This study aimed to develop and test a model that identifies key antecedents of positive organizational behavior. A correlational research design was used, employing structural equation modeling for analysis. The study participants, selected through stratified random sampling, completed surveys on topics including organization-oriented self-esteem, leader-member exchange, role ambiguity, perceived organizational support, positive organizational behavior, and psychological ownership. Structural equation modeling using the bootstrap method was used to assess indirect effects to evaluate the model. The results indicated a strong fit between the model and the data, indicating significant direct effects of leader-member exchange, psychological ownership, and perceived organizational support on positive organizational behavior. Additionally, indirect effects through organizational self-esteem were confirmed. Based on the findings obtained from the validity of the model and the direct and indirect relationships, it is recommended to focus on the variables affecting positive organizational behavior.
