The term masochism, which was originally used in a specifically sexual
sense to determine masochistic perversion, has come to cover a wide v
ariety of clinical phenomena from the depressive-masochistic personali
ty to extreme forms of self-destructiveness. Moreover, the term is use
d at varied levels of abstraction: descriptive, dynamic, and as a meta
psychological construct. Because of the confusion engendered by its mu
ltiple meanings, many attempts at diagnostic and nosological clarifica
tion have been made. Psychodynamically, masochistic phenomena are mult
iply determined and serve multiple functions. While in the ''classical
'' view masochism was considered a drive phenomenon and, with respect
to ''moral masochism'', an unconscious need for punishment for incestu
ous oedipal wishes, a considerable amount of contributions has been em
phasizing its ''narcissistic'' functions: its role as a defense agains
t painful affects, especially the pain of separation, the establishmen
t of a symbiotic relationship with a mighty and idealized object whose
empathic mirroring is saught for, the possibility to gain illusory om
nipotent control over the object, and its role in defending against di
ssolution of self boundaries and fragmentation of the self. Structural
assessment seems to be necessary for an adequate understanding of the
predominant function masochism has in a given case.
