Sleeping through the ages
Sleep is a fundamental domain of development and has important implications for other key aspects of adaptation. Little is known about normative changes in sleep across adolescence and emerging adulthood and whether the change is linear or nonlinear. We examined growth trajectories of sleep across 9 years of development and individual differences in trajectories according to participants' race/ethnicity and sex assigned at birth. During each wave…
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…
Connecting adolescent friendships to physical health outcomes
Friendships are developmentally significant peer relationships that meaningfully contribute to adolescent adjustment. Despite extensive evidence that friendships contribute to adolescents’ psychological well‐being and mental health, less is known about the connections between adolescents’ friendships and physical health outcomes. Therefore, the current review synthesizes a growing body of research examining associations between adolescent friends…
Daily Fluctuations in Adolescents’ Perceived Friend Dominance and Friendship Clout
The Power Dynamics of Friendship
On shaky grounds
INTRODUCTION: Although prior research has considered how friendship quality or quantity influence peer victimization risk and vice versa, considerably less is known about how friendship instability (i.e., high levels of friend turnover) and peer victimization may be related to each other across time. METHODS: = 14.05; 60.60% female; 35.8% male; 1.8% non-binary; 1.9% trans/unsure/something else) across 3-month intervals spanning one school year. U…
Daily academic satisfaction and ethnic/racial identity of Asian American adolescents
The purpose of the current study was to examine the association between daily academic satisfaction and ethnic/racial identity of Asian American adolescents. Based on ecological systems theory and social comparison theory the moderating roles of objective and subjective peer diversity at school in this association were also examined. Daily diary and survey responses of 102 Asian American adolescents were included in this study (Age: M =15.26, SD …
