This longitudinal ecological momentary assessment study examined whether adolescents' use of social media to interact with peers relates to their experiences of social connectedness, social craving, and sensation seeking on an hourly level. Further, we investigated whether these associations differ for adolescents who were nominated by their peers…

Throughout adolescence, both sleep and emotion regulation abilities undergo significant developmental changes. The maturational systems that govern sleep and emotion regulation are closely intertwined leading many researchers to posit a mutually reinforcing relationship. Although there is support for a bidirectional relationship among adults,…

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…

This study examines developmental change across adolescence in the similarity of friends versus nonfriends. This differential in similarity is a key aspect of the organization of the peer context of development: The stronger the correlation between friends for an attribute, the more the attribute delineates clustering and divisions of friendships.…

Indirect aggression has been associated with antisocial personality traits like Machiavellianism, but there is a lack of evidence on their longitudinal development across adolescence. Therefore, the joint developmental trajectories of adolescent indirect aggression and Machiavellianism across 3 years of high school (Grades 10 to 12) were…

Many studies have found that males, on average, perform better than females in mathematics, although the size of this gender gap is small and varies considerably across countries. Stereotype threat has been proposed as a principal cause of this gender gap. From this perspective, females' performance is affected by fear of confirming a negative…

This longitudinal person-centered study aimed to identify profiles of subjective task values and ability self-concepts of adolescents in the domain of mathematics, English, biology, and physics in Grades 10 and 12. We were interested in gendered changes of profile membership, and in relations between profile membership and educational and…

Persistence in high school curricula leading to science, technology, engineering, and mathematics (STEM) careers is structured by complex institutional systems, but developmental processes underlie how young people navigate these systems. This study examined differences in the development of STEM identity and efficacy during high school among…

Tenets of the Boivin et al. (1995) social process model were reexamined with two longitudinal samples using both the original and contemporary analytic strategies. Study goals included reconstructing (e.g., quasireplicating) Boivin et al.'s (1995) original findings and evaluating hypothesized relations across both comparable and longer…

Parent-adolescent relationships are related to adolescents' disclosure and concealment, but these associations may represent between-family differences (e.g., families with more negative interactions have adolescents who disclose less) or within-family processes (e.g., when a family has more negative interactions, their adolescent discloses less).…

Ethnic identity is a consistent predictor of positive youth adjustment, whereas discrimination has been associated with negative outcomes among Latino/a youth. Scholars have proposed associations between ethnic identity and discrimination; however, directionality of effects remains unclear. Addressing this gap, the current study examined the…

Although many facets of social status (i.e., socioeconomic status, gender, race) are fairly stable, limited work has assessed how youths' identification with their status changes over time. Subjective social status (SSS) refers to one's perception of standing or rank relative to others, and for youth status is generally in the context of society…

The present study used a genetically informed design of twins raised in the same family (375 monozygotic and 290 dizygotic twins; 50.2% girls) to examine the association between adolescents' genetic risk for depressive symptoms and the course of the parent-child relationship quality throughout adolescence. Depressive symptoms and the quality of…

Hispanic adolescents have high expectations for their own educational attainment, but educational attainment outcomes for Hispanic young adults are relatively low on average. Limited scholarship links Hispanic adolescents' educational expectations with attainment in adulthood. Using a longitudinal within-group approach, the authors examined…

The current study examined the trajectory of gender role attitudes of 471 Mexican-origin adolescents (236 girls, 235 boys) from 5th grade (M[subscript age] = 10.86 years) to 11th grade (M[subscript age] = 16.75 years), investigating how situating identities (i.e., gender, nativity, SES), ethnic identity (i.e., ethnic pride), and familial context…
