The relationship between cynical hostility and blood pressure reactivity

Area of Science:

• Psychophysiology
• Cardiovascular Health
• Behavioral Medicine

Background:

• Elevated blood pressure is a significant risk factor for cardiovascular disease.
• Hostility, a personality trait, has been previously suggested to influence cardiovascular responses.
• Understanding factors contributing to blood pressure hyperresponsivity is crucial for preventative health strategies.

Purpose of the Study:

• To investigate the association between hostility levels and blood pressure reactivity to acute stressors.
• To determine if cynical hostility predicts exaggerated blood pressure responses in normotensive adults.

Main Methods:

• Seventy-six normotensive adults participated in the study.
• Hostility was assessed using the MMPI (Minnesota Multiphasic Personality Inventory) hostility subscale (Cook-Medley).
• Blood pressure reactivity and recovery were measured during cold pressor and mental arithmetic stress tests on two separate occasions.

Main Results:

• A significant correlation between Cook-Medley hostility and blood pressure reactivity was not consistently observed (only 1 of 20 correlations was significant).
• Blood pressure reactivity was significantly influenced by sex and family history of cardiovascular disease.
• No interaction was found between hostility and sex or family history regarding blood pressure reactivity.

Conclusions:

• The study found no evidence supporting the hypothesis that cynical hostility, as measured by the Cook-Medley scale, is associated with increased blood pressure reactivity to laboratory stressors.
• Sex and family history of cardiovascular disease appear to be more significant predictors of blood pressure reactivity than hostility in this cohort.
