The COVID-19 pandemic has had unprecedented impacts on individuals and communities around the world. A matter of great concern is the impact of the pandemic on mental health. The isolation, fear and uncertainty caused by the virus has led to increased rates of anxiety, depression and other mental health issues. Concerns about the increasing prevalence of psychological disorders are already leading countries to include mental health and psychosocial support in their COVID-19 response plans, but despite this, major gaps and concerns remain. The multiple stressors triggered by the virus, in addition to the severe interruptions in public services, have left serious gaps in the care of those who need it most. In addition to the worsening and generalization of pre-existing mental health conditions, there is now also a need to accommodate newly developed issues. Our objective is therefore to investigate the main reasons that led patients from the Service of Applied Psychology at PUC-Rio to seek psychological treatment before (2019) and during the pandemic (2020 and 2021). Through a lexical analysis of the psychological demand forms, we intend to trace the possible transitions and aggravations between psychological demands of adults (article 1) and families (article 2) using the IRaMuTeQ software and the Reinert method, which qualitatively and quantitatively analyzes the transcribed reports. Through this analysis resource, it is possible to start mapping and investigating the subjective complaints of these patients, their development and their correlations.
