This essay extends the relational turbulence model as a framework for understanding communication in romantic relationships. Following the relational turbulence model, relational turbulence theory identifies relational uncertainty and interdependence as parameters that shape subjective experiences, but the theory clarifies the theoretical processes underlying their distinctive effects. In addition, relational turbulence theory articulates causal processes linking cognitive appraisals and emotions to communication. Relational turbulence theory also describes how episodes characterized by biased appraisals, intense emotions, and volatile communication coalesce into global evaluations of relationships as turbulent. In turn, the theory addresses the effect of relational turbulence on personal, relational, and social outcomes. Finally, the theory explains how communication can contribute to the development of both turbulence and resilience in romantic relationships.
