Contribution of rumination and psychological resilience to post-traumatic growth of front-line healthcare workers in mobile cabin hospitals under Normalized epidemic Prevention and Control Requirements

To understand the level of post-traumatic growth (PTG) and influencing factors among front-line healthcare workers (HCWs) working in mobile cabin hospitals treating patients with Coronavirus Disease 2019 (COVID-19) under the Normalized Epidemic Prevention and Control Requirements adopted in China. A random sampling method was used to select 540 HCWs of the Chongqing-aid-Shanghai medical team from April to May 2022 as the study participants. Participants completed a general information questionnaire, the Post-traumatic Growth Inventory-Chinese version (PTGI-C), the Chinese version of the Connor-Davidson Resilience Scale (CD-RISC) and the Chinese Event Related Rumination Inventory (C-ERRI). Among the 540 included HCWs, 83.15 % were nurses and 78.89 % were women. The average scores for PTG (62.25 +/- 16.73) and psychological resilience (64.22 +/- 15.38) were at moderate levels, and the average score for rumination was low (21.62 +/- 10.77). Pearson cor-relation analysis showed that CD-RISC and C-ERRI scores were positive with the PTGI-C score (r = 0.528, 0.316, P < 0.001). Multiple linear regression analysis identified psychological training or intervention during the COVID-19 epidemic (beta = 2.353, P = 0.044), psychological resilience (beta = 0.525, P < 0.001) and deliberate rumination (beta = 0.732, P < 0.001) as factors significantly associated with the PTG of front-line HCWs, which together explained 36.8 % of the total variance in PTG (F[5,539] = 63.866, P < 0.001). In general, psychological resilience and deliberate rumination can promote PTG among HCWs and can be improved by strengthening psychological training and interventions for HCWs working under the Normalized Epidemic Prevention and Control Requirements.
