Development and Psychometric Evaluation of the Questionnaire of Ethical Leadership (QueL)
Abstract
Abstract. In this five-study paper, we developed and validated the Questionnaire of ethical Leadership (QueL). We examined the factor structure of QueL using Exploratory and Confirmatory Factor Analysis, along with measurement invariance techniques, using data from more than 1,200 leaders and subordinates working in Greece. Exploratory analysis indicated two latent highly-correlated factors that were labeled “Telos” and “Ethos.” Confirmatory analysis verified a bifactor solution. The bifactor QueL showed configural, metric, and scalar invariance across independent samples of leaders and subordinates. QueL was found to be a reliable measure across time and occupational groups (leaders and subordinates). We found criterion correlations in the expected direction with other ethical leadership scales, related constructs (i.e., integrity, trust, ethical climate), as well as workplace attitudes and behaviors (i.e., burnout, organizational commitment, organizational citizenship behaviors, deviant behaviors), leadership characteristics (transformational and transactional leadership, abusive supervision, personality), and socio-demographics (i.e., educational level and gender). We conclude that the new measure is a valuable tool for measuring workplace ethical leadership.
