The authors studied the case material for patients treated with either psychoanalysis or brief therapy to examine the basis for the various states of pathological grief after berevavement. They view these states as intensifications or unusual prolongations of states found in normal grief and describe them in terms of the reemergence of self-images and role relationship models that had been held in check by the existence ofthe deceased person. This conclusion concerning preexisting mental schemata leads to an elaboration and partial revision of theories of regression, ambivalence, and introjection as causes of pathological grief.
