This study examined early adolescent romantic "churning," defined here as having a large number of boyfriends/girlfriends by age 13, as a problematic marker likely to predict hostility, abuse, and avoidance during conflict in later relationships. A sample of 184 adolescents was followed through age 24 to assess predictions of hostility,…

Valid measurement of how students' experiences in secondary school classrooms lead to gains in learning requires a developmental approach to conceptualizing classroom processes. This article presents a potentially useful theoretical model, the Teaching Through Interactions framework, which posits teacher-student interactions as a central driver…

The long-term import of a fundamental challenge of adolescent social development--establishing oneself as a desirable peer companion while avoiding problematic behaviors often supported within peer groups--was examined in a community sample of 184 adolescents, followed from ages 13 to 23, along with parents, peers, and romantic partners. The…

This study tests the impact of a randomly assigned professional development coaching intervention (MyTeachingPartner-Secondary; MTP-S) on teacher projections of their students' educational attainment. Results indicate that students who report more behavior problems in the Fall of the academic year are projected by teachers to have lower future…

Student engagement is an important contributor to school success, yet high school students routinely describe themselves as disengaged. Identifying factors that alter (increase) engagement is a key aspect of improving support for student achievement. This study investigated students' perceptions of autonomy, teacher connection, and academic…

Adolescent ego-development trajectories were related to close-relationship outcomes in young adulthood. An adolescent sample completed annual measures of ego development from ages 14 through 17. The authors theoretically determined and empirically traced five ego-development trajectories reflecting stability or change. At age 25, the sample…

This study examined ways in which adolescent attachment security is manifest in qualities of the secure base provided by mother-adolescent relationships among at-risk ninth- and tenth-graders. Findings suggest that security is closely connected to the mother-adolescent relationship via a secure-base phenomenon, in which the teen can explore…

Although success in managing evolving peer relationships is linked to critical adolescent outcomes, little is known about the specific factors that lead to success or failure in peer relationship development across adolescence. This longitudinal study examines the role of adolescents' level of ego development as a predictor of the future course of…

Seventy-seven adolescents in 2-parent families and their parents were observed in a revealed-differences interaction task when the adolescents were age 14, and the adolescents' ego development and self-esteem were assessed at both age 14 and 16. Adolescents' displays of autonomy and relatedness were strongly related to concurrent measures of ego…
