Stress, Dyadic Coping, and Relationship Instability During the COVID-19 Pandemic

How romantic partners respond to stress has important implications for the well-being of their relationship. In this study, we examined the effects of three types of stress on relationship instability and evaluated individuals' perceptions of their partner's dyadic coping as a mediator in a sample of 117 different-gender couples (N = 234) across 6 months of the COVID-19 pandemic. We found that perceived stress, but not economic pressure or pandemic concerns, was associated with increases in relationship instability for both men and women. For women but not men, perceived stress was negatively associated with dyadic coping, and dyadic coping was related to lower relationship instability. Although direct effects were present for most of the variables of interest, dyadic coping did not mediate the associations between stress and relationship instability for either partner. These findings underscore the direct paths between stress, adaptive responses, and relationship instability, building upon past theorizing and research on stress and dyadic coping.
