The Psychological Impact of Social Isolation During COVID-19: A Longitudinal Study

Abstract

The COVID-19 pandemic led to unprecedented levels of social isolation, with significant psychological consequences for individuals across the globe. This longitudinal study explores the mental health impact of social isolation during the pandemic, focusing on anxiety, depression, and loneliness. We surveyed 1,000 individuals in Mexico over 18 months, using standardized psychological assessments to measure changes in mental health over time. The findings reveal that prolonged social isolation led to a sharp increase in anxiety and depressive symptoms, particularly among individuals living alone. However, individuals with strong virtual social networks experienced fewer negative effects. The paper discusses the importance of digital platforms for maintaining social connections during crises and recommends public health strategies to mitigate the mental health impact of future pandemics or similar events.
