Abstract: Objective To explore the interventione effect of the multi-channel electroencephalogram biological feedback on the teenagers of Intemet addiction,and to provide reference for conducting intervention among adolescents with Internet addiction.Methods Totally fifty cases of Internet addiction teenagers were randomly divided into two groups.Totally 25 cases were taken multi-channel biofeedback treatment;else teenagers were taken traditional psychological behavior intervention.Diagnosis scale of Young's Internet Addiction Test (IAT) and Self-evaluation of the Anxiety Scale(SAS) were used to evaluate the curative effect of the two groups.All subjects filled in these two scales before and after the treatment.Results IAT score of test group decreased from 72.78 to 58.67 (t =4.267,P< 0.01) after 12 weeks treatment,SAS score of test group decreased from 36.84 to 30.35(t =3.689,P=0.001);IAT score of control group decreased from 72.47 to 65.05(t =2.181,P=0.039),SAS score of control group decreased from 37.07 to 33.23(t =2.216,P=0.036).However,both the scores of two scales of the test group were significantly lower than the scores of the control group (t =2.092,2.101,P<0.05).The effective rate of test group(32%) was significantly higher than that of control group(8%) (x2 =4.500,P=0.034).Conclusion The curative effect of multi-channel biofeedback treatment is more effective than traditional psychological behavior intervention,but it cannot completely correct Internet addiction behavior in 12 weeks.
