个人意义指数量表中文版用于医学生的信度和效度检验

Reliability and validity test of Chinese version of Personal Meaning Index (PMI) in medical students

[目的]翻译修订个人意义指数(PMI)量表,评价其中文版在本科医学生中的信度和效度。[方法]于2016年9月—10月采用分层整群抽样方法,使用PMI量表中文版和生命意义感量表对436名医学生进行问卷调查,对调查数据分别进行效度检验和信度分析。[结果]PMI量表中文版中所有条目都具有较高的鉴别度;探索性因子分析表明PMI因子有两个(生命价值感和明确目标感)解释方差总变异的56.71%;验证性因子分析显示两因子模型的拟合度指标均优于单因子模型;PMI中文版与效标生命意义感量表相关(相关系数为0.249~0.959,P<0.01);量表的内部一致性系数为0.925,重测信度为0.890。[结论]PMI量表中文版在对医学生的测评中显示具有良好的信度和效度。

Objective:To translate and revise the Personal Meaning Index(PMI),and evaluate the reliability and validity of the Chinese version in undergraduate medical students.Methods:Using stratified cluster sampling method,a total of 436 medical students were investigated by the Chinese version of PMI and the Meaning in Life Questionnaire(MLQ).The validity of the survey data was analyzed by validity test and reliability analysis.Results:All the entries in the Chinese version of PMI had a higher degree of discrimination.Exploratory factor analysis showed that PMI had two factors:sense of life value and clear sense,which explained 56.71% of the total variance.The confirmatory factor analysis showed that the fitting index of the two factor model was better than that of the single-factor model.The correlation between Chinese version of PMI and MLQ was significant(r=0.249-0.959,P<0.01).The internal consistency coefficient of the Chinese version of PMI was 0.925,and the retest reliability was 0.890.Conclusions:The Chinese version of PMI showed good reliability and validity in the evaluation of medical students.
