A longitudinal model for psychological distress in the COVID-19 crisis among brazilian graduate students

As most evidence for mental health impacts of the COVID-19 crisis is cross-sectional, the present study aimed to analyze the longitudinal development of psychological suffering among 619 Brazilian adults by assessing mental health outcomes and individual factors in two periods: a year before and a month after the break of the pandemic. As major findings, pandemic psychological suffering was directly explained by previous-year suffering, conscientiousness, and pandemic perceived stress, and correlated with pandemic suicidal ideation. Pandemic perceived stress correlated with pandemic psychological distress, and was explained by previous-year suffering, neuroticism, and conscientiousness, as well as by pandemic life satisfaction and perceived pandemic impact. Finally, pandemic suicidal ideation variance was explained by prior ideation and pandemic life satisfaction. These findings are in line with current models of mental health and highlight the importance of integrating both more stable individual factors and more transient variables towards and explanation for mental health outcomes.
