Abstract: Change is an essentialaspect for the organization to enable employees to learn new skills andexplore new opportunities, which ultimately benefit the organization. One crucialelement in change management is the readiness of the organization to change or the readiness to change.This study aims to determine the effect and the dimensions of change valence, which have the most substantialinfluence on readiness to change.This studywas conducted at one private hospital that planned to change the typeof its hospital into a teaching hospital. This studywas classified asan observational analytic with a cross-sectional research design. The study samples were chosen randomly utilizinga proportional random sampling technique. Retrieval of research related data employeda questionnaire that had been tested for its validity and reliability.The results indicatedthat change valence influencedthe readiness to change based on statistical tests using simple linear regression (R = 0.726 and R2 = 0.527). The strongest dimension that influencedthe readiness to change was Perceived Appropriateness (R = 0.529 and R2 = 0.280).The higher the change valence, the higher the level of organizational readiness to change. A critical dimension of change valence was the Perceived Appropriateness dimension. Therefore,if the organization plans to increase its readiness to change, the management should consider the perceivedappropriateness dimension more than any other aspects.
