This study investigated the extent to which adolescent social network positions are associated with the risk of lifetime daily smoking and nicotine dependence (ND), and whether these associations differ by gender. Using data from the National Longitudinal Study of Adolescent to Adult Health (N = 6,267), this study estimated multinomial logistic…

Background: Youth involved in the U.S. child welfare system (CWS) are at risk for mental health problems, including suicidal ideation (SI). However, the relationship between preteen suicidal ideation and academic outcomes has not been considered. Methods: This study uses data from two nationally representative longitudinal surveys of CWS-involved…

It is well established that successful transitions into adulthood vary greatly by numerous factors (e.g., race, gender); yet, understanding of ways that disability-related factors shape transitions into adulthood are less clear. While individuals with disabilities, generally, often fall short of their non-disabled peers in achieving many early…

Objective: To examine the association between childhood ADHD and lifestyle risk factors (physical inactivity and high fast-food consumption) from adolescence to early adulthood. Methods: This retrospective cohort study used secondary data from Wave I to III of the National Longitudinal Study of Adolescent Health (Add Health) in a national…

Wealth ownership is a critical component of economic well-being, and wealth in early adulthood provides important clues about the trajectories along which individuals move throughout their lives. Using data from the National Longitudinal Study of Adolescent Health (Add Health), we find an association between growing up rural and adult wealth that…

Objective: To identify the young adults' perception of their weight and examine the associations between young adults' weight perception and physical activities. Participants: A total of 4,882 participants' responses were derived from the Add Health, Wave III. Method: Chi-square tests were used to examine the weight perception and multinomial…

Schools and neighborhoods are adolescents' primary environments, and each has a significant influence on their academic success. The majority of studies on educational attainment have examined the impact of a single context--either the school or the neighborhood--suggesting mixed findings on school and neighborhood effects as well as potential…

The educational attainment of siblings is highly correlated. We test for a specific type of peer effect between siblings in educational attainment: genetic nurture. Specifically, we test whether a person's educational attainment is correlated with their sibling's polygenic score (PGS) for educational attainment, controlling for their own PGS for…

Background: Despite a vast literature linking in-home firearm access to youth suicides, few studies have examined whether and how "gaining" access to household firearms shapes adolescents' development of suicidal ideation. Objective: This study examined whether gaining access to household firearms among U.S. adolescents is associated…

This study uses the National Longitudinal Study of Adolescent to Adult Health to examine the effect of childhood trauma experiences on college graduation rates. A longitudinal mediation path analysis with a binary logistic regression is performed using trauma as a mediator between race, gender, first-generation status and college completion. The…

The detection of differential item functioning (DIF) is important in psychological and behavioral sciences. Standard DIF detection methods perform an item-by-item test iteratively, often assuming that all items except the one under investigation are DIF-free. This article proposes a Bayesian adaptive Lasso method to detect DIF in graded response…

Childhood adversities tend to impact development in a cumulative way. However, extant research on childhood adversities has focused on a variable-centered approach to examine the cumulative effect of adversity. Using Latent Class Analysis (LCA) and adopting a pattern-centered approach, the authors investigate how different youth may experience…

This study examines the independent, relative, and additive associations between both parent and peer role models and longitudinal patterns of smoking across adolescence and early adulthood. An analysis of data from the National Longitudinal Study of Adolescent to Adult Health (N = 10,166) reveals at least four distinct trajectories of smoking…

The aim of this scoping review was to map and summarise research relating to school and teacher connectedness, in order to increase current understanding of the ways these terms have been conceptualised in adolescent research. Specifically, this scoping review focuses on the analysis of the actual definitions used and the ways in which school…

We apply the theory of collateral consequences and a social stress process framework to school discipline to examine whether exclusionary school discipline policies are associated with the mental health and wellbeing of adolescents who have never been suspended or expelled and whether this association varies across race/ethnicity. Data are from…
