“…Firstly, a long-standing debate regarding the conceptual overlap and potential redundancy of the SL construct with related leadership constructs (e.g., transformational, ethical, authentic: Antonakis, Ashkanasy, & Dasborough, 2009;Banks, McCauley, Gardner, & Guler, 2016) continues to plague the literature (Lemoine et al, 2019). Indeed, findings from a recent meta-analysis on leadership behaviours (Banks, Gooty, Ross, Williams, & Harrington, 2018) suggest large correlations between SL and transformational leadership (TL) (r = .52; k = 5), as well as other morally based leadership approaches, namely authentic leadership (AL; e.g., Avolio & Gardner, 2005; r = .60; k = 1) and ethical leadership (EL; e.g., Brown, Treviño, & Harrison, 2005; r = .81; k = 1), although it should be noted that these results were based on very few (often single) studies. Furthermore, while Hoch, Bommer, Dulebohn, and Wu (2018) did find metaanalytic evidence of the incremental predictive validity of SL over TL, its incremental predictive validity over AL and EL is yet to be empirically established.…”
