Abstract
The present study examined the role of personality as a predictor of mortality among patients with chronic renal insufficiency. A prospective evaluation of the influence of personality on patient survival was conducted over an average 49-month period. Cox regression was used to evaluate the effects of 5 dimensions of personality in a sample of 174 patients (100 male and 74 female). At follow-up, 49 patients had died. Significant demographic and clinical predictors of survival included age, diabetic status, and hemoglobin level. After these predictors were controlled for, 2 personality traits, conscientiousness and neuroticism, predicted patient mortality. Patients with high neuroticism scores had a 37.5% higher estimated mortality rate. Patients with low conscientiousness scores had a 36.4% increased mortality rate.
