疼痛共情量表的汉化及其在医学生中的信效度检验

Reliability and validity of the Chinese version of the Empathy for Pain Scale in medical students

目的引进并汉化疼痛共情量表(the Empathy for Pain Scale,EPS),检验中文版EPS在医学生中的信效度。方法经过翻译、回译、语义分析、专家咨询及文化调试,最终确定中文版EPS条目。于2018年6—10月,采用便利抽样法,选取531名在校本科生进行问卷调查。采用相关分析法和临界比值法进行项目分析,采用内容效度、结构效度、效标关联效度进行量表的效度检验,计算Cronbach'sα系数、折半信度检验量表的内在一致性。结果中文版EPS保留原12个条目,析出2个因子,2个因子命名为身心不适反应和移情反应,累计方差贡献率为69.059%。量表各条目的内容效度为0.83~1.00,总内容效度为0.94。中文版EPS总分与中文版人际反应指针量表(IRI-C)得分呈正相关(r=0.370,P<0.01);量表的Cronbach'sα系数为0.914,身心不适反应、移情反应2个维度的Cronbach'sα系数分别为0.935和0.775,量表的折半信度为0.896。结论中文版EPS包含4个场景、2个维度,具有良好的信效度,可用于测量我国医学生的疼痛共情水平。

Objective To translate the Empathy for Pain Scale(EPS)and evaluate the reliability and validity of the Chinese version of EPS in medical students.Methods The items of the Chinese version of EPS were determined by translation,back-translation,semantic analysis,expert consultation and culture adaptation.From June to October 2018,this study selected 531 undergraduate students by convenience sampling to carry out questionnaire survey.Correlation analysis and critical ratio were used to the item analysis.Validity test was implemented with the content validity,construct validity and criterion-related validity;and internal consistency was tested with the Cronbach'sαvalue and split-half reliability.Results The Chinese version of EPS had 12 items and two factors named as the body and mind discomfort reactions and empathy reactions with 69.059%for the total variance contribution.Content validity of items ranged from 0.83 to 1.00,and the total content validity was 0.94.The total score of the Chinese version of EPS had a positive correlation with the score of the interpersonal reactivity index(IRI-C)(r=0.370,P<0.01).The Cronbach'sαvalue of the scale was 0.914;Cronbach'sαvalues of two dimensions,the body and mind discomfort reactions and empathy reactions,were 0.935 and 0.775 respectively.The split-half reliability of the scale was 0.896.Conclusions The Chinese version of EPS has four scenes and two dimensions as well as a good reliability and validity which could be used to evaluate the level of empathy for pain among medical students in China.
