Police are required to operate in complex social, political, and organizational environments. Nowadays, challenging times highlight the role that police leaders play in ensuring that the organization is effective in dealing with such environments. The purpose of this paper is to expand the systematic review of literature of Pearson-Goff and Herrington (2014, ‘Police Leadership: A Systematic Review of the Literature.’ Policing: A Journal of Policy and Practice 8(1): 14–26) by: (1) including studies after the date considered by the authors; (2) following the PRISMA-P approach to systematic reviews; and (3) include European studies. Based on 7,041 records, which ended up in 101 eligible empirical pieces, evidence supports previous findings about what are the characteristics of police leaders as well as the actions expected by them. This comprehensive systematic review also identifies additional characteristics and actions that are important nowadays in police leadership. Overall, the current study encourages future studies on the thematic, and contributes to practitioners aiming to develop continuous improvement strategies inside the police.

Based on emotional labor theory, we aim to study the relationships between the dimensions of emotional labor (requirements and strategies), work engagement, and occupational identity in Portuguese police officers. Therefore, we intend to explore the possible effects of emotional labor both on work engagement and occupational identity, as well as ways of preventing and/or mitigating the impact of these relationships. We identified a gap in the studies on this subject in Portugal, particularly in the context of police professionals. Thus, a sample of 924 Portuguese police officers of the Public Security Police (PSP) was asked to answer a set of questionnaires: the Emotional Labour Scale, the Emotion Work Requirements Scale, the Utrecht Work Engagement Scale, and the Social Identity Scale. The data obtained was analyzed using correlation and multiple linear regression. Overall, the results revealed relationships between the emotional demands (i.e., suppression of negative emotions and expression of positive emotions) and strategies (i.e., deep and surface acting) of emotional labor and work engagement as well as occupational identity. We discuss these results and propose directions for future research, given the richness of the subject.

Grounded in the Emotional Labour Theory, we aim to study the relationship between emotional demands (the expression of positive emotions and suppression of negative emotions) and work engagement in a sample of Portuguese police officers. We intend to explore the possible effects of these emotional demands on work engagement and ways of preventing and/or mitigating its impact. When analysing the studies conducted in the Portuguese police context, we found a gap regarding emotions and/or emotional regulation. Accordingly, a sample of 924 Portuguese police officers from the Public Security Police (PSP) answered the Emotion Work Requirements Scale and the Utrecht Work Engagement Scale voluntarily. Through correlation and multiple linear regression, we found a relationship between these emotional demands toward different interpersonal interactions and work engagement. We discuss these results, providing suggestions for field intervention and clues for future research.

In public security policing, where pressure is constant, effective decision-making and emotion regulation are critical, especially for leaders. These processes significantly impact upon work results, performance, officials’ health, employee well-being, and the organizational environment. This study aims to broaden the understanding of decision-making styles and emotion-regulation strategies used by police officials in the Portuguese Public Security Police (PSP). We surveyed 138 Portuguese high-ranking police officials using two self-response questionnaires, namely the Emotion Regulation in the Workplace (ReTrab) and the Melbourne Decision Making Questionnaire (MDMQ), both translated, adapted, and validated for the Portuguese police context. A confirmatory factor analysis was conducted, followed by correlations to explore the relationship between emotion-regulation strategies and decision-making styles. Finally, through a regression analysis, the potential impact of this relationship was assessed. The results reveal that specific emotion-regulation strategies, except for adaptive ones, significantly influence and modify the decision-making styles of PSP officials. Dysfunctional and maladaptive emotion-regulation strategies lead to less adaptive decision-making styles, while functional strategies promote more adaptive styles. These findings have theoretical and practical implications, offering valuable insights for targeted training programs and interventions in the law-enforcement sector, benefiting the police personnel, the communities they serve, and public perceptions about police.
