This study identified classes of developmental trajectories of physical dating violence victimization from grades 8 to 12 and examined theoretically-based risk factors that distinguished among trajectory classes. Data were from a multi-wave longitudinal study spanning 8th through 12th grade (n = 2,566; 51.9 % female). Growth mixture models were used to identify trajectory classes of physical dating violence victimization separately for girls and boys. Logistic and multinomial logistic regressions were used to identify situational and target vulnerability factors associated with the trajectory classes. For girls, three trajectory classes were identified: a low/non-involved class; a moderate class where victimization increased slightly until the 10th grade and then decreased through the 12th grade; and a high class where victimization started at a higher level in the 8th grade, increased substantially until the 10th grade, and then decreased until the 12th grade. For males, two classes were identified: a low/non-involved class, and a victimized class where victimization increased slightly until the 9th grade, decreased until the 11th grade, and then increased again through the 12th grade. In bivariate analyses, almost all of the situational and target vulnerability risk factors distinguished the victimization classes from the non-involved classes. However, when all risk factors and control variables were in the model, alcohol use (a situational vulnerability) was the only factor that distinguished membership in the moderate trajectory class from the non-involved class for girls; anxiety and being victimized by peers (target vulnerability factors) were the factors that distinguished the high from the non-involved classes for the girls; and victimization by peers was the only factor distinguishing the victimized from the non-involved class for boys. These findings contribute to our understanding of the heterogeneity in physical dating violence victimization during adolescence and the malleable risk factors associated with each trajectory class for boys and girls.
本研究旨在确定从 8 年级到 12 年级期间身体约会暴力受害的发展轨迹类别，并检验理论上区分轨迹类别的风险因素。数据来自一项跨越 8 至 12 年级的多波纵向研究（n=2566；51.9%为女性）。增长混合物模型分别用于确定女孩和男孩身体约会暴力受害的轨迹类别。逻辑回归和多项逻辑回归用于确定与轨迹类别相关的情境和目标脆弱性因素。对于女孩，确定了三个轨迹类别：低/非参与类；中度类别，其中受害程度在 10 年级之前略有增加，然后在 12 年级下降；高类别，其中受害程度在 8 年级较高，在 10 年级大幅增加，然后在 12 年级下降。对于男孩，确定了两个类别：低/非参与类和受害类，其中受害程度在 9 年级之前略有增加，在 11 年级下降，然后在 12 年级再次增加。在双变量分析中，几乎所有的情境和目标脆弱性风险因素都将受害类别与非参与类别区分开来。然而，当所有风险因素和控制变量都纳入模型时，饮酒（情境脆弱性）是将中度轨迹类别与女孩非参与类别区分开来的唯一因素；焦虑和被同龄人受害（目标脆弱性因素）是将高类别与女孩非参与类别区分开来的因素；而被同龄人受害是将受害类别与男孩非参与类别区分开来的唯一因素。这些发现有助于我们理解青少年时期身体约会暴力受害的异质性以及与男孩和女孩每个轨迹类别的可塑风险因素。
