We explored related papers regarding the importance of communication in high-risk environments and those that considered communication as an influential factor [20; 21; 22; 23; 24]. The most similar work is [20], in which there were two similar properties: distributed teams and high-risk environments. It presented a concise work without mentioning any application domain or focusing on emergencies. The authors of [21] studied team communication and provided rich insights without a specific domain. Emphasis on adverse events was made by [22], who reviewed team resilience and proposed a multilevel model of workplace team resilience. Team resilience is related to our interest in emergency management since it supports a team in maintaining performance during adverse events and high-pressure environments. The authors of [23] found that communication was a useful team process in stressful situations and important in developing a common view of the situation, as part of the so-called \"team brain\". The authors of [24] identified 4 key variables associated with team function: leadership styles, supportive team behavior, communication, and performance feedback.  
Engineering team performance was reviewed by [25], and they found that the skillset/knowledge of team members had the highest impact on team performance. Although [25] discussed team performance during a general engineering project, we were more interested in their analysis of the team factor's impact on the team performance: positive, negative, or mixed impact. The healthcare domain dominated the research on teamwork in general as well as emergencies; however, most of their findings were highly domain-specific, such as physicians' non-technical skills, clinical performance, medical simulation, etc. [26; 27; 28].  
We found a paper that explored resilience in emergency management [29] and another that reviewed the Functional Resonance Analysis Method, which is an analysis method supporting resilience engineering [30]. Resilience is the capability to adapt one's reaction and performance, especially when facing unexpected situations. In handling NPP emergencies, we expect the operators working in teams to possess resilience; thus, we are inclined to apply resilience engineering principles. Cognition in crisis management teams is discussed by [31]. All the 11 constructs to define cognition were related to the collective sense of a team. A useful method for communication analysis was presented in [32]. In an attempt to find out how teams adapt their communications in critical situations, [32] compared team communication in critical and noncritical situations and analyzed the communication patterns using the Relational Event Model, a framework used in sociology, in which 7 types of communication patterns were defined.  
In summary, we found that no related study overlapped with the objective and content of our current study. Although [20] shared a few similarities, the covered literature was narrow, and the focus of their study was different. The other related studies either had a broader scope (team resilience, team performance), were on a different domain (general workspace, healthcare), or had a specified emphasis (stress, cognition). A team decision-making research study from 2021 [33] produced a list of associated and key factors affecting team decision-making performance and a conceptual model for organizing team decision-making performance factors. While in this paper, we used a similar research method, namely, listing the factors related to team communication and proposing a preliminary model of team communication by organizing the factors, the objective and emphasis of both studies are different. Moreover, in this paper, we performed a literature review using the PRISMA method and text mining; thus, we took more comprehensive steps.
