The IAT asks a straightforward question in 20 different ways: how much is your internet use getting in the way of daily life? Work, relationships, sleep -- the usual suspects. Dr. Kimberly Young adapted it from the pathological gambling criteria back in the 1990s, and it is still one of the more common screening tools for this.
Scoring
- 20-30: Normal user. Internet use is not causing significant problems.
- 31-49: Mild addiction. Some online behavior is starting to cross the line.
- 50-79: Moderate addiction. Internet use is noticeably interfering with daily life.
- 80-100: Severe addiction. This needs attention.
Reliability and validity
Internal consistency runs a = .90-.93, and test-retest reliability is solid. Factor analysis typically pulls out six dimensions: salience, excessive use, neglect work, anticipation, lack of control, and neglect social life.
