The study included 421 samples from administrative organizations. During the study, data were collected using a questionnaire and then tested and verified using SEM and linear regression analysis. Leadership behavior exerted a positive effect on organizational efficacy, and conflict management had a mediating effect on the relationship between leadership behavior and organizational efficacy. The study showed that conflict management was an appropriate intermediary variable. Efficient leadership behavior resulted in improved organizational efficacy. Conflict management may positively influence organizational efficacy.
