The Study On Decision-making Of College Students With Deviant Personality

Objective:The research uses IGT(Iowa Gambling Task)as the research paradigm to explore the decision-making function of college students with deviant personality.Method:Sampling 395 college students by easy way,first screen the sample by PDQ-4~+(Personality Diagnostic Questionaire),and then use SCID-II(Structured Clinical Interview for DSM-IV Axis II Personality Disorders)revised by yunfei Dai to do further assess.Divide the sample into two group:one is the group with deviant personality and the anther is a control group with healthy ones in.There are 55 cases in group with deviant personality and 31 cases in control group.Assess two groups with PID-5(Personality Inventory for DSM-5)and IGT.Compared the results from IGT of the two groups;correlation analysis were conduct between personality and IGT.Results:(1)The two groups gradually reduced choosing card A(F=18.17,P<0.01),increased choosing card D(F=12.93,P<0.01)during the IGT.(2)The deviant personality group showed significantly higher ratio of A/(A+B)than the control group(t=-2.24,P=0.03).In Block2 of IGT,the deviant personality group chose more card A than the control group significantly(t=-2.38,P=0.02).(3)In IGT,there was no difference between male's and female's(A+B)-(C+D)(t=1.87,P=0.07).(4)The students whose fathers were at different education levels showed significant differences in(A+B)-(C+D)of IGT(F=-2.52,P<0.05).(5)There was a significant positive correlation(P<0.01,r=0.38)between antagonism dimension and(A+B)-(C+D);Antagonism dimension entered the regression equation of(A+B)-(C+D)(R~2=0.14,P<0.01);The antagonism dimension plays a complete mediating effect between borderline deviant personality and decision-making.Conclusion:(1)The deviant personality college students have decision-making deficiency;and no gender difference was found in the decision-making deficiency.(2)The decision-making deficiency in deviant personality college students was associated with antagonism dimension.(3)Father's education level may affect the one's decision making.
