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…

This study used a cross-lagged panel analysis to explore the effect of impulsivity and academic achievement on the development of suicidal ideation in adolescents using three-time assessments with an interval of 6 months. A total of 211 adolescents (104 boys, 107 girls with a mean age of 13.62 ± 0.68 years in the third assessment) completed the…

The purpose of the present study was to identify the patterns of Internet addiction in early adolescents and their associated protective factors in order to prevent and/or ameliorate internet addiction as early as possible. A 2-year longitudinal study was conducted among 621 Chinese early adolescents. Latent class and latent transition analyses…

The purpose of this study was to determine whether bullying perpetration in early adolescence is capable of predicting delinquency 1 year later. Nine control variables were included in a regression analysis of the bullying-delinquency relationship in 1,001 schoolchildren (X-bar age = 12.97 years). The nine control variables (age, sex, race, social…

The current study explored early adolescent child-level predictors (physical aggression, impulsivity, empathy) and contextual-level predictors (peer deviance, neighborhood dangerousness) of violent and nonviolent antisocial behavior (AB) in late adolescence. Additionally, we tested the moderating role of rejecting parenting on these associations…

In a previous study, reactive criminal thinking or cognitive impulsivity mediated the relationship between parental knowledge and delinquency. This study sought to determine whether cognitive impulsivity also mediated the relationship between parental knowledge and childhood aggression. A path analysis was performed on a sample of 438 early…

A growing body of research has acknowledged the heterogeneity of subclinical social anxiety, identifying a subgroup of individuals who exhibit high levels of impulsivity. In a sample of Swedish early adolescents (N=2,509, M[subscript age]=13.64; 52.8% girls), we conducted latent transition analyses (LTA) to identify four classes of subclinical…

This study's purpose was to examine the relations among future orientation, self-esteem, and later adolescent risk behaviors, and to compare two mediational models involving self-esteem versus future orientation as mediators. An ethnically diverse sample of 12- to 14-year-olds (N = 862, 54% female, 53% ethnic minority) was assessed longitudinally.…

Early adolescents vary in their susceptibility to peer influence on delinquency. However, it is still less clear which factors explain this variation and how these factors relate to each other. In this study, 10 factors that may moderate peer influence were investigated. A sample of 868 participants was followed across six occasions from seventh…

Immigrant youth are at risk of experiencing harassment in school; however, we have only limited understanding of what makes youth harass their peers on ground of their ethnic origin. To address this major limitation, we examined (a) whether youth's negative attitudes toward immigrants impact their engagement in ethnic harassment over time and (b)…

The goal of this study was to test if both effortful control (EC) and impulsivity, a reactive index of temperament, uniquely predict adolescents' academic achievement, concurrently and longitudinally (Time 1: "N" = 168, X-bar[subscript age] = 12 years). At Time 1, parents and teachers reported on students' EC and impulsivity.…
