Knowledge contribution loafing and active participation in interest-based social network communities: the moderating role of self-disclosure

In interest-based social network communities, many members engage in knowledge contribution loafing (KCL) and do not participate actively in community activities. It is essential to investigate the factors associated with KCL and active participation to promote the development of interest-based social network communities. In this study, based on the Stimuli–Organism–Responses theory, we examined how disinhibition, privacy concerns, and risk aversion affected community members’ intention to engage in KCL, and how KCL further influenced active participation behaviour. We also explored the moderating role of self-disclosure. The data were collected through an online questionnaire survey, and we received a total of 628 valid responses. The results suggested that disinhibition, privacy concerns, and risk aversion were important predictors of KCL. In addition, KCL was negatively associated with active participation, and this relationship was moderated by self-disclosure. This study contributes to the existing body of knowledge on social loafing by investigating the accelerants and consequences of KCL. This study also has practical implications for the management of interest-based social network communities. Service providers can encourage members’ participation and reduce KCL by implementing different strategies to foster disinhibition, protect privacy, reduce potential risks, and promote self-disclosure in the community.
