The formation and maintenance of satisfying romantic relationships, a developmental milestone for many emerging adults, has been challenged by the negative impact of the COVID-19 pandemic. Yet, the impact of COVID-19 stress on relationship satisfaction has not been explored within the context of individual and relationship factors. Guided by a socio-ecological framework, this study used a longitudinal design to investigate the impact of individual-level (i.e., growth beliefs, destiny beliefs), couple-level (i.e., daily criticism), and societal-level (i.e., COVID-19 stress) factors on relationship satisfaction during Fall 2021. We also explored the moderating effects of destiny beliefs and growth beliefs. Results revealed relationship satisfaction was negatively associated with daily criticism, but not directly associated with destiny beliefs, growth beliefs, or COVID-19 stress. However, growth beliefs buffered against the negative impact of criticism on relationship satisfaction. These findings are consistent with the notion that growth beliefs may play a protective role in relationship processes.
