Happiness Increases with Age, Across Generations

By admin on February 11, 2013

Psychological well-being has been linked to many important life outcomes, including career success, relationship satisfaction, and health. A new report published in Psychological Science, reveals that self-reported feelings of well-being tend to increase with age, but that a person’s overall level of well-being depends on when he or she was born.

Psychological scientist Angelina R. Sutin of Florida State University College of Medicine conducted the study while at the National Institute on Aging (NIA) at the National Institutes of Health (NIH), where she remains a guest researcher. She and colleagues at NIA predicted that people in the same “birth cohort” — born around the same time — may have had unique experiences that shape the way they evaluate happiness and optimism. They hypothesized that the level of well-being a person reports would, therefore, vary according to his or her birth year.

Mounting evidence suggest that happiness might be at least as powerful a predictor, if not a more powerful predictor than some of the other lifestyle factors such as diet and physical activity.

Andrew Steptoe, the British Heart Foundation Professor of Psychology at University College London, has found that happier people also have greater protection against things like heart disease and stroke.

“We know that stress which has bad effects on biology, leads to those bad changes as far as health is concerned,” said Mr Steptoe.

“What we think is happening is that happiness has the opposite effect and has a protective effect on these same biological pathways”.

Psychologists have long argued that people have a “set point” for happiness. Regardless of what life brings, the set-point theory goes, happiness levels tend to be stable. A big life event could create a boost of joy or a crush of sorrow, but within a few years, people return to a predetermined level of life satisfaction, according to the theory.

Using two large-scale longitudinal studies, NIH’s Baltimore Longitudinal Study of Aging (BLSA) and the CDC’s National Health and Nutrition Examination Survey (NHANES), Sutin and colleagues looked at data from several thousand people over 30 years, including over 10,000 reports on well-being, health, and other factors.

When the researchers analyzed the data across the whole pool of participants, older adults had lower levels of well-being than younger and middle-aged adults.

But when Sutin and her colleagues analyzed the same data while taking birth cohort into account, a different trend appeared: Life satisfaction increased over the participants’ lifetimes. This trend remained even after factors like health, medication, sex, ethnicity, and education were taken into account.

So what explains the different results?
