An examination and proposed definitions of family members' grief prior to the death of individuals with a life-limiting illness: A systematic review.

We found grief occurring before the death of a person with a life-limiting illness, which we termed pre-death grief, is comprised of two distinct constructs: anticipatory grief and illness-related grief. Anticipatory grief is future-oriented and is characterized by separation distress and worry about a future without the person with the life-limiting illness being physically present. Illness-related grief is present-oriented and is characterized by grief over current and ongoing losses experienced during the illness trajectory. These definitions provide the field with uniform constructs to advance the study of grief before the death of an individual with a life-limiting illness.
