摘　　要：探讨神经质人格和负性生活事件的跨层相互作用对自杀意念的影响。方法:采用自杀意念问卷、青少年生活事件问卷和大五人格量表—神经质分量表等自评量表对618名高中生进行评估,每三个月追踪1次,共追踪7次,历时21个月,用多层线性模型分析数据。结果:在控制了第一次自杀意念和性别的影响后,负性生活事件的主效应(β=.08,F(1,2963)=37.93,p<.001)、负性生活事件与神经质人格的相互作用(β=.03,F(1,2963)=4.35,p<.001)显著,而神经质人格的主效应不显著(β=.59,F(1,557)=3.05,p>.05)。结论:神经质人格和负性生活事件的跨层交互作用可以预测自杀意念的变化,支持素质一应激模型。To examine whether neuroticism moderates the relationship between negative life events and suicidal ideation, we adopted a stratified one-stage cluster sampling to yield a representative sample of public high school students, During the initial assessment, 618 high school students （302 boys, 316 girls） completed the following 3 scales to assess negative life events, neuroticism and suicidal ideation： （1） adolescent life events quetionnaire-revised （ALEQ-R）, （2） NEO five-factor inventory-neuroticism suhscale （NEO-FFI- N）, （3） Suicidal Ideation Questionnaire （SIQ）. Researchers returned to the schools to meet with students every three months for the subsequent 21 months （i.e. , 3months, 6 months, 9 months, 12 months, 15 months,. 18 months and 21 months）. At each of these follow-up assessments, the students completed each of the following questionnaires： （1） SIQ, （2） ALEQ-R. Data were analyzed with hierarchical linear modeling analyses. Our dependent variable was within-subject fluctuations in SIQ scores during the follow-up interval. Our primary predictors of SIQ were fluctuations in ALEQ-R scores during the follow-up interval （STRESS）, and NEO fivefactor inventory-neuroticism subscale （NEO-FFI-N）. As NEO-FFI-N is a between-subject variable, NEO-FFI-N scores were standardized prior to analyses. As STRESS is a within-subject predictor, ALEQ-R scores were centered on each participant＇s mean prior to analyses so that STRESS reflected upwards or downwards fluctuations in an adolescent＇s level of stress compared with his/her mean level of stress. The results： Hierarchical linear modeling analyses indicated that after controlling the effects of initial levels of suicidal ideation and gender on suicidal ideation, a non-significant main effect of neuroticism rose （β = . 59, F（1, 557） = 3.05, p 〉 . 05）, while a significant main effect of negative life events （β = . 08, F （1, 2963） = 37.93, p 〈 001 ） appeared. Additionally, a significant two-way,
