Abstract: | The purpose of this paper is to explore the reasons for unintended placement disruptions in foster care. Based on a semistructured survey, the paper presents the views of 132 Norwegian foster parents who have experienced placement disruption between 2013 and 2015. Foster parents rated several relevant causes of placement disruption: the child's behaviour, the need for care, concern for the well‐being of their biological children, and lack of support from the Child Welfare Service (CWS). Although the child's behaviour was the cause most frequently reported in the quantitative data, CWS‐related factors such as poor collaboration, not being valued and listened to, insufficient support and follow‐up, and a mismatch between the child's needs and the foster carers' capacity were reported most frequently in the qualitative data. Placement disruption appears to be caused by the sum and interaction of several coexisting causes. It may not be the child's behaviour per se but rather the combination of challenging behaviour, concern for one's biological children, and insufficient support from CWS that lead to disruption. Good collaboration with the CWS in the form of respect, recognition, support, and follow‐up appears to be of the utmost importance in reducing the risk of placement disruption. |
