The present study identified longitudinal trajectories of revenge goals in a sample of at-risk youth (N = 240; 63.3% male) followed from fourth grade through seventh grade. Three revenge goal trajectory groups were identified: a low-stable group, an increasing group, and a decreasing group. The increasing and decreasing groups were initially more…

The development of Physical Dating Aggression from the age of 16 to 18 years was investigated in relation to time-invariant predictors (gender, parental education, family composition, number of partners) and to time-varying effects of delinquent behavior and perception of victimization by the partner. The sample consisted of 181 adolescents with a…

This project examined the unique predictive validity of parent ratings of toddler-age aggression, oppositionality, inattention, and hyperactivity-impulsivity to academic achievement at school-age in a sample of 566 high-risk children and families. The study also investigated potential indirect effects of the Family Check-Up on school-age academic…

This research examined two pathways through which depressive symptoms contribute to low social status (i.e., neglect and rejection) within the peer group over time: (a) depressive symptoms promote socially helpless behavior and consequent neglect by peers; and (b) depressive symptoms promote aggressive behavior and consequent rejection by peers.…

This study examined self-reports of social victimization and parent reports of adjustment for a sample followed from fourth through seventh grades. Different patterns of social victimization experiences were identified; of the 153 students (79 girls) with complete data, 24% reported chronic social victimization, 23% reported transient experiences…

The purpose of this study was to examine the association between hypothalamic-pituitary-adrenal axis (HPA-axis) reactivity and proactive and reactive aggression in pre-pubertal children. After a 30-min controlled base line period, 73 7-year-old children (40 males and 33 females) were randomly assigned to one of two experimental tasks designed to…

The consequences of aggression on problem course and suicide risk were examined in 270 acutely suicidal adolescents (ages 12-17 years; 184 girls). Participants were assessed during psychiatric hospitalization (T1), 6-months post-hospitalization (T2), and 15 or more months post-hospitalization (T3). Study variables included self- and…

This study assessed the role of grandiosity and justification of violence cognitive schemas as predictors of adolescents' antisocial behavior. The 974 Spanish adolescents (457 girls and 517 boys, aged between 14 and 18 years) were assessed at the beginning of the school year and at follow-up 6 months later. They completed measures of aggressive…

A multi-informant and multi-measure short-term longitudinal study of the association between subtypes of aggression and peer victimization was conducted in an early childhood sample (M = 44.36 months; SD = 11.07; N = 120). Observational and teacher report measures demonstrated appropriate reliability and validity as well as stability across an…

This study examined concurrent and longitudinal associations between peer deviance, parenting practices, and conduct and oppositional problems among young girls ages 7 and 8. Participants were 588 African American and European American girls who were part of a population-based study of the development of conduct problems and delinquency among…

It has been proposed that aggressive behavior may result from unrealistically positive self-evaluations that are disputed by others (Baumeister, Smart, & Boden, 1996). The present three studies tested this proposition concurrently and longitudinally for the domain of self-perceived social competence (SPSC) in 3-6th grade children on two…

This study investigated associations between maternal prenatal smoking and physical aggression (PA), hyperactivity-impulsivity (HI) and co-occurring PA and HI between ages 17 and 42 months in a population sample of children born in Quebec (Canada) in 1997/1998 (N=1745). Trajectory model estimation showed three distinct developmental patterns for…

Although great strides have recently been made in our understanding of relational aggression and its consequences, one significant limitation has been the lack of prospective studies. The present research addressed this issue by identifying and assessing groups of relationally aggressive, physically aggressive, relationally plus physically…

Comorbidity between antisocial behavior and depression in adolescence is widely recognized. This paper examines whether links with depressed mood differ among three subtypes of antisocial behavior: oppositionality, physical aggression and delinquency. In addition we examine two possible contributors to these links: negative life events that are…

The current study tests whether the presence of callous-unemotional (CU) traits designates a group of children with conduct problems who show an especially severe and chronic pattern of conduct problems and delinquency. Ninety-eight children who were selected from a large community screening of school children in grades 3, 4, 6 and 7 were followed…
