This longitudinal study tested whether sexual harassment perpetration mediates the relationship between bullying perpetration and teen dating violence (TDV) perpetration and tested moderated mediation by assessing whether the developmental pathway varies by gender among middle school-aged youth. Although TDV has been associated with bullying and sexual harassment, the developmental relationship among all three behaviors has rarely been examined, especially by gender. The data were collected from one cohort of seventh grade middle school students (N = 612) from four schools. Students were surveyed every 6 months during seventh and eighth grades for a total of four waves of data collection. Structural equation modeling (SEM) was conducted to address the study aims, consisting of three stages: measurement models, mediation, and moderated mediation (otherwise known as Contrast of Mediated Effects). Results indicate no evidence of mediation. However, in the overall model, bullying and sexual harassment both emerged as significant predictors of TDV at a later time point. Among girls, only bullying significantly predicted TDV at a later time point, and, among boys, only sexual harassment significantly predicted TDV at a later time point. Prevention programs that target bullying and sexual harassment perpetration may reduce later perpetration of TDV. Further research is needed to disentangle the temporal relationships between these aggressive behaviors among youth.
这项纵向研究检验了性骚扰行为是否在欺凌行为与青少年约会暴力（TDV）行为之间起中介作用，并通过评估这种发展路径在初中年龄段青少年中是否因性别而异来检验调节中介作用。尽管TDV与欺凌和性骚扰有关，但这三种行为之间的发展关系很少被研究，尤其是按性别进行的研究。数据来自四所学校的一个七年级学生队列（N = 612）。在七年级和八年级期间，学生每6个月接受一次调查，总共进行了四轮数据收集。采用结构方程模型（SEM）来实现研究目的，包括三个阶段：测量模型、中介作用和调节中介作用（也称为中介效应对比）。结果表明没有中介作用的证据。然而，在总体模型中，欺凌和性骚扰在稍后的时间点均成为TDV的显著预测因素。在女孩中，只有欺凌在稍后的时间点显著预测了TDV，而在男孩中，只有性骚扰在稍后的时间点显著预测了TDV。针对欺凌和性骚扰行为的预防项目可能会减少日后TDV行为的发生。需要进一步研究来理清这些青少年攻击性行为之间的时间关系。
