Researchers are increasingly conducting research using primary source data involving observation of, and exposure to, violent extremist individuals, their acts, their online content, and the ideologies that they act in support of. Of concern is that this increased use of primary source material has not occurred alongside a serious investigation of the traumatic outcomes that may result from constant exposure to such materials within the process of conducting academic research. As such, the goal of this review is to conduct a rapid evidence assessment to identify (a) What theories currently exist that conceptualize trauma stemming from vicarious observation of extremist atrocities? (b) In what similar domains (if any) have researchers conceptualized the trauma that stems from vicarious observation of extremist atrocities? (c) What is the current evidence base for these theories? And (d) What are the immediate research needs to extend this research and support the research workforce? Articles were identified using search strings related to types of trauma, and relevant domains of work (e.g., criminal justice, healthcare, national security, content moderation). In total 34 articles were screened and assessed in full. The work domains of these articles ranged from drone warfare to digital forensics and interrogation interpreters. Overall, exposure to traumatic images, videos, and events is associated with burnout, secondary traumatic stress, turnover intentions, and a host of wider negative psychosocial outcomes. Furthermore, this process is impacted by several factors including the nature of the content, the wider organizational culture, and individual differences.
