The study was carried out with 559 Turkish university students. The research data were analyzed by multiple regression analysis. The findings indicated that loneliness, depression, and computer self-efficacy were significant predictors of problematic Internet use. Loneliness was found as the most important predictive variable. Depression predicted problematic Internet use on the second rank, and computer self-efficacy on the third rank.
