Review of leadership, leadership styles and measurement models over the last decade

In this paper, a bibliometric and documentary analysis of leadership, leadership styles and leadership methods of identification in companies over the last decade was carried out. To this end, a systematic review of scientific publications contained in Scopus databases between 2009 and 2019 was performed. The search engines of the National Library System of the National University of Colombia and Google Scholar were used to retrieve the publications. A total of 950 scientific papers were reviewed for the bibliometric analysis. As a result of this analysis, different leadership styles were identified, the number of which varied depending both on the author and on the identification method. The study concludes that the transformational leadership style prevails in the scientific literature. In addition, the analysis found that the Multifactorial Leadership Questionnaire (MLQ) is the instrument that allows identifying in greater depth the leadership style characteristics.
