Understanding antecedents of continuance intention in social-networking services.

Given the extreme advances and large investments in social-networking services (SNS), it has become important to analyze users' decision-making processes in order to understand their continued use of SNS. This study attempted to develop an integrated model that incorporates subjective norm into the expectation-confirmation model. The research model was empirically tested within the context of Cyworld. The analysis revealed that the proposed theoretical model provided an in-depth understanding of user continuance behavior toward SNS. Theoretical and practical implications of this study are discussed.
