Investigating the mediating influence of distress tolerance on the relationship between existential thinking, sense of coherence, and the severity of mourning among families who lost a loved one to COVID-19: A cross-sectional study.

Background And Aims: The objective of the current study was to examine how distress tolerance functions as a mediator in the relationship between existential thinking, sense of coherence, and the severity of mourning experienced by families who have lost a loved one to COVID-19.

Methods: The present study employed a descriptive correlational research design, targeting family members of those who passed away due to COVID-19 in the city of Mianeh in 2022. A sample of 160 individuals was selected for statistical analysis. The research instruments used in this study consisted of Flensberg's sense of coherence questionnaire (2006), Simmons and Gaher's emotional distress tolerance questionnaire (2005), Sugbart and Scott's grief experience questionnaire (1989), and Branton Scherer's existential thinking questionnaire (2006). The collected data were analyzed using path analysis, as well as SPSS and Amos software.

Results: The findings of the study revealed a significant correlation coefficient between existential thinking ( = 0.465), sense of coherence ( = 0.401), and distress tolerance ( = 0.521) with the severity of mourning experienced by families who lost a loved one to COVID-19. Moreover, the results indicated a positive and significant relationship ( > 0.01) between distress tolerance and sense of coherence ( = 0.126), as well as between distress tolerance and existential thinking ( = 0.059) among the bereaved families. However, the bootstrap test results suggested that distress tolerance did not mediate the relationship between sense of coherence and the severity of mourning in the families of COVID-19 victims.

Conclusion: Consistent with prior research, the current study's findings indicated that both existential thinking and sense of coherence had a direct impact on the severity of mourning experienced by families who lost a loved one to COVID-19. Additionally, the results revealed that the influence of existential thinking on the severity of mourning was mediated indirectly by increasing distress tolerance.
