Among surveyed patients with II radiological stage (R) prevailed. The assessment constructive validity questionnaires HAQ, WOMAC and the brief form of a questionnaire of pain Me Gill was carried out by the multifactorial analysis with allocation of the main components, a method of "known groups" on the basis of construction of hypotheses, the correlation analysis with external criteria and separate clinical-tool parameters.
