Abstract
Adoption breakdown has attracted an increasing amount of attention over recent years, and studies coincide in stating that the mean age at which this phenomenon occurs is early adolescence. Nevertheless, the specific factors which influence adoption breakdown, have never been empirically explored. The aim of this article is therefore to analyse these factors by comparing cases of adoption breakdown which occurred prior to the onset of adolescence with those occurring after the beginning of this developmental stage. The study explores 69 cases of adoption breakdown occurring over the course of a decade in one Spanish region, taking into consideration variables related to the adopted children, the adoptive parents, the parent–child relationship, and the professional support services provided to these families. The results reveal a clear difference in the profile of breakdowns occurring before and after the onset of adolescence and identify a series of factors which seem to have a stronger influence in each group, such as violence, timing of problems, and unrealistic expectations regarding the child. These findings have important implications for professional adoption services, such us the importance of early identification of difficulties and the provision of support during adolescence.
