This study was conducted to investigate the relationship of attachment to mother and teacher to the social competence of elementary school children. Subjects were three-hundred seventy-one 5th and 6th graders. Participants completed two subscales(mother and teacher) of the Inventory of Parent and Peer Attachment - Revised for Children and Social Competence Scale. Collected data were analyzed using MANOVA. Research findings of this study can be summarized as follows: First, there were statistically significant differences in all the sub-factors(namely, sociability, interpersonal adjustment, social participation, initiative and popularity) of social competence according to attachment to teacher. Second, there were statistically significant differences in social competence according to four multiple attachment type which is classified by the level of attachment to mother and teacher. More specifically, children who are more attached to both mother and(or) teacher showed higher social competence than those who are less attached to both mother and teacher. It was concluded that although attachment to mother is a little more important, attachment to teacher is also important in developing social competence of elementary school children. The implications of this study for teacher were discussed and recommendations for future research based upon the limitations of this study were made.
