Abstract：
BACKGROUND: Poly-victimization is more detrimental to adolescents\' physical and mental health than is a single type of victimization. However, there has been limited research on the trajectory of poly-victimization among Chinese adolescents.
OBJECTIVE: Identify the different developmental trajectories of poly-victimization among Chinese adolescents over time and examine the influencing factors of poly-victimization trajectories.
METHODS: Data from four surveys conducted between 2020 and 2022, encompassing a cohort of 319 adolescents who had experienced poly-victimization, were utilized to identify their developmental trajectories via group-based trajectory modeling. Potential influencing factors were screened and compared using ANOVA or chi-square tests, while factors affecting the developmental trajectories of poly-victimization were analyzed through multinomial logistic regression.
RESULTS: We identified three poly-victimization trajectories among adolescents: increasing poly-victimization (n = 39, 12.2 %), relieved poly-victimization (n = 228, 71.5 %), and fluctuating poly-victimization (n = 52, 16.3 %). Our findings indicate that boys, and those with poor class grade ranking, a lower level of parental education, lower household economy, smoking, drinking, suicide attempts, and suicide ideation, constitute the primary focus for the prevention and treatment of poly-victimization.
CONCLUSIONS: We identified three poly-victimization trajectories, highlighting a significant heterogeneity in poly-victimization development. Understanding the characteristics of these developmental trajectories is crucial for realizing the dynamics of different poly-victimization subgroups and informing effective interventions.

摘要：
背景：多重受害比单一类型的受害更不利于青少年的身心健康。然而,关于中国青少年多重受害轨迹的研究有限。
目的：确定中国青少年多重受害的不同发展轨迹，并考察多重受害轨迹的影响因素。
方法：来自2020年至2022年之间进行的四项调查的数据，包括319名经历过多重受害的青少年，通过基于组的轨迹建模来识别它们的发展轨迹。采用方差分析或卡方检验对潜在影响因素进行筛选和比较，同时通过多项逻辑回归分析了影响多重受害发展轨迹的因素。
结果：我们确定了青少年的三个多重受害轨迹：增加多重受害（n=39，12.2％），缓解多重受害(n=228，71.5%)，和波动的多重受害(n=52，16.3%)。我们的研究结果表明，男孩，和那些班级成绩差的人，较低水平的父母教育，较低的家庭经济，吸烟,饮酒,自杀未遂,和自杀的想法，构成预防和治疗多重受害的主要重点。
结论：我们确定了三个多重受害轨迹，强调了多受害发展中的显著异质性。了解这些发展轨迹的特征对于实现不同多受害性子组的动态并告知有效的干预措施至关重要。
