The results were as follows. First, the customer satisfaction had both direct and indirect effects on trust mediated by contact intensity. Second, the trust had both direct and indirect effects on commitment mediated by relationship termination cost. Third, the commitment influenced long-term orientation. Finally, the empirical results confirmed that the model add to the concept of mediation with contact intensity and relationship termination cost plays a strong, central role in explaining relationship development process between customer and fashion retail stores.
