Non-suicidal self-injury (NSSI) is a significant public health concern, with severely impacts for adolescent mental health. As awareness of the harmful effects of NSSI grows, there is an increasing emphasis on understanding the underlying mechanisms in this age group. This study explores how internalizing and externalizing issues related to…

Problematic internet use (PIU) has become a noticeable issue among adolescents, which negatively affects their physical and mental health. Previous research has noted the protective role of school climate in reducing PIU, but the underlying mechanisms need to be further explored. Based on the ecological systems theory, this study focused on the…

Objective: The secondhand effects of alcohol use (SEA) are adverse consequences caused by another's drinking. This study explored the relationship among the experience of SEAs, alcohol use, and alcohol related consequences (ARC). In addition, we examined whether coping (i.e., adaptive, maladaptive, substance use coping, maladaptive coping without…

Sexually aggressive behavior, risky-sexual behavior, and heavy episodic drinking are interrelated behavioral-health problems among college men. College men reporting these problems, relative to peers, report lower use of protective behavioral strategies (PBS), which are cognitive-behavioral, harm-reduction strategies. College men exhibiting heavy…

This preregistered, longitudinal study examined how much adolescents value and integrate their parents' and peers' attitudes into their own attitudes from early to middle adolescence. Across three waves, participants (N = 172, 91 female, 11-16 years across three waves; 439 data points) decided whether to pay money to learn their parents' or peers'…

We study the peer effects of grade retention in the context of Indiana's statewide third-grade retention policy. When a retention occurs, it changes the peer group for two cohorts: rising fourth graders who lose a peer and rising third graders who gain a peer. We identify peer effects in both cohorts by leveraging plausibly exogenous variation in…

Background: According to Self-Determination Theory (SDT), motivation is inherently present in every individual, growing from amotivation via controlled to autonomous motivation, through fulfilment of the basic psychological needs for autonomy, competence and relatedness. Peer relatedness has been found to influence motivation multimodally.…

Despite research on peer dynamics in mainstream classrooms and in mental health interventions, investigations of peer dynamics in self-contained classrooms for students with emotional and behavioral disorders (EBD) are limited. This study examined the influence of classroom behavior norms on individual behavior in a school for students with…

Researchers have identified effective instructional strategies for teaching peer imitation, including embedded classroom-based interventions. However, there is a dearth of strategies that have been effective for teaching generalization of imitation skills to novel contexts. Building on previous research, we examined the use of progressive time…

Starting from observed gender differences in educational effort and because research considers motivation to be a personal student feature, this study had two aims. First, it examined whether autonomous and controlled motivation are shared by students within a school and whether such a motivation culture is associated with the school's student…

A primary goal of this study was to examine adolescents' use of the most commonly used social media apps in the United States. An additional goal was to examine the relationship between social media use and adolescent externalizing behaviors. The moderating influences of gender and race/ethnicity also were assessed. The sample included 1,072…

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…

This tribute to Albert Bandura shows how his lifetime of work on Social Cognitive Theory (SCT) has contributed to a greater understanding of school bullying. Managing children and adolescents' problematic behavior is a major challenge for schools with reducing bullying a priority. Here, the principles of SCT relevant to school bullying are…

Cyberbullying perpetration has become an international public health concern among adolescents. Based on the general aggression model, the present study sought to examine whether deviant peer affiliation was significantly related to adolescents' cyberbullying perpetration, and whether moral disengagement mediated this association and self-control…

Using alcohol, cigarettes, and marijuana during adolescence is associated with risks, yet there is no single cause for adolescent substance use. The etiology of substance use develops over time, across multiple levels of influence. Informed by developmental perspectives, in this review, we provide an overview of biological (e.g., genetic,…
