Validity and reliability study of the internet addiction test

This study aimed to identify the construct validity and internal reliability coefficients of the “Internet Addiction Test”, which developed by Young to determine how children perceive themselves about internet addiction. Sample for the adoption study was composed of children ages between 12 and 17 living in the city of Tokat/Turkey (N=480). For the adopted scale, reliability coefficient Cronbach alpha was calculated as 0.90 and Spearman Brown value was calculated as 0.86. Exploratory factor analysis was used to confirm the construct validity; and confirmatory factor analysis used to determine whether the factor model was correct. As a result of this analysis, it was determined that 20 items were grouped under 4 factors. Cronbach α, internal consistency coefficient for the first factor was 0.91; second factor was 0.87; third factor was 0.89; fourth factor was 0.90; and for the whole scale was 0.90. Spearman Brown value for the scale was 0.86. Guttmann Split-Half value for the scale was 0.85. These calculated coefficients were all in the acceptable range, and these suggested that the test and the each factor had internal reliability. Validity and reliability analysis were reviewed about the adoption of Internet Addiction Test and it was concluded that the results that were found was in the acceptable ranges.
