The relationship between Internet addiction and negative eWOM

Customers prevalently use social media (SM) to post their experiences and to review others’ experiences. This study investigated how Internet addiction (IA) influenced customers’ word-of-mouth behaviors on SM after a service failure, focusing on both young and older customers. Two experiments were conducted. The first study was conducted with young customers and second experiment with older customers. Results suggest that the group of young customers had significantly higher levels of IA, compared to older customers. The analysis identified that IA and functional/technical service failure partially influenced four negative types of electronic word-of-mouth (eWOM) (i.e. Badmouthing, Tattling, Spite, and Feeding the Vultures). Both young and older customers tended to show more negative eWOM types for technical service failures. For the functional service failures, IA was the main predictor of negative eWOM for both young and older customers.
