Final answer:
FDIA is characterized by fabricated or induced illness by someone in someone else they care for, per the DSM-5. Diagnosis involves consideration of both the individual and the victim's medical and psychological background. A multidisciplinary approach is commonly needed for intervention and confirmation of FDIA.
Step-by-step explanation:
The DSM-5 criteria for Factitious disorder imposed on another (FDIA), previously known as Munchausen syndrome by proxy, are not explicitly provided in the resources above. However, based on the DSM-5, the term "Factitious Disorder Imposed on Another" describes a condition wherein one individual, the perpetrator, fabricates or induces physical or psychological symptoms in another person, typically someone under their care, without any external incentives for doing so.
The diagnosis requires the following: falsification of physical or psychological signs or symptoms, or induction of injury or disease, in another, associated with identified deception. The individual presents another individual (victim) to others as ill, impaired, or injured. The deceptive behavior is evident even in the absence of obvious external rewards. The behavior is not better explained by another mental disorder, such as delusional disorder or another psychotic disorder.
To accurately diagnose FDIA, it is crucial that a thorough evaluation is conducted, including the medical history of the person under care and the caregiver's behavior. If FDIA is suspected based on the DSM-5, a multidisciplinary approach involving medical, psychological, and sometimes legal intervention is usually necessary.
DSM-5 defines FDIA as falsification of illness in another without external incentives, requiring multidisciplinary diagnostic and intervention approaches.
