“…Of all domains under study, we found that health-related stressful experiences were consistently the ones with the strongest association with all three operationalizations of TSS in time (i.e., prevalence, incidence and persistence). This is in line with previous studies using cross-sectional study designs that found that traumatic stress was associated with fear of infecting others (Bayazit et al, 2022;Billings et al, 2021;Greene et al, 2020;Norful et al, 2021), having family members infected (Al Falasi et al, 2021;Blanco-Daza et al, 2022), stress over one's own health and feeling little control over getting infected (Annaloro et al, 2021;Blanco-Daza et al, 2022;Johnson et al, 2020;Luce ñ o-Moreno et al, 2020;Ouyang et al, 2022;Si et al, 2020). We confirm these previous findings, and our study now suggests that healthrelated stressful experiences were also associated with delayed onset as well as persistence of TSS among HCW following the first COVID-19 outbreak in Spain.…”
