:The most widely used proxies of cognitive complaint after mTBI are post-concussion syndrome (PCS) symptom checklists, which do not have a clear relationship with cognition. This study investigated whether an mTBI-specific cognitive complaint measure would have clearer associations with objective cognition than a widely used PCS symptom checklist.:An observational design was used. A sample of 109 participants (52 mTBI and 57 healthy controls) completed a PCS symptom checklist, a cognitive complaint measure, and measures of information processing speed, attention, memory, executive function, depression and anxiety.:In the healthy control group, cognitive complaint was significantly associated with objective cognitive performance and was not associated with psychological status. In contrast, PCS endorsement was unrelated to objective cognition but was associated with psychological status. For the mTBI group, neither PCS endorsement nor cognitive complaint was associated with cognitive performance, but both measures were associated with psychological status.:This study indicates that neither cognitive nor PCS symptom measures are reliable indicators of underlying cognitive function in the post-acute period after mTBI. Further, suffering an mTBI may affect the linear relationship that exists between cognitive symptom endorsement and cognitive function in healthy adults.
:最常用于 mTBI 后认知主诉的替代指标是脑震荡后综合征（PCS）症状检查表，但它们与认知没有明确的关系。本研究旨在调查一种特定于 mTBI 的认知主诉测量方法与广泛使用的 PCS 症状检查表相比，是否与客观认知有更清晰的关联。
:采用观察性设计。109 名参与者（52 名 mTBI 和 57 名健康对照组）完成了 PCS 症状检查表、认知主诉测量、信息处理速度、注意力、记忆、执行功能、抑郁和焦虑的测量。
:在健康对照组中，认知主诉与客观认知表现显著相关，与心理状态无关。相比之下，PCS 认可与客观认知无关，但与心理状态有关。对于 mTBI 组，PCS 认可和认知主诉都与认知表现无关，但这两种措施都与心理状态有关。
:本研究表明，在 mTBI 后急性后期，认知主诉和 PCS 症状测量都不是潜在认知功能的可靠指标。此外，mTBI 可能会影响健康成年人中认知主诉与认知功能之间存在的线性关系。
