 note = {The purposes of this study were 1) to construct Internet Addiction Test (IAT) short version to estimate the internet addiction of primary school children, and 2) to describe the change in the scale value with grade advancing from primary to high school, using item response theory (IRT). The 20 scale items of IAT by K. Young were applied to junior and high school students (n = 1,287). The IRT parameters of 20 items of IAT were estimated by the graded response model of IRT using junior and high school students’ response. The cut-off values of internet addiction for IAT short version to determine internet addiction were calculated. The latent trait of internet addiction by IRT from primary to high school students were analyzed by the two-way ANOVA. The main effects of grades (p<0.001) and the interaction of grades*sex were significant (p<0.001). The latent trait of internet addiction showed a significant rising trend as grade advanced., text, application/pdf},
