Addiction to the internet is one such problem and identified to exist among the general population and students in other countries. The most common tool used to measure internet addiction is Young's internet addiction test. The phenomena of internet addiction has not been scientifically studied in Sri Lanka according to our knowledge.

Once validation of the scale was established the translated scale was used on a sample of 2800 students to assess presence of internet addiction.

Result

Internet addiction was identified among the study population. 8% of the entire study sample and 12.6% among those using the internet showed features of internet addiction. The majority of cases of internet addiction identified were mild 8.2% followed by moderate internet addiction in 3.6% and only 0.9 % having severe internet addiction. There were no significant demographic or internet use related features identified among those with internet users and those not addicted to the internet.

It also identified that there are students in Sri Lanka who are addicted to the internet.
