摘要:This research addressed the issue of how mothers` representations of attachment are transmitted to children,focusing on post-infancy attachment and on maternal stress as a mediator between mother`s attachment style and child attachment security. Fifty-three mother-child dyads participated in a lab visit when the children were 30 months (T1) and 49 months (T2) of age. The Attachment Style Questionnaire and the Parental Stress Inventory were used to measure mothers` characteristics;the Separation-Reunion procedure and classification at T1 and the Attachment Q-set at T2 were used to measure children`s attachment security. The models were analyzed by Analysis of Moment Structure Equation. Results confirmed evidence that no direct pathway exists between maternal attachment style and child attachment security : at T1 child attachment security formation was related to maternal stress,but there was no such relationship at T2.
