FII describes a spectrum of behaviours.
Fabrication
This is the invention of symptoms or signs in the child. The caregiver provides a false story to health professionals. Harm comes to the child through unnecessary interventions, e.g. invasive tests, medication, surgery [1]
Verbal fabrication with supporting evidence
This occurs when verbal fabrications are accompanied by false specimens and/or documents, e.g. manufactured kidney stones, falsified seizure records [1].
Induction of illness
Deliberate causation of signs or symptoms in the child by the caregiver. Causes direct harm to the child:
Obstetric fabrication or induction
This occurs when a pregnant woman falsely describes or induces problems with her pregnancy. This may result in premature delivery, loss of fetus or other harm.
FII co-existing with chronic illness
Co-existing chronic illness is present in many cases of FII [4]. This may make FII more difficult to identify [3].
