Background/Purpose: The examination of decision-making styles (DMS) is crucial for understanding how individuals approach choices and form preferences. Two influential frameworks in the DMS discourse, proposed by Scott & Bruce, and Rowe, provide insightful lenses for correlating dominant styles with an array of personal characteristics. Methods: This comprehensive study delves into questionnaire results obtained in 2020 and 2022, employing methodologies aligned with Scott & Bruce, and Rowe. The survey targeted cohorts of business and military students, capturing nuanced aspects of decision-making. Introducing innovative concepts, namely submissive DMS and intensity of influence, expanded the analytical framework and facilitated a deeper understanding of decision-making dynamics. Results: The analysis revealed substantial variations in decision-making styles within student populations, elucidating correlations with distinct personal characteristics. The incorporation of the intensity of dominance concept allowed for nuanced interpretations, particularly during the challenging COVID-19 period and the subsequent return to normalcy. Conclusion: The integration of proposed concepts represents a significant enrichment for future research in the field of DMS. This study underscores the critical role of evolving methodologies in elucidating the intricacies of decision-making processes. The ongoing refinement of these methodologies promises a more nuanced understanding of how individuals navigate complex decision-making scenarios.
