To determine why older people are optimistic, realistic, or pessimistic on
self-rated health relative to standard medical health measures, 48 persons
older than age 65 were interviewed in an in-depth, semistructured format. C
omparisons were made between optimists and poor-health realists, both of wh
om have serious health problems, to discover the ways in which these groups
develop their disparate self-ratings of health. When asked about the meani
ngs they attach to health, respondents variously referred to topics includi
ng family history, social comparisons, subjective age, and life expectancy
to form their ratings. These results begin to clarify the ways in which dif
ferent people view similar states of health, building on recent research sh
owing that health pessimists are at an elevated risk of mortality, while he
alth optimists reduce their mortality risk.
