Abstract
Introduction: This study aimed to compare the activity systems of brain/behavioral in hypertensive patients with and without medication and normal individuals.
Method: No. of 163 patients and visitors were selected by convenience sampling method in Boo Ali Sina General Hospital in Qazvin. They were 56 persons (29 women and 27 men) in hypertensive group with medication use and 51 persons (28 women and 23 men) in other hypertensive group without medication use and 56 persons (26 women and 30 men) in normal individual group. After measuring the blood pressure of each person, personality questionnaire for activity systems of brain/behavioral were completed by subjects.
Results: ANOVA analysis showed significant differences between studied groups in Behavioral Inhibition System (BIS) and affray/escape and avoidance components of the verb be, bring the behavior, active avoidance and contention. In Behavioral Activation System (BAS) and off/escape components, the differences were not significant. Following up the results by TUKEY exam showed that there are no significant differences in both hypertensive groups for none of the systems and components. The Behavioral Inhibition System (BIS) in hypertensive group with the medication use was significantly more than the normal individual group. Behavioral Activation System (BAS) was no significant difference between groups. Healthy score in active avoidance component were significantly higher than other two groups. The score of hypertensive group with medication use in passive avoidance and fight-flight system (FFS) and the score of hypertensive group without medication use in behavioral approach and fight system were significantly more than healthy group.
Conclusion: People with high blood pressure in BIS and FFS system were more active and less active in BAS system. Accordingly, people with high blood pressure have greater tendency to have negative emotions.
