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.
