Kardeş doğumu ile büyük çocuğun dışsallaştırma davranışları arasındaki ilişki

The research indicates that there is an association between the birth of a sibling and externalizing behaviors of the older children. In this association, two aspects of the parent-child relationship: (i) the parental resources that are provided to the older child, (ii) the characteristics of the real time interactions between the mother and the older child, and maternal depression might play a role. In the current study, this association was tested. The data from the Study of Early Childhood Developmental Ecologies in Turkey (ECDET) was used. In Study 1, quantitative data was used (N = 560) while in Study 2 qualitative data was used (N = 101). Current research investigated that whether there was association between (a) sibling birth and parental resources, (b) sibling birth and real time interactions, (c) sibling birth and maternal depression, and (d) sibling birth and externalizing behaviors of the older children. Also, parental resources and real time interactions were taken as possible mediators for the association of sibling birth with externalizing behaviors of the older children. Last, the association of sibling birth with parental resources and with children's externalizing behaviors was investigated for participants of Study 1 who were at high risk for being influenced by sibling birth. Results showed that (1) there was an association of sibling birth with developmental resources; (2) sibling birth predicted mother behaviors and child behaviors during real time interactions at post-birth interview; (3) variety of experiences was found as a mediator of the association of the sibling birth with externalizing behaviors of older children; (4) in all high risk subgroups, externalizing behaviors of older children were predicted by harsh discipline at post-birth interview.
