The framingham Type A Scale: Cardiovascular and cognitive-behavioral responses to interpersonal challenge

Abstract

Most of the primary measures of Type A behavior have been found to be associated with physiological reactivity to stressors, as well as coronary heart disease (CHD). While it does predict CHD, the Framingham Type A Scale (FTAS) has not been conclusively linked to physiological reactivity. Similarly, in contrast to other Type A measures, little is known concerning the cognitive behaviors associated with the FTAS in stressful situations. The present study was conducted to evaluate the cardiovascular and cognitive-behavioral responses to interpersonal challenge of Type A versus Type B subjects, as classified by the FTAS. Type A's evidenced increased systolic blood pressure (SBP) reactivity and a greater degree of negatively toned cognitive activity than did Type B's. The SBP findings are consistent with those obtained with other measures of Type A behavior, and with the hypothesis that neuroendocrine reactivity mediates the link between the behavior pattern and CHD. The somewhat unique cognitive-behavior findings, however, may reflect important psychological differences among the various Type A measures.
