简介：由于共病的发生率较高、多次暴露以及缺乏急性病历，针对与部署相关的创伤性脑损伤 (TBI) 的研究相当复杂。因此，需要一个明确的、匹配的比较组。这项研究比较了最近部署的未受过任何伤害的退伍军人与在部署期间遭受骨科损伤但没有 TBI 病史的退伍军人的部署相关特征、日常功能和认知表现。 方法：参与者包括 45 名已部署且未受伤的人员以及 27 名在部署期间报告至少一次骨科损伤的人员。使用 Mayo-Portland 适应性量表 – 4、社区融合问卷、退伍军人 RAND 36 项目健康调查、简短疼痛量表、Barratt 冲动量表 – 11 和创伤后应激障碍 (PTSD) 平民清单 (PCL-C) 来评估日常功能。使用受控口语联想测试、线索测试、颜色词干扰测试和言语选择性提醒测试来测量认知表现。使用基于等方差的检验对两组进行比较。计算效应大小。结果：不存在组间差异，所有变量的 p 值 >.1，效应大小为小到中等。讨论：与其他没有受伤史的部署人员相比，部署期间发生的骨科损伤不需要后送或住院，对参与者的健康、认知和日常功能没有任何持久影响。这些结果表明这两个组具有可比性，并且可以将它们的数据合并起来创建一个比较组。由于本研究的样本量较小，目前的结果被认为是初步的，还需要进一步的调查。
Introduction: Research addressing deployment-related traumatic brain injury (TBI) is fairly complex due to a high prevalence of comorbid conditions, multiple exposures, and the lack of acute medical records. Therefore, there is a need for a well-defined, matching comparison group. This study compared deployment-related characteristics, everyday functioning, and cognitive performance in recently deployed veterans who had not sustained any injuries with those who had orthopedic injuries during deployment, but who were without a history of TBI.Method: Participants included 45 individuals who had been deployed and who were without injuries and a group of 27 individuals who reported at least one orthopedic injury during deployment. The Mayo–Portland Adaptability Inventory–4, Community Integration Questionnaire, Veterans RAND 36 Item Health Survey, Brief Pain Inventory, Barratt Impulsiveness Scale–11, and posttraumatic stress disorder (PTSD) Checklist–Civilian (PCL-C) were used to assess daily functioning. Cognitive performance was measured using the Controlled Oral Word Association Test, Trail Making Test, Color–Word Interference Test, and Verbal Selective Reminding Test. The two groups were compared usingttests based on equal variances. The effect size was calculated.Results: There were no between-group differences, with all variables havingp-values >.1 and small to medium effect sizes.Discussion: Orthopedic injuries sustained during deployment that did not require evacuation or hospitalization did not have any lasting effect on participants’ health, cognition, and daily functioning relative to other deployed individuals with no history of injury. These results indicate the two groups are comparable and that their data could be potentially combined to create a single comparison group. Due to the small sample available for this study, the current results are considered preliminary, and further investigation is needed.
