RWA scores shift substantially in individuals across adulthood (r=.59 over 18 years)

Evidence

Results. The intercorrelation of responses to the twenty-eight RWA Scale items averaged .22, yielding an alpha of . on this go around—a little higher than that obtained in 1976. But individual scores proved much less stable, the “‘eighteen-year test-retest reliability” being .59. (The 1986 “twelve-year test-retest reliability” had been .62.) Many people had changed a great deal. — Bob Altemeyer, The Authoritarian Specter, 1127
