Age-Specific Changes in the Effects of Social Connectedness and Loneliness on Depressive Symptoms: Evidence From the Korean Longitudinal Study of Ageing Before and During the COVID-19 Pandemic

This study also examines whether these associations vary across three age groups (45-64, 65-74, and 75 or above).
