Introduction: As the world's fastest growing "addiction", Internet addiction is still controversial. The present study aimed to examine the potential personality predictors of Internet addicts.
Methods: Eight hundred and sixty-eight students were tested using the Eysenck Personality Questionnaire after they had just entered university. Two years later, 49 were found to be addicted to the Internet as defined by high Internet addiction test scores. Comparisons of means and logistic regression analysis were used to explore their relationship.
Results: Students addicted to the Internet showed higher Neuroticism/Stability scores, higher Psychoticism/Socialization scores, and lower Lie scores than their normal peers before their addiction. Regression results showed that Internet addiction was accounted by three independent variables: Neuroticism/Stability, Psychoticism/Socialization, and Lie.
Conclusion: These results suggest that the risk personality traits of Internet addiction include neuroticism, psychoticism, and immaturity.
Keywords: Internet addiction; Iongitudinal study; personality.
