Drawing on the self-system model, this study conceptualized school engagement as a multidimensional construct, including behavioral, emotional, and cognitive engagement, and examined whether changes in the three types of school engagement related to changes in problem behaviors from 7th through 11th grades (approximately ages 12-17). In addition,…

Parental involvement in education remains important for facilitating positive youth development. This study conceptualized parental involvement as a multidimensional construct--including school-based involvement, home-based involvement, and academic socialization--and examined the effects of different types of parental involvement in 10th grade on…

Adolescents are often resistant to interventions that reduce aggression in children. At the same time, they are developing stronger beliefs in the fixed nature of personal characteristics, particularly aggression. The present intervention addressed these beliefs. A randomized field experiment with a diverse sample of Grades 9 and 10 students (ages…

Issues of equality and fairness and invasion of the personal domain, 2 previously identified topic areas of adolescent sibling conflict (N. Campione-Barr & J. G. Smetana, 2010), were examined in 145 dyads ("M" [subscript first-born] = 14.97, "SD" = 1.69 years; "M" [subscript second-born] = 12.20, "SD" = 1.90 years) for their differential effects…

This longitudinal study examined how nightly variations in adolescents' study and sleep time are associated with academic problems on the following day. Participants ("N" = 535, 9th grade M[subscript age] = 14.88) completed daily diaries every day for 14 days in 9th, 10th, and 12th grades. Results suggest that regardless of how much a student…

This research examined how motivation (perceived control, intrinsic motivation, and extrinsic motivation), cognitive learning strategies (deep and surface strategies), and intelligence jointly predict long-term growth in students' mathematics achievement over 5 years. Using longitudinal data from six annual waves (Grades 5 through 10;…

To examine the development of religious identity during the teenage years, adolescents (N = 477) from Latin American, Asian, and European backgrounds completed questionnaires in the 10th, 11th, and 12th grades (10th grade age: M = 15.81, SD = 0.36). Results indicated that religious identity remained stable across high school whereas religious…

The high school transition was examined in an ethnically diverse, urban sample of 1,979 adolescents, followed from 7th to 10th grade (M[subscript age] = 14.6, SD = 0.37 in 7th grade). Twice annually, data were gathered on adolescents' perceptions of school climate, psychological functioning, and academic behaviors. Piecewise growth modeling…

Girls have caught up with boys in math course taking in high school but reasons for taking math still differ by gender. This study, therefore, investigated gender differences in the linkage between peer relations and math course taking by applying multilevel modeling to a nationally representative data set that includes peer networks and school…

A dynamic cascade model of development of serious adolescent violence was proposed and tested through prospective inquiry with 754 children (50% male; 43% African American) from 27 schools at 4 geographic sites followed annually from kindergarten through Grade 11 (ages 5-18). Self, parent, teacher, peer, observer, and administrative reports…

A social developmental framework was applied to test for the socialization of homophobic attitudes and behavior within adolescent peer groups (Grades 7-11; aged 12-17 years). Substantial similarity within and differences across groups were documented. Multilevel models identified a group socializing contextual effect, predicting homophobic…

The current study modeled developmental trajectories of ethnic identity exploration and affirmation and belonging from middle to late adolescence (ages 15-18) and examined how these trajectories varied according to ethnicity, gender, immigrant status, and perceived level of discrimination. The sample consisted of 135 urban low-income Black and…

Little is known about how adolescents' peer relations might alter whether sport participation is associated with alcohol use. Consistent with social learning theory, we found that sport participation was protective against alcohol use if these peers had low alcohol use, but athletes were likely to use alcohol if their sport friends and…

This study examined why female adolescents choose to opt out of the math pipeline during high school more often than males, which has implications for their long-term careers. (Contains 3 figures.)
