有证据表明，LLD 的人格特质与自杀意念之间存在横向关联。然而，目前还不清楚人格如何随着时间的推移影响LLD的自杀意念，或者这种关联是否会受到社会心理和生物学个体差异的调节。本研究有三个目的：1）检查人格特质是否会随着时间的推移增加LLD的自杀意念，2）了解这种关系是否受到主观社会支持的影响，3）确定社会支持、人格和自杀意念之间的潜在关系对于男性和女性是否有所不同。参与者参加了杜克大学老年人抑郁症神经认知结果 (NCODE)，这是一项针对 LLD 不良疾病过程预测因素的纵向调查。患者最初于 1994 年 12 月至 2000 年 6 月期间参加 NCODE 研究，并平均随访六年。 NCODE 在自然主义治疗环境中运作。 112 名 60 岁及以上的参与者目前被诊断患有重度抑郁症。抑郁症、自杀意念和社会支持的年度评估（用杜克社会支持指数衡量）。参与者还完成了 NEO 人格量表修订版 (NEO-PI-R)，提供五个主要人格维度（神经质、外向性、开放性、尽责性、宜人性）的测量。单变量逻辑广义线性混合模型（GLMM）分析显示，基线时较高水平的抑郁、较少的主观社会支持、较高的神经质和较低的外向性与随着时间的推移自杀意念可能性的增加显着相关。虽然这些维度与自杀意念之间的关系在多变量分析中不再显着，但社会支持对自杀意念与某些神经质和外向性人格方面之间的关联具有显着的调节作用。对于具有高（但不是低）冲动性和低（但不是高）社交性和积极情绪的 LLD 患者，主观社会支持的减少与自杀意念的可能性增加相关。在所有模型中，社会支持在降低未来自杀意念的可能性方面对女性有利，但对男性不利。社会支持的变化可能会导致具有某些人格特征的老年抑郁症患者产生自杀意念。无论人格特征如何，社会支持的变化对女性的自杀意念有显着影响，但对男性则没有影响。即使控制了抑郁症的严重程度、年龄和自杀未遂史，这些关系也很明显。
Evidence suggests a cross-sectional association between personality traits and suicidal ideation in LLD. Yet, it’s unclear how personality may influence suicidal ideation over time in LLD, or whether such an association would be moderated by psychosocial and biological individual differences. The present study had three aims: 1) to examine whether personality traits increase suicidal ideation in LLD over time, 2) to understand whether this relationship is influenced by subjective social support, and 3) to determine whether the potential relationship between social support, personality, and suicidal ideation is different for men and women. Participants were enrolled in the Duke University Neurocognitive Outcomes of Depression in the Elderly (NCODE), a longitudinal investigation of the predictors of poor illness course in LLD. Patients were initially enrolled in the NCODE study between December 1994 and June 2000 and were followed for an average of six years. NCODE operates in a naturalistic treatment milieu. 112 participants aged 60 and older with a current diagnosis of major depressive disorder. Annual assessments of depression, suicidal ideation, and social support (measured with the Duke Social Support Index). Participants also completed the NEO Personality Inventory-Revised (NEO-PI-R) providing measures of the five major personality dimensions (neuroticism, extraversion, openness, conscientiousness, agreeableness). Univariate logistic generalized linear mixed modeling (GLMM) analyses revealed that higher levels of depression at baseline, less subjective social support, higher neuroticism, and lower extraversion were significantly associated with an increased likelihood of suicidal ideation over time. While the relationship between these dimensions and suicidal ideation were no longer significant in multivariate analyses, there was a significant moderating effect of social support on the association between suicidal ideation and certain neuroticism and extraversion personality facets. Decreased subjective social support was associated with an increased likelihood of suicidal ideation in LLD patients with high (but not low) impulsiveness and low (but not high) gregariousness and positive emotions. Across all models, social support was beneficial to women, but not men, in decreasing the likelihood of future suicidal ideation. Changes in social support may contribute to suicidal ideation in older depressed adults with certain personality traits. Irrespective of personality traits, changes in social support had a significant effect on the suicidal ideation of women but not men. These relationships were apparent even when controlling for depression severity, age, and history of suicide attempt.
