Servant Leadership Behaviour Scale: A hierarchical model and test of construct validity

Servant leadership is widely believed to be a multidimensional construct. However, existing measures of servant leadership typically suffer from highly correlated dimensions, raising concerns over discriminant validity. We set out in this study to examine the dimensionality of the hypothesized six-factor Servant Leadership Behaviour Scale (SLBS) and validate a hierarchical model of servant leadership. Using structural equation modelling, convergent and discriminant validity of the higher-order servant leadership construct was examined in relation to measures of character-related behaviour, Machiavellian leadership orientation, and social desirability. Our findings suggest that the SLBS assesses a single, higher-order construct of servant leadership with evidence of construct validity and absence of social desirability bias. The high correlation between servant leadership and character-related behaviour supports our expectation that servant leadership reflects in large part the character strength of the leader.     

Morality and Leadership: Examining the Ethics of Transformational Leadership

Morality is a critical factor in leadership that its absence could turn an otherwise powerful leadership model (i.e. transformational leadership) into a disastrous outcome. The importance of morality for leaders is self-evident in light of the far-reaching effects of leaders' actions or inaction on other people. Such proposition necessitates the discourse in the objectivity of universal moral principles as the legitimate basis of a sound understanding of moral leadership. Examining transformational leadership from a moral-laden perspective, this paper argues that morality is a necessary component of leadership and that deontological moral reasoning provides a sufficient ground for morally attractive leadership theories.
