'Personality genes' may help account for longevity

"But when we assessed the personalities of these 243 centenarians, we found qualities that clearly reflect a positive attitude towards life. Most were outgoing, optimistic and easygoing. They considered laughter an important part of life and had a large social network. They expressed emotions openly rather than bottling them up." In addition, the centenarians had lower scores for displaying neurotic personality and higher scores for being conscientious compared with a representative sample of the U.S. population.

"Some evidence indicates that personality can change between the ages of 70 and 100, so we don't know whether our centenarians have maintained their personality traits across their entire lifespans," continued Dr. Barzilai. "Nevertheless, our findings suggest that centenarians share particular personality traits and that genetically-based aspects of personality may play an important role in achieving both good health and exceptional longevity."

The study is titled "Positive attitude towards life and emotional expression as personality phenotypes for centenarians." The POPS was developed by lead author Kaori Kato, Psy.D., now at Weill Cornell Medical College, who validated it through comparisons with two previously established measures of personality traits. Other authors of the study were Richard Zweig, Ph.D., assistant clinical professor of psychiatry and behavioral sciences at Einstein and director of the Older Adult Program at Ferkauf, and Gil Atzmon, Ph.D., assistant professor of medicine and of genetics at Einstein.
