INTRODUCTION Although prior research has considered how friendship quality or quantity influence peer victimization risk and vice versa, considerably less is known about how friendship instability (i.e., high levels of friend turnover) and peer victimization may be related to each other across time. METHODS Survey data were collected from 9th grade students (N = 388; Mage  = 14.05; 60.60% female; 35.8% male; 1.8% non-binary; 1.9% trans/unsure/something else) across 3-month intervals spanning one school year. Using cross-lagged panel modeling, this study investigated cross-lagged longitudinal associations between friendship instability and peer victimization utilizing three waves of data collected across one academic year. RESULTS Adolescents experiencing greater peer victimization at the beginning of the school year were more likely to experience friendship instability by the end of the school year. However, friendship instability at the beginning of the school year was unrelated to subsequent peer victimization. CONCLUSION Peer victimized adolescents are less likely than their nonvictimized peers to maintain stable friendships over time. Findings suggest that adolescents who are victimized by peers after transitioning to high school may have difficulty maintaining friendships.

理由不充分：同伴受害预示着整个九年级的友谊不稳定。

引言 虽然先前的研究已经考虑了友谊的质量或数量如何影响同伴受害风险，反之亦然，但对于友谊的不稳定性（即，高水平的朋友流动率）和同伴受害如何随着时间的推移相互关联，我们知之甚少。方法 调查数据是从 9 年级学生（N = 388；Mage = 14.05；60.60% 女性；35.8% 男性；1.8% 非二元；1.9% 跨性别/不确定/其他）中收集的，跨越一学年的 3 个月间隔. 使用交叉滞后面板模型，本研究利用跨一学年收集的三波数据调查了友谊不稳定性和同伴受害之间的交叉滞后纵向关联。结果 在学年开始时遭受同伴伤害的青少年更有可能在学年结束时经历友谊不稳定。然而，学年开始时的友谊不稳定与随后的同伴受害无关。结论 与未受害的同龄人相比，受同龄人受害的青少年随着时间的推移保持稳定的友谊的可能性较小。调查结果表明，在过渡到高中后被同龄人伤害的青少年可能难以维持友谊。结论 与未受害的同龄人相比，受同龄人受害的青少年随着时间的推移保持稳定的友谊的可能性较小。调查结果表明，在过渡到高中后被同龄人伤害的青少年可能难以维持友谊。结论 与未受害的同龄人相比，受同龄人受害的青少年随着时间的推移保持稳定的友谊的可能性较小。调查结果表明，在过渡到高中后被同龄人伤害的青少年可能难以维持友谊。
