The new paper explores the findings of two studies about relationships. In the first, involving more than 270,000 people in nearly 100 countries, author William Chopik found that both family and friend relationships were associated with better health and happiness overall. But at advanced ages, the link remained only for people who reported strong friendships.
“I went into the research sort of agnostic to the role of friendship,” says Chopik, assistant professor of psychology at Michigan State University. “But the really surprising thing was that, in a lot of ways, relationships with friends had a similar effect as those with family—and in others, they surpassed them."
For the other study, Chopik analyzed a separate survey of nearly 7,500 older people in the U.S. Here, he found that it wasn’t just important to have friends, but that the quality of those friendships also mattered.
