Abstract：
BACKGROUND: Data on self-harm (SH) repetition in non-Western adolescents are limited; this study is to survey the predictors.
METHODS: A total of 5879 adolescents (mean age 16.02 years) in Northern Taiwan were recruited. The participants filled in online questionnaires about their sociodemographic data, suicidality, depressive symptoms, self-esteem, social support, family discord, impulsivity, and alcohol and tobacco use at baseline (T1) and at the 1 year follow-up (T2). We used logistic regression analysis to examine the predictors of SH continuation. Generalized structural equation modeling (GSEM) was then estimated to analyze the treatable variables for both years and to investigate their relationships and mediating effects.
RESULTS: A total of 125 students were identified as being in the SH continuation group; while 470 students were identified as being in the SH stop group. The SH continuation rate was 21%; no significant gender difference was found. Logistic regression analysis showed that the predictors of SH continuation were low school ranking, poor quality of listening from relatives, use of the cutting method for SH, and a suicide plan in the past year at T1, and more depressed mood, use of the cutting method for SH, more suicide ideation and plans at T2. Similar predictors were found by GSEM; self-esteem at T1 and depressed mood at T2 were found to be mediators in the pathways.
CONCLUSIONS: The continuation rate of SH was similar to that reported in Western countries. These predictors should be included in the treatment plan to prevent SH continuation.

摘要：
背景：非西方青少年自我伤害（SH）重复的数据有限；这项研究旨在调查预测因素。
方法：招募了台湾北部的5879名青少年（平均年龄16.02岁）。参与者填写了关于他们的社会人口统计数据的在线问卷，自杀,抑郁症状,自尊,社会支持,家庭不和谐,冲动,在基线（T1）和1年随访（T2）时使用酒精和烟草。我们使用逻辑回归分析来检验SH延续的预测因素。然后估计广义结构方程模型（GSEM），以分析这两年的可处理变量，并研究它们的关系和中介效应。
结果：共有125名学生被确定为SH延续组；而470名学生被确定为SH停止组。SH延续率为21%，无明显性别差异。Logistic回归分析显示,SH延续的预测因子为低学校排名,听亲戚的质量差，使用SH的切割方法，在过去的一年中，T1的自杀计划，以及更沮丧的情绪，使用SH的切割方法，在T2更多的自杀想法和计划。GSEM发现了类似的预测因子；发现T1时的自尊和T2时的抑郁情绪是途径的中介。
结论：SH的延续率与西方国家报道的相似。这些预测因子应包括在治疗计划中以防止SH继续。
