Granger models are popular when it comes to testing hypotheses that relate series of measures causally to each other. In this article, we propose a taxonomy of Granger causality models. The taxonomy results from crossing the four variables Order of Lag, Type of (Contemporaneous) Effect, Direction of Effect, and Segment of Dependent Series…

This study examined the reciprocal longitudinal relations between homophobic attitudes and homophobic bullying at school. Furthermore, the study also assessed the roles of exposure to homophobic bullying at school, homophobic language at home, and previous social interaction with individuals who identify as lesbian, gay, bisexual, or transgender…

Bullying is grounded in the interactions between an individual and complex social-ecological systems. Therefore, bullying involvement is not just confined to the classroom or school. Recent research suggests that sibling aggression may be a predictor for peer-level aggression. These findings may be more relevant for students with disabilities…

Although social difficulties have been identified as sequelae of children's experiences with interparental conflict and insecurity, little is known about the specific mechanisms underlying their vulnerability to social problems. Guided by emotional security theory, this study tested the hypothesis that children's emotional insecurity mediates…

We evaluated the extent to which the externalizing behavior construct is self-organizing in the first 2 years of life. Based on dynamic systems theory, we hypothesized that changes in physical aggression, defiance, activity level, and distress to limitations would each be predicted by earlier manifestations of one another. These hypotheses were…

Extending John Bowlby's hypothesis that dysfunctional anger is a predictable outcome of insecure attachments to parents, this study investigated the relationship between current parent-adolescent attachment and both the experience and expression of anger. Participants included 776 students (379 boys and 397 girls) in grades 8-12. As predicted by…

Research has widely documented the over-representation of office disciplinary referrals (ODRs) among specific student groups (e.g., African American, boys). Despite extant research documenting individual-level predictors of ODRs, few studies have accounted for the nested structure of the settings in which these events occur. Guided by critical…

Using a sample of 767 children (403 girls, 364 boys), this study aimed to (a) identify groups with distinct trajectories of peer victimization over a 6-year period from primary school through the transition to secondary school, and (b) examine the associated personal (i.e., aggression or internalizing problems) and familial (family status,…

The present longitudinal study examined how relationships with teachers and peers jointly shape the development of children's behavioral engagement in late elementary school. A sample of 586 children (46% boys; M[subscript age] = 9.26 years at Wave 1) was followed throughout Grades 4, 5, and 6. A multidimensional approach was adopted,…

Background: Aggression is one of the more stable characteristics of child and adolescent development, and violent behavior in early adulthood is often foreshadowed by aggressive behavior in childhood and early adolescence. Considerable evidence has linked coercive family interactions to aggressive behavior in childhood, but less research has been…

Peer victimization is a known risk factor for various forms of maladjustment; however, the specific type of maladjustment may depend on individual differences in youth. This 2-wave longitudinal study examined the hypothesis that social approach-avoidance motivation, together with sex, would moderate the contribution of 3rd-grade victimization to…

Substantial evidence suggests that rumination is an important vulnerability factor for adolescent depression. Despite this, few studies have examined environmental risk factors that might lead to rumination and, subsequently, depression in adolescence. This study examined the hypothesis that an adverse family environment is a risk factor for…

This study examined the role of peer acceptance and perceived popularity in bullying and victimization in early adolescent peer groups. Peer acceptance is the degree to which adolescents are well liked by their peers; perceived popularity indicates visibility, dominance, and prestige. It was hypothesized that acceptance negatively predicts…

This study examined effects of type of and cumulative burden of childhood adversities on bullying and cruelty to animals in the United States. Data were derived from Waves I and II of the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample of U.S. adults. Structured psychiatric interviews were…

Although there is considerable evidence that culture-related factors are associated with aggressive behavior, their effect on the development of conduct problems (CP) has been insufficiently studied. This study focused on adherence to honor code (AHC), defined by the endorsement of honor culture attitudes at the identity narrative level of…
