Cardiovascular profile of defensive hostile women in a real stressful situation

The main objective of this study was to analyze the impact of defensive hostility on cardiovascular response in a stressful situation. By measuring three of the most commonly used cardiovascular indexes (heart rate, systolic blood pressure and diastolic blood pressure) over three experimental phases (adaptation, task and recovery), the evolution of cardiovascular response was analyzed minute by minute throughout the entire experimental session, to check if the defensive hostility influences the cardiovascular function. Two scales were used: the Cook-Medley Composite Hostility Scale and the Marlowe-Crowne Social Desirability Scale. Based on the scores on these scales, there were formed four groups (high hostility and high defensiveness, high hostility and low defensiveness, low hostility and high defensiveness, and low hostility and low defensiveness). The stressful situation which was used in the task phase was a real academic examination (exam of the Psychology degree). The hypothesis was that cardiovascular response, activation and recovery, minute by minute, will be greater in hostile defensive women, with an intra-phase evolution profile characterized by maintenance or sensitization and slow recovery. Results show that defensive hostile individuals present the highest values in the physiological variables recorded, and less adaptive profiles.
