ABSTRACT
Objective:To explore the effects of childhood trauma on depression of college students and the role of depletion sensitivity and self-control in it.Methods:A total of 1 678 freshmen and sophomores from a medical university in Guangzhou were investigated by childhood trauma questionnaire(CTQ), Beck depression inventory-Ⅱ(BDI-Ⅱ), depletion sensitivity scale(DSS) and self-control scale(SCS) through random cluster sampling. The mediating effect of depletion sensitivity and moderating effect of self-control were examined by SPSS 26.0 macro program PROCESS V2.13.Results:(1)The total scores of CTQ and BDI-Ⅱ in college students were (34.56±7.03) and ( M( QR): 5.00(7.00)) respectively, and the scores of DSS and SCS were (41.78±12.21) and (40.02±8.15) respectively. (2)Childhood trauma was positively correlated with depletion sensitivity ( r= 0.20, P<0.01) and depletion sensitivity was positively correlated with depressive symptoms ( r=0.48, P<0.01). There was a negative correlation between self-control and depressive symptoms ( r=-0.49, P<0.01). (3)Depletion sensitivity partly mediates the relationship between childhood trauma and depressive symptoms. The direct effect (effect size=0.28) and mediating effect (effect size=0.07) accounted for 80% and 20% of the total effect (effect size=0.35), respectively. (4)Self-control moderated the path between depletion sensitivity and depressive symptoms. Conclusion:Childhood trauma can indirectly affect college students′ depressive symptoms through depletion sensitivity, and the partial mediatory role of depletion sensitivity is also moderated by self-control.
ABSTRACT
Objective:To validate the Chinese Version of Depletion Sensitivity Scale (DSS) and test its validity and reliability.Methods:A sample of 499 postgraduates coming from a university in Beijing was investigated with preliminary questionnaire,249 of them were assessed for exploratory factor analysis(EFA) and 250 of them were assessed for confirmatory factor analysis (CFA) and testing of validity and reliability.The criterion validity was tested with the Self-Regulatory Fatigue Scale (SRF-S),Dual-Mode of Self-Control Scale (DMSC-S) and Adolescent Self-rating Life Events Check-list (ASLEC).Totally 280 students were retested for test-retest reliability with 2 week interval.Results:DSS was composed of 8 items in two factors,which were cognitive factor and behavioral factor.The two factors explained 60.7％ of the variances.The confirmatory factor analysis identified a two factor model (x2/df=4.18,RMSEA =0.09,NFI =0.95,NNFI =0.94,CFI =0.96,IFI =0.96,GFI =0.96,SRMR =0.05).The scores of depletion sensitivity were positively correlated with the scores of cognitive fatigue,behavioral fatigue,emotional fatigue poor control,punished,loss,relationship pressure and adaption problem (r =0.13-0.55,Ps ＜0.001).The Cronbach α coefficients were 0.80 for the total questionnaire and 0.79 and 0.73 for the two factors.The test-retest reliability were 0.52 for the total questionnaire and 0.46 and 0.58 for the two factors.Conclusion:It suggests that the Chinese version of Depletion Sensitivity Scale (DSS) is reliable and valid enough to be applicable to measure the depletion sensitivity of Chinese graduate students.
