Kinesthetic aftereffect scores are reliable.

Résumé

The validity of the kinesthetic aftereffect (KAE) as a measure of personality has been criticized because of KAE's poor test-retest reliability. Systematic bias effects render KAE retest sessions invalid and make test-retest reliability an inappropriate measure of KAE's true reliability. Internal consistency calculations, a better estimate of KAE's true reliability, have been flawed in the past. New analyses of internal consistency data from 10 samples using 2 different KAE procedures are presented. Internal consistency of KAE scores was found to be high (median .89 for 5 samples with A. Petrie's [1967] procedure and median .59 for 5 samples with the procedure of D. Weintraub et al [see PA, Vol 53:2221]). Some increment in reliability can apparently be obtained by extending the number of trials in the Weintraub procedure.
