This study aimed to develop a self-rating scale on smartphone behavioral addiction, using which university students can evaluate how smartphones should be used. We surveyed addiction scale created by researchers for students using smartphone who were enrolled in a university in the metropolitan area. A total of 587 valid responses were obtained. We surveyed 243 males and 344 females. Using exploratory factor analysis, the following 5 factors were identified from 20 items. “self-dominance”, “erosion of life”, “withdrawal symptoms”, “exacerbation of addiction”, and “can’t control phone”. In covariance structure analysis, GFI (Goodness of Fit Index) =0.931, AGFI (Adjusted GFI) =0.909, CFI (Comparative Fit Index) =0.932, and RMSEA (Root Mean Square Error of Approximation) =0.052. A significant correlation was observed between smartphone utilization time. This scale showed reliability and validity.
