Abstract:
Objective:To translate the Fremantle Knee Awareness Questionnaire (FreKAQ) into Chinese, and test its reliability and validity in patients with knee osteoarthritis.Methods:The English version of FreKAQ was translated, back translated, cross-cultural debugging, and pre survey interviews to determine the Chinese version of FreKAQ. From June 2017 to December 2020, a total of 200 patients with knee osteoarthritis admitted to the Department of Orthopedics of Lu'an Hospital of Anhui Medical University were selected by convenience sampling for investigation to test the reliability and validity of the Chinese version of FreKAQ. The critical ratio method was used to screen items, and the validity of the questionnaire was tested by content validity index, exploratory factor analysis and confirmatory factor analysis. Cronbach's α coefficient, split half reliability coefficient and retest reliability coefficient were used to test the reliability of the questionnaire.Results:Two common factors were extracted from the Chinese version of FreKAQ by the maximum variance orthogonal rotation method, and the cumulative variance contribution rate was 83.541%, including nine items. Cronbach's α coefficient of the total questionnaire was 0.905, Cronbach's α coefficients of each dimension were 0.913 and 0.905 respectively, the split half reliability coefficient of the total questionnaire was 0.903, and the retest reliability coefficient of the total questionnaire was 0.923. The content validity index of the average scale level was 0.906, and the content validity index of the item level was 0.885 to 1.000. The confirmatory factor analysis showed that the overall model fitted well.Conclusions:The Chinese version of FreKAQ has good reliability and validity, which can be used to assess the symptoms of knee awareness impairment in Chinese patients with knee osteoarthritis.
