Justice sensitivity (JS), the tendency to perceive and negatively respond to alleged injustice, has been associated with a range of internalizing and externalizing problems and peer victimization; however, it remains unclear if it has an association with self-victimization. Participants (N = 769) reported on their JS longitudinally at 9–19 (T1), 11–21 (T2), and 14–22 years of age (T3). They further reported on nonsuicidal self-injury (NSSI) and illegal substance use as indicators of self-victimization as well as victimization by peers at T2 and T3. A cross-lagged latent model revealed that victim JS at T1 was positively associated with NSSI, substance use, and peer victimization at T2, and victim JS at T2 was positively associated with substance use at T3. Higher observer JS at T2 predicted higher illegal substance use at T3 and higher illegal substance use at T2 predicted higher observer JS at T3. Finally, higher peer victimization at T2 predicted less perpetrator JS at T3 in the total group. Multigroup models further revealed sex-specific effects. Our findings highlight that being sensitive to injustice, particularly the tendency to feel unfairly treated or being taken advantage of, contributes to individuals’ vulnerability to both engaging in behaviors reflecting self-victimization and being a target of peer victimization, which in turn have influences on JS.

正义敏感性（JS），即对所谓的不公正的感知和消极反应的倾向，与一系列内化和外化问题以及同伴受害有关；然而，尚不清楚它是否与自我伤害有关。参与者（N= 769) 在 9-19 (T1)、11-21 (T2) 和 14-22 岁 (T3) 纵向报告了他们的 JS。他们进一步报告了非自杀性自我伤害 (NSSI) 和非法物质使用作为自我伤害的指标以及 T2 和 T3 的同龄人受害的指标。交叉滞后的潜在模型显示，T1 的受害者 JS 与 T2 的 NSSI、物质使用和同伴受害呈正相关，T2 的受害者 JS 与 T3 的物质使用呈正相关。T2 较高的观察者 JS 预测 T3 较高的非法物质使用和较高的 T2 非法物质使用预测 T3 较高的观察者 JS。最后，在 T2 较高的同伴受害预测在整个组中 T3 的肇事者 JS 较少。多组模型进一步揭示了性别特异性效应。我们的研究结果强调，对不公正敏感，
