This study investigated relational uncertainty as a mechanism through which perceived partner humor use affects recipient’s relationship satisfaction. Two hundred individuals completed measures of their partners’ perceived positive and negative humor use, their relational uncertainty and relationship satisfaction. Results reveal that perceived partner’s positive relational humor use predicted greater relationship satisfaction, and perceived partner’s negative relational humor use predicted diminished relationship satisfaction. Further, relational uncertainty mediated relationships between perceived partner positive humor and satisfaction and perceived partner negative humor and satisfaction.
