The present study examined how friends' responses to each other during problem talk predicted depressive symptoms over time. Participants included 271 adolescent friend dyads (69 female and 69 male early adolescent dyads; 72 female and 61 male middle adolescent dyads; 66.4% White and 26.6% Black). The adolescents were observed discussing a problem…

Self- and group orientations represent distinct ways of perceiving the relations between the world and the self and are relevant to adolescents' development. Most of the existing studies in this area are cross-sectional, providing little information about how self- and group orientations develop. This 3-year longitudinal study examined the…

This study examined longitudinal associations between early adolescents' school friendship stability, instability, and network size and their perceived social adjustment. The final sample consisted of 430 early adolescents residing in seven Midwestern schools (52% female, 47% Black, 42% White, 5% Hispanic or Latinx, and 6% Other). School…

Peer victimization is a common concern in adolescence that includes both relational (e.g., exclusion, rumor spreading) and overt (e.g., hitting, threatening) forms (Crick & Bigbee, 1998). Relational and overt peer victimization have shown to be differentially associated with depressive symptoms, with relational peer victimization showing a…

The present study tests two predictions stemming from the hypothesis that a source of difficulty with rational numbers is interference from whole number magnitude knowledge. First, inhibitory control should be an independent predictor of fraction understanding, even after controlling for working memory. Second, if the source of interference is…

Gender stereotypes about science, technology, engineering, and math (STEM) are salient for children and adolescents and contribute to achievement-related disparities and inequalities in STEM participation. However, few studies have used a longitudinal design to examine changes in gender stereotypes across a range of STEM fields. In a large,…

Friendships are important sources of support during adolescence. However, a growing literature indicates some adolescents co-ruminate, or talk with friends about problems in a way that is excessive, speculative, and negatively focused, which confers risk for internalizing problems. Still, previous research had not examined the types of problems…

Effective social support from teachers, peers, and guardians is a key to promoting students' study wellbeing at school. However, little longitudinal research has examined the implications of distinctive combinations of social support for students' study wellbeing. To address this limitation, we measured multiple dimensions of school-related social…

Nowadays, an increasing number of children and adolescents living in Europe have an immigrant background. Because ethnicity is a recognizable characteristic that may become the driver of bullying, these youths are at high risk of victimization. School interventions based on peer-led approaches, assuming all the conditions postulated in contact…

Adolescents' (n = 342, 169 boys) general algebra and algebra word problems performance were assessed in 9th grade as were intelligence, academic achievement, working memory, and spatial abilities in prior grades. The adolescents reported on their academic attitudes and anxiety and their teachers reported on their in-class attentive behavior in 7th…

This research examines whether prior research may not have detected cultural-specificity in the role of controlling and autonomy-supportive parenting in children's adjustment because of reliance on between-individual analyses. In two longitudinal studies (Ns = 825 and 934) of early adolescents, within-individual analyses were conducted to examine…

Prior research links need for approval (NFA; the extent to which self-worth is contingent on peer approval or disapproval) to critical developmental outcomes, but little is known about how NFA develops over time or within social contexts. To address this gap, the present study used a sophisticated analytic approach (autoregressive latent…

This research examined parents' restriction of children's peer relationships in the United States and China. American and Chinese children (N = 934; M[subscript age] = 12.67 years) reported on their parents' peer restriction (e.g., limiting children's time with peers) and their behavioral and psychological adjustment 3 times over a year.…

Guided by the life course perspective, this study investigated the developmental antecedents of contact, closeness/warmth, and negativity in young adults' relationships with their parents. Taking the developmental systems approach, we considered interindividual differences in not only initial levels of parenting quality in early adolescence (Grade…

To elucidate the processes underlying the cultural construction of adolescence, this research examined youth's stereotypes about teens in Hong Kong and Chongqing, a relatively less developed city in Mainland China. Youth (N = 1,269) reported on their teen stereotypes and problem behavior in the fall and spring of 7th grade. Youth in Hong Kong (vs.…
