This paper aims to determine whether prosocial motivation acts as a mediator between the individual motivation types of self-determination theory and knowledge sharing.
A partial least squares structural equation model (PLS-SEM) based on data collection (N = 303) ) was calculated, using “Smart PLS 3” software.
In respect of the influence of individual motivation types on knowledge sharing, it was found that prosocial motivation provides indirect mediation for external motivation and complementary mediation for introjected motivation, whereas it has no mediation effect on intrinsic and identified motivation.
Future research should consider the use of prosocial motivation as a mediator to reveal indirect effects that, otherwise, are at risk of remaining hidden.
To foster knowledge sharing within organizations, measures should be taken to increase external, introjected and prosocial motivation, as it was found that these types of motivation have a significant positive impact on knowledge sharing.
The current unanswered question – whether or not prosocial motivation acts as a mediator between the motivation types of self-determination theory and knowledge sharing – is examined, thereby providing insights into the hitherto largely unexplored role of prosocial motivation in knowledge-sharing models.
