Background: Factitious Disorder Imposed on Another (FDIA), previously known as Munchausen Syndrome by Proxy is a rare and severe form of child maltreatment in which a caregiver, predominantly the mother, intentionally fabricates or induces illness in a child to gain attention, validation or control. FDIA is predominantly considered a psychiatric disorder, ignoring the criminal aspect of the abuse with the result perpetrators frequently escape legal accountability. The objectives of this study are to call to attention to the importance of FDIA as a crime, explore how a crime script analysis can be applied to FDIA crimes, and examining the consequences of the failure to consider FDIA a crime. Method: Using a crime script approach, 45 FDIA-C cases were analysed to map the sequence of perpetrator behaviour. Behaviour was classified into six sequential scenes: Preparation, Hospital Admission, Worsening of Symptoms, Post-conditions, Exit, and Aftermath. A dataset with 19 variables mapped to the specified scenes was abstracted from 45 case reports. Results: By mapping and comparing case reports analysis revealed recurring behavioural patterns, including symptom fabrication, manipulation of medical staff, and continued abuse during hospitalization. Conclusion: The study documented that it is feasible to apply a CSA to FDIA crimes, and doing so helped revealed numerous insights and potentially useful interventions that can help improve early detection and limit continued abuse by perpetrators of their children. The study documented very limited legal accountability of FDIA perpetrators, even when they have confessed, suggesting a need for greater emphasis on the criminal nature of FDIA. For this reason, the study coined the term FDIA crime, in the hope that this will be a first step towards greater recognition of FDIA as more than a psychiatric disorder.
