Three Dimensional Leader-Member Exchange Scale (LMX-3D): A Scale Development Study

The aim of this study is to develop a valid and reliable measurement tool to measuring teachers’ leader-member exchange behaviors. The study group of the research consists of 396 teachers working in secondary schools in the central districts of Eskişehir, Odunpazarı and Tepebaşı, in the 2018-2019 academic year. The construct validity of the scale was examined by exploratory factor analysis. According to the results of the analysis, the scale measures a three-factor structure. It was also confirmed by confirmatory factor analysis that the scale measures the three-factor structure. The total variance rate explained by the scale was determined as 67,72%. In order to determine the reliability of the scale, the Cronbach Alpha internal consistency coefficient value was checked and this value was determined as 0.922. The results of all validity and reliability analyzes show that the Three Dimensional Leader-Member Exchange Scale (LMX-3D) can be used as a valid and reliable measurement tool in the studies that teachers will be taken as a working group.
