A new study shows that a negative outlook on life can affect your survival chances in chronic illness.
Researchers at the University of Iowa report the first evidence of a strong link between personality type and the outcome in chronic kidney disease. They followed 174 patients, having assessed them with a personality questionnaire. Those who had a 'neurotic' personality - not necessarily depressed, but pessimistic and prone to worry - were less likely to survive over the next few years.

In contrast, those who were conscientious, goal-directed and willing to take on a challenge had the better survival prospects. It may be, say the researchers, that personality traits affect a person's willingness to follow a treatment regime or adopt a healthy lifestyle. Taking personality into account could be important for doctors and patients - helping pinpoint those who need more constant monitoring and encouragement.
