Outline of Final Research Achievements

Persons with autism spectrum disorder (ASD) and/or attention deficit/hyperactivity disorder (ADHD) have a tendency to show pathological internet use because of his/her diagnostic characteristics. Pathological internet use was said to be related with callous-unemotional traits, which can directly predict antisocial behaviors; hence, I have explored a hypothetical model including, characteristics of ASD/ADHD, CU traits and pathological internet use.
