"The validation of the Barron Ego-Strength Scale and the Welsh Anxiety Index was checked by comparing a sample of 50 Australian students with a matched sample of 50 patients in a psychiatric clinic." Among the findings it was seen that "the validity of the Es scale is confirmed in that it successfully distinguishes the normal from the clinical subjects. Its validity thus generalizes beyond the American culture" and "the validity of the AI is confirmed in that it successfully distinguishes the normal from the clinical sample. Its validity thus generalizes beyond the American culture." (PsycINFO Database Record (c) 2006 APA, all rights reserved)
