Major journals have sounded the call for social psychologists to do research on the novel Coronavirus (COVID-19). Such research is only as good as the measurements used. Across three studies (total n = 984), we developed a battery of social psychology-relevant questionnaires to measure COVID-19 phenomena: (1) Perceived Coronavirus Threat Questionnaire, (2) Governmental Response to Coronavirus Questionnaire, (3) Coronavirus Impacts Questionnaire, and (4) Coronavirus Experience Questionnaire. Exploratory (Study 1) and Confirmatory (Studies 2 and 3) Factor Analyses revealed excellent factor structures for the one-factor Perceived Coronavirus Threat, the six-factor Governmental Response Questionnaires, and the three-factor Coronavirus Impacts Questionnaire. The three-factor Coronavirus Experience Questionnaire yielded poorer psychometric properties overall. Given that brevity is often desired for online studies, we further recommend psychometrically sound short versions of each questionnaire. Taken in total, this work offers social psychology researchers a battery of questionnaires to measure Coronavirus-related phenomena for the duration of the pandemic in U.S. participants.

Is left-wing authoritarianism (LWA) closer to a myth or a reality? Twelve studies test the empirical existence and theoretical relevance of LWA. Study 1 reveals that both conservative and liberal Americans identify a large number of left-wing authoritarians in their lives. In Study 2, participants explicitly rate items from a recently-developed LWA measure as valid measurements of authoritarianism. Studies 3-11 show that persons who score high on this same LWA scale possess the traits associated with models of authoritarianism (while controlling for political ideology): LWA is positively related to threat sensitivity across multiple areas, including general ecological threats (Study 3), COVID disease threat (Study 4), Belief in a Dangerous World (Study 5), and Trump threat (Study 6). Further, controlling for ideology, high-LWA persons show more support for restrictive political correctness norms (Study 7), rate African-Americans and Jews more negatively (Studies 8-9), and show more domain-specific dogmatism and attitude strength (Study 10). Study 11 reveals that the majority of the effects from Studies 3-10 hold when looking only within liberals, thus revealing these effects are about liberal authoritarianism. Study 12 uses the World Values Survey to provide evidence of Left-Wing Authoritarianism around the globe. Taken in total, this large array of triangulating evidence from 12 studies comprised of over 8,000 participants from the U.S. and over 66,000 participants world-wide strongly suggests that left-wing authoritarianism is much closer to a reality than a myth.
