Insight into the long-term psychological impacts of the COVID-19 pandemic

Severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) has caused over 668 million confirmed infections and over 6 million deaths from coronavirus disease 2019 (COVID-19) worldwide (as of January 23, 2023) [1]. A pandemic of such magnitude poses considerable challenges to health care systems. It stretches hospitals to their limits in their capacity to care for patients [2] and places health care workers as well as vulnerable populations at severe risk. The SARS-CoV-2 pandemic resulted not only in acute illnesses, but also in long-term consequences. While there is an extensive increase in literature on the COVID-19 pandemic in general, the long-term consequences and their underlying mechanisms remain poorly understood. Thus, several new findings and aspects are highlighted in this issue of the European Archives of Psychiatry and Clinical Neuroscience. Li et al. present new insights into the long-term psychological consequences of COVID-19. They found that a high proportion of COVID-19 survivors still suffered from poor sleep quality, fatigue, anxiety, depression, and PTSD 1 year after infection [3]. Risk factors for these mental health outcomes included smoking, alcohol use, and low educational status. In addition, history of chronic disease was an independent risk factor for poor sleep quality, fatigue, depression, and PTSD. This study points to the long-term psychological impact of COVID-19 in survivors and highlights the urgent need for appropriate mental health services for psychological support. In another study, a group led by Benke and Pané-Farré examined the question of what long-term changes in mental health occurred in the general German population as a result of the pandemic in a longitudinal observational study. Their data from 1388 adults showed that depressive symptoms and loneliness increased over the course of the pandemic while life satisfaction decreased comparing baseline to 12-month follow-up. In addition, they found that particularly vulnerable groups, such as younger people or those with mental disorders, were more severely affected by psychopathological symptoms [4]. These outcomes point to a deterioration in mental health during the COVID-19 pandemic, underscoring the importance of implementing targeted health interventions to prevent the onset of severe mental illness, particularly among vulnerable groups. In addition to the long-term consequences of COVID-19 disease, the psychological and psychosocial consequences of lock downand isolation measures must be considered. To date, few studies have examined the long-term psychological effects of familial confinement and exposure to SARSCoV-2 infection in adolescents. This aspect was studied by Qu and colleagues. They found that psychological resilience was a protective factor in preventing depression and anxiety symptoms among adolescents at increased risk of infection. Emotional abuse and poor parent–child relationships were risk factors. Long-term institutional care had low psychological impact on adolescents, but SARS-CoV-2 infection rates were significantly associated with adolescent depression and anxiety. Reif-Leonhard et al. investigated suicidal behavior during the pandemic. Their data showed a decrease in suicide attempts during the pandemic, while completed suicides did not change. Suicide attempts were more likely in patients who lived alone. Age, gender, occupational status, and psychiatric diagnoses did not differ during the pandemic. The rate and number of intoxications as a suicide method also increased, and more people attempted suicide in their own homes. In addition, the colleagues assumed that a high number of suicide attempts remained unnoticed because they occurred in the home environment and the methods used were associated with lower lethality [6]. * Kristina Adorjan Kristina.Adorjan@med.uni-muenchen.de
