Research suggests that the process of adolescents exploring and developing clarity about their ethnic-racial identity (ERI) is an important developmental competency. However, the extent to which individuals view their ERI as central to their overall self-concept (i.e., ERI centrality) informs the degree to which they choose to explore their ERI,…

Negative interactions with the legal system can inform adolescents' relationships with schools. The present daily-diary study examined 13,545 daily survey assessments from 387 adolescents (M[subscript age] = 13-14; 40% male; 32% Black, 50% White, and 18% Other ethnic-racial minority) across 35 days to assess whether police stops predicted…

Despite a growing understanding about civic development, we know little about whether the developmental course of civic engagement is the same across different types of civic engagement or different groups of youth. To advance developmental science in this area, we documented age-related change in community service, political interest, electoral…

It is widely believed that there is a crisis of confidence in law enforcement in the United States. What remains to be seen, however, is whether adolescents actually differentiate between legal authorities and other types of authorities. Leveraging cross-sectional, nationally representative data of 12th graders from every year from 2006 to 2017…

We examined developmental changes in self-esteem from late childhood to late adolescence in African American girls (N = 124), comparing skin tone groups. Girls completed a measure of self-esteem when they were in Grades 5, 7, 10, and 12, and in Grade 12 their skin tone was rated on a 3-point scale (1 = "Light," 2 = "Medium," 3…

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…

Little is known about the naturalistic development of mindfulness in adolescence and how it relates to changes in emotional well-being. The current longitudinal study examined the development of one dimension of mindfulness, nonreactivity to difficult inner experience (or in more colloquial terms, being able to notice, but "take a step…

Math and science motivational beliefs are essential in understanding students' science, technology, engineering, and math (STEM) achievement and choices in high school and college. Drawing on the Eccles' expectancy-value theory and Arnett's emerging adulthood framework, this study examined the relations among high school students' motivational…

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.…

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…

Developmental theory posits that youth are civically engaged in different ways, patterns of civic development vary across individuals, and both stability and change in youth civic engagement can be influenced by experiences in context. Drawing on these notions, we used a longitudinal person-oriented approach to document stability and change in…

This study investigated the effects of internal and demographic variables on civic development in late adolescence using the construct "civic purpose." We conducted surveys on civic engagement with 480 high school seniors, and surveyed them again 2 years later. Using multivariate regression and linear mixed models, we tested the main…

We examined the effects of family functioning trajectories on sexual risk behaviors and STI in adolescents. A sample of 850 predominantly (80%) Black adolescents from Michigan, United States, was assessed at baseline, 12, 24, and 36 months postbaseline. Adolescents were from working-class families with a mean age of 14.9 years (SD = 0.64, Range =…

Based on a longitudinal sample of 1,452 African American and European American adolescents and their parents, parenting practices (i.e., monitoring, warmth, and autonomy support) at 7th grade had significant indirect effects on college enrollment 3 years post high school, through their effects on aspirations, school engagement, and grade point…

The movement from middle school to high school is a normative transition that is typically associated with increased stress and opportunity in social and academic domains. Theoretically, this transition may reflect a turning point in terms of initiating or sharply increasing heavy alcohol use, a notion that has received little attention in the…
