临床和转化医学研究导师胜任力评价量表的汉化和信效度分析

Reliability and validity of the mandarin version of mentor competency assessment

目的引进、汉化临床和转化医学研究导师胜任力评估量表(mentor competency assessment,MCA),并对其进行信效度检验。方法2020年1月至3月,采用Brislin翻译模型进行翻译、回译,并通过专家函询和预调查对翻译初稿进行文化调适。选取北京协和医院153名临床医学博士后导师、副导师为调查对象,采用一般资料调查表和中文版MCA进行调查。对中文版MCA进行信度和效度分析。结果中文版MCA包括保持有效沟通、建立一致的预期和目标、评估学生、培养独立性、尊重多样性、促进学生的职业发展6个维度,26个条目。量表克朗巴赫系数为0.975,Spearman-Brown折半系数为0.951;量表各条目评分与总分呈正相关(r值为0.634~0.823)。量表的条目水平的内容效度指数(I-CVI)为0.6~1.0,量表水平的内容效度指数(S-CVI)为0.954。验证性因子分析结果显示,χ2自由度比(χ2/DF)为1.865,比较拟合优质指数(CFI)为0.925,非标准拟合指数(TLI)为0.914,标准化残差均方和平方根(SRMR)为0.043,近似误差均方根(RMSEA)为0.085(95%CI:0.073~0.096,P<0.01)。结论中文版MCA具有良好信度和效度,适用于我国临床和转化医学研究导师的胜任力评价。

Objective To translate the mentor competency assessment(MCA)into Mandarin,and test its reliability and validity.Methods Brislin translation model was used for translation and reverse-translation.The preliminary translation was culturally adjusted through expert committee discussions followed by a pre-tests.Mentors of clinical post-doctoral trainees at Peking Union Medical College Hospital(PUMCH)were enrolled as the survey subjects(n=153)from January 2020 to March 2020.General questionnaire and Mandarin version of MCA were used.Item analysis,reliability,and validity analysis of the Mandarin version of MCA were tested.Results The Mandarin version of MCA includes 26 items in six dimensions,including effective communication,establishing consistent expectations and goals,evaluating students,fostering independence,respecting diversity,and promoting students'professional development.Reliability analysis showed that Cronbach's coefficient score was 0.975,and split-half coefficient score was 0.951.Each item was positively correlated with the total score(r=0.634~0.823).The item content validity index(I-CVI)is 0.6~1.0,and the scale content validity index(S-CVI)was 0.954.The confirmatory factor analysis results showed that the ratio ofχ2 degrees of freedom(χ2/DF)was 1.865,the comparative fit index was 0.925,the Tucker-Lewis index(TLI)=0.914,and the standardized root mean square residual(SRMR)=0.043,and the root mean square error of approximation(RMSEA)=0.085(95%CI,0.073~0.096,P<0.01).Conclusions The reliability and validity of the Mandarin version of MCA was evaluated and the Mandarin version of MCA is competent to the evaluation of the mentor competency of clinical and translational research mentors in China.
