The Relationship between Students' Engagement and Student Knowledge Sharing Behavior in Tabriz Medical University: The Mediating Role of Self-Efficacy

The purpose of this study was to investigate the mediating role of self-efficacy in the relationship between students' engagement and their knowledge sharing behavior. The research method was descriptive-correlation based on structural equation model. The statistical population was 1752 students in Tabriz Medical University of whom 317 (149 males and 168 females) were selected by stratified random sampling. Data were collected using standard questionnaires of engagement by Schaufeli et al. (2006); self-efficacy by Shereret et al. (1982) and knowledge sharing behavior by Bock et al. (2005). Validity of the instrument was also confirmed by content validity and construct validity. The results showed that the correlation coefficient between engagement variable with self-efficacy and knowledge-sharing were positive and significant. The rate of this correlation ranges between 0.21 and 0.33. Also, students' engagement with coefficient 0.18 had a direct, positive and significant effect on self-efficacy. Moreover, self-efficacy had a direct, positive and significant effect on knowledge sharing with a coefficient of 0.24. As a result, the mediating role of students' self-efficacy in the relationship between engagement and knowledge sharing in the conceptual model of research was confirmed.
