**2. Method**

#### **2.1 Literature review**

We have performed an integrative literature review in three electronic databases: Medline, PsycINFO, and Published International Literature on Traumatic Stress (PILOTS). The electronic searches used variants of the following research terms with a syntax adjusted to each database: #1 "COVID-19" OR "Coronavirus Infections" (Medical Subject Headings – [MeSH term] AND #2 ("Health Personnel" OR "Health Care Provider" [MeSH] term); and "Mental Health" [keyword].

### **2.2 Data collection**

Manuscripts were selected primarily through the analysis of their titles and abstracts. Two researchers collected data individually in order to ensure trustworthiness of the findings, and divergences were solved by a third senior researcher. Each sample article was thoroughly read, and the information was inserted in a spreadsheet (**Table 1**) that included the author, publishing year, journal, and main findings.

## **2.3 Eligibility criteria**

Papers were analyzed based on the following eligibility criteria: at least one combination of the terms described in the search strategy in the title; written in English, Portuguese or Spanish; addressing the psychiatric impact of COVID-19 pandemic; original articles with the full text available through the Journal Portal of the Brazilian Coordination of Personal Improvement of Higher Level (CAPES), which is a virtual library created by the Brazilian Department of Health where content is restricted to authorized users. Monographs, dissertations, and thesis were excluded.

Manuscripts repeated in more than one of the databases were counted only once. Some papers were excluded because they approached other viruses/pandemics.

#### **2.4 Ethical issue**

Considering this is an integrative literature review, Resolution 510/16 of the Brazilian National Health Council (CNS, acronym in Portuguese) ensures the dismissal of submission to an Ethics Committee on Research (Human Beings).
