Background: Current paper aims at investigating factors affecting physicians'knowledge-sharing intention in teaching hospitals affiliated to Tehran University-Medical Sciences in which one of the most authentic model of behavior prediction namely planned behavior has been used as the theoretical framework of study. Materials and Methods: The method of current study is descriptive/survey correlational type and statistical society includes physicians employed in hospitals affiliated to Tehran University-Medical Sciences.Date was collected by questionnaires and analyzed using Lisrel;SPSS software.Confirmatory factor analysis was employed to evaluate consistency,Cronbach's alpha was used to assess reliability and structural equation modeling was used to fit the model and test hypotheses. Results: Prediction power of model for knowledge-sharing intention of physicians is(R2=0.66)The results suggested that impact of attitude on the knowledge-sharing intention is positive and significant with factor loading of(=0.87)However,influence of subjective norms and perceived behavioral control on the knowledge-sharing intention was not confirmed.Influence of subjective norms on attitude were evaluated positive and significant with factor loading of(=0.55)As a result, subjective norms affect knowledge-sharing intention through indirect mediation of attitude.All tests were significant at the level of(P0.01). Conclusion: According to findings of this research on improvement of knowledge-sharing behavior of physicians, health authorities need to take corrective measures to enhance the attitude and subjective norms of physician.
