Hostility as a health risk factor: relationships with neuroticism, Type A behavior, attentional focus, and interpersonal style.

In order to investigate further the psychological construct of hostility measured on the Cook-Medley (Ho) Scale as a health risk factor, the present study examined relationships between hostility assessed on the Ho Scale and several measures of neuroticism, Type A behavior, and attentional and interpersonal style, using bivariate and hierarchical multiple regression analyses. Subjects were 204 psychologically normal, physically healthy males. Significant relationships were found between hostility, neuroticism, attentional overload, and interpersonal alienation. The present study provided normative data on several important health-related psychological dimensions in a sample of healthy normals. The findings also provided further support for the relationship between the hostility construct measured on the Ho Scale and measures of neuroticism as possible dimensions of disease-prone personality.
