Hg. Prigerson et al., COMPLICATED GRIEF AND BEREAVEMENT-RELATED DEPRESSION AS DISTINCT DISORDERS - PRELIMINARY EMPIRICAL VALIDATION IN ELDERLY BEREAVED SPOUSES, The American journal of psychiatry, 152(1), 1995, pp. 22-30
Objective: This study sought to determine whether a set of symptoms in
terpreted as complicated grief could be identified and distinguished f
rom bereavement-related depression and whether the presence of complic
ated grief would Predict enduring functional impairments. Method: Data
were derived from a study group of 82 recently widowed elderly indivi
duals recruited for an investigation of physiological changes in berea
ved persons. Baseline data were collected 3-6 months after the deaths
of the subjects' spouses, and follow-up data were collected from 56 of
the subjects 18 months after the baseline assessments. Candidate item
s for assessing complicated grief came from a variety of scales used t
o evaluate emotional functioning (e.g., the Hamilton Depression Rating
Scale, the Brief Symptom Inventory). The outcome variables measured w
ere global functioning, medical illness burden, sleep, mood self-estee
m, and anxiety. Results: A principal-components analysis conducted on
intake data (N=82) revealed a complicated grief factor and a bereaveme
nt-depression factor. Seven symptoms constituted complicated grief: se
arching, yearning, preoccupation with thoughts of the deceased, crying
, disbelief regarding the death, feeling stunned by the death, and lac
k of acceptance of the death. Baseline complicated grief scores were s
ignificantly associated with impairments in global functioning, mood,
sleep, and self-esteem in the 56 subjects available for follow-up. Con
clusions: The symptoms of complicated grief may be distinct from depre
ssive symptoms and appear to be associated with enduring functional im
pairments. The symptoms of complicated grief, therefore, appear to def
ine a unique disorder deserving of specialized treatment.
