Purpose: To explore the relationship between self-control, rejection sensitivity, loneliness, and problematic internet use in college students.
Patients and Methods: A total of 725 college students were investigated using Self-control Scale, Rejection Sensitivity Questionnaire, Loneliness Scale, and Internet Addiction Scale.
Results: ① Correlation analysis showed that self-control was negatively related to rejection sensitivity, loneliness, and problematic internet use; rejection sensitivity was positively related to loneliness and problematic internet use; loneliness was positively related to problematic internet use. ② Chain mediating effect analysis showed that self-control can not only affect problematic internet use in college students, but also through three indirect paths, as follows: the mediating role of rejection sensitivity and loneliness, the chain mediating roles of rejection sensitivity and loneliness, and the mediating effect size, accounting for 9.76%, 20.73%, and 4.88% of the total effect, respectively.
Conclusion: Rejection sensitivity and loneliness played a chain mediating role in the relationship between self-control and problematic internet use in college students.
