The Machiavellian Leadership: Scale Validity and Reliability Study

This study aims to develop a valid and reliable instrument, the Machiavellian Leadership Scale (MLS), designed to assess the extent to which educational leaders exhibit Machiavellian characteristics. In the research, the survey model was preferred in accordance with the objective of scale development. The scale has a structure that can be applied in all organizations. The sample of the research consists of administrators working in public and private schools in Istanbul. In the scale development process, first Exploratory Factor Analysis (EFA) and then Confirmatory Factor Analysis (CFA) were conducted within the scope of validity evaluation. EFA was conducted with 214 participants and CFA with 256 participants. As a result of the analyses, a scale consisting of four dimensions and 20 items was obtained. The sub-dimensions of the scale were named as protection, manipulation, strategic planning and power. Based on the results, the scale demonstrated a high level of internal consistency, indicating strong reliability. Additionally, the items showed significant discriminatory power in distinguishing between different levels of leadership behavior. These findings suggest that the Machiavellian Leadership Scale is a valid and reliable tool for assessing educational leadership within organizational settings. This result shows that the scale items have a high performance in terms of reliability and validity. As a result, it was decided that the scale was credible and consistent, and the scale was named as Machiavellian Leadership Scale (MLS).
