Abstract
Most Dutch foster children live permanently in foster families. It is often assumed that foster children have ambivalent loyalties and attachments to their birth parents and foster parents and are torn between the two. In this study 59 children between 10 and 18 years placed in long term foster care completed standardized questionnaires on the relationship with their parents respectively foster parents and their wellbeing. Results show that, on average, foster children have positive feelings of loyalty and attachment towards both their foster parents and biological parents. However, their wellbeing appeared mainly related with stronger attachment representations towards their foster parents. This study found no indications for a competing position of biological parents and foster parents from the perspective of the child. Nevertheless, foster children who see their foster and biological parents as more vulnerable or experience stronger normative boundaries, feel worse compared to children who experience this feelings less.
