背景：自杀是发达国家大学生死亡率的主要原因。目前还没有可靠和有效的自我报告自杀评估量表，具有足够的敏感性和特异性，用于识别尼日利亚大学生未来有自杀行为风险。目的：本研究旨在探讨自杀行为量表修订版（SBQ-R）的心理测量学特征，以作为华南地区大学生自杀风险评估的筛选工具。方法：这是一个横断面描述性研究，涉及536名尼日利亚本科学生。学生们完成了SBQ-R，除了社会人口统计学和学术相关的问卷，医院焦虑和抑郁量表（HADS），和12项一般健康问卷（GHQ 12）。自杀危险类别的学生进行了采访，他们与自杀模块部分的迷你国际神经精神Interview（MINI）的项目。结果：Cronbach的α SBQ-R项目为0.80。结构效度支持通过显着的正相关与HADS焦虑和抑郁分量表，和GHQ-12。受试者工作特征（ROC）曲线评价表明，具有最佳灵敏度的最佳截断总分（0.882），特异性（0.875）和最高精度（0.879）在识别自杀高危学生方面为8（曲线下面积= 0.928; 95%置信区间= 0.890-0.966;标准误= 0.019）。结论：SBQ-R的使用可能是预防尼日利亚大学生自杀企图的重要和至关重要的一步。(C)2017爱思唯尔B.

Background: Suicide is a major contribution to mortality among university students in developed countries. There is no reliable and validated self-report suicide assessment scale with adequate sensitivity and specificity for the identification of Nigerian university students who are at risk of future suicidal behaviors.Objective: The objective of this study was to examine the psychometric characteristics of the 4 item Suicidal Behaviors Questionnaire-Revised (SBQ-R) as a screening tool for suicide risk assessment among university undergraduate students in South-western Nigeria.Method: This is a cross-sectional descriptive study involving 536 undergraduate Nigerian students. The students completed the SBQ-R, in addition to a sociodemographic and academic related questionnaire, the Hospital Anxiety and Depression Scale (HADS), and the 12 item General Health Questionnaire (GHQ12). Suicidal risk categories among the students were determined by interviewing them with the items of the suicidality module section of the Mini International Neuropsychiatric Interview (MINI).Results: Cronbach's alpha for the SBQ-R items was 0.80. Construct validity was supported through significant positive correlations with the HADS-Anxiety and Depression subscales, and the GHQ-12. Receiver Operating Characteristics (ROC) curve evaluation suggests that the best cut-off total score with the optimal sensitivity (0.882), specificity (0.875) and highest accuracy (0.879) was 8 in terms of identifying the students at high risk of suicide (Area Under the Curve = 0.928; 95% Confidence Interval = 0.890-0.966; Standard Error = 0.019).Conclusions: The use of the SBQ-R may be an important and vital step in the prevention of suicidal attempts among Nigerian university students.
