The purpose of this paper is to solve the challenges in knowledge outcome (e.g. knowledge contribution, knowledge exploration) improvement at the post-adoption phase in the context of e-communities. This study develops a model by integrating dedication-constraint framework and self-presentation theory. The model proposes that knowledge outcomes at the post-adoption phase rely on relationship development between community members, conceptualized as commitment. The authors also hypothesize that members’ perceived online self-presentation quality, theorized as personal control and social influence, serves as the key means to motivate members’ commitment.


This study used survey instrument to collect data and adopted partial least squares to test the proposed hypotheses.


The results show that perceived online self-presentation quality positively affects relationship development, which in turn affects continuance intention for knowledge outcomes.

Research limitations/implications

This study expands the dedication-constraint framework by integrating the self-presentation theory. This study contributes new knowledge by proposing a model that delineates the relationship between online self-presentation quality, relationship development, and knowledge outcomes at the post-adoption stage.

Practical implications

This study shows that members’ perceived online self-presentation quality affects both affective commitment and calculative commitment, which in turn affect knowledge outcomes, suggesting the important role of the perceived quality in stimulating a member’s post-adoption reactions.


This study contributes to the research on post-adoption behavior in an e-community context by accounting for the influence of e-community features in self-presentation quality and dedication-constraint mechanisms on post-adoption phenomena.
