Examining the concurrent validity of the Wide Range Achievement Test 4th edition and Wechsler Abbreviated Scale of Intelligence
by Sylvester, Richard Louis, M.A., STEPHEN F. AUSTIN STATE UNIVERSITY, 2008, 65 pages; 1458390

Abstract:

The current research investigated the relationship between the WRAT-4 and WASI in males over 40. 61 participants, predominantly Caucasian, ages 42 to 90 (M = 63.33, SD = 12.56), participated. It was hypothesized that there would be strong positive correlations between the WRAT-4 and WASI and depressed individuals would perform more poorly on both measures. A 2 (order of administration) x 2 (type of test) mixed ANCOVA used depression (as measured by the Beck Depression Inventory 2nd Edition) as a covariate and showed participants who completed the WASI first did not perform as well as participants who completed the WRAT-4 first. A 3 (test score) x 2 (depression level) mixed ANOVA was also utilized. Both hypotheses were confirmed.
