Abstract:

BACKGROUND: There are more and more researches on the risk factors of knee osteoarthritis at home and abroad, but there is no unanimously recognized questionnaire. Knee Osteoarthritis questionnaire can be used for a wide range of clinical epidemiological investigation, which can provide relative basis for the further clinical research and treatment.
OBJECTIVE: To design a questionnaire about knee osteoarthritis for analyzing risk factors of knee osteoarthritis, and to assess its reliability and validity.
METHODS: Thirty patients with knee osteoarthritis in the First Affiliated Hospital of Jinan University were collected as the research subjects, then a unified questionnaire was designed and the proper statistical methods were used to assess its reliability and validity.
RESULTS AND CONCLUSION: The questionnaire was formulated by seven aspects contained 17 items in all, the general Cronbach’s α coefficient of this questionnaire was 0.974, and the analysis of the content validity showed that the subjects can represent the measurement content with high content validity. The questionnaire about knee osteoarthritis has high reliability and validity, and can be used for a wide range of epidemiological investigation in clinical practice.
