The psychological impact of the COVID-19 pandemic on Dutch people with and without an inflammatory rheumatic disease

Abstract

Objectives

To determine the psychological impact of the COVID-19 pandemic on people with and without an inflammatory rheumatic disease and establish whether psychological flexibility buffers this impact.

Methods

From online surveys in the general Dutch population in 2018 and during the peak of the COVID-19 pandemic in 2020, we analysed data of people with (index group, n = 239) and without (control group, n = 1821) an inflammatory rheumatic disease. Worry, stress, mental well-being (SF-36) and psychological flexibility levels were subjected to covariate-adjusted analyses of variance or linear regression analyses.

Results

During the peak of the COVID-19 pandemic in 2020, as compared with the control group, the index group was more worried about getting infected with the virus (partial η²=0.098; medium effect) and more stressed (partial η²= 0.040; small effect). However, as compared with data acquired in 2018, the level of mental well-being during the COVID-19 pandemic peak was not lower in both groups. Levels of psychological flexibility did not moderate associations of group or year with mental well-being.

Conclusions

Although patients with an inflammatory rheumatic disease were more worried and stressed during the peak of the COVID-19 pandemic, their level of mental well-being was not reduced, which may have prevented us from finding a buffering effect of psychological flexibility. Overall, our results suggest that the psychological impact of the COVID-19 pandemic in patients with inflammatory rheumatic disease is modest, which could imply that common education and health care will do for most patients.
