摘要
目的:虚拟自杀范式是一种用于实验室内研究自杀原因的转化方法,本研究旨在探究该方法在中国文化背景下的适用性.方法:选取190名在校大学生作为样本,利用虚拟自杀范式进行实验,并使用自杀意念量表(SI0SS)、人际需求问卷(INQ)、简式Barratt冲动性量表(BBIS)、风险领域特异性量表(DOSPERT)、积极消极情绪量表(PANAS)、贝克自杀意念量表(BSI)、获得性自杀能力—无畏死亡量表(FAD)、简明国际神经精神访谈(MINI)—自杀分量表以及自杀可能性量表(SPS)对虚拟自杀范式的安全性和生态效度进行评估.结果:安全性方面:虚拟自杀场景与对照场景暴露后自杀意念、自杀能力及自杀风险水平组间差异不显著(P＞0.05).生态效度方面:(1)虚拟自杀场景的真实感和自杀相关性评分显著大于零(P＜0.001),且唤起了比对照场景更高的消极情绪(P＜0.001);(2)虚拟自杀选择率为8.33％;(3)虚拟自杀的选择受到自杀意念(OR=9.875)、归属受挫(OR=1.102)、累赘感知(OR=1.154)、冲动性(OR=1.228)和风险倾向(OR=1.043)影响.结论:虚拟自杀范式在安全性和生态效度方面表现出良好的特质,可用于研究国内大学生群体的自杀问题.
Abstract
Objective:The virtual suicide paradigm is a translational method used in laboratory to study the causes of suicide.This study aims to explore the applicability of this method within the Chinese cultural context.Methods:A sample of 190 college students was selected to conduct an experiment using the virtual suicide paradigm.Several scales and ques-tionnaires were used to assessed the safety of the virtual suicide paradigm and the ecological validity of virtual suicidal be-havior,including the Suicidal Ideation Scale(SIOSS),Interpersonal Needs Questionnaire(INQ),Brief Barratt Impulsivity Scale(BBIS),Domain Specificity of Risk Scale(DOSPERT),Positive and Negative Emotions Scale(PANAS),Beck Suicidal Ideation Inventory(BSI),Acquired Suicidal Competence-Fearlessness of Dying Scale(FAD),the Brief International Neuro-psychiatric Interview(MINI)-Suicide subscale,and the Suicide Possibility Scale(SPS).Results:Safety aspects:There was no significant difference between groups in suicidal ideation,suicidal ability and suicide risk levels after exposure to virtual suicide scenes and control scenes(P＞0.05).Ecological validity aspects:(1)The realism and suicide relevance scores of virtu-al suicide scenes were significantly greater than 0(P＜0.001),and they evoked higher negative emotions than control scenes(P＜0.00l);(2)The selection rate of virtual suicide behavior was 8.33％;(3)The choice of virtual suicide was affected by sui-cidal ideation(OR=9.875),thwarted belongingness(OR=1.102),perceived burdensomeness(OR=1.154),impulsivity(OR=1.228),and risk taking(OR=1.043).Conclusion:The virtual suicide paradigm has demonstrated favorable attributes in terms of safety and ecological validity,making it suitable for studying the issue of suicide among domestic college students.
