ResumoPrimary objective: The aim of the present study was to explore the concurrent validity, inter-rater agreement and diagnostic sensitivity of a French adaptation of the Coma Recovery Scale–Revised (CRS-R) as compared to other coma scales such as the Glasgow Coma Scale (GCS), the Full Outline of UnResponsiveness scale (FOUR) and the Wessex Head Injury Matrix (WHIM).Research design: Multi-centric prospective study.Method and procedures: To test concurrent validity and diagnostic sensitivity, the four behavioural scales were administered in a randomized order in 77 vegetative and minimally conscious patients. Twenty-four clinicians with different professional backgrounds, levels of expertise and CRS-R experience were recruited to assess inter-rater agreement.Main outcomes and results: Good concurrent validity was obtained between the CRS-R and the three other standardized behavioural scales. Inter-rater reliability for the CRS-R total score and sub-scores was good, indicating that the scale yields reproducible findings across examiners and does not appear to be systematically biased by profession, level of expertise or CRS-R experience. Finally, the CRS-R demonstrated a significantly higher sensitivity to detect MCS patients, as compared to the GCS, the FOUR and the WHIM.Conclusion: The results show that the French version of the CRS-R is a valid and sensitive scale which can be used in severely brain damaged patients by all members of the medical staff.
