Thp bereavement literature has yet to shown consensus on a clear definition
of normal and abnormal or complicated grief reactions. According to DSM-IV
: bereavement is a stressor event that warrants a clinical diagnosis only i
n extreme cases when other DSM categories of psychopathology (e.g, Major De
pression) are evident. In contrast, bereavement theorists have proposed a n
umber of different types of abnormal grief reactions, including those in wh
ich grief is masked or delayed. In this article, we review empirical eviden
ce on the longitudinal course, phenomenological features, and possible diag
nostic relevance of grief reactions. This evidence was generally consistent
with the DSM-IV's view of bereavement and provided little support for more
complicated taxonomies. Most bereaved individuals showed moderate disrupti
ons in functioning during the first year after a loss, while more chronic s
ymptoms were evidenced by re relatively small minority. Further, those indi
viduals showing chronic grief reactions can be relatively easily accommodat
ed by existing diagnostic categories. Finally, we found no evidence to supp
ort the proposed delayed grief category. We close by suggesting directions
for subsequent research. (C) 2001 Elsevier Science Ltd. All rights reserved
