Social Class and Well-being Trajectories during COVID-19: A 4-year Longitudinal Study Revealed a Steeper Decline among Higher-class Individuals in South Korea

Abstract

Little research has examined the role of social class in the long-term impact of the COVID-19 pandemic on mental well-being. This 4-year longitudinal study in South Korea (N = 86,872; 875,967 responses) assessed well-being before (January 2019 to January 2020) and during (January 2020 to January 2023) the COVID-19 pandemic to determine whether change in well-being during this period differed by social class. We expanded the investigation to consider transitions in social class, social distancing measures, and the mechanisms underlying well-being changes according to social class during the pandemic. In particular, we assessed the moderating effects of social class on within-person changes in well-being using conducting multilevel modeling-based analyses in four approaches. First, we found that, while higher-class individuals maintained an average well-being that was higher than that of lower-class individuals, they also experienced a steeper decline in well-being over the course of the pandemic. Relative to their pre-COVID-19 levels, they experienced a significant decrease in well-being in the first, second, and third years of COVID-19, showing no sign of recovery until the pandemic neared its end. Second, this pattern persisted without regard for critical social class transitions following the pandemic: individuals remaining in the higher class during both the pre-COVID-19 and COVID-19 periods experienced significant declines in well-being relative to baseline. Third, higher-class individuals faced larger difficulties in maintaining their well-being, particularly with respect to social distancing measures, while the well-being of lower-class individuals was less affected. Fourth, perceived changes in daily life mediated observed class difference in well-being declines, showing that higher-class individuals experienced greater changes in their daily lives due to COVID-19 than lower-class individuals did, resulting in greater declines in well-being. Taken together, these findings indicate that COVID-19 transformed components of life that are essential for the psychological health of the well-off, providing novel insights into the significant power of social class in the experiences of changes in well-being, going beyond the absolute gap that has been well-established by cross-sectional studies. This indicates the need for class-targeted interventions and policies to support well-being across all socioeconomic strata in future crises.
