Translation and Validation of Quality of Life Instruments

PREFERENCE PRO, Inc. (formerly a division of EVIDENCE Clinical and Pharmaceutical Research, LLC) was the first clinical research group in Russia to conduct Quality of Life studies.

Our experience in this field was gained through extensive collaboration with MAPI Research Institute (Lyon, France), The Center on Outcomes, Research and Education - CORE (Evanston, Illinois, USA), New England Medical Center/ Health Assessment Lab (Boston, Massachusetts, USA) and other organizations. Since 1993, we have translated hundreds QoL instruments into Russian and other Eastern European languages and validated them in various patient populations.

If you wish to use the Russian Version of the SF-36 Health Survey please download and sign the User Agreement (Russian, Rich Text Format (rtf), 40 Kb or Portable Document Format (pdf), 75 Kb) and send it to the contact person named in the Agreement. Please note that we DO NOT process questionnaire data.
