A structured questionnaire based on a nonprobability purposive sample resulted in 413 responses, from which a structural equation model was developed. The results demonstrate that perceived trust significantly influences membership among a virtual group, and membership subsequently affects eWOM. From a sample drawn among international participants of a sporting event in Taiwan, results demonstrate the positive relationship and importance of perceived trust in creating a sense of membership among athletes.
