Regrouping: organized activity involvement and social adjustment across the transition to high school.

Although organized activities (OAs) have been established as important contexts of development, limited work has examined the role of OAs across the high school transition in buffering adolescents' social adjustment by providing opportunities for visibility and peer affiliation. The transition to high school is characterized by numerous changes and OAs may provide an important setting for establishing and maintaining peer relationships during this tumultuous time. This study included 151 8th grade U.S. students (58% male) who were assessed across the transition to high school (spring of 8th and 9th grade). Continuous involvement in academic activities across the transition and becoming involved (i.e., initiation) in community/service activities following the transition was associated with fewer depressive symptoms in the spring of 9th grade. Continuous involvement in sports and initiation of academic activities was associated with having more friendships. In addition, links between OAs and loneliness were only evident among females. There appear to be significant social benefits for OA involvement.

Attachment stability and the emergence of unresolved representations during adolescence.

This 15-year longitudinal study examined the stability of attachment representations from infancy to adolescence and investigated the emergence of unresolved representations during adolescence in a sample of 47 16-year-olds. Attachment was assessed at 12 months using the Strange Situation Procedure, at 4 years using the modified Strange Situation Procedure, and again at 16 years with the Adult Attachment Projective (AAP). The emergence of unresolved classifications in adolescence (AAP) was associated with higher rates of negative life events, low levels of early mother-child relationship security (an aggregate measure of the 12-month and 4-year measures), negative teacher-child relationship experiences in middle childhood, and low early adolescent friendship quality. The results support the growing body of evidence suggesting that changes in attachment are lawful, while adding to the growing understanding of the emergence of unresolved attachment representations.

Longitudinal trajectories and predictors of adolescent suicidal ideation and attempts following inpatient hospitalization.

Remarkably little is known regarding the temporal course of adolescent suicidal ideation and behavior, the prediction of suicidal attempts from changes in suicidal ideation, or the prediction of suicidal attempts after accounting for suicidal ideation as a predictor. A sample of 143 adolescents 12-15 years old was assessed during psychiatric inpatient hospitalization and again at 3, 6, 9, 15, and 18 months postdischarge through a series of structured interviews and parent- and adolescent-reported instruments. Symptoms of depression, posttraumatic stress disorder, externalizing psychopathology, hopelessness, and engagement in several forms of self-injurious/suicidal behaviors (i.e., suicide threats/gestures, plans, nonsuicidal self-injury [NSSI]) were assessed. Latent growth curve analyses revealed a period of suicidal ideation remission between baseline and 6 months following discharge, as well as a subtle period of suicidal ideation reemergence between 9 and 18 months postdischarge. Changes in suicidal ideation predicted suicide attempts. After accounting for the effects of suicidal ideation, baseline suicide threats/gestures also predicted future suicide attempts. Higher adolescent-reported depressive symptoms, lower parent-reported externalizing symptoms, and higher frequencies of NSSI predicted weaker suicidal ideation remission slopes. Findings underscore the need for more longitudinal research on the course of adolescent suicidality.

Romantic partner selection and socialization during early adolescence.

This prospective study examined romantic partner selection and socialization among a sample of 78 young adolescents (6th-8th graders). Independent assessments of adolescent and romantic partner adjustment were collected before and after relationships initiated via peer nomination and self-report. Prior to their relationship, adolescents and partners were significantly alike on popularity, physical attraction, and depressive symptoms. Controlling for initial similarity, partners' popularity, depressive symptoms, relational aggression, and relational victimization significantly predicted changes in adolescents' functioning in these areas over time. However, the magnitude and direction of change varied according to adolescents' and partners' prerelationship functioning. In general, adolescents who dated high-functioning partners changed more than those who dated low-functioning partners, and partner characteristics predicted greater change among low- versus high-functioning adolescents. Results were consistent even when controlling for best friend characteristics. The current findings are among the first to demonstrate unique contributions of romantic partner characteristics to adolescents' psychosocial functioning.

Moderators of the association between relational aggression and perceived popularity.

This study, which involved two waves of measurement over a period of 12 months, examined first whether the positive association between relational aggression and two types of high status was moderated by social self-efficacy, leadership, cooperation, and peer sociability. It was expected that relational aggressors are most likely to gain high peer group status when they are also self-efficacious or prosocial. Second, this study examined the reciprocal association between relational aggression and high peer status. It was anticipated that relational aggression would contribute to higher perceived popularity and vice versa. Third, we also examined and hypothesized reciprocal effects between social self-efficacy, leadership, cooperation, and peer sociability and perceived popularity. Youth were 540 13-15 year olds participating in Grade 7 (Time 1) and again 1 year later in Grade 8 (Time 2). Data were collected from peers, teachers, and the adolescents themselves. Consistent with expectations, relationally aggressive adolescents high in social self-efficacy, leadership, cooperation, and peer sociability were higher in status than relationally aggressive individuals with low levels of these characteristics. In addition, relational aggression and perceived popularity reciprocally influenced each other. Finally, social self-efficacy, leadership, cooperation, and peer sociability reciprocally influenced and were influenced by perceived popularity.

Adolescent girls' interpersonal vulnerability to depressive symptoms: a longitudinal examination of reassurance-seeking and peer relationships.

A transactional, interpersonal framework involving adolescents' reassurance-seeking and peer experiences may be useful for understanding the emergence of gender differences in depression prevalence during the adolescent transition. Sociometric nominations of peer acceptance/rejection and ratings of friendship quality provided by adolescents and their friends were used to measure peer experiences among 6th-8th-grade adolescents (N=520) over 3 annual time points. After controlling for age and pubertal development, significant but small prospective effects offered mixed support for hypotheses: (a) depressive symptoms and negative peer relations predicted increasing levels of girls' reassurance-seeking; (b) initial levels of reassurance-seeking and depressive symptoms predicted deteriorating friendship quality among girls and low friendship stability, respectively; and (c) reassurance-seeking combined with poor peer experiences predicted increases in girls' depressive symptoms.

Children's peer selection: experimental examination of the role of self-perceptions.

Although previous studies have examined characteristics of children selected as friends, little research has examined the role played by characteristics of the selecting child. In 2 experimental studies that examined the role of self-perceptions in peer selection, participants (91 seventh graders in Study 1 and 83 third graders in Study 2) viewed various evaluations of themselves. Participants either believed evaluations were written by unfamiliar peers (Study 1) or were asked to imagine that the views of puppets were views of unfamiliar peers (Study 2). Participants were asked to select the peers they wished to meet and interact with. When evaluations were related to specific competence domains, 7th graders preferred positive peers to negative peers, whereas 3rd graders selected peers who viewed them as they viewed themselves. When evaluations were related to global self-worth, children's selections were unrelated to views of their own global worth. Selection of a globally negative peer was associated with attachment-insecurity/maternal-rejection and depressive symptoms.

Cognitive moderators of the longitudinal association between peer rejection and adolescent depressive symptoms.

This longitudinal study examined peer rejection as a predictor of adolescent depressive symptoms during the critical developmental period associated with substantial increases in the prevalence of girls' depression. In a sample of 158 adolescents aged 15-17 years, a peer nomination, sociometric assessment was conducted to examine adolescents' peer status at an initial time point, along with self-report measures of depressive symptoms, depressogenic attributions, and peer importance. Adolescents completed a second measure of depressive symptoms 17 months later. Results were consistent with integrated cognitive vulnerability-stress and cognitive dissonance models, particularly for girls. Specifically, peer rejection was a significant prospective predictor of depressive symptoms when combined with high levels of importance ascribed to peer status and high levels of adolescents' depressogenic attributional styles.
