In older adults, social contacts and a sense of purpose are linked, according to research in the psychological and neurological sciences.
The findings of the research were published in the July 2022 issue of the American Journal of Geriatric Psychiatry, apply to both working and retired adults, the research found that for better and for worse these interactions are more strongly correlated to purposefulness in people who are retired.
"Specifically for our retired older adults, this is a construct we should really care about," said Gabrielle Pfund, who led the study as a PhD student in the lab of Patrick Hill, associate professor of psychological and brain sciences. Pfund graduated in June and is now at Northwestern University.
The research team worked with a group of some 100 adults with an average age of about 71. For 15 days, participants were asked three times daily about the quality of the social interactions they'd had that day. Every evening they were asked to use a scale of one to five to answer the question: How much do you think your life had a purpose today?
After analyzing the responses, they found -- relative to each person's own baseline -- the more positive interactions a person had during the day, the more purposeful they reported feeling in the evening. Other measures, including employment and relationship status, did not predict a person's sense of purpose.
What is a sense of purpose?
Having a sense of purpose is defined as the extent to which one feels that they have personally meaningful goals and directions guiding them through life.
Of note, Pfund said, the study also showed how dynamic a person's own sense of purpose could be.
"Most research on sense of purpose is focused on big-picture orientation of someone being purposeful versus someone being not purposeful," she said. But it turns out, purposefulness may be more dynamic.
Although some people do tend to be generally more or less purposeful overall, Pfund said, "We found purpose can change from day to day. Everyone was experiencing fluctuations relative to their own averages."
The association was much stronger in retired people, the data showed: more positive social interactions showed a stronger association with a higher sense of purpose while more negative interactions were more strongly tied to a lower sense of purpose.
"For everyone, but specifically for our retired older adults, the people in their lives really matter," Pfund said.
The research has its limitations, two among them being that the sample was taken from data collected in Zurich, Switzerland, and the respondents were typically in good health. These findings may look different in other countries or amongst older adults with poorer health.
Having a sense of purpose is about more than feeling good. Prior research has shown that adults with a higher sense of purpose lead longer, healthier and happier lives. They have lower rates of Alzheimer's disease and heart and other cardiovascular problems.
"The people in your life are going to have a very, very big impact on that," she said. "If you find yourself surrounded by people who bring you down ... that's going to have an impact.
"On the flipside, if you're surrounded by people who lift you up and who infuse your life with positivity, that's going to have an impact, too."
And that, she said, was good news.
"If you're feeling like your life has no purpose, that's not how it's always going to be. That's not your life. That can change."
