Overview 

The WMS-IV provides the most advanced measure of memory and results when addressing the changing clinical landscape:

Changing Demographics

WMS-IV includes updated normative data for ages 16–90 and enhanced utility for older adults.

Emerging Clinical Needs

WMS-IV features new clinical studies and newly developed subtests and items.

Increasing Caseloads

WMS-IV reduces administration time to obtain composite scores and improves scoring rules.

Introducing: WMS-IV Flexible Approach

The WMS-IV Flexible Approach uses core and supplemental memory measures to expand the usability and utility of the WMS-IV. It is intended to assist the examiner who wants to tailor the assessment of memory by using a shorter battery or substituting alternate memory measures for primary WMS-IV subtests.

 

A closer look

The benefits

New subtests

Included batteries

Expanded clinical utility

WMS-IV includes improved floors across subtests, a general cognitive screening tool, and enhanced assessment of visual memory. It was also co-normed with the Wechsler Adult Intelligence Scale®-IV.

Enhanced user friendliness

WMS-IV features a brief older adult battery, reduced subtest administration time, minimized visual motor demands, and modified story content and administration process.

Improved psychometric properties

Updated norms, improved floors, improved subtest and composite reliability, and reduced item bias ensure WMS-IV is relevant to the changing landscape.

Spatial addition

Based on “N-back” paradigm, Spatial Addition requires minimal motor function as the client must: (1) Remember location of dots on two separate pages, (2) Add or subtract locations, and (3) Hold and manipulate visual spatial information.

Symbol span

A visual analog to Digit Span, clients are asked to remember the design and the left-to-right sequence of the design. The clients are then asked to select the correct design from foils and choose them in the correct sequence.

Design memory

Design Memory evaluates immediate and delayed recall as well as delayed recognition. It does not include drawing and reduces the opportunity to guess the correct response. Scores are obtained for spatial, details, and correct content in the correct location. Contrast scores can also be obtained.

Cognitive screener

This new screener can be used to quickly evaluate significant cognitive impairment. Use it to assess: temporal orientation, mental control, clock drawing, memory, inhibitory control, and verbal productivity.

Standard battery

This consists of the seven primary subtests that comprise the full WMS-IV battery and provide coverage for all the memory indexes. See included subtests and indexes.

OAA battery

The OAA battery was developed in the standard WMS-IV as a shorter battery for use with older adults ages 65 to 90. This battery configuration was made available for examinees ages 16 through 69 in the WMS-IV Flex. The OAA battery uses LM, VR, and Verbal Paired Associates (VPA) to derive Immediate, Delayed, Auditory, and Visual Indexes. See included subtests and indexes.

LMVR and LMDE batteries

Two shorter alternative batteries were developed: LMVR, consisting of Logical Memory (LM) and Visual Reproduction (VR), and LMDE, consisting of Logical Memory and Designs (DE). LM and VR are the most frequently used subtests in the previous editions of the WMS and provide coverage for all the memory indexes. The second configuration of LM and DE retains the content coverage with reduced motor demands. See included subtests and indexes.

VRLO and LONA batteries

The last set of alternate batteries focuses on using supplemental subtests for assessing visual memory, which is a difficult construct to measure. During the development of the WMS-IV, two additional memory subtests were created: Logos (LO) and Names (NA). These two subtests provide optional measures of visual memory with the understanding that auditory memory functioning will also affect performance on these tests. See included subtests and indexes.

Scoring & Reporting

Scores are now derived for Older Adult Battery (65–90) and Adult Battery (16–69). ability/memory discrepancy scores, index scores, and contract scores are all available.
