Objectives: This study aimed to identify whether internet addiction is made up of subtypes that identified heterogeneous feature.
Methods: A total of 222 college students were given the following : Behavioral performance test (Iowa Gambling Task, Balloon Analogue Risk Task), and Psychological rating scales (Internet Addiction Test, Adult Attention-Deficit Hyperactivity Disorder Scale, Barratt Impulsiveness Scale, Wender-Utah Rating Scale, Domain Specific Risk-Taking Scale, Beck Depression Inventory, Beck Anxiety Inventory, Resilience Scale, Paranoia Scale, State and Trait Anxiety Inventory, Self Efficacy Scale, Temperament and Character Inventory). Participants were classified into 3 groups (2 excessive internet use groups, 1 normal group) by the discriminant analysis. We also investigated the difference in the 3 groups.
Results: Higher impulsivity, ADHD symptoms and level of risk-taking are associated with excessive internet use groups. There were significant differences between the two excessive internet use groups. One group had higher levels of risktaking, resilience, self-efficacy, whereas the other group had higher depression, anxiety, paranoia, harm avoidance, lower self efficacy, resilience, and persistence.
Conclusion: In our study, excessive internet users were classified into two different groups. These results suggest the possibility that internet addiction may be classified into subtypes. However, this study has many limitations ; thus, we modified the study in order to obtain meaningful results as needed.
