6.1. Theoretical issues
The point of departure for this study was the need to investigate antecedents of WOM referral behavior by customers who are still engaged in a service and who have not experienced the service outcome. While there has been a significant focus on the role of relational constructs in stimulating positive WOM communication, there has been less attention given to factors that motivate current customers in long-term service interactions. Second, while customer expectations have been explored as drivers of constructs such as customer satisfaction, the direct effect of outcome confidence on outcomes such as WOM referral has not received much attention in the literature. Furthermore, the interaction between outcome and process elements of service quality in driving WOM behavior has largely been ignored.
At the theoretical level, this study contributes to the literature by outlining how outcome confidence directly predicts pre-outcome WOM referral behavior. The findings of the study provide support for the assertion that outcome confidence contributes to customers’ engagement in positive WOM behavior. Secondly, the study contributes to the literature by modelling pre-outcome WOM referral behavior as an interplay between present experience (employee service quality) and anticipations of the future (outcome confidence). To the authors’ knowledge, this is one of the first studies to do so.
