Estimates of the prevalence of mild traumatic brain injury (mTBI) among military personnel and combat veterans rely almost exclusively on retrospective self-reports; however, reliability of these reports has received little attention.
To examine the consistency of reporting of mTBI over time and identify factors associated with inconsistent reporting.
A longitudinal cohort of 948 US National Guard Soldiers deployed to Iraq completed self-report questionnaire screening for mTBI and psychological symptoms while in-theatre 1 month before returning home (time 1, T1) and 1 year later (time 2, T2).
Most respondents (n = 811, 85.5%) were consistent in their reporting of mTBI across time. Among those who were inconsistent in their reports (n = 137, 14.5%), the majority denied mTBI at T1 and affirmed mTBI at T2 (n = 123, 89.8%). Respondents rarely endorsed mTBI in-theatre and later denied mTBI (n = 14, 10.2% of those with inconsistent reports). Post-deployment post-traumatic stress symptoms and non-specific physical complaints were significantly associated with inconsistent report of mTBI.
Military service members' self-reports of mTBI are generally consistent over time; however, inconsistency in retrospective self-reporting of mTBI status is associated with current post-traumatic stress symptoms and non-specific physical health complaints.
对军事人员和作战老兵中轻度创伤性脑损伤 (mTBI) 的患病率的估计几乎完全依赖于回顾性自我报告；然而，这些报告的可靠性却很少受到关注。
检验 mTBI 报告随时间的一致性，并确定与不一致报告相关的因素。
一个由 948 名美国国民警卫队士兵组成的纵向队列，在返回国内前 1 个月（时间 1，T1）和 1 年后（时间 2，T2）在伊拉克部署时，完成了 mTBI 和心理症状的自我报告问卷筛查。
大多数受访者（n=811，85.5%）在报告 mTBI 时具有时间一致性。在那些报告不一致的人中（n=137，14.5%），大多数人在 T1 时否认 mTBI，而在 T2 时肯定 mTBI（n=123，89.8%）。受访者很少在战区报告 mTBI，然后否认 mTBI（n=14，占报告不一致者的 10.2%）。部署后创伤后应激症状和非特异性身体投诉与 mTBI 报告不一致显著相关。
军人自我报告的 mTBI 通常随时间保持一致；然而，mTBI 状态的回顾性自我报告不一致与当前创伤后应激症状和非特异性身体健康投诉有关。
