We examined the adaptation of the Beck Hopelessness Scale (BHS) as a subjective suicide risk assessment tool in detecting Nigerian patients with schizophrenia who are at a high risk of suicide.
Schizophrenia patients (211) completed the BHS in addition to a sociodemographic questionnaire. They were objectively interviewed with the suicidality module of the Mini International Neuropsychiatric Interview (MINI) as the 'gold standard', against which the criterion validity of the BHS was examined.
The receiver operating characteristics (ROC) curve of the 20-item BHS scale at a total cut-off score of 9 (sensitivity 0.889, specificity 0.916) against the patients' MINI Suicidality Module risk categorisation had an Area Under the Curve (AUC) of 0.96 (95% CI: 0.928-0.987), while, the four-item BHS scale demonstrated a ROC curve with an AUC of 0.92 (95% CI: 0.868-0.966) at a cut-off score of 1 (sensitivity 1.000, specificity 0.832).
The BHS has proven to be valid in terms of its sensitivity and specificity in the identification of the high suicidal risk Nigerian schizophrenia outpatients.
我们研究了贝克绝望量表（BHS）作为一种主观自杀风险评估工具的适应性，以检测尼日利亚患有精神分裂症且自杀风险较高的患者。
211 名精神分裂症患者除了填写一份社会人口学问卷外，还完成了 BHS。他们通过 Mini 国际神经精神访谈（MINI）的自杀模块进行客观访谈，MINI 是“金标准”，用其来检验 BHS 的标准效度。
在总截断分数为 9 分的情况下，20 项 BHS 量表的受试者工作特征（ROC）曲线（敏感度 0.889，特异性 0.916）与患者的 MINI 自杀模块风险分类相比，曲线下面积（AUC）为 0.96（95%CI：0.928-0.987），而四项 BHS 量表的截断分数为 1 分的 ROC 曲线 AUC 为 0.92（95%CI：0.868-0.966），敏感度为 1.000，特异性为 0.832。
BHS 在识别高自杀风险的尼日利亚精神分裂症门诊患者方面具有较高的敏感度和特异性，证明其具有有效性。
