- Abstract
Background: The prevalence of problematic internet use (PIU) has been on the rise, with an estimated rate of 20% among Southeast Asian. The resting-state functional connectivity (rsFC) of a triple-network model has been described inconsistently in PIU adolescents. Methods: A total of 30 subjects with PIU and 30 healthy Indonesian adolescents were recruited. IAT was used to determine the presence of PIU. Focusing on the DMN, SN, and CEN, we compared rsFC values of the fMRI between PIU and control groups. Additionally, associations with personality traits, utilizing Temperament and Character Inventory, and affective/behavioral problems, using the Strength and Difficulties Questionnaire, were explored. Results: Higher rsFC values of the left lateral prefrontal cortex (LPFC(L)) with the left anterior insula were observed for PIU than in control. While rsFCs of the LPFC(L) with the medial PFC (MPFC) as well as with the right lateral parietal cortex were lower for PIU. Among these significant group differences, the rsFC between the LPFC(L) and MPFC was mediated by emotional symptoms (standardized ß=-0.12, 95% CI -0.29,-0.0052). The dysfunctional attention switching and incentive salience regulated by the SN was implicated as a possible neural correlate of PIU, potentially explaining the relationship between emotional dysregulation and PIU in adolescents. Conclusion: Increased connectivity between the nodes of the CEN-SN and decreased connectivity among the nodes of the CEN-DMN were found among PIU adolescents. These findings suggest an underlying neural mechanisms of poor cognitive and emotional response inhibition, which is a potential intervention target for PIU.
