The Interpersonal-Psychological Theory of Suicide (IPTS) has been increasingly studied over the last years, responding to the demand for a valid framework addressing suicidality. Yet, only a few studies have explored the function of personality in the IPTS and none with clinical patients. We aimed to contribute to fill this gap in investigating the relationship between personality as conceptualized by the Five-Factor Model, the IPTS constructs, and a dimensional measure of current suicidal ideation. We conducted correlation, multiple linear regression, and path analyses based on a trait-interpersonal framework in a sample of 201 individuals visiting the psychiatric emergency room of a general hospital with current suicidal ideation. Neuroticism (positively) and openness (negatively) predicted perceived burdensomeness, while neuroticism (positively) and extraversion (negatively) predicted thwarted belongingness. Higher conscientiousness and lower extraversion were both predictors of the acquired capability for suicide. However, none of the models involving path analyses with IPTS variables as mediators of the relationship between personality traits and suicidal ideation was adequately adjusted to the data. Thus, it appears that personality plays a significant albeit modest role in suicidality when considered from an IPTS perspective. As personality is frequently assessed in the clinical routine, health professionals should consider it as complementary to detect individuals at risk of or presenting suicidal ideation.
近年来，人们越来越多地研究人际-心理理论的自杀（IPTS），以满足对有效框架的需求，以解决自杀问题。然而，只有少数研究探讨了人格在 IPTS 中的作用，而且没有针对临床患者的研究。我们旨在通过研究五因素模型、IPTS 结构以及当前自杀意念的维度测量所概念化的人格之间的关系，为填补这一空白做出贡献。我们对 201 名有当前自杀意念的个体进行了相关性、多元线性回归和路径分析，这些个体来自一家综合医院的精神科急诊室。神经质（正相关）和开放性（负相关）预测感知负担，而神经质（正相关）和外向性（负相关）预测归属感受挫。更高的尽责性和更低的外向性都是获得自杀能力的预测因素。然而，没有一个涉及 IPTS 变量作为人格特质和自杀意念之间关系的中介的路径分析模型能够充分适应数据。因此，从 IPTS 的角度来看，人格在自杀倾向中起着重要但适度的作用。由于人格在临床常规中经常被评估，因此健康专业人员应该将其视为补充手段，以发现有自杀意念风险或出现自杀意念的个体。
