Munchausen Syndrome by Proxy (the fabrication of illness by a mother i
n her child) is often a serious form of child abuse that has been reco
gnized increasingly over recent years. Approximately one-half of the m
others in this study had either smothered or poisoned their child as p
art of their fabrications. Lifetime psychiatric histories are reported
for 47 of the mothers. Thirty-four had a history of a Factitious or S
omatoform disorder, 26 a history of self harm, and 10 of alcohol or dr
ug misuse. Nine mothers had a forensic history independent of convicti
ons related to child abuse. Nineteen of these mothers were interviewed
from 1-15 years after the original fabrications. The most notable psy
chopathology was the presence of a personality disorder in 17 of the m
others, which were not predominantly Histrionic and Borderline types.
Most subjects, however, met the criteria for more than one category of
personality disorder.
