Physicians’ willingness to share: a TPB-based analysis

Physicians’ willingness to share knowledge is a central antecedent of effective knowledge sharing within hospitals. This paper aims at supporting the micro‐foundation of knowledge sharing with the identification of the factors that affect willingness to share and their classification according to a behavioural model grounded in the Theory of Planned Behaviour (TPB). The identification of antecedents and their classification is based on the review of the major contributions published on top tier and specialist journals. This study identifies 22 factors that affect physicians’ willingness to share. These factors are classified according to the TPB framework, which identifies three behavioural antecedents: attitude, subjective norm and perceived behaviour control. The organization of the factors allows appreciating the diffusion of knowledge‐sharing behaviours as the result of three concurring perspectives: raising attention to the benefits of knowledge sharing, building up social pressures from relevant actors and designing appropriate organizational contingencies.
