– The purpose of this paper is to address the question of what motivates leaders to engage in effective leadership behaviours by integrating transformational leadership theory and self-determination theory. The authors propose that the type of enacted leadership behaviour is related to level of self-determined motivation.
– This study presents validity evidence for an 18-item scale of motivation for transformational leadership based on Gagné and Deci’s (2005) six levels of internalization. A total of 310 employees (mean age=39, 64.5 per cent female, 46 per cent formal leaders) completed the scale, other measures of leadership, and job satisfaction.
– Results supported the theorized six-factor structure of the scale and provided evidence for incremental validity in the prediction of job satisfaction and transformational leadership above and beyond another measure of motivation to lead.
– The lack of amotivation and the presence of autonomously controlled extrinsic motivation are predictive of effective leadership behaviour, a key finding with implications for leadership selection. The study was limited by the use of self-report data. Future studies should examine additional predictors and outcomes of the construct (e.g. subordinate attitudes or performance and leader personality), and whether it is stable over time.
– Leaders’ motivation for role effectiveness is an unexplored area of research. This study suggests that type of motivation can be important for effective leadership and provides a validated scale for use in future leadership research and selection.
