title: The relationship between personality, defense styles, internet addiction disorder, and psychopathology in college students.
abstract: The purpose of this study is to assess any underlying links between personality, defense styles, Internet addiction disorder (IAD), and psychopathology in a college student sample. This is a cross-sectional study of fourth-year Greek Medical students who responded in a comprehensive test battery, which included validated questionnaires on IAD, personality traits, patterns of psychological defense styles, and psychopathology symptoms. A path model that was tested using Partial Least Squares (PLS) methodology showed that the defense styles employed by the students and certain personality traits (Impulsivity, Sensation Seeking, Neuroticism/Anxiety, and Aggression-Hostility) contributed to the prediction of variability in IAD, with IAD in turn predicting variability in overt psychopathology.
