简洁版平衡评定系统测试量表汉化及在慢性阻塞性肺疾病患者中的信度与效度检验

Validation of the Chinese version of the Brief-BESTest scale and the reliability and validity of patients with chronic obstructive pulmonary disease

目的:对简洁版平衡评定系统测试量表(Brief-BESTest)进行中文版汉化并在COPD患者中进行信效度检验。方法:通过取得原作者授权-翻译-综合-回译-专家评议对英文版Brief-BESTest量表进行汉化,选择20例COPD患者进行预实验,对问卷进行修改和文化调试后,另择150例COPD患者进行测试,检测中文版Brief-BESTest量表的信效度,利用Spearman相关分析测试Brief-BESTest量表与Morse评估量表的相关性。结果:中文版Brief-BESTest量表共有6个条目,其中两个需进行双向计分,探索性因子分析,共提取了3个因子,累计方差贡献率为84.020%。总量表的Cronbachα系数为0.904,折半信度系数为0.836,重测信度为0.936(P<0.01,95%CI=[0.839,0.975]),与Morse评估表之间呈显著的负相关(r=-0.494,P<0.01)。结论:中文版Brief-BESTest量表具有良好的信效度,适合在中国文化背景下测试COPD患者的平衡能力。

Objective: To perform a simplified Chinese version of the balance-evaluation system test scale (Brief-BESTest)and to test the reliability and validity for COPD patients.Method:The Chinese version of the Brief-BESTest scale was completed by obtaining the author's authorizationtranslation-synthesis-back-translation-expert review. Twenty patients with COPD were selected for pre-experiment.After the questionnaire was modified and culturally debugged, another 150 COPD Patients were tested for thereliability and validity of the Chinese version of the Brief- BESTest scale.Spearman correlation analysis wasused to test the association of the Brief-BESTest scale with the Morse assessment scale.Result:The Chinese version of Brief-BESTest had 6 items in total, of which two required bidirectional scoring.Exploratory factor analysis,three factors were extracted and the cumulative variance contribution rate was 84.020%. The Cronbach's alpha coefficient of the total scale was 0.904, the coefficient of half-value reliabilitywas 0.836 and the test-retest reliability was 0.936 (P<0.01,95% CI=[0.839,0.975]), which was significantly negativelycorrelated with the Morse evaluation table (R=-0.494, P<0.01).Conclusion:The Chinese version of the Brief-BESTest scale has a good reliability and validity and is suitablefor testing the balance of COPD patients in the Chinese culture.
