前瞻性记忆（PM）或“记住记住”已被证明在有轻度创伤性脑损伤（mTBI）历史的退伍军人中减少，特别是在具有高战略要求的任务中，例如在没有外部线索的情况下回忆基于时间的信息。本研究探讨了是否在PM任务期间的时间监测减少在退伍军人与mTBI的历史，并与基于时间的PM performance.MethodVeterans与mTBI的历史（n = 49）和退伍军人没有TBI的历史（n = 16）完成的意图筛选测试（MIST）的记忆作为一种措施，在此期间，他们的时间监测结果调整年龄、教育程度、抑郁和PTSD症状后，负二项回归显示，与对照组相比，mTBI组检查时钟的频率较低（Cohen'sd= 0.84，p = 0.005）。在mTBI组中，在整个MIST任务中不太频繁的时间监测与基于时间的MIST表现较差相关（rs= 0.57，p < 0.001），但与基于事件的MIST无关（rs= 0.04，p = 0.768）.结论与没有mTBI病史的退伍军人相比，有mTBI病史的退伍军人在PM任务期间的监测时间显著减少，这与具有战略要求的PM有关。目前的研究结果表明，mTBI相关的困难与战略方面的PM可能是由于减少时间监测。需要进一步的研究来确定缩短监测时间是否也会导致现实世界中mTBI相关PM困难（例如，药物不依从性）。
ObjectiveProspective memory (PM) or “remembering to remember” has been shown to be reduced in Veterans with histories of mild traumatic brain injury (mTBI), particularly on tasks with high strategic demands such as recalling time-based information in the absence of external cues. This study examined whether time monitoring during a PM task was reduced in Veterans with a history of mTBI and was associated with time-based PM performance.MethodVeterans with a history of mTBI (n = 49) and Veterans without a history of TBI (n = 16) completed the Memory for Intentions Screening Test (MIST) as a measure of PM during which their time monitoring (i.e. number of clock checks) was recorded.ResultsAdjusting for age, education, depression, and PTSD symptoms, negative binomial regression revealed that the mTBI group checked the clock less frequently compared to the control group (Cohen’sd= 0.84,p= 0.005). Within the mTBI group, less frequent time monitoring across the entire MIST task was associated with poorer time-based MIST performance (rs= .57,p< 0.001), but not with event-based MIST (rs= .04,p= 0.768).ConclusionsVeterans with a history of mTBI evidenced significantly reduced time monitoring during a PM task compared to Veterans without a history mTBI, which was associated with strategically-demanding PM. Current findings provide that mTBI-associated difficulties with strategic aspects of PM may be due to reduced time monitoring. Future studies are needed to determine if reduced time monitoring also contributes to mTBI-associated PM difficulties in the real-world (e.g. medication non-adherence).
