Self-ratings of health are central measures of health status that predict o
utcomes such as mortality and declines in functional ability. Qualitative a
nd quantitative data are used to test the hypothesis that definitions of he
alth that are narrowly biomedical are associated with underestimates of sel
f-ratings relative to respondents' medical histories, while definitions tha
t are broad and inclusive are related to relatively better self-ratings. A
sample of 159 elderly African Americans rates their health and reports "wha
t went through your mind." Analysis of variance shows that respondents who
overestimate their health are more likely to report ratings based on social
activities and relationships, or psychological, emotional, or spiritual ch
aracteristics, rather than biomedical criteria. The authors conclude that i
nclusive definitions of health facilitate more positive self-ratings of hea
lth, given a fixed health status; methodologically, they conclude that this
is a promising method for exploring self-ratings of health.
