大学生活力量表的编制

目的:编制大学生活力量表(VSUS)并检验其效度和信度。方法:在活力的自由语词联想、大学生活力观调查等定性分析的基础上,构建大学生活力的理论结构并编制VSUS初稿;对634名大学生初测,经条目分析和探索性因子分析形成量表二稿;对1503名大学生正式施测,进行验证性因子分析及量表的内部一致性信度检验,并选取其中100人进行2周后的重测;使用主观活力量表(SVS)进行校标效度检验。结果:量表共39个条目,分为7个因子,可解释的总变异为69.71%;验证性因子分析显示各因子模型拟合良好(CMIN/DF=4.29,CFI=0.96, GFI=0.91,AGFI=0.89,PGFI=0.74,NFI=0.94,IFI=0.96,TLI=0.95,RMSEA=0.05);量表总分及7个因子得分均与SVS总分正相关(ICC=0.41～0.71)。量表总分及7个因子得分的内部一致性信度为0.87～0.97,重测信度(ICC)为0.44～0.65。结论:大学生活力量表是测量大学生活力水平的有效工具。

Development of the Vitality Scale for University Students

Objective:To develop the Vitality Scale for University Students(VSUS)and test its validity and reliability.Methods:The first draft scale was developed based on the qualitative analysis of the free lexical association for vitality and the survey on college students'vitality.Totally 634 university students were recruited to complete the pre-investigation,so as to develop a revised version of scale based on the data collected via item analysis and exploratory factor analysis.Totally 1503 university students were tested for further confirmatory factor analysis and internal consistency reliability test.The test-retest reliability was examined with a sample of 100 residents from all participants after 2 weeks.The criterion validity was tested with the Subjective Vitality Scale(SVS).Results:The scale had a total of 39 entries,divided into 7 factors.The cumulative contribution of the variance explained was 69.71%.Confirmatory factor analysis showed that the factor model of each dimension fit well(CMIN/DF=4.29,CFI=0.96,GFI=0.91,AGFI=0.89,PGFI=0.74,NFI=0.94,IFI=0.96,TLI=0.95,RMSEA=0.05).The correlation coefficient(ICC)of the total score of the scale and the scores of the seven factors with the SVS total score ranged from 0.41 to 0.71.The internal consistency reliability of the total score of the scale and the scores of the seven factors ranged from 0.87 to 0.97.The test-retest reliability(ICC)ranged from 0.44 to 0.65.Conclusion:The Vitality Scale for University Students(VSUS)is an effective tool to measure the level of vitality of Chinese university students.
