The principled leadership scale: An integration of value-based leadership

Abstract

Orientation: A need exists to investigate leader behaviour necessary to curb the corruption that has infected and weakened South Africa’s moral fibre. Such leader behaviour would need to be underpinned by a set of universal moral values. Research purpose: The purpose of this study was to develop a new measure, the principled leadership scale (PLS), by integrating the value-based behaviours inherent in transformational, servant, authentic and ethical leadership. Motivation for the study: Leader behaviour intrinsic to value-based leadership was found to be closely aligned with universal moral values. Because the study found a considerable overlap between the behaviours mentioned in the value-based leadership theories, it sought to integrate these behaviours under one construct and to develop a reliable and valid scale to assess this construct. Research approach/design and method: Data from the quantitative study were analysed by means of item analysis, exploratory and confirmatory bi-factor analysis conducted via structural equation modelling. Main findings: The confirmatory bi-factor solution corroborated a strong general principled leadership factor and four moderately weak group factors. The statistical analyses provided good fit of the PLS measurement model with the empirical data. Practical and managerial implications: The study found acceptable measurement properties of the PLS that may be used for applications, such as the selecting, training and developing of ethical leadership in organisations. Contribution/value-add: The study adds value in that it is the first to integrate the four value-based leadership theories under one construct and to develop a potential psychometrically sound instrument to measure principled leadership.
