Official Title: Validation of the Russian Version of Coma Recovery Scale-Revised (CRS-R)

Brief Summary: The purpose of this study is to validate Russian version of Coma Recovery Scale - Revised and to assess its psychometric properties.

Detailed Summary:

There is a need of validated scale for correct assessment for patients with disorders of consciousness (DOC) in Russia. One of the most detailed scales that provides robust results in these patients is the Coma Recovery Scale - Revised (CRS-r). The validated Russian version of CRS-r will be very helpful in clinical work and scientific research for making correct assessment of patients status and its changes over time in Russia and Russian-speaking countries.

The purpose of this study is to validate Russian version of CRS-R and to assess its psychometric properties.

The first step of the study was to perform translation of CRS-r from English into Russian according to the validation protocol:

  1. Double direct translation by independent translators;
  2. Combination of two Russian translations;
  3. Reverse translation by native English speaker.

Final Russian version and back-translated version of the Scale were approved by the original author, Dr. J. Giacino. He approved the original validation study protocol as well.

To validate Russian version of CRS-r and to assess its psychometric properties the investigators will perform an observational study on 60 adults with disorders of consciousness of different etiology on different period of recovery after coma. It is planned to include patients with various states of consciousness (e.g., vegetative state, minimally conscious state "minus" and minimally conscious state "plus") in balanced proportions.

Every patient will be examined by two independent researchers on the
