ABSTRACT

Developmental trajectories of bullying perpetration were examined across 5 waves of longitudinal panel data among Midwestern middle school students. This study explained an unobserved heterogeneity of subgroups, each having the similar pattern of trajectories and investigated antecedents and consequences of class membership. Growth-mixture modeling yielded 4 groups: (1) Chronic, (1.2%), (2) High Declining (6.2%), (3) Middle School Peak (8.1%), and (4) Low (84.4%). The overall results revealed that strain variables were found to be significant in the Chronic, High Declining, and Middle School Peak groups. The probability of the Chronic and High Declining groups was high among students with higher impulsivity. Peer delinquency and anger were found to be significant in all three groups. Members of the Chronic group were at the highest risk of sexual harassment and teen dating violence.

摘要

在中西部中学生的5次纵向面板数据调查中，研究了欺凌行为的发展轨迹。这项研究解释了子群的不可观察的异质性，每个子群具有相似的轨迹模式，并研究了类成员的前因和后果。生长混合模型分为4组：（1）慢性（1.2％），（2）高下降（6.2％），（3）中学高峰（8.1％）和（4）低（84.4％）。总体结果表明，在慢性，高下降和中学高峰期组中，应变变量具有重要意义。冲动性较高的学生中，慢性和高下降组的可能性较高。在这三组中，同龄人的犯罪和愤怒都很明显。长期小组成员遭受性骚扰和青少年约会暴力的风险最高。
