Abstract
ObjectiveTo translate Lee's Visual Analogue Scale for Fatigue (VAS-F) into Chinese, and test its reliability and validity in patients with acute pancreatitis.
MethodsWe performed translation, back translation and cultural debugging of Lee's VAS-F to form the Chinese version of VAS-F. The expert consultation was used to evaluate the content validity of VAS-F. Convenient sampling was used to select 322 inpatients with acute pancreatitis in the Department of Hepatobiliary Surgery in Affiliated Hospital of Zunyi Medical University from November 2019 to December 2020. The General Information Questionnaire, the Chinese version of VAS-F and the Chinese version of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) were used for investigation. The discrimination test was used for item analysis, and the reliability and validity of the Chinese version of VAS-F were evaluated through Cronbach's α coefficient, content validity index, exploratory factor analysis, and Pearson correlation analysis.
ResultsThe Chinese version of the VAS-F contained two subscales, namely the Fatigue Severity (13 items) and the Energy Level (5 items) . The Cronbach's α coefficient of the total scale was 0.843, and the Cronbach's α coefficients of the two subscales were 0.965 and 0.959, respectively. The scale-level content validity index of the total scale and the two subscales were 0.89, 0.85 and 1.00, respectively, and the item-level content validity index of each item was from 0.83 to 1.00. After exploratory factor analysis, only one common factor was extracted from the two subscales, and the variance contribution rates were 71.196% and 86.135%, respectively. The factor loads of each item of the two subscales ranged from 0.698 to 0.859 and from 0.852 to 0.906, respectively. The scores of two subscales were negatively correlated (r=-0.604, P<0.01) , and the total score of Fatigue Severity subscale was negatively correlated with the FACIT-F score (r=-0.897, P<0.01) . Among 322 patients with acute pancreatitis, there were 3 cases (0.93%) without fatigue, 41 cases (12.73%) with mild fatigue, 181 cases (56.21%) with moderate fatigue and 97 cases (30.12%) with severe fatigue.
ConclusionsThe Chinese version of VAS-F has good reliability and validity and can be used to measure the fatigue and energy level of patients with acute pancreatitis in China.
