Leadership in police work applied to critical contexts: An integrative review and scientific mapping using VOSviewer and Google Trends tools

The aim of this study is to identify cutting-edge studies on the phenomenon of leadership applied to police work, especially in critical contexts, based on an integrative literature review. The integrative review made it possible to survey publications on the subject in the Scopus, Web of Science, Ebsco Host, ScienceDirect, Core, and SciELO databases. Scientific mapping is complemented with the use of VOSviewer and Google Trends tools. The integrative review resulted in 15 studies that fit the research strategy, bringing different leadership approaches, such as instrumental, transformational, charismatic, consultative, ethical, authentic, military, destructive, and laissez-faire, through qualitative and/or quantitative studies. For bibliometric analysis using VOSviewer, the research corpus was expanded to 63 articles, admitting documents that studied leadership with firefighters, military personnel, and police officers. The analysis showed almost no co-authorship link between the 129 authors. The co-occurrence analysis of keywords reveals that leadership strongly links with law enforcement, police, management, crisis management, emergency management, and decision-making, establishing a close relationship between these concepts and a semantic map that underlies the field of study. The analysis of trends by Google Trends in the science category indicates the stability of interest in the topic of leadership in the world. However, the theme of police leadership produced results close to zero. The findings reveal that few studies address leadership in police organisations, and even fewer if critical, dangerous contexts are examined. The trends analysed indicate that worldwide scientific interest in the subject remains low and the theme must be further explored.
