Testing the predictive and theoretical validity of the network uncertainty measure

The present study explores the network uncertainty measure (NUM) as a longitudinal determinant of both relational uncertainty and biased cognitions (the perception that relational talk is threatening) at a later time. Using relational turbulence theory (RTT) as a framework, the NUM was tested for predictive and theoretical validity. Results indicated that network uncertainty at time 1 predicted self and partner, and relationship uncertainty at time 2 with varying strength of relationships. Moreover, the NUM predicted biased cognitions at time 2 when controlling for self, partner, and relationship uncertainty. Efforts were made to see if relational uncertainty mediates the relationship between network uncertainty and biased cognitions. Those results were nonsignificant. These clarify the nature of uncertainties both within and outside of close relationships. Implications are discussed in terms of both theoretical and conceptual development.
