Personality was found significantly to mitigate the illness-provoking effects of stressful life events. Two groups of executives had comparably high degrees of stress over a 3-year interval, as measured by the Holmes and Rahe Schedule of Recent Life Events. One group (n = 86) suffered high stress without falling ill, while the other (n = 75) reported becoming sick after their encounter with stressful life events. Illness was measured by the Wyler, Masuda, and Holmes Seriousness of Illness Survey. Discriminant function analysis supported the prediction that high stress/low illness executives show, by comparison with high stress/high illness executives, more control, commitment, and interest in change as a challenge.
