Exploring the Relationship between Decision-Making Styles and Emotion Regulation: A Study of Police Officials in Portuguese Public Security

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.
