A study by Zhenyu Li et al. evaluated vicarious traumatization scores among 214 members of the general public and 526 nurses (234 front-line and 292 non-front-line) using a mobile app-based questionnaire. The results showed that front-line nurses had significantly lower vicarious traumatization scores compared to non-front-line nurses (P < 0.001), while the general public had significantly higher scores than front-line nurses (P < 0.001) but not significantly different from non-front-line nurses (P > 0.05). The study highlights the need for increased attention to the psychological well-being of medical staff, especially non-front-line nurses, and the general public during the COVID-19 pandemic. Early interventions to prevent and treat vicarious traumatization are crucial. The study used a mobile app-based questionnaire survey conducted from February 17 to 21, 2020, with 740 participants (526 nurses and 214 general public). The vicarious traumatization questionnaire, adapted from existing scales, assessed physiological and psychological responses. Statistical analyses revealed significant differences in vicarious traumatization scores among the groups, with front-line nurses having the lowest scores and non-front-line nurses showing more severe symptoms. The study emphasizes the importance of early intervention and transparent information dissemination to support the psychological well-being of all affected individuals.The COVID-19 Resource Centre, established by Elsevier in January 2020, provides free information in English and Mandarin on the novel coronavirus.
