This study looked at whether insecure attachment style among Chinese university students categorized as "Gen Z" is predictive of various types of Internet addiction using an online survey. Using simple random sampling, 796 Chinese university students (581 valid questionnaires) were chosen as participants. The chi-square test results showed a strong correlation between insecure attachment style and addiction to online gaming and relationships, but not with addiction to online information. Online gaming and online relationship addiction were positively connected with anxious and fearful avoidant attachment, according to binary logistic regression studies, but dismissive avoidant attachment did not demonstrate any significant correlation. These results imply that online relationships and game addiction are partially predicted by an insecure attachment type.
