The relationship between personality traits, psychopathological symptoms, and problematic internet use: a complex mediation model

Background: There are many empirical studies that demonstrate the associations between problematic internet use, psychopathological symptoms, and personality traits. However, complex models are scarce. Objective: The aim of this study was to build and test a mediation model based on problematic internet use, psychopathological symptoms, and personality traits. Methods: Data were collected from a medical addiction center (43 internet addicts) and internet cafés (222 customers) in Beijing (Mean age = 22.45 years, SD = 4.96; 90.2% males). Path analysis was applied to test the mediation models using structural equation modelling. Results: Based on the preliminary analyses (correlations and linear regression), two different models were built. In the first model, low conscientiousness and depression had a direct significant influence on problematic internet use. The indirect effect of conscientiousness – via depression – was non-significant. Emotional stability only affected problematic internet use indirectly, via depressive symptoms. In the second model, low conscientiousness also had a direct influence on problematic internet use, while the indirect path via the Global Severity Index was again non-significant. Emotional stability impacted problematic internet use indirectly via the Global Severity Index, while it had no direct effect on it, as in the first model. Conclusion: Personality traits (i.e., conscientiousness as a protective factor and neuroticism as a risk factor) play a significant role in problematic internet use, both directly and indirectly (via distress level)
