Why the study?
Do depressive symptoms and trait aggression interact to increase cardiovascular reactivity to a laboratory stressor in healthy females?
Do depressive symptoms and trait aggression interact to increase cardiovascular reactivity to a laboratory stressor in healthy females?
Depressive symptoms and verbal aggression interact to exaggerate blood pressure responses to acute stress in healthy women, highlighting a potential psychophysiological mechanism for cardiovascular risk.
Identifies verbal aggression as moderator of depression-BP reactivity links; extends observational evidence but leaves open clinical translation.
BACKGROUND: Depression and anger/aggression-related traits are thought to promote coronary disease, at least in part, through their associations with stress-related cardiovascular processes. It is unclear whether the effects of these factors on cardiovascular reactivity (CVR) are redundant, additive, or synergistic. PURPOSE: The main goal of this study was to examine the independent and interactive effects of depressive symptoms and anger/aggression-related traits in promoting CVR. METHODS: Participants were 63 healthy females who completed the Beck Depression Inventory and Buss-Perry Aggression Questionnaire and performed a stressful speaking task. Systolic and diastolic blood pressure (SBP and DBP) and heart rate were recorded. RESULTS: Significant interaction effects indicated that depressive symptoms were positively associated with SBP and DBP reactivity among women high in verbal aggression but not among those low in verbal aggression. CONCLUSIONS: Depressive symptoms and verbal aggression may interact to promote exaggerated blood pressure responses to stressors, a possible marker for mechanisms that contribute to heart disease.
