Sex typing and the coronary-prone behavior pattern

The purpose of this study was to examine the relationship between sex-role orientation and the coronary-prone behavior pattern [Type A]. Ninety-six males and eighty-four females were administered the Bem Sex Role Inventory and the student version of the Jenkins Activity Survey. The results showed that, irrespective of sex, Type A subjects were significantly more instrumental (masculine) and less expressive (feminine) than Type B subjects. Consistent with previous research females were found to be more expressive than males; however, the sole predictor of instrumentality was A/B classification. The potential significance of these findings for refining predictions of coronary artery and heart disease is discussed and recommendations for future research are offered.Portions of this paper were presented at the Third Annual Meeting of the Society of Behavioral Medicine, Chicago, March 1982.
