AbstractThis study examined social support as a mediator of susceptibility to coronary disease in Type A individuals. Sixty-four male subjects completed the Jenkins Activity Survey and the Sarason Social Support Questionnaire. The correlations between Type A scores, the speed and impatience and hard-driving competitiveness factors of the Jenkins survey, and Sarason's social support were found to be negative, which was contrary to earlier findings.¹ The authors hypothesize that these differing results may be a function of age and environment. Finally, and pertinent to the mechanism by which social support may be associated with coronary heart disease, systolic blood pressure was negatively correlated to satisfaction with social support.
