The temporal ordering of depression, aggression, and victimization has important implications for theory, policy, and practice. For a representative sample of high school students (Grades 7-10; N = 3,793) who completed the same psychometrically strong, multiitem scales 6 times over a 2-year period, there were reciprocal effects between…

While both outsiders and defenders have antibullying attitudes, only defenders have the reputation to defend victims. However, outsiders--despite their reputation of avoiding involvement in bullying--do receive some defender nominations and thus defend victims at least occasionally. This study investigated the relationship between these behavioral…

The current study further establishes the reliability and validity of the Bullying Participant Behaviors Questionnaire (BPBQ), a self-report survey that allows for an examination of participation in various bullying participant role behaviors including bully, assistant to the bully, victim, defender of the victim, and outsider. The study included…

Student perceptions of school climate represent the ways students feel about the school environment. These include perceptions regarding safety, teaching and learning, and relationships within the school. It has been found that student perceptions of school climate are positively correlated with academic achievement (Brookover et al., 1978), and…

This study examined the relations between multiple types of peer victimization, affective reactivity to victimization, and academic achievement. Participants (179 fifth-grade boys and girls) completed repeated daily measures of peer victimization and negative affect; a standardized measure of achievement was collected concurrently. The daily…

The study aimed to develop the Homophobic Bullying Scale and to investigate its psychometric properties. The items of the Homophobic Bullying Scale were created to measure high school students' bullying behaviors motivated by homophobia, including verbal bullying, relational bullying, physical bullying, property bullying, sexual harassment, and…

Researchers investigating school-level approaches for bullying prevention are beginning to discuss and target school climate as a construct that (a) may predict prevalence and (b) be an avenue for school-wide intervention efforts (i.e., increasing positive school climate). Although promising, research has not fully examined and established the…

Five independent studies were used to test the hypothesis that a reliable 2-factor structure underlies the Reactive-Proactive Aggression Questionnaire (RPQ) items and that the 2 scales show distinct patterns of association with personality and bullying behavior measures. Study 1 (N = 1,447) gave evidence of a clear 2-factor structure of RPQ items…
