Unfounded beliefs, distress and powerlessness: A three-wave longitudinal study.

The aim of the study was to examine the relationships between unfounded COVID-19 beliefs and distress and powerlessness, specifically, whether distress and powerlessness are causes or consequences of unfounded COVID-19 beliefs represented by conspiracy beliefs and pseudoscientific beliefs regarding treatment and measures. Unfounded beliefs were assessed using the COVID-19 Unfounded Beliefs Scale; distress was measured with the Symptom Checklist-10, and powerlessness was measured with four items measuring the feeling of losing control. Data collection took place during three phases of the pandemic in Slovakia (October 2021, N = 1838; July 2022, N = 1,420; April 2023, N = 925). Results suggest that individuals with stronger unfounded beliefs about COVID-19 reported greater powerlessness longitudinally, and individuals with stronger COVID-19 unfounded beliefs treatment and measures reported greater distress longitudinally (notably, beliefs about COVID-19 measures in the first wave were associated with distress in the second wave, and beliefs about COVID-19 treatment in the second wave were associated with distress in the third wave). The present findings corroborate an existential threat model of conspiracy theories that says the relationship between unfounded beliefs and indicators of well-being is bidirectional, so interventions should be focused both on eliminating the unfounded beliefs and strengthening well-being.
