OBJECTIVE Impaired self-awareness (ISA) of altered functional capacities is a common sequelae of severe acquired brain injury that can severely hamper neuro-rehabilitation in this clinical population. ISA is frequently associated with anosodiaphoria and/or apathy. Although several scales are available to measure apathy, no tools have been published to specifically assess anosodiaphoria after acquired brain injury. In this paper, we reported an initial effort to develop an anosodiaphoria subscale in a commonly used measure of ISA, that is, the Patient Competency Rating scale-neurorehabilitation form (PCRS-NR). METHOD A sample of 46 participants with severe acquired brain injury completed a functional, ISA, apathy, and anosodiaphoria assessment. One informal caregiver of each patient participated in the study. Thus, we were able to obtain external data on his/her level of functional competencies, and self-awareness, which allowed separating patients with low self-awareness (LSA) from those with high self-awareness (HSA). Finally, the patients were compared with 44 healthy age-gender-years of formal education matched control participants (HCs). RESULTS Compared to both patients with HSA and HCs, patients with LSA demonstrated greater anosodiapvhoria and lower levels of functioning than both HSA patients and HCs. A stronger relationship emerged between ISA and anosodiaphoria rather than with apathy. CONCLUSIONS These initial findings provide support that PCRS scale can be adapted to measure anosodiaphoria as well as ISA. The findings reveal a stronger correlation between this measure of anosodiaphoria and ISA compared with the correlation of apathy to ISA. The present method for measuring anosodiaphoria takes into account the actual levels of patients' functioning.

修改患者能力评定量表以测量严重后天性脑损伤后厌食症：初步发现。

目标 功能能力改变的自我意识受损 (ISA) 是严重获得性脑损伤的常见后遗症，可严重阻碍该临床人群的神经康复。ISA 通常与厌食症和/或冷漠有关。尽管有多种量表可用于衡量冷漠，但尚未发布专门评估后天性脑损伤后厌食症的工具。在本文中，我们报告了一项初步努力，即在 ISA 的一种常用测量方法中开发一个 anosodiaphoria 子量表，即患者能力评定量表-神经康复表 (PCRS-NR)。方法 46 名患有严重后天性脑损伤的参与者样本完成了功能、ISA、冷漠和厌食症评估。每位患者的一位非正式护理人员参与了这项研究。因此，我们能够获得关于他/她的功能能力水平和自我意识水平的外部数据，这可以将自我意识低 (LSA) 的患者与自我意识高 (HSA) 的患者区分开来。最后，将患者与 44 名健康的年龄-性别-年正规教育相匹配的对照参与者 (HC) 进行比较。结果 与 HSA 和 HC 患者相比，LSA 患者表现出比 HSA 患者和 HC 患者更大的厌食症和更低的功能水平。ISA 和厌食症之间出现了更强的关系，而不是冷漠。结论 这些初步发现支持 PCRS 量表可以适用于测量厌氧尿酸和 ISA。研究结果表明，与冷漠与 ISA 的相关性相比，这种厌食症与 ISA 之间的相关性更强。
