A qualitative study examining the nurse-patient relationship has ident
ified the contagion of physical distress or 'compathy' as a significan
t but otherwise neglected phenomenon. Compathy occurs when one person
observes another person suffering a disease or injury and experiences
in one's physical body a similar or related distress. Thus, compathy i
s the physical equivalent to empathy. Although the contagion of physio
logical (compathetic) responses has been previously documented (for ex
ample, as couvade or psychogenic epidemics of the workplace), it has n
ot been theoretically explicated. Triggers for the compathetic respons
e are identified and include observing the suffering, hearing, or read
ing - or even thinking about - descriptions of the symptoms. The relev
ance of the compathetic response in the caregiving relationship and th
e necessity of suppressing the response when inflicting pain as a part
of providing therapy are described. The concept of compathy is analys
ed and defended.
