Development of the ego depletion aftereffects scale in postgraduates / 中华行为医学与脑科学杂志

ABSTRACT

Objective To develop the ego depletion aftereffects scale (EDA-S) and test its validity and reliability.Methods Based on literature analysis and the open questionnaire survey this study compiled the preliminary questionnaire.A sample of 801 subjects coming from a university in Beijing was investigated with preliminary questionnaire and 406 students were retested for test-retest reliability with 2 week interval.Results The EDA-S was composed of 38 items in nine factors,which were emotional regulation difficulty,social withdrawal,low efficacy,working memory impairment,low processing fluency,work burnout,fatigue,somatic distress and low adherence.The eleven factors explained 72.09％ of the variances.Furthermore,the result of CFA indicated that the model fitted the data with well construct validity(x2 =1744.62,df=629,x2/df =2.77,RMSEA =0.06,NFI =0.98,NNFI =0.98,CFI =0.98,IFI =0.98,GFI =0.85,SRMR =0.05) and its factors scores were positively correlated with the SFR-S scores(r=0.31-0.59,P＜0.001).The Cronbach α coefficients were 0.95 for the total questionnaire and 0.73-0.91 for the eleven factors.The test-retest reliabilities were 0.60 for the total questionnaire and 0.26-0.57 for the nine factors.Conclusion It suggests that the EDA-S is reliable and valid enough to be applicable to measure the depletion degree of adolescents.
