This paper aims to examine the role of trust in colleagues and its relationships with the factors of the theory of reasoned action (TRA). Specifically, this study examines the relationships among perceived social pressure about knowledge sharing, attitude toward knowledge sharing, behavioural intent to share knowledge, trust in colleagues and knowledge-sharing behaviour.
The methodology adopted was a questionnaire survey of employees working in 34 member institutions of the Singapore Association for Private Education (SAPE). These institutions form the entire member list of the SAPE as of 2020. A total of 297 employees completed a self-administered and anonymous survey using a cross-sectional design. Multiple linear regression was used to test the conceptual framework.
On the mediation effects, full mediation was found to affect attitude toward knowledge sharing on knowledge-sharing behaviour, and partial mediation was found to affect perceived social pressure on knowledge-sharing behaviour. On the moderation effects, trust in colleagues moderates both perceived social pressure and knowledge-sharing behaviour and attitude toward knowledge sharing and knowledge-sharing behaviour positively. Specifically, as the level of trust in colleagues increases, the impact of direct relationships also increases.
Data for the current study were obtained at a single point in time and self-reported. The findings may be biased because of common method variance. Furthermore, this study was conducted in a specific industry in Singapore, i.e. the private education institutions, which limits the generalisability of the research.
The results of this study indicate that managers need to encourage a higher level of trust between employees. Policies and processes could be enacted to promote building quality and trusting relationships between employees.
This study contributes to knowledge-sharing behaviour by integrating the role of trust with the TRA. This study extends the conceptual model of the TRA by providing a new theoretical perspective that takes into account the position of trust in knowledge sharing.
