The aim of this research is to examine the role of financial worry as a significant element contributing to the deterioration of mental well-being amid the COVID-19 pandemic. The data utilized in this study originated from four waves of the ALP survey, which were conducted between June 2020 and March 2021. This study employed a multilevel modeling approach to analyze the longitudinal dataset. The findings indicate a positive correlation between financial worry and symptoms of depression. These findings suggest that financial worry amplifies the fluctuations in depressive symptoms over time, although this intensifying effect diminishes as time passes.
