Non-suicidal self-injury (NSSI) is a highly serious public health problem among adolescents in China, and childhood emotional maltreatment has been found to be a risk factor for NSSI.
Little is known about the longitudinal association between childhood emotional maltreatment and NSSI as well as its underlying mediating and moderating mechanisms. Thus, we hypothesized whether sleep problems mediated the association between childhood emotional maltreatment and NSSI, and whether this indirect effect was moderated by rumination.
A total of 1987 Chinese adolescents (56.1 % males; ages 10 to 14, M = 12.32, SD = 0.53) completed self-report questionnaires regarding childhood emotional maltreatment, sleep problems, rumination non-suicidal self-injury (NSSI) in three waves.
Structural equation model was used to test a moderated mediation model, with gender, age and socioeconomic status and baseline measures as covariates.
Childhood emotional maltreatment was significantly associated with NSSI, and this association was mediated by sleep problems. Moderated mediation analyses revealed that rumination intensified the relation between childhood emotional maltreatment and sleep problems as well as the relation between sleep problems and NSSI.
Findings of this study demonstrate a relationship among childhood emotional maltreatment, sleep problems, rumination and NSSI. Interventions that target sleep problems and rumination may be beneficial for reducing NSSI for at-risk adolescents.
非自杀性自伤（NSSI）是中国青少年中一个非常严重的公共卫生问题，研究发现，儿童期情感虐待是 NSSI 的一个风险因素。
对于儿童期情感虐待与 NSSI 之间的纵向关联及其潜在的中介和调节机制，目前知之甚少。因此，我们假设睡眠问题是否在儿童期情感虐待与 NSSI 之间起中介作用，以及这种间接效应是否受反刍的调节。
共有 1987 名中国青少年（56.1%为男性；年龄 10 至 14 岁，M=12.32，SD=0.53）在三个时间点完成了关于儿童期情感虐待、睡眠问题、反刍和非自杀性自伤（NSSI）的自我报告问卷。
使用结构方程模型检验了一个有调节的中介模型，其中性别、年龄、社会经济地位和基线测量值作为协变量。
儿童期情感虐待与 NSSI 显著相关，且这种相关性由睡眠问题介导。有调节的中介分析表明，反刍加剧了儿童期情感虐待与睡眠问题之间的关系，以及睡眠问题与 NSSI 之间的关系。
本研究的结果表明，儿童期情感虐待、睡眠问题、反刍与 NSSI 之间存在关系。针对睡眠问题和反刍的干预措施可能对减少高危青少年的 NSSI 有益。
