Migrant children experience more stressful life events than their urban counterparts. Despite the growing evidence that stressful life events are associated with non-suicidal self-injury (NSSI), few studies have investigated this relationship using longitudinal designs. Besides, potential mediating factors have been rarely examined. This study tested the temporal relationship between stressful life events and NSSI among Chinese rural-to-urban migrant children, with depressive symptoms as the potential mediator, as well as the potential sex differences in these associations. In the present study, 279 Chinese rural-to-urban migrant children (57.3% females; M = 11.95, SD = 1.22) reported their stressful life events, depressive symptoms and NSSI a total of three times at 6-month intervals. Depressive symptoms only longitudinally mediated the relationship between stressful life events and NSSI among females. These findings provide evidence that supports the longitudinal effect of stressful life events on NSSI and the mediating role of depressive symptoms among migrant children. Moreover, there are sex differences in these longitudinal relationships.
流动儿童比城市儿童经历更多的生活压力事件。尽管越来越多的证据表明生活压力事件与非自杀性自伤（NSSI）有关，但很少有研究使用纵向设计来研究这种关系。此外，潜在的中介因素很少被检查。本研究测试了中国农村到城市流动儿童生活压力事件与 NSSI 之间的时间关系，以抑郁症状为潜在中介，并检验了这些关联中的潜在性别差异。在本研究中，279 名中国农村到城市的流动儿童（57.3%为女性；M=11.95，SD=1.22）总共在 6 个月的时间间隔内报告了 3 次生活压力事件、抑郁症状和 NSSI。抑郁症状仅在女性中纵向中介了生活压力事件与 NSSI 之间的关系。这些发现提供了支持生活压力事件对 NSSI 的纵向影响以及抑郁症状在移民儿童中的中介作用的证据。此外，这些纵向关系存在性别差异。
