Abstract

Survey instruments used in medical research are usually taken from foreign sources. Results gained by utilization of these instruments are related to the success of the treatment and to benefits that such intervention brings to the patient. However, the information about the methods of localization and interpretation of the instrument and the methods how its validity was proved within the new (and usually different) context is missing. The aim of this study is to describe the process of validization of the Osteoarthritis Knee and Hip Quality of Life – OAKHQOL questionnaire. This instrument is focused on evaluation of the quality of life of persons with osteoarthritis. Psychometric features of the questionnaire was tested by Cronbach’s´ alpha coefficient, by exploratory factor analysis and by parallel tests of correlations with Short Form 36 Health Survey Questionnaire – SF-36 and with selected codes of International Classification of Functioning, Disability and Health (ICF). The text points-out the key steps of the validization procedure and identification of factors that might determine the findings. As a result of this study, OAKHQOL questionnaire is recommended for practical applications.
