General and maladaptive traits as predictors of specific conspiracy beliefs related to COVID-19 and Russian-Ukrainian war: three-wave longitudinal study

Abstract

The aim of the study was to investigate how general personality traits (Big Five) and maladaptive traits (Personality Inventory for DSM-5) predict specific conspiracy beliefs related to COVID-19 and the Russian-Ukrainian war. 925 participants from Slovakia, recruited via an online panel of a research agency (50.6% women, mean age 50.9 years), were interviewed in October 2021 with the Big Five Inventory Short (BFI-S) and the Personality Inventory for DSM-5 Brief Form (PID-5-BF). Later (July-August 2022 and April-May 2023), they completed the original scales to measure COVID-19 and Russian-Ukrainian war conspiracies. The results showed that after controlling for demographic variables, belief in specific conspiracies was positively predicted by extraversion and negatively predicted by agreeableness. Of the maladaptive traits, only psychoticism was a positive predictor of specific conspiracies. Since the effects were consistent across all types of conspiracies, the results suggest that personality traits may play a role in how people come to believe in specific conspiracies.
