Blood pressure responses of defensive hostile women when facing a real stress task.

OBJECTIVE

This study investigated the importance of the combination of the hostility and defensiveness variables as psychosocial factors that predict the risk of cardiovascular dysfunction. We examined the impact of a stressful situation on blood pressure responses, using a continuous psychophysiological assessment approach.

DESIGN

We measured the evolution of these responses over three experimental phases (adaptation, task and recovery), also considering a minute-by-minute analysis within each phase.

MAIN OUTCOME MEASURES: We used the Cook-Medley Hostility Scale and the Social Desirability Questionnaire to form four groups (high hostility and high defensiveness, high hostility and low defensiveness, low hostility and high defensiveness, and low hostility and low defensiveness).

RESULTS

We expected the group of hostile defensive women to record higher activation (task phase: an academic exam) and slower habituation (recovery phase) compared to the other groups. The results confirmed our hypothesis, as the profile of the hostile defensive individuals was one of constant or sensitization during the task phase, while during the recovery phase those individuals underwent a slow recovery.

CONCLUSION

Therefore, it can be indicated that the low hostility and low defensive group is the most adaptive, as recorded very little activation in response, and rapid recovery.
