癌症患者睡眠信念与态度量表的汉化及信效度检验

Chinese translation and reliability and validity testing of Dysfunctional Beliefs and Attitudes about Sleep Scale for Cancer Patients

目的:汉化癌症患者睡眠信念与态度量表(C-DBAS-14)并检验其信效度。方法:依据Brislin翻译模型对韩文版C-DBAS-14进行翻译、回译及文化调适,形成中文版C-DBAS-14。采用便利抽样法,选取2022年10月-2023年5月在安徽医科大学第一附属医院住院的361例癌症患者为研究对象,采用一般资料调查表、中文版C-DBAS-14、失眠严重程度指数量表、医院焦虑抑郁量表对患者进行调查,以评价量表的信效度。量表的项目分析采用相关系数法及临界比值法;采用结构效度、内容效度及聚合效度评价量表的效度;采用Cronbach's α系数和组内相关系数评价量表的信度。结果:本研究共发放问卷361份,回收有效问卷356份,问卷有效回收率为98.6%(356/361)。中文版C-DBAS-14包含4个维度,共14个条目。量表水平的内容效度指数为0.976,条目水平的内容效度指数为0.833~1.000。探索性因子分析共提取出4个公因子,解释总方差的78.8%。验证性因子分析显示,卡方自由度比为1.286,比较拟合指数为0.991,拟合优度指数为0.945,递增拟合指数为0.991,非规准适配指数为0.988,近似误差均方根为0.036。量表总的Cronbach's α系数为0.874、组内相关系数为0.863。量表得分与失眠严重程度指数得分、医院焦虑抑郁量表得分均呈负相关( r值分别为-0.734、-0.639, P<0.01)。 结论:中文版C-DBAS-14具有良好的信度和效度,可作为我国癌症患者不合理睡眠信念的评估工具。

ObjectiveTo translate the Dysfunctional Beliefs and Attitudes about Sleep Scale for Cancer Patients(C-DBAS-14)into Chinese and test its reliability and validity.MethodsThe Korean version of C-DBAS-14 was translated,back-translated,and culturally adapted into Chinese based on Brislin's translation model,forming the Chinese version of C-DBAS-14.From October 2022 to May 2023,361 hospitalized cancer patients at the First Affiliated Hospital of Anhui Medical University were selected as research objects by convenient sampling method.They were surveyed using a general information questionnaire,the Chinese version of C-DBAS-14,the Insomnia Severity Index(ISI),and the Hospital Anxiety and Depression Scale(HADS)to evaluate the reliability and validity of the scale.The scale's item analysis was based on correlation coefficients and critical ratio values;structural validity,content validity,and convergent validity were used to evaluate the scale's validity;Cronbach'sαcoefficient and intraclass correlation coefficient were used to assess its reliability.ResultsA total of 361 questionnaires were distributed,356 were effectively returned,with an effective response rate of 98.6%(356/361).The Chinese version of C-DBAS-14 contained 14 items across four dimensions.The scale-level content validity index was 0.976,and the item-level content validity index ranged from 0.833 to 1.000.Totally four common factors were extracted in exploratory factor analysis,explaining 78.8%of the total variance.Confirmatory factor analysis showed a Chi-square/degrees of freedom ratio of 1.286,comparative fit index of 0.991,goodness of fit index of 0.945,incremental fit index of 0.991,Tucker-Lewis index of 0.988,and root mean square error of approximation of 0.036.The total Cronbach'sαcoefficient of the scale was 0.874,and the intraclass correlation coefficient was 0.863.The C-DBAS-14 score was negatively correlated with the ISI and HADS scores(r=-0.734,-0.639;P<0.01).ConclusionsThe Chinese version of C-DBAS-14 has good reliability and validity and can be used as an assessment tool for irrational sleep beliefs in Chinese cancer patients.
