Globally, suicide is the most important cause of mortality among adolescents and young adults. The factor that correlates most significantly with suicide is hopelessness.
The aim is to explore the psychometric adaptation of the Beck Hopelessness Scale (BHS) as a suicide risk evaluation tool among Nigerian university students.
A total of 554 Nigerian students completed the BHS and the Depression Anxiety Stress Scale (DASS). Suicide risk level among them was determined by interviewing them with the Mini International Neuropsychiatric Interview Suicidality module.
Cronbach's alpha for the 16-item BHS was 0.87. It exhibited satisfactory concurrent validity with the Mini International Neuropsychiatric Interview (MINI) Suicidality module and the subscales of the DASS among the students. The 2-factor model of the BHS-16 exhibited satisfactory indices of fitness (goodness of fit index = 0.930; parsimonious goodness of fit index = 0.601; comparative fit index = 0.934; incremental fit index = 0.936; Tucker-Lewis index = 0.910; root mean square error of approximation = 0.059; χ/ df = 1.9). Receiver operating characteristics curve indicated that the best cutoff score for those categorized as high suicide risk was 7 (sensitivity 0.700, specificity 0.908, AUC = 0.897).
The BHS has satisfactory psychometric properties as a suicide risk screening tool among Nigerian university students.
在全球范围内，自杀是青少年和年轻人最重要的死亡原因。与自杀最显著相关的因素是绝望。
旨在探索贝克绝望量表（BHS）作为尼日利亚大学生自杀风险评估工具的心理测量学适应性。
共有 554 名尼日利亚学生完成了 BHS 和抑郁焦虑压力量表（DASS）。通过使用 Mini 国际神经精神病学访谈自杀模块对他们进行访谈，确定了他们的自杀风险水平。
BHS 的 16 项 Cronbach's alpha 为 0.87。它与学生的 Mini 国际神经精神病学访谈（MINI）自杀模块和 DASS 的子量表具有良好的同时效度。BHS-16 的 2 因素模型表现出良好的拟合指数（拟合优度指数=0.930；简约拟合优度指数=0.601；比较拟合优度指数=0.934；增量拟合优度指数=0.936；塔克-刘易斯指数=0.910；均方根误差逼近=0.059；χ/df=1.9）。受试者工作特征曲线表明，将那些归类为高自杀风险的最佳截断值为 7（灵敏度 0.700，特异性 0.908，AUC=0.897）。
BHS 作为尼日利亚大学生自杀风险筛查工具具有良好的心理测量学特性。
