Abstract
The objectives of this study were to describe severity of psychological distress (event-related stress, anxiety, and depression) during the second stage of COVID-19 pandemic in Mexico, and to explore associations between the indicators of psychological distress, sociodemographic characteristics and specific concerns about COVID-19. This report serves as a baseline measure of a longitudinal project to evaluate progression of psychological distress across stages of the COVID-19 pandemic in Mexico. An online survey was conducted in the State of Mexico from April 8th -18th, 2020, in a sample of men and women who are beneficiaries of a welfare institution in the region. Variables were measured with the Impact of Event Scale-6, Patient Health Questionnaire-9, General Anxiety Disoder-7, and a questionnaire of concerns about COVID-19. A total of 5974 participants were analyzed. Moderate levels of psychological distress (with 23.6% of participants meeting significant event-related stress, but mild levels of depression and anxiety) were found, as well as high values in all concerns about COVID-19, especially regarding financial disruption, worsening of local security and concern of a family member becoming infected. These concerns associated mild-to-moderately with the indicators of psychological distress. Higher values of event-related distress were found in women, individuals with higher educational attainment and those with any current high-risk medical diagnosis, though the effect sizes were mild. Though psychological distress and concerns about COVID-19 have reached significant levels during the pandemic in Mexico, overall, they have not yet reached dysfunctional levels.
