The COVID-19 pandemic has become the subject of intense discussion on social media platforms. Fake news and conspiracy theories about the SARS-CoV-2 virus, in particular its origin, spread, impact on health and prevention, have become especially popular. The social crisis triggered by the COVID-19 pandemic is associated with a growing tendency to believe in conspiracy theories, which in turn may contribute to an increase in anxiety tension and thus deteriorate the psychological health of citizens.

The aim of the study was to determine the relationships between the tendency to believe in false information about the COVID-19 pandemic and the severity of symptoms of anxiety and depression among the surveyed Polish citizens.

The study included 700 Polish people aged 24.7±6.34 years. We used questionnaires such as: COVID-19 Conspiratorial Beliefs Scale to measure the level of belief in false information regarding the COVID-19 pandemic, Generic Conspiracist Beliefs Scale to measure tendencies to believe in conspiracy theories, and Hospital Anxiety and Depression Scale.

Belief in false information about the COVID-19 pandemic may be associated with a slight increase in the severity of both anxiety symptoms (b=0.044; p=0.021) and depression (b=0.048; p=0.004). A factor known as belief in the criminal activity of government organizations may also contribute to predicting the increase in the severity of symptoms of anxiety (b=0.172; p=0.001) and depression (b=0.169; p=0.000) during the COVID-19 pandemic.

Belief in false information about the COVID-19 pandemic, as well as belief in general conspiracy theories, can contribute to the psychological deterioration of citizens during the COVID-19 pandemic.

No significant relationships.
