Mediation analysis exploring the relationship among resilience, PTSD, and somatization. c’, direct effect; c, total effect; (a*b), indirect effect. After monitoring the effects of covariates (age, sex, educational qualification, income, marital status, staff, title, years of work, worksite, work content, provision of support to Hubei in 2019, work schedule/week, ways of COVID-19-related work, training, competence in position, mental support, frequency of contact with family and friends, and psychological support from family and friends), the analysis of mediation models showed that the total effect of resilience on PTSD and somatization remained significant (PTSD: c = -0.433, p < 0.001; somatization: c = -0.170, p < 0.001). The direct effect (c’) of resilience associated with the mediator (PTSD: c’ = -0.086; somatization: c’ = -0.030) was altered but remained insignificant after controlling the variance. These results suggest that perceived stress mainly mediates the association between PTSD and somatization through resilience.
