We conducted a hierarchical multiple regression analysis to examine the effects of smartphone use for information seeking, entertainment seeking, gaming, mobile SNS, and mobile instant messenger on smartphone dependence after controlling smartphone usage frequency, and smartphone usage time. As a result of the analysis, the frequency of smartphone use of weekday (p<0.001) and weekend (p<0.001) was related to the dependence on smartphones. In addition, the amount of smartphone use for information seeking (p<0.01), entertainment seeking (p<0.05), and gaming (p<0.001) were associated with the dependence of smartphone.
