Abstract: The purpose of this study was to explore the association between preschool children's attachment relationships with adults and their peer relationships.Seventy-eight preschoolers (38 girls,40 boys),their mothers(n=78)and their preschool teachers (n=12) participated in the study.The average age of the children was four years and ten months.The measure used to assess attachment quality was the Waters and Deane's Attachment Q-set.The measures used to assess peer relationship were peer sociometric interviews and the teacher's rating.Research results indicated a strong correlation betweenyoung children's maternal as well as teacher-child attachment relationships and their peer relationships at preschool.Children with secure attachment relationskip with adults tend to be less aggressive,they like to help other children,and are more popular among peers.
