The RWA Scale produced exceptionally high internal consistency among US legislators

Evidence

The mean interitem correlation across all respondents averaged .41-—higher even than that among the Canadian legislators—producing a Cronbach alpha of over .95. That means the signal-to-noise ratio in these data exceeds 19:1, giving the phrase “less than .05” a new meaning. — Bob Altemeyer, The Authoritarian Specter, 3672
