The purpose of this study is to evaluate the psychometric properties of the Egyptian translation of SAS-SV for adolescents. The SAS-SV (Kwon et al., 2013) is a 10 items with a 6-point Likert scale from 1 = strongly disagree, 6 = strongly agree. Total scores typically range from 10-60, with higher score indicating Problematic Smartphone Usage. Item analysis of Smartphone Addiction Scale for the participant students is shown in Table 1. The internal consistency of the scale was adequate. Cronbach's alpha ranged from 0.745 to 0.893 to all items. Reliability coefficient for all the scale was high (alpha = 0.904). Content validity was confirmed by statistically significant differences between heavy and light users (p <0.001). The use of this instrument can be used conveniently in the screening process to determine those who are likely to be labeled " Smartphone Addicted" in Egypt.
