OBJECTIVE
To document the 6-month prevalence of posttraumatic stress syndrome (PTSS) in the older adult population and the validity of a PTSS Scale in an epidemiologic setting.
METHOD
Data came from the Enquête sur la santé des aînés et l'utilisation des services de santé (ESA Services Study) conducted during 2012-2013 using a probability sample of older adults seeking medical services in primary health clinics.
RESULTS
Results showed that a first-order PTSS measurement model consisting of 3 indicators-the number of lifetime traumatic events, the frequency of reactions and symptoms of distress associated with the traumatic events, and the presence of consequences on the social functioning-was plausible. Reliability of the PTSS was 0.82. According to the PTSS, 11.1% of the older adult patients presented with PTSS, but only 21.7% of them reported an impact of their symptoms on their social functioning. The prevalence of older adults meeting the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for full posttraumatic stress disorder (PTSD) reached 1.8%, and 1.8% of older adults reached criteria for partial PTSD. Our results also showed that women were more at risk to report PTSS than men and that older adults aged 75 years and older were less likely to report these symptoms than those aged between 65 and 74 years.
CONCLUSIONS
PTSS is a common mental health problem among adults aged 65 and older and seeking health services in the general medical sector.
目的
记录老年人创伤后应激障碍（PTSS）的 6 个月患病率，并评估在流行病学环境中使用 PTSS 量表的有效性。
方法
数据来自 2012-2013 年期间进行的老年人健康与医疗服务使用调查（ESA 服务研究），该调查采用了一个概率样本，包括在初级保健诊所寻求医疗服务的老年人。
结果
结果表明，一个由 3 个指标组成的一阶 PTSS 测量模型是合理的，这 3 个指标是：一生中经历创伤性事件的次数、与创伤性事件相关的反应和症状的频率、以及对社会功能的影响。PTSS 的信度为 0.82。根据 PTSS，11.1%的老年患者患有 PTSS，但只有 21.7%的患者报告其症状对其社会功能有影响。符合《精神障碍诊断与统计手册》第四版（DSM-IV）完全创伤后应激障碍（PTSD）标准的老年患者患病率为 1.8%，符合部分 PTSD 标准的老年患者患病率为 1.8%。我们的研究结果还表明，女性比男性更容易报告 PTSS，75 岁及以上的老年人比 65-74 岁的老年人更不容易报告这些症状。
结论
PTSS 是 65 岁及以上成年人在普通医疗领域寻求医疗服务时常见的心理健康问题。
