DESIGN/METHODOLOGY/APPROACH : In total, 439 respondents who use at least one form of electronic banking service and who have previously received positive messages about electronic banking services from other customers were approached to complete a self-administered structured questionnaire. FINDINGS : Source credibility dimensions have a positive and significant relationship with PU. PU in turn has a positive and significant relationship with helping intentions and AIs as forms of customer citizenship. RESEARCH LIMITATIONS/IMPLICATIONS : The findings advance understanding of the extent to which customers rely on the perceptions of other customers in determining the usefulness of a service as well as their willingness to advocate the benefits of the service and help other customers. PRACTICAL IMPLICATIONS : The findings may guide retail banks in obtaining a greater understanding of the customer citizenship behaviour process and the extent to which banks can rely on customers to convince other customers of the benefits of electronic banking services. ORIGINALITY/VALUE : This study offers insight into the antecedents of the advocacy and helping intentions sub-dimensions of customer citizenship behaviour. It also explains how value between customers can be created by considering the elaboration likelihood model and social exchange theories, and customer citizenship behaviour.en© Emerald Publishing Limited 2018TrustworthinessExpertisePerceived usefulnessCustomer citizenship behaviourSource credibilityPostprint Article
