Type A and social support.

This investigation tested Matthews's hypothesis, which proposed that reduced social support may be one of the mediators of susceptibility to coronary disease in Type A individuals. In addition, sex differences were hypothesized to be an important aspect of the findings. Subjects were 72 women and 57 men undergraduate students who completed the Jenkins Activity Survey (JAS) and the Sarason Social Support Questionnaire. For women, both the Type A and Speed and Impatience subscales of the JAS were negatively related to satisfaction with social support. For men, however, Type A scores on JAS were positively correlated with satisfaction with social support. The implications of these findings, particularly with regard to the importance of separate analyses by sex, are discussed.
