Prior research suggests that financial strain negatively impacts relational outcomes and that fluctuations (i.e., volatility) in daily reports of relationship aspects may be detrimental for relational outcomes. Daily relational uncertainty may also be associated with financial stressors; however, little is known about the association between financial strain and levels of daily relational uncertainty, as well as the volatility in day-to-day relational uncertainty. The current study includes both members of 100 adult different-sex couples (relationship length M = 7.0 years, SD = 7.1) who completed 14 days of daily diaries. We examined whether greater baseline financial strain is associated with higher levels of daily relational uncertainty and greater day-to-day volatility in relational uncertainty among actors and partners. Individuals who reported greater financial strain also reported higher overall levels of daily relationship uncertainty, as well as greater volatility in daily relationship uncertainty. The association between actor financial strain and volatility in daily relationship uncertainty was moderated by gender and marital status, such that financial strain was only associated with greater volatility in daily relationship uncertainty for men (but not for women) and for unmarried (but not married) individuals. Evidence for partner effects were also found, where partners’ higher levels of financial strain was associated with less volatility in actors’ daily relational uncertainty; however, this relationship was moderated by income, gender, and marital status. Individuals with lower income levels (versus high income levels) reported less volatility in their daily relationship uncertainty when their partners reported higher financial strain. Males rather than women reported lower volatility in daily relational uncertainty when their partners reported greater financial strain. In addition, unmarried rather than married individuals reported greater volatility in daily relationship uncertainty when their partners reported higher financial strain. Implications for future research and practice are discussed.
