“…People tend to be less satisfied with their relationship under conditions of relational uncertainty (e.g., Goodboy et al, 2020), and in interaction, individuals experiencing relationship distress tend to exhibit more negative behaviors (e.g., hostility, criticism, blame, defensiveness, withdrawal) and less positive behaviors (e.g., approval, empathy, affection; for review, see Balderrama-Durbin et al, 2020). Guided by research showing divergence between relational uncertainty and relationship quality as predictors of communication behavior (e.g., Knobloch et al, 2021; Knobloch & Theiss, 2017), we expect that relational uncertainty is negatively associated with dyadic synchrony over and above people’s reports of relationship quality. Formally stated:After covarying relationship quality, relational uncertainty corresponds with less dyadic synchrony via more frequent behavioral sequences of self-disclosure/hostility (H1) and validation/hostility (H2).
