摘要

目的:轻度创伤性脑损伤(mTBI)后通常会出现主观认知症状,但这些症状往往与客观认知表现无关。这可能是由于传统的认知表现测量方法存在局限性,对急性 mTBI 后认知的细微变化不够敏感。本研究使用基于计算机的、认知负荷不断增加的任务来探索客观认知与主观认知之间的关联,该任务被认为对认知表现的细微差别更为敏感:方法:前瞻性地招募了 mTBI 患者(68 人)和外伤对照组(40 人),并在伤后约 8 周进行了评估。参与者完成了主观症状报告、客观认知表现(包括两项认知负荷不断增加的基于计算机的任务)和心理困扰的测量:结果:在 mTBI 组中,主观和客观认知报告之间没有明显的相关性,无论是双变量相关性(|r| = 0.01-0.20, p > .05)还是控制心理困扰(|r| = 0.00-0.17, p > .05)。在创伤对照组中也观察到了类似的结果,这表明mTBI患者的客观认知和主观认知之间的有限关系可能并不是这一人群所特有的:结论:尽管采用了比传统任务更敏感的认知表现测量方法,但在急性 mTBI 患者中并未观察到客观认知和主观认知之间的显著关系,估计效应大小也很小,甚至可以忽略不计。这进一步证明,在创伤性脑损伤后 8 周的群体水平上,主观认知症状主要反映客观认知以外的因素。

Cognitive Symptoms Are Not Associated with Cognitive Performance in Post-Acute mTBI.

Objective: Subjective cognitive symptoms are commonly reported after mild traumatic brain injury (mTBI) but are often not associated with objective cognitive performance. This may be due to limitations in traditional cognitive performance measures, which may not be sensitive to subtle variations in cognition in post-acute mTBI. This study explored associations between objective and subjective cognition using computer-based tasks of increasing cognitive load, proposed to be more sensitive to subtle differences in performance.

Method: Individuals with mTBI (n = 68) and trauma controls (n = 40) were prospectively recruited and assessed approximately 8 weeks post-injury. Participants completed measures of subjective symptom reporting, objective cognitive performance (including two computer-based tasks of increasing cognitive load), and psychological distress.

Results: There were no significant associations between subjective and objective cognition reporting in the mTBI group, both in bivariate correlations (|r| = 0.01-0.20, p > .05) and when controlling for psychological distress (|r| = 0.00-0.17, p > .05). A similar pattern of results was observed in trauma controls, suggesting that the limited relationships between objective and subjective cognition in mTBI may not be specific to this population.

Conclusions: Despite employing measures of cognitive performance proposed to be more sensitive than traditional tasks, no significant relationships were observed between objective and subjective cognition in post-acute mTBI, and estimated effect sizes were small to negligible. This provides further evidence that at a group level 8 weeks after mTBI subjective cognitive symptoms primarily reflect factors aside from objective cognition.

期刊介绍: The journal publishes original contributions dealing with psychological aspects of the etiology, diagnosis, and treatment of disorders arising out of dysfunction of the central nervous system. Archives of Clinical Neuropsychology will also consider manuscripts involving the established principles of the profession of neuropsychology: (a) delivery and evaluation of services, (b) ethical and legal issues, and (c) approaches to education and training. Preference will be given to empirical reports and key reviews. Brief research reports, case studies, and commentaries on published articles (not exceeding two printed pages) will also be considered. At the discretion of the editor, rebuttals to commentaries may be invited. Occasional papers of a theoretical nature will be considered.
