Relationship between intolerance of uncertainty and symptom severity in Covid-19 patients: the mediating role of illness perception and Covid-19 fear

The dynamic nature of coronavirus-19 (Covid-19) has caused a wreaked havoc globally, with millions of confirmed cases and deaths. Therefore, it is important to understand the psychological impact of the Covid-19 on the patients. In the present study, we examine whether intolerance of uncertainty was related to the severity of symptoms and whether this relationship is mediated by perception of illness and covid-19 fear. The study sample comprised of 98 Covid-19 patients (Mean = 35.17 SD = 12.89). Mediation analysis was conducted using the PROCESS macro for SPSS. Results of mediation analysis showed that the direct effect of intolerance of uncertainty on symptom severity was insignificant. However, the indirect effect via illness perception was significant, reflecting full mediation. The findings add knowledge to our understanding of the psychological consequences of Covid-19. The present study has implications for mental health services for patients with Covid-19, which will play a vital role in recovery from the illness.
