The rapid spread of the COVID-19 virus challenges the entire world tremendously. Yet, little research has been done in Germany on the behavior of the population in such times of crisis. In the present study (N = 320), several effects on experience and behavior within the COVID-19 pandemic were investigated in an online study: frustration of needs, social isolation, feelings of anxiety and stress, adherence to conspiracy mentality, increased alcohol consumption, and Dark Triad characteristics. In addition, self-constructed scales were used to examine one's own change in criminality tendency (SEKT-S) since the beginning of the crisis, as well as the approval of criminality tendencies in other persons (SEKT-A). Both scales were found to be highly reliable. Although a suitable fit could be found in the measurement models, a factorial structure could not be identified. High scores on the factors frustration of needs, adherence to conspiracy mentality, alcohol consumption and the dark triad turned out to be suitable predictors of criminality tendency. The Dark Triad factor represented a moderator in the relationship between need frustration and self-related crime tendency. Due to the heterogeneity of the sample studied, the results can be generalized well. We discuss the limitations of our own study and possible further research on crime in times of crisis.
