Revision of trait self-control scale for chinese college students / 中华行为医学与脑科学杂志

ABSTRACT

Objective To revise the trait self-control scale for Chinese college students.Methods According to the theory,12 items were selected,then data were collected from a sample of 549 and 133 college students of Harbin.Explorer Factor Analysis,Confirmatory Factor Analysis,reliability test and validity test were used.Results ①Trait self-control scale for college students included eight items,two dimensions were restrained and impulsivity,two dimensions can explain 42.90％ of the total variance.②Confirmatory Factor Analysis showed that the two-dimensional structure was reasonable (x2/df =1.24,CFI =0.97,GFI =0.96,AGFI =0.92,IFI =0.97,TLI =0.96,RMSEA =0.04).③The restrained factor scores were positively correlated with satisfaction of life scores and adaption scores(r=0.23,0.48,P＜0.01),while negatively correlated with negative affect (r=-0.19,P ＜0.01).The impulsivity factor scores were negatively correlated with satisfaction of life scores and adaption scores (r=-0.18,-0.34,P＜0.01),while positively correlated with negative affect(r=0.22,P＜0.01).④The composite reliability coefficients of the scales were goodthe coefficient of the subscale restraint was 0.69,and the coefficient of subscale of impulsivity was 0.64,the coefficient of the whole scale was 0.80.The two months test-retest reliability coefficient of 133 subjects was 0.66.Conclusion The revised scale of trait self-control scale has good psychometric quality and can be used in Chinese college students.
