Jason Schnittker (U-Penn) quoted on self-rated health by older adults
"Why So Many Older Americans Rate Their Health As Good Or Even Excellent" - Kaiser Health News. 6/13/2019.
"Older people expect some deterioration in health and aren't thrown off course in the same way when it occurs," said Jason Schnittker, a professor of sociology at the University of Pennsylvania who has studied self-rated health.
"Lest you think older adults' bias toward positivity is a sign of denial or a lack of objectivity, a large body of research shows it's highly meaningful. "Self-rated health is very strongly predictive of longevity" as well as other outcomes such as cognitive health and use of health care services, Schnittker noted."
