Stubbornness may actually be a trait that helps people live longer, a new study suggests.
Published this week in the academic journal "International Psychogeriatrics", the study examined the mental and physical health of elderly Italians living in a remote village nestled between the Mediterranean Sea and mountains. The researchers behind the study, who hail from the University of Rome La Sapienza and University of California San Diego School of Medicine, found many common personality traits between the elderly village residents, including stubbornness.
The research looked specifically at 29 individuals aged 90 to 101, comparing them to 51 younger family members aged 50 to 75. Interestingly, the older group was found to have better overall mental health, even though the younger group was physically healthier.
"The main themes that emerged from our study, and appear to be the unique features associated with better mental health of this [older] rural population, were positivity, work ethic, stubbornness and a strong bond with family, religion and land," Dilip V. Jeste MD, senior author of the study and senior associate dean for the Center of Healthy Aging and Distinguished Professor of Psychiatry and Neurosciences at UC San Diego School of Medicine, said in a statement.
To analyze the participants, the researchers used a quantitative rating scale as well as qualitative interviews. They discussed topics including migrations, traumatic events and beliefs with the elderly individuals. Younger family members were also analyzed using the same quantitative scale, while also being asked to describe the personalities of their older relatives.
"The [older] group's love of their land is a common theme and gives them a purpose in life. Most of them are still working in their homes and on the land. They think, 'This is my life and I'm not going to give it up,'" Anna Scelzo, first author of the study with the Department of Mental Health and Substance Abuse in Chiavarese, Italy, explained.
"We also found that this group tended to be domineering, stubborn and needed a sense of control, which can be a desirable trait as they are true to their convictions and care less about what others think," Scelzo said.
"This tendency to control the environment suggests notable grit that is balanced by a need to adapt to changing circumstances."
Many in the elderly group spoke about their passion for life, sometimes despite heartache and sadness.
"I am always thinking for the best. There is always a solution in life. This is what my father has taught me: to always face difficulties and hope for the best," one participant said.
The new study is also unique in that it examined long life from a psychological perspective.
"There have been a number of studies on very old adults, but they have mostly focused on genetics rather than their mental health or personalities," Jeste pointed out.
"Studying the strategies of exceptionally long-lived and lived-well individuals, who not just survive but also thrive and flourish, enhances our understanding of health and functional capacities in all age groups," he said.
So, while the study does not conclude that stubbornness is guaranteed to make you live longer, a strong correlation was noted. Jeste also points out that the study shows "well-being and wisdom increase with aging" despite a decrease in physical health.
Beyond stubbornness and strong mental health, numerous recent studies have suggested correlations between particular habits and longer life.
A survey of previous research published last month suggests that drinking three to four cups of coffee per day is connected with lower risks of premature death, heart disease, diabetes, liver disease, dementia and some cancers. Other scientific studies suggest that calorie restrictive diets, dancing and having sex regularly may all slow down the aging process as well.
