摘　　要：目的评估自杀行为问卷-修订版(Suicidal Behaviors Questionnaire-Revised,SBQ-R)在中国大学生中的信效度,并确定筛查大学生临床群体自杀风险的最佳划界分。方法共招募488名大学生,其中第一次采用整群抽样的方法招募366人,填写中文版SBQ-R、心理痛苦量表中文版和生活满意度量表,4周后抽取其中45名被试重测;第二次采用方便取样的方法招募122人,采用访谈加问卷的形式,以简明国际神经精神访谈的自杀模块为金标准划定划界分。结果(1)验证性因子分析结果支持了该问卷的单维性;(2)SBQ-R的Cronbach’sα系数为0.76,分半信度和4周后的重测信度分别为0.79和0.93;(3)SBQ-R得分与心理痛苦结果显著正相关,与生活满意度量显著负相关,表明该量表具有良好的效标关联效度;(4)受试者工作特征(ROC)曲线分析结果表明,划界分为9分时,敏感度和特异度最高,ROC曲线下面积(AUC)为0.916。结论中文版SBQ-R具有良好的信效度,可以作为评估中国大学生群体自杀风险的有效工具,且SBQ-R筛查自杀风险的最佳截断值为9分。Objective To examine the reliability and validity of the Suicidal Behaviors Questionnaire-Revised(SBQ-R)among Chinese undergraduates and to find out cut-off score for screening the risk of suicide in clinical undergraduates.Methods A total of 488 Chinese undergraduates participated in this study.Of them,366 participants were asked to complete the Chinese version of SBQ-R,Psychache Scale,and Satisfaction with Life Scale.And 45 undergraduates were re-tested after four weeks;122 undergraduates were tested by using the Suicidality Module Section of the Mini International Neuropsychiatric Interview and the Chinese version of SBQ-R.Results(1)The results showed that The Chinese version of SBQ-R had one factor with good fit indices.(2)The internal consistency reliability,split-half reliability,and one-month retest reliability of the total questionnaire were 0.76,0.79,and 0.93,respectively.(3)The total score of the SBQ-R in Chinese was positively correlated with psychache but negatively correlated with satisfaction of life,indicating that the scale has good criterion-related validity.(4)Receiver operating characteristics(ROC)curve evaluation suggested that the cut-off score was 9 in terms of identifying the clinical undergraduates at high risk of suicide.Conclusion SBQ-R is a reliable,valid,and practical instrument to measure the risk of suicide among Chinese undergraduates.SBQ-R>9 is the best cut-off value for screening for high suicide risk in China.
