Abstract
Background
Patients with internet gaming disorder (IGD) suffer from an imbalance of over-integrated and weakly dissociated functional brain networks. Approach bias modification training (ApBMt) has been used to correct patients’ automatic approach biases to addictive stimuli; however, research exploring changes in brain network topology is limited.
Methods
Seventy subjects were randomly assigned to the approach-avoidance task (AAT) group or the sham-AAT group, and 57 subjects (AAT, 30; sham-AAT, 27) completed the entire procedure, which included pretests, AAT/sham-AAT interventions, and posttests. Behavioral and resting-state fMRI data were collected before and after the tests. This study aimed to investigate the effects of ApBMt on topological changes in resting functional brain networks in patients with IGD and explore the relationship between these network changes and behavioral indicators of addiction severity.
Results
Repeated-measures ANOVA of the behavioral data showed that the AAT group had significant score reductions after ApBMt. Imaging data revealed significant decreases in brain network over-integration and increases in segregation of the fronto-parietal network (FPN) and the cingulo-opercular network (CON). Additionally, a positive correlation was found between the post-pre difference in DSM-5 scores and the post-pre difference in nodal efficiency (Ne) in the anterior prefrontal cortex (aPFC).
Conclusions
The findings of this study demonstrate that ApBMt effectively reduces the severity of IGD, along with associated changes in brain network topology, such as enhanced segregation and decreased over-integration. However, it is important to highlight that the neurobiological changes observed are correlated with the reduction in IGD severity, but causality cannot be established. Further research is necessary to better understand the clinical potential of ApBMt in treating IGD, either as a stand-alone intervention or in combination with other therapeutic approaches.
期刊介绍:
Addictive Behaviors is an international peer-reviewed journal publishing high quality human research on addictive behaviors and disorders since 1975. The journal accepts submissions of full-length papers and short communications on substance-related addictions such as the abuse of alcohol, drugs and nicotine, and behavioral addictions involving gambling and technology. We primarily publish behavioral and psychosocial research but our articles span the fields of psychology, sociology, psychiatry, epidemiology, social policy, medicine, pharmacology and neuroscience. While theoretical orientations are diverse, the emphasis of the journal is primarily empirical. That is, sound experimental design combined with valid, reliable assessment and evaluation procedures are a requisite for acceptance. However, innovative and empirically oriented case studies that might encourage new lines of inquiry are accepted as well. Studies that clearly contribute to current knowledge of etiology, prevention, social policy or treatment are given priority. Scholarly commentaries on topical issues, systematic reviews, and mini reviews are encouraged. We especially welcome multimedia papers that incorporate video or audio components to better display methodology or findings.
Studies can also be submitted to Addictive Behaviors? companion title, the open access journal Addictive Behaviors Reports, which has a particular interest in ''non-traditional'', innovative and empirically-oriented research such as negative/null data papers, replication studies, case reports on novel treatments, and cross-cultural research.
