个人意义指数量表中文版用于医学生的信度和效度检验

摘要

[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PM I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 in-vestigated 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.Ex-ploratory factor analysis showed that PMI had two factors:sense of life value and clear sense,which explained 56.71% of the total va-riance.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 consis-tency 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.
