What drives users' participation in online social QA communities? An empirical study based on social cognitive theory

摘要

Purpose The purpose of this paper is to examine some drivers of users' participation in online social question-and-answer (Q&A) communities based on social cognitive theory and then identify the underlying mechanism of this process. Design/methodology/approach This study developed a research model to test the proposed hypotheses, and an online survey was employed to collected data. Totally, 313 valid responses were collected, and partial least squares structural equation modeling was adopted to analyze these data. Findings This study empirically finds that the outcome expectations (personal outcome expectations and knowledge self-management outcome expectations) are positively related to participation in online social Q&A communities. At the same time, users' self-efficacy positively influences their participation behaviors. It can not only directly motivate users' participation, but also indirectly promote participation behaviors through the two dimensions of outcome expectations. Besides, perceived expertise and perceived similarity are two positive and significant environmental elements affecting users' participation. Originality/value This study extends the understanding about how participation behaviors will be motivated in the context of online social Q&A communities. Drawing on the social cognitive theory, constructs were established based on the features of these communities. Meanwhile, some mediating effects in the motivating process were also discussed.
