The Relationship Between Reinforcement Sensitivity And Impulsiveness Among Internet Gaming Disorder Of Undergraduate And High School Student

Objective:(1)To provide a reliable measuring tool to further explore the relationship between Internet game disorder(IGD)and reinforcement sensitivity,we test reliability and validity of Behavior Inhibition System/Behavior Activation System scales(BIS/BAS,24 items).(2)To explore the relationship between Internet game disorder(IGD)and reinforcement sensitivity,impulsiveness of teenagers by using the Young's Internet Addiction Test(IAT),Online Game Addiction Questionnaire,BIS/BAS scales and Barratt impulsiveness Scale-11.Methods:(1)According to the Brislin Translation Model,BIS/BAS was translated into Chinese by two experts.Then the Chinese version was translated back to English by two others to compare with the original scale,then revised it.The reliability and validity of the Chinese version of BIS/BAS scales were tested in 1807 college students.(2)A total of 1525 teenagers were investigated with IAT,Online Game Addiction Questionnaire,BIS/BAS scales and BIS-11.Descriptive statistics,t test,variance analysis,Pearson correlation analysis,regression analysis and other statistical methods were used to analyze the data.Results:(1)BIS/BAS scales item analysis showed that 2 and 22 items were deleted;The Chinese version of BIS/BAS scales were consisted of 18 items and 4 fillers;Four factors were extracted by exploratory factor analysis which could explain 49.38%of the total variance.The scales content validity index(S-CVI)was 0.91,and the item content validity index(I-CVI)ranged from 0.82 to 1.0;The result of confirmatory factor analysis(RMSEA=0.06,GFI=0.93,AGFI=0.91,IFI=0.86,CFI=0.86)indicated that the four-factor structure of the BIS/BAS scales was suitable for the Chinese sample.Cronbach's a reliability coefficient for BIS/BAS scales and the four subscales were 0.80,0.70,0.70,0.73 and 0.52 seperately.(2)The prevalence of internet game disorder of teenagers was 11.4%;Regressions analysis showed that impulsiveness and BIS both emerged as significant predictors of IGD among college students(t=3.4.2.8,P<0.01);Both BASR and impulsiveness were significant predictors of IGD among Senior high school students(t=-0.17?2.32,P<0.05);BASf emerged as significant predictors of IGD among Junior school students(t=2.31,P<0.05);Undergraduate and high school students BIS reinforcement sensitivity of IGD was significant difference in different grade(F=3.85?6.86,P<0.05);Conclusion:(1)BIS/BAS contains BIS,BASF,BASR and BASD.Questionnaire analysis shows that the questionnaire is accepted reliability and validity which accord with the requirement of psychometrics,and can be used as a research tool to test the reinforcement sensitivity of the teenagers.(2)Regressions analysis shows that both impulsiveness and BIS emerge as significant predictors of IGD among college students;Both BASR and impulsiveness are significant predictors of IGD among Senior high school students;BASF emerge as significant predictors of IGD among Junior school students;Undergraduate and high school students reinforcement sensitivity of IGD is no significant difference in gender,but BIS is significant difference in different grade.
