Final answer:
Munchausen syndrome by proxy (MBPS) is a complex psychological disorder where a caregiver induces illness in another to gain attention. Its causes are related to psychological issues and a need for attention or control.
Step-by-step explanation:
The etiology of Munchausen syndrome by proxy (MBPS) is complex and not entirely understood. It is a psychological disorder wherein a caregiver, usually a parent, fabricates, exaggerates, or induces illness in a person under their care, typically a child, to gain attention or sympathy.
The motives behind MBPS are thought to be related to a desire for the caregiver to assume a sick role by proxy and involve a need for attention, a form of control or abuse of power, and pre-existing psychological problems. Treatment often requires both psychological support and legal intervention to ensure the safety of the victim.
