In a prospective study of 1,046 male medical students, those who later committed suicide showed a heightened sensitivity in stressful situations as assessed by the Habits of Nervous Tension Questionnaire (HNT). Survival analyses specified 2 of the 25 HNT items as the strongest suicide predictors: Irritability (relative risk 5.5; 95% confidence interval 1.76-17.17) and Urinary Frequency (3.3; 1.07-10.32). No other risk factors for suicide emerged from family background measures or individual medical school measures. It appears that types of sensitivity reflect psychological characteristics that are long-term precursors of suicide.
在一项针对1046名男性医学生的前瞻性研究中，通过紧张习惯问卷（HNT）评估发现，那些后来自杀的学生在压力情境下表现出更高的敏感性。生存分析确定了HNT的25个项目中的2个是最强的自杀预测指标：易怒（相对风险5.5；95%置信区间1.76 - 17.17）和尿频（3.3；1.07 - 10.32）。从家庭背景指标或医学院个人指标中未发现其他自杀风险因素。似乎敏感性类型反映了作为自杀长期先兆的心理特征。
