- The impact of leadership on information overload and stress : exploring the mediating role of sense of powerPublication . Henriques, Marta Maria Veiga Cardiga; Almeida, Filipa deThis dissertation aims to explore the influence of different organisational positions on perceived information overload and stress. Could this relationship be explained by the sense of power? The information overload phenomenon occurs when the capacity to process information is lower than the information being received, meaning that the high load of information becomes a limitation rather than a support to an ideal decision-making process. Indeed, the constant disruptive technological advancements have been contributing to the growing availability of information. Consequently, there is an increasing necessity to address this phenomenon since it negatively affects productivity, decision-making and stress. Furthermore, previous findings have indicated that an enhanced sense of power, closely tied to leadership positions, enables more effective information processing capacities. On that basis, the results in this study have demonstrated alignment with previous research since it concludes that the sense of power effectively explains how leaders perceive less information overload. Moreover, power acts as an essential mechanism between information overload perceptions and organisational positions, mitigating adverse organisational outcomes, such as stress. In sum, this dissertation offers a novel perspective on how leadership and power influence cognitive organisational challenges. It refers to the perspective of power as a protective factor against information overload and stress perceptions, offering meaningful insights for both managerial practices and academic research.
