Wpływ pandemii COVID-19 na stan zdrowia psychicznego społeczeństwa
Influence of the COVID-19 pandemic on the mental health of society

Summary/Abstract: The COVID-19 pandemic changed the lives of people all over the world, by e.g. affecting the mental health and the functioning of many families. The main goal of the research presented in this paper is to assess the influence of the COVID-19 pandemic on the mental health of members of households. The research was performed on the basis of a data set from the COVID Impact Survey carried out by the Data Foundation think tank in 2020 (during the first wave of the COVID-19 pandemic) in the USA among adult respondents. The survey used 6,768 observations. The authors estimated a model of logistic regression and models based on data mining methods, such as decision trees, XGBoost, the k-nearest neighbours method, artificial neural networks and a support vector machine. Cluster analysis allowed the division of the respondents into groups showing their characteristic features and problems, and the constructed model took into account their mental health issues and the relationship between those issues and the financial situation of households. The results demonstrate that isolation, remote education and work, and limited physical activity contribute to the worsening of the mental health of the population.
