Abstract

The purpose of this paper is to upgrade the internet addiction tendency scale for high-school students, utilizing visual analog scale (VAS). High-school students (n=355(male=303, female=52)) answered 7 items about “Questionnaires relating to the sending and reception of messages on the internet” and 10items about “Questionnaires relating to the participation attitude to the internet”. The important results of the analysis are as follows: (1) It is showed that there are similar distributions between Q1.1 (I get worried if I receive no response to my message) and Q1.2 (I want to check my cell-phone many times when I send my message). (2) It is showed that there are similar distributions between Q2.5 (Although after midnight, I would continue to use the internet for 1 hour or more) and Q2.6 (My sleep time becomes shorter if my utilization time for the internet is longer). (3) The number of clusters in the “Questionnaires relating to the sending and reception of messages on the internet” is defined as 3. (4) The number of clusters in the “Questionnaires relating to the participation attitude to the internet” is as defined as 2.
