Transformational leadership sub-dimensions and their link to leaders' personality and performance

The multi-dimensionality of the transformational leadership construct has been under debate in the last decades. To shed more light on this issue, we conducted a meta-analysis (k = 58 studies), examining the transformational leadership sub-dimensions and their links to leader personality and performance in order to gather empirical evidence of the multi-dimensionality of transformational leadership. First, the results showed that the Big 5 personality traits are directly linked to transformational leadership sub-dimensions and to the overall measure, and are indirectly linked to leader performance. Interestingly, however, different combinations of the personality traits are differentially related to the transformational leadership behaviors. For instance, whereas inspirational motivation is related to all personality traits, only openness to experience and agreeableness affect individualized consideration. These findings emphasize the importance of examining the transformational leadership sub-dimensions separately to gain a deeper understanding of the nature and the antecedents of these leadership behaviors.
