Classification
Supplemental for Traumatic Brain Injury (TBI).
Short Description of Instrument
The JFK Coma Recovery Scale-Revised (CRS-R) consists of twenty-three items comprising six hierarchically-arranged subscales addressing auditory, visual, motor, oromotor/verbal, communication and arousal functions. The lowest item on each subscale represents reflexive activity while the highest items represent cognitively-mediated behaviors.
Scoring
Total score range= 0-23. Diagnoses (Coma, Vegetative State, Minimally Conscious State, Emerged from Minimally Conscious State) are derived directly from subscale scores.
Psychometric Properties
Selected from a field of 14 instruments based on criteria originally developed by the American Academy of Neurology and recently modified by the American Congress of Rehabilitation Medicine. The three selection criteria weighted most heavily were: a) acceptable psychometric characteristics, b) published record of clinical utility for diagnosis, prognosis and outcome monitoring, and c) ease of use.
