Research has demonstrated that traumatic experiences have significant links to suicidal ideation (SI), particularly among older adults. The present study examined SI among older adults with a history of war trauma and the role of perceptions relating to one's age (subjective age) in predicting SI.
Drawing from a larger longitudinal study, we analyzed data based on interviews with 125 ex-prisoners of war (ex-POWS) from Israel's 1973 Yom Kippur War and a control group of 101 veterans from the same war who did not fall captive (mean age at most recent measurement was 65.05, = 5.29). Participants were interviewed in 2008 (T1) and again in 2015 (T2).
Findings revealed significantly higher levels of SI among ex-POWs than evident among controls and significantly higher levels of SI and subjective age among ex-POWs with PTSD. Furthermore, a sequential mediation analysis indicated that among ex-POWs, the path from T1 PTSD symptoms to subsequent SI was mediated by subjective age at T1, and subjective age at T2, after controlling for age, self-rated health, and SI at T1.
A subset of ex-POWs are exposed to continuous suicidal risk throughout their later life, more than 40 years after the war. Furthermore, an older subjective age mediated these associations, independent of the levels of T1 SI, actual age, and self-rated health. These findings suggest debilitating long-term effects of trauma for SI in later life and their connections to advanced psychological aging.

研究表明，创伤经历与自杀意念（SI）有显著关联，尤其是在老年人中。本研究调查了有战争创伤史的老年人中的 SI 情况，以及与年龄相关的认知（主观年龄）在预测 SI 中的作用。
本研究基于对 125 名来自以色列 1973 年赎罪日战争的前战俘（ex-POWS）和 101 名来自同一战争但未被俘的退伍军人（ex-POWS）的访谈，分析了来自一项更大的纵向研究的数据（ex-POWS）（ex-POWS）（ex-POWS）。ex-POWS 的平均年龄为 65.05 岁，控制组退伍军人的平均年龄为 65.05 岁。参与者于 2008 年（T1）和 2015 年（T2）接受访谈。
研究结果显示，与对照组相比，前战俘的 SI 水平明显更高，患有 PTSD 的前战俘的 SI 和主观年龄水平明显更高。此外，一项顺序中介分析表明，在前战俘中，从 T1 PTSD 症状到随后的 SI 的路径是由 T1 时的主观年龄和 T2 时的主观年龄介导的，在控制了年龄、自我评估健康状况和 T1 时的 SI 之后。
在战争结束 40 多年后，一部分前战俘在他们的晚年一直面临持续的自杀风险。此外，主观年龄较大中介了这些关联，独立于 T1 SI、实际年龄和自我评估健康状况。这些发现表明，创伤对晚年 SI 存在长期的衰弱影响，以及它们与高级心理衰老的联系。（PsycInfo 数据库记录（c）2021 APA，保留所有权利）。
