目的 汉化癌症信息超载量表（cancer information overload scale,CIOS），并检验其在血液恶性肿瘤患者中的信效度，为评估相关患者信息超载提供客观的测量工具。方法 依据Brislin翻译模型对原量表翻译及回译，在文化调适和预调查后形成中文版CIOS。采用方便抽样法选择武汉某2所三级甲等医院的血液恶性肿瘤患者212名进行问卷调查。通过项目分析检验各条目在量表中的适切程度；邀请7位专家对量表内容效度进行评价，并采用验证性因子分析评价量表的结构效度；通过重测信度、Cronbach’s ɑ系数及折半信度系数来评估量表的信度。结果 中文版CIOS是由8个条目组成的单维度量表，项目分析结果表明具有良好的区分度且量表测量属性的一致性较高，内容效度指数为0.965，条目的内容效度指数为0.857~1.000。使用验证性因子分析进行模型拟合，各指标均达到可接受水平。量表的重测信度、Cronbach’s ɑ系数及折半信度分别为0.827、0.797和0.768。结论 中文版CIOS具有良好的信效度，可用于血液恶性肿瘤患者信息超载水平的评估。

Objective To translate the cancer information overload scale (CIOS) into Chinese，to test its reliability and validity in patients with hematologic malignancies，and to provide an objective measurement tool for assessing information overload in related patients.Methods The original scale was translated and back-translated according to the Brislin translation model.After cultural adaptation and pre-survey，the Chinese version of CIOS was formed.A convenience sampling method was used to select 212 patients with hematological malignancies from two tertiary A hospitals in Wuhan for questionnaire survey.Project analysis was used to test the appropriateness of each item in the scale;seven experts were invited to evaluate the content validity of the scale，and confirmatory factor analysis was used to evaluate the structural validity of the scale;the reliability of the scale was evaluated by test-retest reliability，Cronbach’s α coefficient，and split-half reliability coefficient.Results The Chinese version of CIOS was a single-dimensional scale consisting of 8 items.The project analysis results showed good discrimination and high consistency of the measurement attributes of the scale.The content validity index was 0.965，and the content validity index of each item was 0.857 to 1.000.Using confirmatory factor analysis to fit the model，all indicators reached acceptable levels.The test-retest reliability，Cronbach’s α coefficient，and split-half reliability coefficient of the scale were 0.827，0.797，and 0.768，respectively.Conclusions The Chinese version of CIOS has good reliability and validity and can be used to assess the information overload level of patients with hematological malignancies.
