ABSTRACT
Objective To examine the differences and influential factors of ego-depletion source and its aftereffects between Chinese and non-Chinese graduate students (international graduate students) enrolled graduate programs in Chinese Universities.Methods Three different questionnaires were employed to assess the current situation of ego-depletion of 647 graduate students:demographic information questionnaire,Ego Depletion Source Scale (EDS-S) in postgraduates and Ego Depletion Aftereffects Scale (EDA-S).Collected data were analyzed by an independent samples t test,correlation analysis and multiple regression analysis.Results ①The scores of non-Chinese graduate students in China (83.59±25.97) were higher than those of Chinese students (67.39± 25.46) on EDA-S in postgraduates,the difference was significant (P＜ 0.01).②The scores of non-Chinese graduate students (132.71± 19.89) were higher than those of Chinese students (104.15±33.02) on EDS-S,the difference was significant (P＜0.01).③Of all the 11 dimensions of EDS-S,social distress,challenging task,thought suppression,compulsive task positively anticipated the EDA-S for Chinese graduate students (R2adj =0.584,R2adj =0.450,R2adj =0.624,R2adj =0.615,P＜0.05) and social distress,decision making,compulsive task positively anticipated the EDA-S for non-Chinese graduate students (R2adj =0.698,R2adj =0 603,R2adj =0.668,P＜0.05).Conclusion Compared to Chinese graduate students,egodepletion source and ego depletion aftereffects of non-Chinese graduate students were higher.Of all the 11 dimensions of EDS-S,social distress,challenging task,thought suppression,compulsive task was in high correlation with EDA-S for Chinese graduate students,and social distress,decision making,compulsive task was in high correlation with EDA-S for non-Chinese graduate students.
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.
