决策参与量表的汉化及在颅内肿瘤患者家属中的信效度检验

Validity and reliability of the Chinese version of the Decisional Engagement Scale in family members of patients with intracranial cancers

目的汉化决策参与量表,并及在颅内肿瘤患者家属中检验其信效度。方法基于Brislin翻译模式对决策参与量表进行翻译、回译和跨文化调试,形成中文版决策参与量表。2021年9月—2022年1月,采用便利抽样法,选取乌鲁木齐市222名颅内肿瘤患者家属进行调查,2周后从中随机抽取30名家属进行重测,检验量表的信效度。结果中文版决策参与量表共有10个条目,探索性因子分析提取出4个公因子,累计方差贡献率为84.078%。量表的Cronbach’sα系数为0.850,折半信度系数为0.819,重测信度系数为0.809。量表的条目内容效度指数为0.833~1.000,全体一致内容效度指数为0.900。验证性因子分析结果显示,卡方自由度比值为2.967、拟合优度指数为0.929、相对拟合指数为0.956、规准适配指数为0.936、非规准适配指数为0.929、增量拟合指数为0.957、近似误差均方根为0.094。结论中文版决策参与量表具有良好的信效度,可以作为肿瘤患者家属医疗决策参与的评估工具。

Objective To test the reliability and validity of Decisional Engagement Scale for family members of cancer patients(DES-10)in Chinese version.Methods The Chinese version of DES-10 was translated,back translated and modified for cultural adaptation according to Brislin translation model.From September 2021 to January 2022,222 family members of patients with intracranial tumor in Urumqi were selected by convenience sampling,and 30 family members of them were randomly selected to retest after 2 weeks to test the reliability and validity of the scale.Results The Chinese version of the scale has 10 items.The exploratory factor analysis extracted 4 common factors,and the cumulative variance contribution rate was 84.078%.The Cronbach’sαcoefficient of the scale was 0.850;the split-half reliability was 0.819;the test-retest reliability was 0.809.The Item-level Content Validity Index was 0.833~1.000;the Scale-level Content Validity Index was 0.900.The confirmatory factor analysis showed:χ2/df=2.967,Goodness Fit Index=0.929,Comparative Fit Index=0.956,Normed Fit Index=0.936,Tucker-Lewis Index=0.929,Incremental Fit Index=0.957,Root Mean Square Error of Approximation=0.094.Conclusion The Chinese version of DES-10 has good reliability and validity.It could be used as an effective tool to evaluate the medical decisional engagement for family members of cancer patients.
