Relating mental health, health-related quality of life and well-being in the aftermath of the COVID-19 pandemic: A cross-sectional comparison in 14 European countries in early 2023

Objectives

To understand country-level differences in the population's health and well-being in Europe in the aftermath of the COVID-19 pandemic, while also investigating the internal relationships among health and well-being outcomes.

Study design

Cross-sectional study.

Methods

We collected representative panel-based samples of 1000 adult respondents per country across 14 Western European countries in early 2023. The survey used standardised instruments to assess health and well-being, including EQ-5D-5L, GHQ-12, PHQ-9, general satisfaction, the Brief Resilience Scale and the ULS-6 (Loneliness) Scale. Summary statistics of the aggregate scores for each country were calculated and ranked. Multidimensional unfolding was used to visualize the rank relationships across countries and the indices, whereby a closer distance between a country and an index indicated a higher/better rank. Additionally, two key objective country-level indices (GDP growth rate and excess mortality rates) were integrated into the analysis.

Results

Austria was found to report better status on most of the indices, while Sweden and the UK ranked consistently worse than the other countries. The loneliness, EQ-VAS and satisfaction scores were plotted further from the mental well-being scores and EQ-5D utility scores. Countries that did well in controlling excess mortality and maintaining economic growth tended to exhibit lower performance in self-reported well-being.

Conclusion

This study presents the variability in health and well-being across 14 West-European countries. Discrepancies between countries in self-reported outcomes reveal the complex interrelationship among different aspects of well-being. The study also highlights the complexities and challenges in optimising policies to maximize the overall well-being of society.
