Factitious Illness by Proxy: Understanding Underlying Psychological Processes and Motivations

Children are put at risk of emotional and physical harm when parents seek unnecessary medical care. Understanding why parents seek medical interventions that create risk for their children requires us to consider how past experiences, and the mental representations of these experiences influence current behaviour. Past experiences of danger affect how parents interpret 'dangerous' situations in the present and how they organise protection of their child. This article demonstrates how the notion of mental representations (that dispose parents to act in particular ways) can assist in engaging, assessing and treating parents who display factitious illness by proxy behaviour. When classified using the Dynamic-Maturational Method, the Adult Attachment Interview (AAI) allows both assessment of implicit and explicit representations and also understanding of the developmental process through which parents have learnt to attribute meaning to information and to organise their behaviour. In this case study, psychosocial assessment of the family included an AN with each parent. The use of this assessment tool both aided the therapy team in the process of case formulation and intervention planning, and had therapeutic value in and of itself. We argue that treatment is more likely to be effective if the parents and professionals have a shared understanding of the parents' intentions and the developmental process that led to unsafe behaviour, which requires change.
