The Common Fate Mediation Model: Does Communication of Ideals Mediate the Relationship between Ideal Similarity and Relationship Satisfaction?

Iulia Diana Preotu, Maria Nicoleta Turliuc


The aim of our study is to test whether the communication of ideals mediates the relationship between ideal similarity and relationship satisfaction using the Common Fate Mediation Model (Ledermann & Macho, 2009). To assess mediation using Structural Equation Modeling, a general three-step procedure is suggested: (1) the selection of a good fitting model, (2) testing the direct effects and (3) testing the mediating effect by means of bootstrapping. One-hundred couples completed several scales assessing ideal similarity and communication based on the Ideal Partner and Relationship Scales (Fletcher at al., 1999) and relationship satisfaction using the Dyadic Adjustment Scale (Spanier, 1976). The results indicate (1) a good model fit, (2) both direct effects that constitute the indirect effect are significant, but the direct effect of similarity on satisfaction is not and (3) the bias-corrected (and the percentile) bootstrapped confidence limits revealed a significant indirect effect, providing evidence that the communication of ideals fully mediates the relationship between perceived ideal similarity and dyadic satisfaction.
