The purpose of this study is to explore the relationship between motives of smartphone use, social relation, and psychological well-being. The correlation analysis shows that the motives of smartphone use were positively related to bonding relations but negatively related to bridging relations. The hierarchical multiple regression analysis finds the associations among motives of smartphone use, social relations, perceived social support, and variables of psychological well-being. The results demonstrate that needs for caring for others were negatively related to loneliness and depression and positively related to self-esteem. However, the communication motives are not a significant predictor to determine self-esteem, loneliness, and depression. In addition, bonding and bridging social relations and social support significantly increase self-esteem and decrease loneliness and depression.
