摘要

背景创伤后应激障碍（PTSD）可能受到创伤暴露类型的影响。在评估加拿大退伍军人患创伤后应激障碍的可能性时，这一点很重要，因为以前的文献没有研究过这一点。本研究的目的是：1)根据创伤类型和性别区分，检查16年来PTSD的患病率和条件概率；2)通过最严重的创伤类型探讨这种关系。方法对26例创伤性事件暴露者的PTSD患病率进行性别分析，并采用logistic回归分析创伤类型与PTSD的关系。使用人口归因分数（paf）计算16年随访期间（2002-2018年）和过去一年患创伤后应激障碍的条件概率。同样的分析被用于检查与自我报告的“最坏事件”相关的PTSD的条件概率。结果在16年的随访中，我们发现男性暴露于性创伤后患PTSD的条件可能性更高，而女性暴露于事故相关的创伤后患PTSD的条件可能性更高。对于以最坏事件为条件的创伤后应激障碍的概率，女性与事故或性创伤有关，男性与性和部署有关的创伤显示最高的PAF和最强的关系。结论本研究支持创伤暴露类型对PTSD患病率的影响。重要的是，PTSD的条件概率模式因性别而异。这些发现可以为军队中治疗多重创伤的心理健康提供者提供重要信息。

Conditional probability of posttraumatic stress disorder in the Canadian Armed Forces: A longitudinal study

Background

Posttraumatic stress disorder (PTSD) can be impacted by the type of trauma exposure. This is important to consider when evaluating the likelihood of having PTSD among Canadian veterans, which previous literature has not examined. The aim of this study was to: 1) Examine the prevalence and conditional probability of PTSD over a 16 year period by trauma type, differentiating by sex, and 2) Explore this relationship by worst trauma type.

Methods

We examined the prevalence of PTSD by sex among those with any exposure to 26 traumatic events, and used logistic regressions to examine trauma type and PTSD. The conditional probability of having PTSD over the 16-year follow-up period (2002–2018) and in the past year was calculated using population attributable fractions (PAFs). Identical analyses were used to examine the conditional probability of PTSD related to a self-reported ‘worst event’.

Results

Over the 16-year follow-up, we found that males showed higher conditional likelihood of developing PTSD from exposure to sexual trauma while females showed a higher conditional likelihood of developing PTSD from exposure to an accidentrelated trauma. For the probability of PTSD conditional on the worst event, accidentrelated or sexual trauma in females, and sexual and deployment-related trauma in males showed the highest PAF and strongest relationship.

Conclusion

This research supports differences in PTSD prevalence depending on the type of traumatic exposure. Importantly, different patterns of conditional probability of PTSD emerged by sex. These findings can provide important information for mental health providers within the military treating multiple traumas.

期刊介绍： The Journal of Anxiety Disorders is an interdisciplinary journal that publishes research papers on all aspects of anxiety disorders for individuals of all age groups, including children, adolescents, adults, and the elderly. Manuscripts that focus on disorders previously classified as anxiety disorders such as obsessive-compulsive disorder and posttraumatic stress disorder, as well as the new category of illness anxiety disorder, are also within the scope of the journal. The research areas of focus include traditional, behavioral, cognitive, and biological assessment; diagnosis and classification; psychosocial and psychopharmacological treatment; genetics; epidemiology; and prevention. The journal welcomes theoretical and review articles that significantly contribute to current knowledge in the field. It is abstracted and indexed in various databases such as Elsevier, BIOBASE, PubMed/Medline, PsycINFO, BIOSIS Citation Index, BRS Data, Current Contents - Social & Behavioral Sciences, Pascal Francis, Scopus, and Google Scholar.
