items of the IAS are calibrated scores ranging from 1 to 5 (given a total score ranging from 20 to 100), with higher scores reflecting a greater tendency toward addiction. Three types of Internet user groups were identified, internet addicts, showing limited symptoms and showing no symptoms, whose scores were higher than 80, between 50-79 and below 50. The internal consistency (Cronbach alpha coefficient) of the Turkish IAS is .90 .
2.2.2. Coopersmith Self-Esteem Scale (CSEC) This scale has two different forms; a long form composed of 58 items and a short form composed of 25 items. In this study, the long form of 58 items has been used. The original scale translated into Turkish by Piúkin (1996). With it, it is possible to obtain scores for 5 subscales. These are: general self-esteem, school and academic self-esteem, family and home self-esteem, and false items. The sum of the scores obtained from the subscales of the inventory, except for the false items; indicate the total self-esteem of the scale. Total score has been taken into account in the reliability and validity calculations of the scale. In different groups, KR-21 scores have been calculated as between .75 and .83. The correlation coefficient between the applications conducted on 51 students with a two-week interval for the repetition reliability of the test has been found as .70.
