The present study aimed to test if perceived pubertal timing was related to marijuana and alcohol use through deviant peer affiliation. Additionally, we examined if the deviant peer pathway was moderated by impulsiveness, gender, or both. Data were collected from 342 youth, most of whom had a family history of substance use disorder. Youth…

Identity research focuses on multiple processes capturing how adolescents form and maintain a sense of self. However, identity content (the "what" of identity) might impact associations between identity and the association with well-being. We examined this potential role of content (i.e., valence and life domain) in two studies, focusing…

The present study investigated the longitudinal associations of self-control and parental involvement with prosociality and internalizing problems from early to mid-to-late adolescence, within a risk and resilience and a developmental cascade framework. We used a panel design (i.e., four measurement times at 2-year intervals from 2008 onwards) to…

The cross-sectional study aimed to examine the relationships between motives for smartphone use, family satisfaction, loneliness, grade point average (GPA), and problematic smartphone use (PSU). It included 519 elementary school students aged 12-16 years (M = 13.87, SD = 1.01). The authors used the Smartphone Addiction Scale, the Smartphone Usage…

Urban adolescents experience high rates of exposure to community violence, which is associated with sleep problems. However, less is known about the prospective relationships between community violence exposure and sleep problems across adolescence. This study investigated reciprocal relationships between community violence exposure and sleep…

This study using PROSPER data (N = 977, age 11.5-age 15) investigated the longitudinal within-family associations between parent reported parental monitoring and adolescent aggression. Importantly, this study is the first one to examine parent gender and adolescent gender differences on these within-family associations. Results differed between…

Experiences of dating violence are widespread among adolescents. Therefore, increasing the understanding on the developmental antecedents is crucial. However, most existing studies involve cross-sectional designs, which poses a challenge in better understanding the developmental precursors of dating violence victimization. To address this, we…

We used latent growth curve analysis to extend research on associations between early puberty and adverse peer relations by examining the role of pubertal timing in the developmental trajectories of peer victimization and offending from early- to mid-adolescence. We made use of three-wave longitudinal data collected annually from a cohort of…

This study investigates how adolescents begin to demonstrate skills and approaches that help them pursue their aspirations. The qualitative study examined emergent forms of key indicators of adolescent thriving: the 5Cs of positive youth development and sense of purpose. Pre- and post-program interviews with 24 S2 (~seventh grade) Scottish…

Adolescent substance use is a top national public health concern with approximately 50% of youth having tried an illicit substance by the end of high school. The transition to high school is a critical point for substance use initiation. Despite this fact, there is relatively limited research looking at factors that can protect students from…

This study examined caregivers' longitudinal reports of adolescent multiracial categorization across the ages of 9.5, 10.5, and 14 years, and adolescents' reports of their own multiracial categorization at the age of 14 years. A portion of caregivers' reports of adolescent multiracial status were inconsistent across the years of the study; some…

This study aimed to investigate the differential relationship between Temperament, Executive Functioning (EF) and Media Use Motivations and the frequency of two kinds of Media Multitasking (MM) in early adolescence. Results showed differential roles of temperamental Effortful Control, Negative Affectivity and Affiliativeness in predicting academic…

Adolescent girls are more likely to experience early sexual debut than boys. However, the developmental context of their sexual behaviors is under-investigated. Using the socio-ecological model and Malawi Schooling and Adolescent Survey, we investigated factors crucial in determining the development of sexual behaviors of 416, 14-year-old girls in…

Our study examined co-occurring substance use and major depressive disorders among justice-involved adolescents to inform behavioral health services planning within U.S. criminal justice systems. We used data from the 2015-2017 administrations of the National Survey on Drug Use and Health (NSDUH), an annual survey of non-institutionalized U.S.…
