The impact of mixed eWOM sequence on brand attitude change: cross-cultural differences

Purpose Despite the importance of electronic word-of-mouth (eWOM) in e-commerce transactions on the global market, there is still limited understanding about the effect of eWOM sequence and its psychological mechanism in cross-cultural settings. Therefore, the purpose of this paper is to investigate the differences in brand attitude changes according to the eWOM sequence, as well as cross-culturally, based on thinking styles. Furthermore, the authors examine the moderated mediation effect of perceived cognition congruency across cultures to explain its underlying mechanism. Design/methodology/approach The authors use a 2 (eWOM sequence: positive/negative, negative/positive) × 2(culture: East (South Korea), West (USA)) factorial design. Perceived cognition congruency is measured as a within-group variable. Findings First, brand attitude changes in the West (USA) for the negative/positive presentation order are significantly larger than for the positive/negative presentation order, while, in the East (South Korea), no significant differences exist. Second, in the Westerner group (analytical thinking style), the perceived cognition congruency shows a significant difference according to the eWOM sequence, whereas in the Easterner group (holistic thinking style), the perceived cognition congruency does not show a significant difference according to the eWOM sequence. Practical implications As such, a strategic interpretation of the mixed eWOM presentation order across cultures is needed. In the West, interest and attention are necessary for the eWOM sequence. However, in the East, a different strategic approach, except for the presentation order of mixed eWOM, is required. The other elements of the mixed eWOM, such as attribute type or intensity of negative information, need to be considered for mixed eWOM management. Originality/value This study expands the existing body of knowledge on the sequence effect of mixed eWOM. Furthermore, it provides strategic direction and practical implications for mixed eWOM-driven information management, focusing on sequence in cross-cultural settings.
