自闭症特征与中年和老年自杀倾向：探究心理健康和社会联系的中介作用 Autistic traits and suicidality in midlife and old age: investigating mediating effects of mental health and social connectedness ——《自然 / 心理健康》第4卷，第2期，2026年2月—— <Nature / Mental Health> Volume 4, Issue 2, Feb. 2026 【摘要】中老年自闭症患者的自杀倾向有所增加，但人们对自闭症与中老年自杀倾向之间潜在联系的因素知之甚少。本研究报告了一项横断面观察性研究，纳入了9979名50岁及以上的成年人（76%为女性），他们完成了测量自闭症特征、当前心理健康状况、社会联系和自杀倾向（自杀意念和自杀性自伤）的问卷调查。我们采用路径分析法探讨了自闭症特征与自杀倾向之间的关系，以及当前心理健康状况、社会联系和性别（男性/女性）的中介作用。结果发现，抑郁、焦虑、创伤后应激障碍（PTSD）、孤独感和社会孤立均显著中介了自闭症特征与自杀意念之间的关系，但效应量较小。对于自杀性自伤，男性、抑郁、PTSD和社会孤立被发现是中介因素。我们得出结论，心理健康问题和社会孤立是导致50岁以上具有高度自闭症特征人群自杀率升高的诱因。针对自闭症谱系人群，在其一生中开展有针对性的、个体化的干预措施至关重要。 [Abstract] Suicidality is increased among middle-aged and older autistic adults, but little is known about the underlying factors linking autism with suicidality in midlife and older age. Here we report a cross-sectional observational study of 9,979 adults (76% female) aged 50+ years who completed questionnaires measuring autistic traits, current mental health, social connections and suicidality (suicidal ideation and suicidal self-harm). We use path analysis to explore the relationship between autistic traits and suicidality and the mediating effects of current mental health, social connectedness and male/female sex. Our results find that depression, anxiety, post-traumatic stress disorder (PTSD), loneliness and social isolation all significantly mediate the relationship between autistic traits and suicidal ideation, with small effect sizes. For suicidal self-harm, male sex, depression, PTSD and social isolation were found to be mediators. We conclude that mental health difficulties and social isolation mediate higher rates of suicidality in 50+-year-olds with high autistic traits. Targeted and individually tailored interventions for people on the autism spectrum across the lifespan are important. 论文原文：Eleanor Nuzum, Radvile Medeisyte, Aphrodite Eshetu, et al (2026).
