Thus, the aim of this study is to evaluate the impacts of the pandemic on the prevalence of anxiety and depression. Considering this, it was used data from the European COvid Survey (ECOS) and Our World in data, including information for 9 different waves and 7 European countries. To estimate the consequences of a set of pandemic-related factors (such as the dominant variant, Oxford stringency index, number of new cases, etc.), Linear Probability Models with Fixed Effects were used, and then different approaches were applied to test the robustness of the results. The main conclusion was that, in fact, the pandemic impacted negatively on mental health but was not the main cause behind the presence of extreme cases of anxiety or depression.engHealth economicsMental healthCOVID-19DepressionAnxietyEuropemaster thesis203312481
