Predicting Behavior and Intention to Knowledge Sharing in Postgraduate Students Based on the Theory of Planned Behavior

Background: Knowledge sharing in university environments is essential and students' behavior in this field is based on their beliefs, norms and attitudes. Theory of planned behavior is one of the most prestigious behavior prediction models that can be used to examine the ideas, values, and attitudes in the context of knowledge sharing behavior. Considering the role of academics, especially postgraduate students in knowledge sharing, this study conducted with the aim of evaluating knowledge sharing behavior based on theory of planned behavior among postgraduate students. Methods: This descriptive study was conducted on 120 postgraduate students in school of public health of Shahid Sadoughi University of Medical Sciences through stratified sampling method in 2018. The data collection tool was a researcher-made questionnaire with confirmed reliability and validity. Data were analyzed by SPSS/16 included descriptive statistics, Pearson correlation, ANOVA, Independent T-test and linear regression as required. Results: The results showed that correlations between knowledge sharing behavior and intention with all theory of planned behavior constructs were statistically significant. The theory of planned behavior constructs explained 31.5% of the variances in knowledge sharing behaviors and 42.1% of the variances in knowledge sharing intention. Additionally, Subjective norms were the strongest predictor for behavior and attitudes were the strongest predictor for intention. Conclusion: In designing interventions aimed at improving knowledge sharing in universities, initially subjective norms should be addressed, then examined student's intention towards knowledge sharing. So, the theory of planned behavior may be used as a framework for educational interventions to improve knowledge sharing behaviors.
