Abstract: | This study examined the relations of one’s own total trait hostility and one’s spouse’s hostility as influences on cardiovascular
(CV) responses to couple interactions (including conflict discussions) in 45 married couples aged 24—50. Systolic blood pressure
and cardiac index (CI) reactivity to conflict discussion and recovery after conflict was greater in low hostile males if they
were interacting with high hostile wives (p < .02). Vascular resistance index (VRI) reactivity to interactions was greater
in high hostile husbands with high hostile wives (p < .05). Women showed no adverse CV effects of having a hostile spouse
when their own hostility was low. Instead, seeming to anticipate the subsequent couple interactions, wives from duos in which
both partners were high in hostility had higher baseline VRI levels and lower baseline CI compared to wives from duos in which
both were low in hostility (ps < .05), and they simply maintained these group differences with no greater CV reactivity during
the interactions. Findings suggest that CV responses before, during, and after marital discussions, particularly those characterized
by conflict, may be influenced not only by one’s own hostility but by the hostility of one’s partner as well. |
