Keeping hostility in perspective: coronary heart disease and the Hostility Scale on the Minnesota Multiphasic Personality Inventory.

Three prospective studies from the early 1980s found that high scores on the Hostility (Ho) Scale of the Minnesota Multiphasic Personality Inventory (MMPI) were associated with an increased incidence of coronary heart disease (CHD) and mortality from CHD and other causes. In the current study, the association between the Ho score and subsequent health status was examined in a 20-year follow-up of 620 general medical patients who completed the MMPI between 1962 and 1965. Univariately, the Ho score from the MMPI was a significant factor for predicting the development of CHD, CHD-related mortality, and total mortality. When two simple risk factors for CHD--age and sex--were also considered, however, the MMPI Ho score was no longer a significant predictive factor.
