We investigated whether daily experiences of conflict with family and peers were associated with fluctuations in diurnal cortisol, and whether sleep buffers the associations between conflict and diurnal cortisol. A racially diverse sample of 370 adolescents (ages 11-18; 57.3% female) provided daily diaries for 5 days and saliva samples for 4 days.…

For students with significant behavior problems, difficulties with executive function (EF) and associated self-regulation are not uncommon, and middle school is a crucial period when students are at greater risk for escalating behaviors that have long-term impacts (e.g., school dropout, incarceration; Kauffman & Landrum, 2018). Therefore, in…

Family relationships play an essential role in adolescent development. When studying relationship domains (e.g., quality, conflict, communication), researchers typically rely on adolescents and their parents as informants. However, across research teams, domains, and measurement methods, researchers commonly observe discrepant estimates of family…

Biological psychiatry, like many other scientific fields, is grappling with the challenge of revising its practices with an eye towards promoting diversity, equity, and inclusivity (DEI). One arena in which much of this work will have significant impact is in developmental science generally, and the study of adolescence specifically. Adolescence…

The population of multiracial youth in the United States is expected to grow in the coming decades (exceeding 11% by 2060). In this article, we aim to convince child development researchers who do not usually examine race and ethnicity in their work to consider multiracial youth. We describe ways in which youth from more than one racial background…

Early life adversity influences the diurnal cortisol rhythm, yet the relative influence of different characteristics of adversity remains unknown. In this study, we examine how developmental timing (childhood vs. adolescence), severity (major vs. minor), and domain of early life adversity relate to diurnal cortisol rhythms in late adolescence. We…

Many prosocial behaviors involve social risks such as speaking out against a popular opinion, bias, group norm, or authority. However, little is known about whether adolescents' prosocial tendencies develop over time with their perceptions of social risks. This accelerated longitudinal study used within-subject growth-curve analyses to test the…

Research shows greater mindfulness is associated with less negative affect and more positive affect. Fewer studies have examined the mediating psychological processes linking mindfulness to these outcomes in adolescents. This three-wave, prospective longitudinal study examines rumination--the tendency to engage in repetitive and negative…

Adults play important roles in the lives of adolescents, serving as role models, sources of social support, and providers of social capital. Natural mentoring relationships (NMRs), relationships between adults and youth that rise to a level of significance for the youth, have a positive impact on youth outcomes in a number of academic,…

In Colombia, many adolescents have experienced violence related to the decades-long armed conflict in the country and have witnessed or been directly victimized by violence in their communities, often related to gang activity or drug trafficking. Exposure to violence, both political and community violence, has detrimental implications for…

Partnerships with families in education settings should emphasize their roles as active and engaged co-equal partners. However, common practices in schools are to involve families at school-based events and share information with them about their child's education in a manner that does not promote two-way interactions. The purpose of this paper is…

Although family-school engagement is important across child and adolescent development, most research, programs, and policies have focused primarily on elementary students and contexts. The current study extends beyond elementary settings by exploring the unique and shared contributions of developmental context on family-school engagement (i.e.,…

Social-emotional learning (SEL) and character education are important components of adolescent development. In this study, we evaluated a randomized controlled trial of CharacterStrong, a curriculum that combines SEL and character education that included 1609 students and 242 teachers across 14 schools. This study applied baseline target…

The assessment of psychosocial strengths in children and adolescents has predominately focused on the measurement of single traits and constructs, such as grit (Christopoulou, Lakioti, Pezirkianidis, Karakasidou, & Stalikas, 2018), optimism (Oberle, Guhn, Gadermann, Thomson, & Schonert-Reichl, 2018), hope (Pedrotti, 2018), and gratitude…

Puberty is often implicated in the onset or exacerbation of psychopathology during adolescence, and pubertal timing and tempo have emerged as important predictors of wellbeing. In the psychosocial literature there is a tendency to view individual differences in the nature (timing and tempo) of pubertal development as either determined by stress…
