Lee版疲劳视觉模拟量表汉化及在急性胰腺炎患者中的信效度检验

The Chinese version of Lee's Visual Analogue Scale for Fatigue and its reliability and validity in patients with acute pancreatitis

目的:汉化Lee版疲劳视觉模拟量表(VAS-F),在急性胰腺炎患者中检验其信效度。方法:对Lee版VAS-F进行翻译、回译和文化调试,形成中文版VAS-F,通过专家咨询法评价其内容效度。采用便利抽样法,选择2019年11月—2020年12月在遵义医科大学附属医院肝胆外科住院的322例急性胰腺炎患者,采用一般资料调查表、中文版VAS-F和中文版慢性病治疗功能评估疲劳量表(FACIT-F)进行调查。采用区分度检验法进行项目分析,通过Cronbach'sα系数、内容效度指数、探索性因子分析、Pearson相关分析评价中文版VAS-F信效度。结果:中文版VAS-F量表包含疲劳程度(13个条目)和能量等级(5个条目)2个子量表;总量表Cronbach'sα系数为0.843,2个子量表的Cronbach'sα系数分别为0.965和0.959;总量表和2个子量表量表水平的内容效度指数分别为0.89、0.85和1.00,各条目的条目水平的内容效度指数为0.83~1.00;经探索性因子分析2个子量表均只提取1个公因子,方差贡献率分别为71.196%和86.135%,2个子量表各条目因子负荷分别为0.698~0.859和0.852~0.906;2个子量表得分呈负相关(r=-0.604,P<0.01);疲劳程度子量表总分与FACIT-F得分呈负相关(r=-0.897,P<0.01)。322例急性胰腺炎患者中无疲劳和轻度、中度、重度疲劳者分别为3例(0.93%)、41例(12.73%)、181例(56.21%)和97例(30.12%)。结论:汉化的中文版VAS-F具有良好信效度,可用于测量我国急性胰腺炎患者的疲劳程度和能量等级。

Objective To translate Lee's Visual Analogue Scale for Fatigue(VAS-F)into Chinese,and test its reliability and validity in patients with acute pancreatitis.Methods We 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'sαcoefficient,content validity index,exploratory factor analysis,and Pearson correlation analysis.Results The Chinese version of the VAS-F contained two subscales,namely the Fatigue Severity(13 items)and the Energy Level(5 items).The Cronbach'sαcoefficient of the total scale was 0.843,and the Cronbach'sαcoefficients 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.Conclusions The 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.
