Ethische Führung – Gütekriterien einer deutschen Adaptation der Ethical Leadership Scale (ELS-D) von
Abstract
Ziel des vorliegenden Beitrages ist, die Gütekriterien eines Instruments zur Erfassung von ethischer Führung zu überprüfen. Ausgangspunkt war die Übersetzung der Ethical Leadership Scale von Brown, Trevino und Harrison (2005) ins Deutsche (ELS-D). Anschließend wurde anhand dreier Stichproben (N1 = 100, N2 = 119, N3 = 507) die faktorielle Binnenstruktur des Instrumentes überprüft. Es ergaben sich zwei Faktoren (ethische Mitarbeiterführung und ethisches Rollenmodell). Es zeigten sich konvergente Validitäten zwischen den Skalen ethischer Führung und transformationaler, transaktionaler, mitarbeiter- und aufgabenorientierter Führung (positive Korrelationen) sowie Laissez-faire (negative Korrelation). Demgegenüber waren die Skalen ethischer Führung erwartungskonform überwiegend unabhängig vom Alter der geführten Mitarbeiter und vom Geschlecht der Führungskraft. Hohe Zusammenhänge zwischen ethischer Führung und der Arbeitszufriedenheit sowie dem Commitment der Mitarbeiter werden als Belege für die Konstruktvalidität gewertet. Die interne Konsistenz der ELS-D-Skalen war in allen drei empirischen Studien gut. Insgesamt steht mit der hier vorgestellten deutschen Adaptation der ELS ein ökonomisches Instrument mit ansprechenden Gütekriterien für den Einsatz bereit.
The aim of the present paper was to test the psychometric properties of an instrument for the assessment of ethical leadership. The vantage point was the translation of the ethical leadership scale of Brown, Trevino, and Harrison (2005) into the German language (ELS-D). Subsequently, based on three samples (N1 = 100, N2 = 119, N3 = 507), the factorial structure of the instrument was tested. Two factors emerged (ethical leadership and ethical role modeling). Convergent validities between scales of ethical leadership and transformational leadership, transactional leadership, consideration and initiating structure (positive correlations) as well as laissez-faire (negative correlation) became evident. On the other hand, and as expected, scales of ethical leadership were predominantly independent of followersʼ age and leadersʼ gender. Close relationships between scales of ethical leadership and followersʼ job satisfaction and commitment were interpreted as evidence for construct validity. The internal consistencies of the ELS-D scales were good for all three empirical studies. In sum, with this German version of the ELS, an economic instrument with good psychometric properties is available.
