Depressive Symptoms, External Stress, and Marital Adjustment: The Buffering Effect of Partner's Responsive Behavior.

Guided by theory emphasizing that partner responsiveness underlies well-functioning romantic relationships, we examined whether partners' responsive behavior buffered the degree to which a personal vulnerability (depressive symptoms) and external stress predicted declines in relationship adjustment. Using an existing dataset, we tested whether individuals' depressive symptoms and stress interacted with observer-coded partner responsive behavior during marital conflict discussions to predict change in marital adjustment at the next time point (N = 195 couples Time 1 to Time 2, 158 couples Time 2 to Time 3). Individuals experiencing greater (a) depressive symptoms or (b) stress showed sharper declines in marital adjustment. However, as predicted, the negative effects of both depressive symptoms and stress were attenuated when partners displayed high behavioral responsiveness. These findings underscore the importance of adopting a dyadic perspective to understand how partners' responsive behavior can overcome the harmful effects of personal and situational vulnerabilities on relationship outcomes.
