classes: (1) support seeking, (2) retaliation, or (3) a combination of these strategies, labeled mixed strategy coping. Peer victimization, depression, and loneliness were included as concurrent covariates of class membership and results indicate that mixed strategy coping may put children at greater social and emotional risk, whereas both support seeking and retaliation may pose potential benefits in the face of victimization. Further, longitudinal latent transition analyses were conducted to examine the stability and change in coping over time, indicating that coping is largely dispositional, though has the potential to change, particularly among children who experience shifts towards greater maladjustment over time. Results emphasize mixed strategy coping - a coping style that is underrepresented in the current research - as both an important factor that may contribute to greater social and emotional difficulties and also as a potential transitioning point during which change in children's coping may be addressed.

This study examined the influence of childhood aggression, peer exclusion and associating with deviant peers on the development of antisocial behavior in early adolescence. To gain a stronger understanding of how these factors are associated with antisocial behavior and delinquency, multiple alternative pathways were examined based on additive, mediation and incidental models. A parallel process growth model was specified to assess whether early childhood aggression and peer exclusion (in 1st grade) and intra-individual increases in aggressive behaviors and exclusion through childhood (grades 1 to 6) are predictive of associating with deviant peers (in 7th grade) and antisocial behavior (in 8th grade). Based on a sample of 383 children (193 girls and 190 boys), results showed the strongest support for an additive effects model in which early childhood aggression, increases in aggression, increases in peer exclusion and associating with more deviant peers all predicted antisocial behavior. These findings have implications for how children's psychological adjustment is impacted by their behavioral propensities and peer relational context and the importance of examining developmental processes within and between children over time.
