Abstract：
Suicide is the leading cause of death for adolescents in several parts of Asia, including Singapore. This study examines the relationship between temperament and youth suicide attempts in a sample of multi-ethnic Singaporean adolescents.
A case-control design compared 60 adolescents (Mage = 16.40, SDage = 2.00) with a recent suicide attempt (i.e., past 6 months) with 58 adolescents (Mage = 16.00, SDage = 1.68) without any history of suicide attempts. Presence of suicide attempts was established using the semi-structured interviewer-administered Columbia Suicide Severity Rating Scale. Participants also completed self-report measures on temperament traits, psychiatric diagnoses, stressful life events, and perceived parental rejection in an interview-based format.
Psychiatric comorbidity, recent stressful life events, perceived parental rejection, and all five \"difficult temperament\" traits, were significantly overrepresented among adolescent cases relative to healthy controls. Adjusted logistic regression models revealed significant associations between suicide attempt, MDD comorbidity (OR: 10.7, 95% Cl: (2.24-51.39)), \"negative mood\" trait (OR: 1.12-1.18, 95% Cl: (1.00-1.27)), and the interaction term of \"positive mood\" and \"high adaptability\" traits (OR: 0.943 - 0.955, 95% Cl: (0.900 - 0.986)). Specifically, \"positive mood\" predicted lower likelihood of a suicide attempt when \"adaptability\" was high (OR: 0.335 - 0.342, 95% Cl: (0.186 - 0.500)) but not low (OR: 0.968 - 0.993, 95% Cl: (0.797 - 1.31)).
Temperament screening may be important to identify adolescents at higher or lower risk of suicide at an early stage. More longitudinal and neurobiological research converging on these temperament findings will be helpful in ascertaining temperament screening as an effective suicide prevention methodology for adolescents.

摘要：
背景：自杀是亚洲几个地区青少年死亡的主要原因，包括新加坡。本研究调查了新加坡多种族青少年样本中气质与青少年自杀企图之间的关系。
方法：病例对照设计比较了60名青少年（Mage=16.40，SDage=2.00）和最近的自杀未遂（即过去6个月），有58名青少年（Mage=16.00，SDage=1.68），没有任何自杀未遂史。自杀企图的存在是使用半结构化的采访者管理的哥伦比亚自杀严重程度等级量表来确定的。参与者还完成了关于气质特征的自我报告测量，精神病诊断,紧张的生活事件，以及以面试为基础的形式感知到的父母拒绝。
结果：精神病合并症，最近有压力的生活事件，感知到父母的拒绝，和所有五个“困难的气质”特征，与健康对照组相比，青少年病例中的比例明显过高。调整后的逻辑回归模型显示，自杀未遂之间存在显着关联，MDD合并症（OR：10.7，95％Cl：（2.24-51.39）），“负面情绪”特征(OR:1.12-1.18，95%Cl:(1.00-1.27))，以及“积极情绪”和“高适应性”特征的相互作用项（OR：0.943-0.955，95％Cl：（0.900-0.986））。具体来说,当“适应性”较高（OR：0.335-0.342，95％Cl：（0.186-0.500））但不低（OR：0.968-0.993，95％Cl：（0.797-1.31））时，“积极情绪”预测自杀企图的可能性较低。
结论：气质筛查对于早期发现自杀风险较高或较低的青少年可能很重要。结合这些气质发现的更多纵向和神经生物学研究将有助于确定气质筛查是青少年有效的自杀预防方法。
