Objective: To test the reliability and validity of Meaningful Life Measure-Chinese Revised (MLM-CR) in Chinese college students.
Methods: A total of 1035 college students were evaluated with MLM-CR, Satisfaction with Life Scale (SWLS), Purpose in Life (PIL) and Patient Health Questionnaire-2 (PHQ-2), and 120 of the students were examined with PIL-SF twice.
Results: All the items in MLM-CR had good discrimination indexes (r=0.753-0.838, P<0.001). Confirmatory factor analysis confirmed the hypothesized five-factor model of MLM-CR (Χ2/df=3.4, GFI=0.946, AGFI=0.924, RMR=0.069, NFI=0.953, CFI=0.966, RMSEA=0.048). The total internal consistency reliability of MLM-CR was 0.942, and the alpha coefficients of the 5 dimensions ranged from 0.782 to 0.877; the total split-half reliability was 0.920, and the split-half reliability of the 5 dimensions ranged from 0.752 to 0.830; the total test-retest reliability was 0.871, and the test-retest reliability of the 5 dimensions ranged from 0.783 to 0.805. The criterion validity of MLM-CR in correlation with SWLS, PIL and PHQ-2 was 0.66, 0.755 and -0.388, respectively (P<0.01). The Average score of MLM-CR of the college students was 5.20∓0.90, and the scores were significantly higher in female students than in the male students (P<0.001).
Conclusion: MLM-CR has good psychometric properties for application in comprehensive evaluation of personal meaning in life.
目的: 评价中文修订版生命意义量表 (MLM-CR) 测量中国大学生生命意义感的适用性。
方法: 用MLM-CR、生命满意度量表 (SWLS)、生活目的量表 (PIL) 和病人健康问卷-2(PHQ-2) 对1035名大学生进行施测，对MLM-CR进行项目分析、验证性因素分析和信度、效度检验。
结果: (1) MLM-CR的23个项目鉴别指数均在0.7以上 (r=0.753~0.838，P < 0.001)；(2) 验证性因素分析所得结构方程模型具有良好的拟合度 (χ2/df=3.4; GFI=0.946；AGFI=0.924；RMR=0.069；NFI=0.953；CFI=0.966；RMSEA= 0.048)，结果支持MLM-CR具有兴奋感、成就感、原则性、目的性、价值感的五因子结构；(3) MLM-CR总量表Cronbach α系数为0.942，各因子的Cronbach a系数在0.782~0.877之间；MLM-CR总量表的分半信度为0.920，各因子的分半信度在0.752~0.830之间；MLM-CR总量表的重测信度为0.871，各因子的重测信度在0.783~0.805之间；(4) MLM-CR与SWLS，PIL和PHQ-2的效标相关分别为0.666，0.755，-0.388；(5) 大学生MLM-CR总均分为 (5.20±0.90)，总体生命意义感处于中等偏上水平，女生的生命意义感高于男生 (P < 0.001)。
结论: MLM-CR具有良好的信、效度，适用于综合地反映个体的生命意义感。
