Turkish Adaptation of Toxic Leadership Scale: Validity and Reliability Study

Abstract

One of the most referenced and generally accepted scales used in the literature to measure the perception of 'toxic leadership' is the Toxic Leadership Scale prepared by Schmidt. In Schmidt’s scale, it was assumed that the toxic leader had five characteristics: abusive, authoritarianism, narcissism, self-promotion, and unpredictability, and a 30-item scale was created to measure these five factors. In our study, the scale prepared by Schmidt was adapted into Turkish. The questions prepared with the obtained scale were applied to 676 people in two separate samples, 392 public sector employees and 284 private sector employees. As a result of all reliability and validity analyses the Toxic Leadership Scale was adapted into Turkish and could be used as a measurement tool.
