Abstract

Emergency teams facing critical adversity situations often feel questioned in their professional roles as conscientious rescuers, leading to feelings of threats as a kind of stress experience. According to the stress-as-offence-to-self theory, perceptions of insufficiency and disrespect trigger threats by frustrating underlying needs. In this study, we explored threats in the context of a CAS by investigating the activation of threat triggers during the action and postaction phases of teamwork, and evaluating the mediating role of needs. In a multitask experiment, student teams experienced a controllable mission, followed by a CAS mission in a computer simulation task. After the CAS, teams received negative feedback. We measured threats, the activation of insufficiency and disrespect triggers, and the frustration of needs. While insufficiency triggers were activated in the CAS but not in the non-CAS, disrespect triggers were activated by situation-nonspecific and situation-specific feedback but not by no feedback. Furthermore, the results of mediation models indicated the presence of the postulated need-based mechanism between triggers and threats. Our study highlights that the action and postaction phases of a CAS pose a variety of risks for experiencing threats. As individuals cope with these risks, needs are important mediators.
