Psychological distress in Spanish-speaking countries during the COVID-19 pandemic: A systematic review and...

Psychological distress (PD) has increased significantly during the coronavirus disease 2019 (COVID-19) pandemic. In Spanish-speaking countries, with their cultural, social, and economic diversity, this phenomenon has become particularly relevant and has been aggravated by factors such as socioeconomic inequalities and unequal access to mental health services. The aim of this systematic review was to consolidate the available knowledge on PD in Spanish-speaking population groups by assessing both the prevalence of symptoms and the associated factors in different demographic groups and geographic contexts, during the COVID-19 pandemic.

A systematic review following the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) statement was conducted in the Web of Science, PubMed, and Scopus electronic databases in January 2025. The search included studies published from the beginning of the pandemic until May 2023. The Joanna Briggs Institute's critical assessment tool was used to evaluate the chosen studies' methodological quality.

A total of 53 studies were included in the review, which involved research conducted in Spain, Peru, Chile, Ecuador, Argentina, and Colombia. The results revealed a high prevalence of PD in these countries, especially among healthcare workers, women, and young people. The assessment methods used included the General Health Questionnaire (GHQ, GHQ-12, and GHQ-28 versions), the Kessler scale (K-6 and K-10 versions), and the 90-symptom checklist questionnaire (SCL-90-R), that allowed obtaining various dimensions of PD. The studies also highlighted the importance of the sense of coherence and work engagement as protective factors.

In the COVID-19 pandemic, PD was analyzed to be severe in Spanish-speaking countries, pointing to the need for specific and culturally adapted interventions to address this public mental health crisis. This is why public health policies must focus on the prevention and treatment of PD, with special attention to the most vulnerable groups.
