This study examined associations between diverse types of personality disorder (PD) features, personality traits, suicidal ideation, and protective factors against suicide among community-dwelling older adults.
Participants (N = 109, M age = 71.4 years, 61% female) completed the Coolidge Axis II Inventory, NEO Five-Factor Inventory, Geriatric Suicide Ideation Scale, and Reasons for Living Inventory.
PD features had positive correlations with suicidal ideation and mixed relationships with aspects of reasons for living. Personality traits had negative correlations with suicidal ideation, with the exception of neuroticism, which had a positive relationship, and were mostly unrelated to reasons for living. In regression analyses, borderline and histrionic were the only PD features that contributed significant variance in suicidal ideation, whereas neuroticism was the only personality trait that contributed significant variance in suicidal ideation. No individual PD features or personality traits contributed significant variance in reasons for living.
The findings highlight the complexity of risk and protective factors for suicide and suggest that a thorough assessment of suicidal potential among older adults should include attention to their underlying personality traits.
本研究考察了社区居住的老年人群体中不同类型的人格障碍（PD）特征、人格特质、自杀意念以及自杀保护因素之间的关联。
参与者（N=109，平均年龄 71.4 岁，61%为女性）完成了科利奇轴 II 清单、NEO 五因素清单、老年自杀意念量表和生存理由清单。
PD 特征与自杀意念呈正相关，与生存理由的某些方面呈混合关系。人格特质与自杀意念呈负相关，除了神经质呈正相关外，与生存理由大多无关。在回归分析中，边缘型和表演型是唯一对自杀意念有显著差异贡献的 PD 特征，而神经质是唯一对自杀意念有显著差异贡献的人格特质。没有单个 PD 特征或人格特质对生存理由有显著差异贡献。
这些发现强调了自杀风险和保护因素的复杂性，并表明对老年人自杀潜力的全面评估应包括对其潜在人格特质的关注。
