the mediating role of organizational citizenship behavior in impact of job attitudes on knowledge sharing behavior

the aim of current research is to determine how factors of job attitude, subjective norms regarding knowledge sharing, and perceived behavioral controls affect knowledge sharing behavior, considering the role of organizational citizenship behavior as a mediating factor. to achieve this purpose, the research data was collected by providing research questionnaire in 384 members of the hospital staff and was analyzed through structural equation model (sem). the results indicate that among the dimensions of job attitude, job involvement and organizational commitment directly, and job satisfaction directly and indirectly lead to sharing knowledge across the organization. in addition, behavioral control indirectly, and subjective norm directly and indirectly affect knowledge sharing behavior. thus, it can be said that organizational citizenship behavior does not play the mediatory role just in the job involvement-knowledge sharing and organizational commitment-knowledge sharing relationships. in other words, job involvement and organizational commitment only directly contributes to knowledge sharing among employees. these research findings refer to the necessity of considering organizational citizenship behavior in sharing knowledge among organizational staff.
