| College students are the main group of Internet users,and according to many studies,Internet addiction is very common among this group,and college students show a higher rate of addiction.Internet addiction can lead to impaired psychological,physiological and social functioning;therefore,it is important to investigate the clinical value of intervention methods for Internet addiction among college students.Studies have shown that individuals with Internet addiction have poorer attentional performance and lower attentional network functioning than non-Internet addicts.Current research on interventions for Internet addicts is based on cognitive behavioral therapy,positive thinking,and pharmacotherapy.However,studies have shown that interventions with "future-oriented" Focused Solution Brief Therapy(SFBT)for college students with Internet addiction can be effective in improving behavioral performance related to Internet addiction symptoms.Therefore,the present study uses SFBT as the theoretical core and group counseling as the intervention method to explore the behavioral manifestations,attentional network functions,and related neural mechanisms of Internet addiction among Internet-addicted college students.The study contains two parts,Study 1 explores the differences in Internet addiction-related behavioral performance and attentional network function of Internet addicted college students before and after the intervention,and Study 2 explores the differences in attentional network neural activity of Internet addicted college students before and after the intervention.Study 1 explored whether there was an improvement in Internet addiction behavioral performance and attentional network functioning among Internet-addicted college students after the Internet addiction intervention through a SFBT group counseling intervention.The intervention of this study were conducted in two phases,and before the start of the first phase of group counseling activities,32 Internet-addicted college students were screened by the Fan Fu-Min and Bai Yu Internet Addiction Scale(CIAS-R)and structured interviews at Southwestern University,and due to the withdrawal of three subjects,the final randomized group was 14 in the experimental group(6 males,8 females,with an average age of 19.50 ± 1.22)and 15 in the control group(5 males,10 females,with an average age of 19.73±1.34).During the pretest phase,the experimental and control groups completed the CIAS-R scale and the Attention Network test,followed by a month and a half(5 sessions)of group counseling activities for the experimental group and no intervention for the control group.Immediately after the group counseling sessions,the experimental and control groups completed the CIAS-R scale and the ANT test.One week later,the second phase of group counseling activities began,with the same content setting as the first phase of group counseling.The members of the second phase of group counseling were from the control group in the first phase of group counseling,and because three subjects withdrew,12 subjects(4 males and 8 females,with an average age of 19.33±0.99)eventually participated in the second phase of group counseling throughout.The results revealed that(1)the total CIAS-R scores and the scores of the four sub-dimensions were significantly lower in the experimental group than in the control group after the intervention in the first phase of the group assistance.(2)In the first phase of group assistance,the response time of the attentional executive network was significantly lower in the experimental group than in the control group after the intervention,that is,the executive network function was significantly higher in the experimental group than in the control group after the intervention,and there were no significant differences in the attentional vigilance network and the attentional orientation network between the two groups of subjects before and after the intervention.(3)The total CIAS-R scores as well as the scores of the four sub-dimensions were significantly lower in the 12 subjects after the intervention than before the intervention in the second phase of the group supplementation.(4)In the second period of group facilitation,the reaction time of the attentional executive network of the 12 subjects after the intervention was significantly lower than that before the intervention,i.e.,the executive function of the 12 subjects after the intervention was significantly higher than that before the intervention,and there was no significant difference between the attentional vigilance network and the attentional orienting network of the 12 subjects before and after the intervention.(5)The amount of change in total Internet addiction score was significantly and positively correlated with the amount of change in executive network effects.Study 2 further explored whether there was an improvement in attentional network neural activity after the intervention in internet-addicted college students by means of event-related potentials(ERP).The composition of the subjects in this study was the same as in Study 1,and the EEG activity signals of the subjects during the completion of the ANT task were recorded for all three measurements.The results revealed that the P3 component wave amplitude was higher in the experimental group than in the control group after the intervention(p=0.068),and there was no significant difference between the N1 component wave amplitude in the experimental group and the control group after the intervention.That is,the SFBT group-assisted intervention improved the neural activity of individuals’ attentional executive network and enhanced the ability of individuals to allocate attentional resources to processing conflicting and distracting information.Moreover,a correlation analysis between the behavioral results of the attentional network and the ERP results of the experimental group post-test revealed that the executive network effect was significantly and positively correlated with the P3 component wave amplitude in the Pz congruent condition and the CPz congruent condition,i.e.,the worse the behavioral performance of the individuals,the greater the P3 wave amplitude produced in accomplishing congruent goals at the Pz and CPz locations.In summary,this study explored the intervention effects of SFBT group counseling on Internet-addicted college students more comprehensively at the behavioral and neurophysiological levels and found that SFBT group counseling could effectively improve the performance of Internet-addicted college students’ symptoms related to Internet addiction and further enhance attentional executive network functions.This study further enriches the research on the neural basis of attentional networks in Internet-addicted college students,has strong practical reference significance,and provides strong practical value for clinical interventions in Internet addiction. |
