Differing approaches to the identification of Munchausen by proxy syndrome (MBPS): a case of professional training or role of experiental exposure

Abstract

Much recent research recognises that a multidisciplinary team approach is best to manage Munchausen by Proxy Syndrome (MBPS), an extreme manifestation of factitious disorder by proxy (FDBP). Generally described as fabricating illness symptoms in a child to serve the adult caretaker's attention seeking needs, identification of the disorder remains problematic. Various relevant professionals differ in their emphasis and vary in their knowledge of the condition which in turn can inhibit collaborative investigation and intervention. Reasons for these difficulties are described together with a rationale for better interagency co-operation, not least because the outcome in some cases is the death of the child. The present paper discusses the implications of professional training in identification of MBPS and the value of previous exposure to cases in increasing likelihood of detection. An empirical study is described that presents working models used by different professionals to identify cases of MBPS (n=12). Analysis of qualitative interview material by means of a multidimensional scaling procedure revealed no clear grouping in terms of occupational specialism, rather commonalities of approach appeared related to previous experience with MBPS. The range of salient factors elicited was used to devise a parsimonious screening checklist intended for use by different professional groups. Finally, future research in terms of investigating psychometric profiles of MBPS child abusers and demonstrating the utility of the checklist for use by multidisciplinary teams in early detection and subsequent management of MBPS is discussed.
