The Personality Trait Linked To Poor Mental Health post image

Around one-in-five people are thought to have this personality type.

People who experience a lot of negative emotions and do not express them have more mental and physical health problems, research finds.

This is known to psychologists as a ‘type D’ personality: the ‘D’ stands for distressed.

People with a type D personality are likely to agree with statements like, “I am often down in the dumps”.

They are also likely to demonstrate social inhibition by agreeing with statements like, “I am a closed kind of person”.

Type D people are fearful of rejection if they express their negative emotions.

Around one-in-five people is thought to have a type D personality.

The study found that people who were type D tended not to report their health problems to a physician or nurse.

The study’s authors write:

“Type D patients were shown to report lower levels of health status, more cardiac symptoms, and more feelings of disability, when compared with non-Type D patients high on positive affect.”

The study involved 276 heart failure patients.

The results showed that heart failure patients who also had a type D personality were six times more likely to be in a worse state of health.
