This dissertation emphasizes the importance of the human factor in the organizational change process. Change - the only constant - is inevitable for organizations and no change program can be achieved without the support and acceptance of organization members. In this context, this study identifies officer attitudes toward organizational change in the Turkish National Police (TNP) and the factors affecting those attitudes. The Officer Attitude Model created by the researcher includes six main factors (receptivity to change, readiness for change, trust in management, commitment to organization, communication of change, and training for change) and five background factors (gender, age, rank, level of education, and work experience) to explain officer attitudes toward change. In order to test this model, an officer attitude survey was administered in Turkey among TNP members and the results of the gathered data validated this model.
