Investigating the consequences of word of mouth from a WOM sender’s perspective in the services context

Abstract

Employing scenario-based experiments, this paper examines the effect of word of mouth (WOM) on the sender's intention to give future WOM about the focal service provider and the self-enhancement derived from articulating WOM. Extant WOM literature considers self-enhancement as a key driver of positive WOM. This paper provides empirical evidence that a reverse effect exists and that self-enhancement is also an outcome of WOM behaviour. Results indicate that the impact of WOM on self-enhancement has substantive significance and holds for both positive and negative WOM. The effect of WOM on intentions is only partially supported. Finally, tie strength between the WOM participants partially moderates the relationship between the variables. Importantly, the impact of negative WOM is stronger than that of positive WOM.
