Abstract

OBJECTIVES
The Young's internet addiction test (IAT) is used worldwide, and the psychometric properties of IAT have been documented in other countries. The aim of this study was to evaluate and validate the factors and structure of the IAT as applied to Korean college students.
METHODS
Data was collected from students (n=2216) at Kongju National University via an online survey system. The factor structures of the IAT were assessed using exploratory and confirmatory factor analysis.
RESULTS
The IAT produced acceptable internal consistency and reliability (Cronbach alpha=0.921). We discovered that the two-factor structure of the IAT produced acceptable psychometric properties. Factor 1 consisted of the aspiration and obsession to achieve orientation in cyberspace, Factor 2 consists of loss of control, withdrawal, and neglect of social interaction and duties. These findings were inconsistent with those of previous studies. There were no significant gender differences observed in internet addiction rates.
CONCLUSION
IAT is a reliable scale which identifies two internet addiction factors in Korean college students. This scale could be useful to quantitatively evaluate internet addiction.
