Background: Growing evidence suggests that reactive aggression is more strongly associated with youth internalizing symptoms (e.g., anxiety and depression symptoms) than proactive aggression. Detained youth are more likely to utilize both reactive and proactive functions of aggression as well as are at greater risk for developing internalizing…

There is limited research examining peer victimization (PV) experiences in early childhood, particularly during the transition from preschool to kindergarten. Given the gaps in the PV literature among this young population and the need for earlier PV prevention and intervention efforts, the current study advances the literature by examining: (1)…

The current study examined associations between proactive and reactive aggression and disciplinary actions in an academic year among middle school-age youth at Time 1 (Fall) and 6-month later (Spring) and evaluated school attachment as a moderator of these links. Findings indicated that reactive, not proactive, aggression was robustly positively…

Background: There are limited studies examining associations between callous-unemotional (CU) traits and peer victimization, with some research suggesting a positive association between these two constructs and other studies indicating no association. However, no research to date has examined these associations among justice-involved youth, and CU…

Background: A link between aggression and disciplinary actions has been established; however, specific associations between reactive and proactive functions of aggression and disciplinary actions in the elementary school setting have not been evaluated. A better understanding of links between functions of aggression and disciplinary actions could…

The purpose of the present study is to examine whether physical and relational victimization negatively impacts indicators of school climate--students' perceptions of school safety, their attachment to school, and their help-seeking behavior--and whether gender moderates these associations. Using a sample of 361 third through fifth-grade students…

Background: Sleep problems are common among adolescents and have a negative impact on functioning. A better understanding of factors that contribute to sleep problems in adolescence can help guide more effective, targeted interventions. Objective: The current study examined the associations between reactive and proactive functions of aggression…

This study examined associations between physical and relational forms of aggression and victimization and risk for willingness to engage in substance use and actual use in a sample of 231 (50% male) second- through fourth-grade students (mean age = 8.3 years). Physical aggression was more strongly associated with risk for substance use outcomes…

Although most states across the United States have enacted anti-bullying legislation, state laws vary greatly in detail and direction, leaving many school districts wondering how to best address the problem of bullying and comply with their state's legislative requirements. In response, a comprehensive, statewide training initiative was conducted…

Previous research suggests that the symptoms of oppositional defiant disorder (ODD) reflect both a general diagnostic construct and two distinct symptom dimensions, irritability and defiant behavior. Recent studies have found that these two symptom dimensions exhibit different patterns of correlates and outcomes (e.g., irritability linked to…

Competing hypotheses for explaining the role of anxiety in the relation between attention-deficit/hyperactivity disorder (ADHD) symptoms and childhood aggression were evaluated. Two studies tested whether anxiety exacerbated, attenuated, or had no effect on the relation between ADHD and aggression subtypes among psychiatrically hospitalized…

The current study examined relations between effortful control (ones ability to focus and shift attention in an adaptive manner), psychological control (caregiver attempts to manipulate the child's internal world) and proactive and reactive aggression. Participants were 69 children (54% male) ranging from 9 to 12 years of age (M = 10.35, SD =…

The current study examined relations between relational aggression, depressive symptoms, and suicidal ideation in a child clinical population. Participants included 276 children (M age = 9.55 years; 69% Male) who were admitted to a child psychiatric inpatient facility. Findings suggested that relational aggression was associated with depressive…

The current study examined whether social problems accounted for the relation between reactive aggression and withdrawn/depressed symptoms in a sample of 147 children (54.4% male) ranging from 5 to 13 years of age (M = 8.22 years) who attended a community based after-school program. Findings suggested that indeed social problems mediated the link…

Background: There is substantial evidence to suggest that aggressive behavior is associated with poor academic performance in school-aged children. However, less is known about how different subtypes of aggression are related to academic performance and what variables may account for this association. Objective: The current study examined unique…
