Translation and validation of Chinese version fear of falling avoidance behaviour questionnaire
Objective To introduce and translate the fear of falling avoidance behaviour questionnaire(FFABQ)into a Chinese version and test its reliability and validity.Methods The Brislin translation model was employed to translate and back-translate the original FFABQ.The back-translated FFABQ was modified based on expert consultations and a pre-survey,followed by cultural adaptation evaluation.To assess the reliability and validity of the Chinese version FFABQ(FFABQ-CHN),a convenient sampling method was used to select a total of 269 elderly patients from a general hospital in Xi'an to participate the survey.The item analysis,content validity,exploratory factor analysis,Cronbach α coefficient,split-half reliability,test-retest reliability and paired t-test were employed in the evaluation of the reliability and validity of FFABQ-CHN.Results The Chinese version FFABQ comprised 3 dimensions of walking,daily activities and work/leisure activities,with 14 items in total.A total of 254 patients had responded to the survey.Item analysis revealed that CR values of the 14 items ranged from 3.978 to 11.755(all P<0.05),with correlation coefficients between each item and the total score of the questionnaire from 0.473 to 0.930(all P<0.001).The content validity index at the item level ranged from 0.834 to 1.000,while the content validity index at the scale level was 0.968.Exploratory factor analysis extracted three common factors,with a cumulative variance contribution rate of 85.347%.The Cronbach α coefficient,half-half reliability and test-retest reliability of the questionnaire were 0.929,0.877,and 0.954,respectively.Paired t-test indicated no significant difference between the scores(all P>0.05).Conclusions The Chinese version FFABQ demonstrates strong a reliability and validity in the assessment of activity restriction related to fear of falling in the elderly.Thus,it serves as an effective tool for medical practitioners in evaluation of the restrictions in fear-of-falling-related activities of the elderly.
