The present study tested several pathways detailed in the theory of resilience and relational load (TRRL) in the context of urban couples living together during the COVID-19 pandemic. Fifty cohabitating couples completed a baseline assessment and 7 days of daily diaries. Results indicated that, the more an individual or their partner reported being communally oriented within their relationship at baseline, the greater that individual’s relational thriving each day. Results also revealed that, the more an individual reported being communally oriented, the more they viewed their partner as engaging in self-disclosure each day. Two indirect effects emerged, such that one’s own communal orientation positively predicted their perceptions of their partner’s self-disclosure, which in turn predicted greater individual and relational thriving. These findings and their implications for the TRRL, couples’ communication, and coping with pandemic-related stress are discussed.
