Women are the only reported perpetrators of Munchausen syndrome by proxy (MSP), in which a parent knowingly creates or exaggerates physical symptoms in a child. Gender-sensitive family systems theory, theories of women's psychological development, and theory relevant to the intergenerational transmission of child abuse are applied to explain why women are more vulnerable than men to developing MSP. Mothers with MSP sacrifice self-care for other care. By presenting a "sick child" to the medical profession they receive self-care in the form of socially sanctioned other care. Treatment can empower women with MSP by examining their histories of adherence to traditional sex roles, indirect use of power, reliance on male authority, and devaluation of women. A sociocultural perspective helps to avoid mother blaming and encourages movement beyond narrow sex roles.Munchausen syndrome by proxy (MSP) has received increased attention in the pediatric literature, as it is very disturbing to health professionals and extremely diificult to detect. The syndrome was first described by Money and Werlwas (1976) and later by Meadow (1977) as the downward extension of the adult Munchausen syndrome. Adult Munchausen syndrome is characterized by an adult's chronic and relentless pursuit of medical treatment, involving some combination of consciously self-inflicted injury and falsely reported symptomatology (Asher, 1951;Spiro, 1968). In MSP, a parent creates or fabricates medical symptoms in a child as a result of the parent's own psychopathology (Chan, Salcedo, Atkins, & Ruley, 1986;Libow & Schreier, 1986). The most common medical presentations have included apnea, seizure disorders, recurrent vomiting, recurrent diarrhea, muscular weakness, and neurological problems (Kaufman et al., 1989). Serial MSP has also been documented, in which more than one child in the family was victimized (Alexander, Smith, & Stevenson, 1990). The syndrome does not involve real medical illness or psychosomatic components. Nor is it hypochondriasis, in which there is a sense that one truly is or will become ill. Rather, it is a factitious disorder with physical symptoms (American Psychiatric Association, 1987), involving intentional production or reporting of physical (but not psychological) symptoms in the child by the PAUL ROBINS, PhD, is a pediatric psychologist in the Division of Psychology, Alfred I. duPont Institute, Wilmington, Delaware, where he is the Director of the Attention-Deficit Hyperactivity Disorder Program and the Codirector of Training.
