The mediating role of inhibitory control and the moderating role of family support between anxiety and Internet addiction in Chinese adolescents

Abstract

Objective

While some studies have explored the influencing factors of adolescent internet addiction, the risk factors and protective factors still require further discussion. This study aims to examine the mediating role of inhibitory control between anxiety and internet addiction among Chinese adolescents, as well as the moderating role of family support in the relationship between anxiety and inhibitory control.

Methods

A cross-sectional study was conducted through convenience sampling from February to March 2024 in seven schools across five provinces in China. A total of 1677 participants (697 males and 980 females) with an average age of 15.86 ± 0.74 years were included in the study. Self-reported data on internet addiction, anxiety, inhibitory control, and family support were collected, followed by correlation analysis and moderated mediation model testing.

Results

After controlling for participants' gender and age, the study found that anxiety could significantly predict adolescent internet addiction directly (β = 0.429, p < 0.001). When inhibitory control was introduced as a mediating variable, the predictive effect of anxiety on adolescent internet addiction remained significant (β = 0.317, p < 0.001). Additionally, family support alleviated the relationship between anxiety and adolescents' inhibitory control (β = −0.057, p < 0.01).

Conclusion

Anxiety can predict adolescent internet addiction through inhibitory control, while family support can moderate the predictive relationship between anxiety and adolescents' inhibitory control. It is recommended that guardians pay attention to adolescents' negative emotions, provide adequate support, guide emotional regulation, and prevent the occurrence of internet addiction.
