It is believed that parental behaviours play a critical role in the development of self-concept. Recent research studies have shown that parents' romantic attachments affect both their parental behaviours and their children's behaviours. The purpose of this research is to examine predictive levels of parents' level of dimensions of attachment (attachment anxiety and attachment avoidance) together with their participation in the development of their children's self-concept. In this research, which examines parents' level of interest towards their children, The Scale of the Mother's and Father's level of Interest towards their Children were used to examine the level of the children's self-concept through the Demoulin Self-Concept Developmental Scale for Children in order to obtain the parents' dimensions of attachment in the Experiences in Close Relationships-Revised II Scale. It was seen that both types of dimensions of attachment on the mothers' and on the fathers' affected the children's self-concept negatively.
