The Development of LGBTQ Other Group Orientation and Its Relation to Psychological and Social Well‐Being Among Cisgender Heterosexual Adolescents
Introduction Given the marked rise in the number of adolescents openly identifying as lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ), there are more opportunities for peer interactions and friendships between cisgender heterosexual and LGBTQ adolescents. Yet, little is known about the development of cisgender heterosexual adolescents' openness toward engaging with LGBTQ individuals and how this relates to their own well‐being.…
The development of gender centrality and private regard and its relation to psychological and social well‐being among cisgender adolescents
Although adolescence is theorized to be a critical period for identity development, little is known about how gender identity, specifically gender centrality and private regard, develops among adolescents. The current study assessed trajectories of gender centrality and private regard across five waves of data from Grade 9 through Grade 10 among cisgender adolescents from the United States ( M age = 14.1 years; N = 374; SD = 0.41, 139 boys and 23…
Longitudinal pathways linking peer victimization to academic efficacy in adolescence
Although past research links greater peer victimization to poorer academic achievement, much less is known about if or how peer victimization contributes to adolescents’ academic efficacy, a potentially malleable predictor of academic success. Informed by the biopsychosocial framework of sleep that emphasizes the interplay of interpersonal dynamics and bioregulatory processes in shaping developmental outcomes, the current study investigated pathw…

Trajectories of adolescent friendship stability
Although the protective effects of high-quality friendships in adolescence are well-established, less is known about how adolescents' friendship stability changes over time and whether adolescents' friendship stability shapes health outcomes. Using six waves of data from 388 adolescents ( M age = 14.05, SD = 0.41; 61% female), the current study examined trajectories of friendship stability across high school and assessed whether friendship stabil…
Friendships in flux
Although maintaining stable friendships is an important developmental task for adolescents, there is limited understanding of whether adolescents' friendships vary from day to day and predict changes in emotional well-being. Therefore, the current daily diary study aimed to characterize the day-to-day consistency of adolescents' close friendships and investigate whether feeling close to the same friends from 1 day to the next (daily friend contin…
Perceptions of STEM Barriers in Adolescence
This 2-year longitudinal study examines the relations between math and science interest, STEM identity, and perceptions of STEM barriers in 280 (68% female; M age = 15.27) adolescents in the United States and the United Kingdom. Structural equation models indicated that higher math interest at time 1 was positively associated with overall STEM identity at time 2, and greater STEM identity at time 2 was related to fewer perceptions of barriers to …
Early Adolescent Cherokees' Reports of Stereotypes About Native Americans
Given the paucity of research on ethnic-racial stereotypes from the child's perspective, we explored the content of Cherokee adolescents' perceptions of stereotypes about Native Americans, as well as grade-level and school-type differences in the frequency of stereotype reports. The sample comprised 212 Cherokee adolescents ( M age = 12.7 years; Grades 6-8) enrolled in a tribal middle school or one of two public middle schools. Adolescents were a…
To heal, grow, and thrive
A focus on positive child development among Indigenous children has largely been absent from developmental science. In this special section of Child Development, we sought to address continuing inequity in representation and valuing Indigenous knowledge and voices by soliciting articles that identified cultural and strengths-based factors Indigenous children, youth, and families cultivate and leverage to promote positive development. In this intr…
