Perceived stress in different countries at the beginning of the coronavirus pandemic

Objective The coronavirus has spread around the world, causing an ongoing pandemic. After the lockdown and quarantine protocols, an evaluation of the population's current emotional state was made through a web-based survey available in both English and Spanish. The objective was to observe how respondents perceived stress and worry as a result of COVID-19. Methods The survey gathered data across three sections: socio-demographic data, the Perceived Stress Scale (PSS-10) by Cohen, and additional queries on current worries and behaviors due to this pandemic. Results The survey received 1523 respondents from 48 countries. The mean of the PSS-10 score was 17.4 (SD 6.5). Significantly higher scores were observed among women, young adults, students, and those who expressed concern about getting infected and considered themselves high-risk. No significant differences were observed between health professionals and other professions. Conclusions We describe an increase in stress levels due to the COVID-19 and point out groups at high risk. These findings could help to address the mental health care that is needed.
