To identify factors in adolescence that predict the onset of sexual violence in adolescence and young adulthood. Data were analyzed from six survey waves of the longitudinal Growing up with Media Study (2008-2018) conducted in the USA. Participants were 778 youth 13-18 years old at baseline, who completed online surveys assessing sexual violence…

The goal of the present study was to replicate Burt et al. (2009) and Hou et al. (2013) findings by determining the contribution of peers' deviance to changes in participants' (monozygotic [MZ] twins') self-reported delinquency from mid- to late adolescence while controlling for possible gene-environment correlations (rGE) through the use of the…

This study examines the effect of race/ethnicity, immigrant status and the role of school belonging on the academic achievement of Mexican, Filipino, and white students. We focus on school belonging and peer influences in concert with immigrant generational status and family income to predict students' academic achievement at the end of 9th grade.…

Being surrounded by peers who are accepting of aggression is a significant predictor of the development and persistence of aggression in childhood and adolescence. Whereas past research has focused on social reinforcement mechanisms as the underlying processes, the present longitudinal study analysed the role of external control beliefs as an…

Youths who have deviant and delinquent friends are more likely to engage in delinquency. Interestingly, most quantitative studies of the association between deviant peers and deviant behavior have assumed that all peer connections have similar effects. Yet, it is possible that peer influence may vary depending on the characteristics of peers.…

This investigation examines the spread of problem behaviors (substance use and delinquency) between twin siblings. A sample of 628 twins (151 male twin pairs and 163 female twin pairs) drawn from the Quebec Newborn Twin Study completed inventories describing delinquency and substance use at ages 13, 14, and 15. A 3-wave longitudinal actor-partner…

Expectations about alcohol's effects and perceptions of peers' behaviors and beliefs related to alcohol use are each shown to strongly influence the timing of drinking onset during adolescence. The present study builds on prior work by examining the conjoint effects of within-person changes in these social-cognitive factors on age of adolescent…

A high school education prepares young people to participate positively in the economy and in civic life, among other positive life outcomes. However, nearly one in five American high school students does not graduate from high school on time, if ever. Progress has been made on understanding why students fail to complete high school and on raising…

As special education inclusion policies become more widespread, classroom compositions are changing in ways that affect all students. The present study fills a critical gap in the literature by documenting the extent to which having a classmate with an emotional disturbance (ED) is linked to kindergarteners' absences. Because having a classmate…

Using participants from an 1-and-1/2-year longitudinal study of smoking socialization (N = 709), we examined peer smoking, and implicit and explicit attitudes on smoking initiation among initial nonsmoking adolescents. We also tested whether implicit and explicit attitudes mediated the effect of peer smoking on smoking initiation, and whether…

Early adolescence is a dynamic period for the development of alcohol appraisals (expected outcomes of drinking and subjective evaluations of expected outcomes), yet the literature provides a limited understanding of psychosocial factors that shape these appraisals during this period. This study took a comprehensive view of alcohol appraisals and…

The objective of this short-term longitudinal study was to examine individual versus classroom peer effects of grit on later individual literacy achievement in elementary school. The dual language learner, largely Latina/o sample included students from the 3rd through the 5th grades. Participants completed a literacy achievement performance task…

The Motivation for Educational Attainment (MEA) questionnaire, developed to assess facets related to early adolescents' motivation to complete high school, has a bifactor structure with a large general factor and three smaller orthogonal specific factors (teacher expectations, peer aspirations, value of education). This prospective validity study…

Adolescence is a vulnerable period for the initiation and peak of many harmful risk-taking behaviors such as smoking, which is among the most addictive and deadliest behaviors. Generic metatheories like the theory of triadic influence (TTI) suggest that interrelated risk factors across multiple domains (i.e., intrapersonal and…

Longitudinal links between early childhood temperament, maternal sensitivity, and adolescents' adjustment have been proposed and found in several longitudinal studies, but the mechanisms of influence have not been explored. The authors examined the paths from maternal sensitivity and temperament in early childhood to adolescents' prosocial,…
