The aim of this study was to evaluate clinical, neuropsychological, and functional differences between severe traumatic brain injury (TBI) outpatients with good and/or heightened metacognitive self-awareness (SA) and those with impaired metacognitive SA, assessed by the Patient Competency Rating Scale (PCRS). Fifty-two outpatients were recruited from a neurorehabilitation hospital based on the following inclusion criteria: 1) age > or = 15 years; 2) diagnosis of severe TBI; 3) availability of neuroimaging data; 4) post-traumatic amnesia resolution; 5) provision of informed consent.
A neuropsychological battery was used to evaluate attention, memory and executive functions. SA was assessed by the PCRS, which was administered to patients and close family members. Patients were divided into two groups representing those with and without SA. Patients with poor SA had more problems than those with good SA in some components of the executive system, as indicated by the high percentage of perseverative errors and responses they made on the Wisconsin Card Sorting Test. Moreover, a decrease in metacognitive SA correlated significantly with time to follow commands (TFC). This study suggests the importance of integrating an overall assessment of cognitive functions with a specific evaluation of SA to treat self-awareness and executive functions together during the rehabilitation process.
本研究旨在评估临床、神经心理学和功能差异严重创伤性脑损伤（TBI）门诊病人有良好的和/或提高元认知自我意识（SA）和那些受损的元认知 SA，由患者能力评定量表（PCR）评估。52 例门诊病人从一个神经康复医院的基础上，包括以下标准：1）年龄≥15 岁；2）诊断为严重 TBI；3）神经影像学资料；4）创伤后遗忘解决；5）提供知情同意。
神经心理学电池用于评估注意力、记忆和执行功能。SA 由 PCRS 评估，它被管理到病人和家属。病人分为两组代表 SA 有和没有。有 SA 病人比那些有良好的 SA 有更多的问题在执行系统的一些组件，由高比例的坚持错误和他们对威斯康星卡片分类测验的反应。此外，元认知 SA 明显下降与时间来执行命令（TFC）。本研究表明的重要性，整合认知功能的整体评估与特定的评价 SA 治疗自我意识和执行功能一起在康复过程中。
