Wechsler Memory Scale-IV (WMS-IV; The Psychological Corporation, 2009)

Individually administered test battery designed to assess verbal (story, paired associates), visual-spatial (geometric shapes, designs and locations) and visual working memory. Scaled scores of immediate and delayed story memory (Logical Memory I, II) and Verbal Paired Associates form the Auditory Memory Index. Scaled scores of immediate and delayed Visual Reproduction and Designs form the Visual Memory Index.

Reliability coefficient of .94 to .97 in ages 16 - 69 and .97 in population of TBI patients for the Auditory Memory Index. Reliability coefficient of .95 to .97 in ages 16 - 69 and .99 in population of TBI patients for the Visual Memory Index. Test-retest reliability are; Auditory Memory Index (.83) and Visual Memory Index (.81)^a,c

Convergent validity of Auditory Memory Index, correlation coefficient of .63 to CVLT-II Trials 1 - 5 correct. Construct validity of Visual Memory Index, correlation coefficient of .70 to RBANS Total Scale score^a,c
