What factors contribute to maintaining mental well-being during the COVID-19 pandemic?

Background

The COVID-19 pandemic posed numerous challenges for many people and first results indicate high variability of responses in mental well-being. Thus, this research aimed to identify longitudinal factors contributing to the maintenance of mental well-being despite the adverse life circumstances and derive recommendations suitable for the promotion of mental well-being in the context of future pandemic or similar stressful situations.

Methods

We analysed representative longitudinal panel data of the Socio-Economic Panel (SOEP) from 15,122 adults (age range 18-99 years) who participated in the collaborative SOEP-CoV and RKI-SOEP surveys comprising self-reports of mental well-being (e.g., life satisfaction) and potentially relevant factors (e.g., control beliefs). By taking data from before (2015-2019) and during the COVID-19 pandemic (2020-2021) into account, we investigated different patterns of mental well-being trajectories and factors associated with the maintenance of mental well-being over time.

Results

Preliminary results suggest that the majority of adults in Germany managed to maintain or even enhance their mental well-being in the considered time frame. Moreover, results suggest that certain factors seem to be of universal importance (e.g., altruism, locus of control) while others are particularly relevant for distinct mental well-being dimensions (e.g., life goals). Most decisively, the probability of experiencing mental well-being deterioration during the COVID-19 pandemic was enhanced in individuals with an internal locus of control.

Conclusions

The findings revealed longitudinal factors that contribute to maintaining mental well-being during the COVID-19 pandemic. Promoting altruism, family-related life goals and external locus of control beliefs can help fostering resilient responses in the face of challenging life events such as the COVID-19 pandemic.

Key messages

• Several factors (e.g., locus of control) offer the potential to maintain or even improve mental well-being in times characterized by the COVID-19 pandemic.

• To enhance preparedness for stressful life events such as the COVID-19 pandemic, the identified key factors should be included in basic universal public health promotion.

SARS-CoV-2 Seroprevalence in Germany: results from the second wave of the RKI-SOEP study

Introduction

The first wave of the “Corona Monitoring bundesweit” (RKI-SOEP) study showed that shortly before the start of the German vaccination program only about 2% of adults (> 18 years) had already experienced SARS-CoV-2 infection and more than half of these cases had been detected and notified. The objectives of the second wave of this study are to further investigate the spread of SARS-CoV-2 in Germanýs population aged over 14 years. It aims to determine the seroprevalence of infection- and vaccine-induced IgG antibodies against SARS-CoV-2. Finally, it examines health, demographic and socioeconomic risk and protective factors for infection and vaccine acceptance.

Methods

From November 2021 to February 2022, the second wave of this cross-sectional study collected biospecimens (capillary blood samples) and interview data, including information on infection and vaccination, from a nationwide population sample drawn from the German Socio-Economic Panel (SOEP). The dried self-collected blood samples were then analyzed for the detection of SARS-CoV-2 IgG antibodies by Euroimmun ELISA assay.

Results

Based on preliminary, unweighted data of around 11,000 participants aged >14 years (52% response rate), we expect the final seroprevalence of SARS-CoV-2 antibodies to be in the range of 80 to 90%. Thus, around 10 to 20% of the German population may still be susceptible to a severe disease progression because they are neither infected nor vaccinated. Final results, weighted for non-response and adjusted for test sensitivity and specificity, will be presented.

Conclusions

The RKI-SOEP-2 study will be pivotal in both, contributing to an improved understanding of SARS-CoV-2 propagation in different regional and sub-group settings and in identifying vulnerable target groups that need to be protected against future infections.

Key messages

• Dried blood self-sampling in a nationwide sample is a robust tool to estimate seroprevalence at a population level.

• As of February 2022, presumably 80 to 90% of the German population has previously been infected and/or vaccinated against SARS-CoV-2.
