Introduction

The COVID-19 pandemic has put the world in a state of emergency. In addition to the impact of the virus itself, the World Health Organization (WHO) has raised concern over the impact of the societal changes associated with the pandemic – for example, social distancing, quarantine, lockdown and economic recession – on the mental health of the affected populations (WHO, 2020). We recently reported results from wave 1 of the COVID-19 Consequences Denmark Panel Survey 2020 (CCDPS 2020 – fielded from March 31 to April 6, 2020), which showed that (1) the level of psychological well-being as reported on the WHO five-item well-being scale [WHO-5 (Topp et al., Reference Topp, Ostergaard, Sondergaard and Bech2015)] was reduced compared to comparable data from the Danish Mental Health and Well-Being Survey 2016 (DMHWBS 2016) (Nielsen et al., Reference Nielsen, Hinrichsen, Santini and Koushede2017), and (2) that the level of psychological well-being correlated negatively with levels of self-reported symptoms of anxiety and depression (Sønderskov et al., Reference Sønderskov, Dinesen, Santini and Østergaard2020). These findings are consistent with those from studies of mental health from other countries and settings affected by the COVID-19 pandemic (Wang et al., Reference Wang, Pan, Wan, Tan, Xu, Mcintyre, Choo, Tran, Ho, Sharma and Ho2020, Vindegaard & Eriksen Benros, Reference Vindegaard and Eriksen Benros2020, Rohde et al., Reference Rohde, Hougaard Jefsen, Nørremark, Aalkjær Danielsen and Østergaard2020).

A pandemic is a dynamic phenomenon, and mental health of the affected populations is plausibly equally dynamic. To study this, we conducted a follow-up survey to gauge the mental health of the Danish population approximately 3 weeks after wave 1 of the CCDPS 2020. Here, we report the results from wave 2 of the CCDPS 2020 and compare them to those from wave 1.

Methods

We commissioned the survey agency Epinion, which undertook wave 1 of the CCDPS 2020, to conduct a follow-up survey (wave 2) targeting the same sample of people and containing the same questions pertaining to psychological well-being/distress [the WHO-5 and the six questions regarding the experienced level of anxiety/depression over the past 2 weeks reported on a scale from 0 (not present) to 10 (present to an extreme degree)]. Wave 2 was fielded from April 22 to April 30, 2020 and was completed by 2149 respondents who also had responded to wave 1 of the survey, resulting in a retention rate of 87.4% (2458 individuals responded to wave 1). After weighting (applied in all analyses), the sample is representative of the population on key demographic and political variables (gender, age, education, region and party choice in the last election).

We compared the following indicators of psychological well-being/distress in the two waves of the CCDPS 2020 survey: the WHO-5 scores (paired sample t-test) and reported symptom levels of anxiety/depression (paired sample t-test). Lastly, we also compared the scores on the WHO-5 in the second wave of the CCDPS 2020 with those from the DMHWBS 2016 (see Nielsen et al. (Reference Nielsen, Hinrichsen, Santini and Koushede2017) and the Supplementary Material in Sønderskov et al. (Reference Sønderskov, Dinesen, Santini and Østergaard2020) for a description).

Results

The mean age of the 2149 respondents who participated in both wave 1 and wave 2 in the CCDPS 2020 was 49.2 years and 51% were females. The mean WHO-5 score for these participants (see panel A in Fig. 1) was 62.1 for the total sample (64.8 for males and 59.5 for females) at wave 1 and 65.3 for the total sample (67.2 for males and 63.3 for females) at wave 2. This increase in self-reported well-being was statistically significant for the total sample (p < 0.001), for males (p < 0.001) and for females (p < 0.001). The mean scores on the self-reported anxiety/depression symptom items are shown in panel B in Fig. 1. There were statistically significant decreases from wave 1 to wave 2 on all symptoms except for feelings of guilt. The changes were most pronounced for worrying and feeling anxious. The WHO-5 scores at wave 2 were slightly higher than those from the DMHWBS 2016 (mean score: 64.3, 2-sided p-value for difference = 0.084).

Discussion

The main result of this study is that the psychological well-being of the Danish population seems to have increased from the first wave (March 31 to April 6, 2020) to the second wave (April 22 to April 30, 2020), possibly as a consequence of decreased symptoms of anxiety and depression. In support of this explanation, we found (post hoc) statistically significant negative correlations between changes in the level of each of the six anxiety/depression symptoms from wave 1 to wave 2 and changes in the WHO-5 scores from wave 1 to wave 2 (see the Supplementary Material). A main reason for this development may be the reduction in the spread of the coronavirus between the two waves of the survey and the associated societal response (see panel C in Fig. 1). Specifically, both the number of new COVID-19 cases (green curve in panel C) and the number of COVID-19 patients dying (grey bars in panel C) were markedly reduced from wave 1 to wave 2. The mean number of new COVID-19 cases/related deaths per day was 303/16 during wave 1 and 163/9 during wave 2. This progression was covered extensively in the news media and is therefore likely to be commonly known in the general population. In response to this development, the lockdown of the Danish society was gradually lifted between the two waves of the survey. Most notably perhaps, schools, kindergartens and other institutions, which had been closed from March 13, 2020, were gradually reopened on April 15, 2020. Many small businesses were allowed to reopen between the two survey waves as well. In other words, in the period separating the two surveys, the Danish society was slowly but safely approaching the pre-pandemic state, which is likely to have had a substantial positive impact on the mental health of the population.

In another two-wave survey of mental health/distress during the COVID-19 pandemic, Wang et al. (Reference Wang, Pan, Wan, Tan, Xu, Mcintyre, Choo, Tran, Ho, Sharma and Ho2020) found no differences in the levels of stress, anxiety and depression in the Chinese population from wave 1 (31st January to 2nd February – shortly after the initial outbreak in China) to wave 2 (28th February to 1st March – approximately at the apex of the pandemic in China). However, this survey used snowball sampling (population representation unclear) and the two waves consisted of (partly) different respondents, making it hard to draw any valid inferences regarding the development in well-being.

In conclusion, while we can by no means claim causality, the results of our study are intuitively compatible with psychological well-being, co-varying with the intensity of the COVID-19 pandemic and the associated societal restrictions. Valid longitudinal data on the mental health of populations that have been more severely affected by the COVID-19 pandemic than has been the case in Denmark are urgently needed.
