"The wellness of being is not just physical, but attitudinal," said Toshihiko Maruta, M.D., of the Mayo Clinic Department of Psychiatry and Psychology in Rochester and the principal author of the study, which appears in the August issue of Mayo Clinic Proceedings. "How you perceive what goes on around you and how you interpret it may have an impact on your longevity, and it could affect the quality of your later years."

Patients originally assessed in the 1960s with a personality test completed a follow-up self-assessment of their health status 30 years later. In the health survey, pessimists reported poorer physical and mental functioning. The results come two years after a Mayo Clinic study of the data found that optimists live longer than pessimists.

The researchers say, that to their knowledge, the two studies they've done are the first to report on the long-term health implications of explanatory style, an assessment of patients that classifies them as optimists, pessimists or mixed.

Researchers looked at the health survey results reported by 447 patients in the 1990s. This group had originally completed the Minnesota Multiphasic Personality Inventory (MMPI) between 1962 and 1965. The MMPI is an assessment that helps researchers classify personality traits. An optimism and pessimism scale was developed for the MMPI in 1994. Using the scale to determine how to classify the patients, researchers found that 101 were classified as optimistic, 272 as mixed and 74 as pessimistic.

Researchers said pessimists scored below optimists on quality-of-life assessments, and also scored lower than the national average on five of the eight scales that were measured. Those
