Product type and word of mouth: a dyadic perspective

Abstract

PurposeStrong evidence suggests that word‐of‐mouth (WOM) communication varies in its influence according to product type; however, empirical research remains deficient. The purpose of this paper is to propose a procedural model to examine the influence of product type on both the effect and spread of related WOM information at the same time.Design/methodology/approachUsing a self‐administered questionnaire, a sample of 895 consumers across 16 different products was collected; results were analyzed using structural equation modeling.FindingsWOM was found to be more influential and more widely spread for services than for goods. In addition, although the level of receivers' perceived risk (PR) is generally assumed to be a significant antecedent of WOM influence (WI), the results of the study indicate that PR is not a direct function of WI. Instead, WOM request (WR) mediates the effect of PR on WI.Originality/valueTo the authors' knowledge, this is the first study to examine the relationship between product type and WOM from a dyadic perspective. Moreover, the authors introduced two important mediators – namely, PR and WR – in the model in order to identify different potential effects of WOM in a seeker‐initiated context. The results of this study will enhance knowledge about the influences of WOM information.
