Effects of the COVID-19 pandemic on psychological health in a sample of Italian adults: A three-wave longitudinal study.

The COVID-19 pandemic and the resulting societal restrictions have had negative implications for mental health in the general population. The aims of the present longitudinal study were (i) to investigate changes in psychopathological symptoms and psychological well-being in a sample of Italian individuals surveyed at different points of the pandemic and (ii) to evaluate the potential risk and protective factors associated with the psychopathological outcomes. Self-reported data on psychiatric symptoms, and psychological well-being were collected in March 2020 (T0, the lockdown phase), in May 2020 (T1, the end of the lockdown phase), and in November 2020 (T2, the second wave of COVID-19 infection). 1258 participants (M=23.43, SD=6.45; 75.4% female) were recruited at T0. Of these, 712 also completed the T1 survey, and 369 also completed the T2 survey. A significant decrease in anxiety, depressive, posttraumatic, and obsessive-compulsive symptoms and a significant increase in psychological well-being were observed from T0 to T1. All psychopathological symptoms increased, and psychological well-being decreased significantly from T1 to T2. Several demographic, psychological and COVID-19-related factors emerged as predictors over the course of the pandemic. The current findings indicated that psychological health covaried with the intensity of the COVID-19 pandemic and the associated societal restrictions.
