School violence

A two-group predictive discriminant analysis was used to develop a model to predict youth gang activity among students in an urban school district in south central United States. The predictors were selected from age, race, gender, grade repeats, reading comprehension achievement test scores, and changes in school and school district (uprootedness). Data were obtained from elementary school records of 285 grade nine students (151 male and 134 female) in two junior high schools. Ethnic minorities comprised 75.4% of the sample. Gang involvement data were provided by the school district security department. Data were analyzed using SPSS-X and a FORTRAN computer program by Morris and Meshbane (1995). All possible subsets of predictor variables were examined using leave-one-out cross-validation accuracy estimates. Although no models classified both gang and nongang students with greater accuracy than proportional chance expectations, a model consisting of gender, grade repeats, and school and school district changes (uprootedness) yielded significant classification accuracy for gang students, (z = 12.07, p <.05).

Peer aggression and bullying are significant problems for children in American schools. While a large body of research has been conducted in this area, none to date has examined the combined roles of temperament (behavioral activation system, or BAS, and behavioral inhibition system, or BIS), and empathy in predicting participation in bullying interactions. Previous research has found that low empathy facilitates aggressive behavior, while high empathy inhibits it, and has linked poor emotion regulation to conduct disorders. Thus, if these factors can predict behaviors towards peers, they may also predict (independently and in combination) involvement in bullying, specifically the roles assumed in those interactions - that is: bully, victim, bully-victim (a child who is both bully and victim), or defender/protector. The present study tested 226 middle school students on a measure of empathy (Interpersonal Reactivity Index), and a measure of temperament (BIS/BAS Scales). The students also completed a Peer Nomination Inventory to identify children who were aggressive toward others, victimized by peers, and/or protected peers from bullies. Although not all predictions were supported, results showed that certain sub-components of empathy, such as empathic concern (affective empathy) and personal distress (a measure of emotion regulation) predicted the behavior of "pure bullies" (bullies who are not themselves victimized), but not of other aggressive children such as bully-victims. High BAS drive and low BIS were significant predictors of aggressive behavior, and BAS reward responsiveness predicted protective behavior. Victimized children had higher fantasy (ability to identify with fictional characters) and lower perspective-taking (cognitive empathy) skills, and tended not to have overlapping characteristics and behaviors with protective children.
