In recent years, the stress caused by the Covid-19 Pandemic has increased on the stress of working in difficult jobs, in this research resilience and coping styles focus on responding to stress. The present study aimed to examine the effect of resilience training on coping strategies during the COVID-19 pandemic by holding resilience-training sessions. Method: This is a quasi-experimental study with a pretest-posttest control group design. The statistical population included all married personnel of Kavir Steel Complex, Aran and Bidgol County. In total, 30 couples were randomly selected and divided into case and control groups (n = 15 couples per group). In this study, Henderson and Milstein's resilience training package was used for resilience training; two basic assumptions of variance homogeneity of posttest error of coping strategies and homogeneity of regression line slope between pretests and posttests were examined. For data analyzing, we used SPSS Version 25. Results: The results showed resilience training increased application of problem-oriented coping strategies (p , .01, SE = 1.88, Dx = 10.19) and decreased application of emotion-oriented (p , .01, SE = 1.69, Dx = 8.65) and avoidance (p , .01, SE = 1.86, Dx = 4.15) coping strategies among the personnel. Moreover, the interaction effect of group and gender was only significant on emotion-oriented strategies at .05 (p , .05, F = 6.51). Conclusions: Analyzing the results showed that problem-oriented coping strategies, in contrast to avoidant and emotion-oriented strategies, positively controlled stress. The ability to deal with stressors is critical to daily functioning, adaptation, and mental and physical health. Clinical Impact StatementResilience is the hallmark of successful people and successful companies, and it is what allows people to come back from disappointment and failure stronger and more determined than ever. Resilience is something that can be learned and developed by anyone. In the present study, resilience training increased using problem-oriented coping strategies and decreased using avoidance and emotion-oriented strategies.
