目的：确定JFK昏迷恢复量表修订版（CRS-R）的测量特性和诊断效用。设计：分析评定者间和重测信度、内部一致性、同时效度和诊断准确性。设置：急性住院脑损伤康复医院。参与者：80例严重获得性脑损伤患者的便利样本，这些患者入院接受昏迷干预计划，诊断为主要结果测量：CRS-R、JFK昏迷恢复量表（CRS）和残疾评定量表（DRS）。结果：CRS-R总分的评定者间和重测信度较高。子量表分析显示，中度至高度评价者和重测协议，但系统的差异，评分的视觉和ormalware/verbal子量表。CRS-R总分与CRS和DRS总分显著相关，表明可接受的同时效度。CRS-R能够区分10例MCS中的患者，否则他们被错误分类为VS by the DRS.Conclusions：CRS-R可以可靠地由训练有素的检查员和重复测量产生稳定的估计患者的状态。CRS-R子量表评分在评定者和评定者之间表现出良好的一致性，但应谨慎使用，因为某些评分在当前研究中代表性不足。CRS-R似乎能够区分MCS患者和VS患者。
Objective: To determine the measurement properties and diagnostic utility of the JFK Coma Recovery Scale-Revised (CRS-R).Design: Analysis of interrater and test-retest reliability, internal consistency, concurrent validity, and diagnostic accuracy.Setting: Acute inpatient brain injury rehabilitation hospital.Participants: Convenience sample of 80 patients with severe acquired brain injury admitted to an inpatient Coma Intervention Program with a diagnosis of either vegetative state (VS) or minimally conscious state (MCS).Interventions: Not applicable.Main Outcome Measures: The CRS-R, the JFK Coma Recovery Scale (CRS), and the Disability Rating Scale (DRS).Results: Interrater and test-retest reliability were high for CRS-R total scores. Subscale analysis showed moderate to high interrater and test-retest agreement although systematic differences in scoring were noted on the visual and oromotor/verbal subscales. CRS-R total scores correlated significantly with total scores on the CRS and DRS indicating acceptable concurrent validity. The CRS-R was able to distinguish 10 patients in an MCS who were otherwise misclassified as in a VS by the DRS.Conclusions: The CRS-R can be administered reliably by trained examiners and repeated measurements yield stable estimates of patient status. CRS-R subscale scores demonstrated good agreement across raters and ratings but should be used cautiously because some scores were underrepresented in the current study. The CRS-R appears capable of differentiating patients in an MCS from those in a VS.
