Reliability and Validity of the Chinese Version and Brief Version of the Multidimensional Self-Control Scale
Objective:To revise the Chinese version of the Multidimensional Self-Control Scale(MSCS)and its abbrevi-ated version.Methods:A sample of 556 undergraduate and graduate students from Zhejiang University,as well as some ex-ternal trainees,was surveyed.From this sample,282 individuals were selected to take the Chinese version of the Self-Con-trol Scale(SCS)for criterion validity verification.A subset of 151 participants from the 556 was retested after an interval of 3 weeks.Results:The results of the confirmatory factor analysis indicated that the bi-factor model of the revised MSCS Chinese version had the best fit(x2/df=2.144,GFI=0.910,NFI=0.864,IFI=0.922,TLI=0.907,CFI=0.921,RMSEA=0.047,SRMR=0.047).The brief version's bi-factor model also showed a good fit(x2/df--3.937,GFI=0.977,NFI=0.923,IFI=0.941,TLI=0.860,CFI=0.940,RMSEA=0.076,SRMR=0.040).The Cronbach's coefficients of each dimension of the revised MSCS Chinese version ranged from 0.721 to 0.826(brief version:0.628 and 0.596).After 3 weeks later,the test-retest reli-ability of each dimension ranged from 0.615 to 0.850(brief version:0.792 and 0.649).Using the total score and dimensional scores of the Chinese revised Self-Control Scale(SCS)as criteria,their correlations ranged from 0.447 to 0.757,P＜0.01(for the brief version:0.437 to 0.746,P＜0.01).The correlations between the total scores and the scores of the two dimensions for the abbreviated and full versions were 0.913,0.885,and 0.858,respectively.Conclusion:Both the revised MSCS Chinese version and its brief version have good reliability and validity.
