Validity and reliability of the Chinese version of the Self-Regulatory Fatigue Scale in young adults / 中国心理卫生杂志

ABSTRACT

Objective:To evaluate the reliability and validity of the Chinese version of the Self-Regulatory Fa-tigue Scale (SRF-S)in Chinese young people.Methods:A sample of 553 young people from a university and a state-owned enterprise was administrated with the SRF-S,the Simplified Coping Style Questionnaire (SCSQ)and the Dual-Mode Self-Control Scale (DMSC-S).Item analysis was conducted to identify valid items and revise the scale.Then the construct validity of the revised scale was tested through confirmatory factor analysis.Finally,a sam-ple of 238 graduate students was retested two weeks later to examine the reliability of the scale.Results:Item analy-sis showed that the SRF-S had satisfactory item discrimination (r >0.38).Confirmatory factor analysis showed that the whole scale had a three-order factor and good construct validity (χ2 /df=5.08,RMSEA =0.09,NFI =0.90, NNFI =0.90,CFI =0.92,IFI =0.92,GFI =0.90)after removing 2 items with factor loadings lower than 0.32,and the range of factor loading was between 0.37 and 0.71.The SRF-S total and subscale scores were positively corre-lated with the scores of negative coping and poor control (r =0.25 -0.58,Ps <0.001),and were negatively associ-ated with the scores of positive coping and good self-Control (r =-0.22 --0.47,Ps <0.001).The Cronbach's αcoefficients were 0.84 for the total scale,and 0.64 to 0.69 for the three subscales,respectively;the test-retest relia-bility coefficients were 0.73 for the total scale,and 0.62 to 0.67 for the three subscales,respectively.Conclusion:It suggests that the Chinese version of SFR-S could be used as an effective and reliable tool for assessing self-regu-latory fatigue state among Chinese young people.
