**Abstract**

The lack of specific treatment and knowledge about the exact pathophysiology of the 2019 Coronavirus disease (COVID-19) and its vaccines makes the organic aspects of the pandemic a concern and puts the psychiatric consequences and psychological effects of SARS-CoV-2, COVID-19, in second place. Hence, the psychiatric impacts of the COVID-19 pandemic have not been well established yet. We have performed an integrative literature review in three electronic databases: Medline, PsycINFO, and Published International Literature on Traumatic Stress (PILOTS). The findings were then divided into five subcategories: impacts of COVID-19 on the mental health of psychiatric patients; use of technology as an ally in combating impacts on mental health in the context of the COVID-19 pandemic; mental health promotion measures in the context of the COVID-19 pandemic for the population; mental health promotion measures in the context of the COVID-19 pandemic for health professionals; and mental health in specific groups in the context of the COVID-19 pandemic. This study has showed that the situation and measures proposed to fight the COVID-19 pandemic cause stress, anxiety, fear, and uncertainty in the population. Psychiatric patients, the elderly, refugees, and migrant workers are more vulnerable due to the stigmatization and lack of specialized support in health services and reduced access to medications. Therefore, they require care from governments and health authorities. In addition, measures to promote hospital health for health professionals seem to be essential to improve care and reduce the psychologic/psychiatric impacts on professionals. Thus, technology is a valuable ally in this process.

## **1. Introduction**

A pandemic creates its own objective reality as a backdrop for all forms of psychopathology. There are economic downturns, job layoffs, prolonged school and business closings, and threatened supply chain disruptions during such period [1–5]. It also compromises the care and mental health of individuals who already have diseases.

According to the WHO [6], 792 million (10.7%) people in the global population have a mental disorder – 264 million (3.4%) with depression, 284 million (3.8%) with anxiety disorders, and 46 million (0.6%) with bipolar disorders. However, the lack of a specific treatment, knowledge about the exact pathophysiology of the disease and its vaccines makes the organic aspects of the pandemic a concern and puts the psychiatric consequences and psychological effects of COVID-19 in second place [7–9]. Thus, the psychiatry impacts by COVID-19 pandemic have not been well established yet.

We aimed to carry out an integrative literature review based on the following guiding question: What practical contributions does the current scientific literature may provide regarding the impact of COVID-19 on mental health? This review highlighted that not only previous mental illnesses are exacerbated during a pandemic, but also negative feelings. In addition, pandemic prevention and control measures can be triggers for causing the population's sickness.
