Green’s WMT, MSVT,
Nonverbal-MSVT & MCI for Windows
Paul Green, Ph.D.,
Clinical Neuropsychologist Fellow, National Academy of Neuropsychology
Do you wish you could look at a simple chart and
immediately
see that case 1 failed an effort
test because of genuinely severe
impairment, whereas case 2 shows
unreliable and invalid test data?
Can you easily see the difference
between poor effort versus dementia?
Now it is possible. Read
on.
Q) Which effort
tests can achieve 95% or 100% specificity in dementia?
A)
For most effort tests, the answer is a definite "No". The outcome of
such tests (e.g. B-TEST, TOMM, RDS, ASTM) is only a pass or a
fail and many people with dementia cannot pass. Lowering the cut-off
does not solve the problem. However, the WMT, MSVT &
NV-MSVT produce specific profiles in dementia, which are not the same as
those arising from poor effort.
WMT in
12 languages: English, German, Spanish, French, Dutch,
Portuguese, Danish, Hebrew, Turkish and Russian with Mandarin and Italian as
additional oral form options. In the WMT program, just choose OPTIONS, CHANGE LANGUAGE.
MSVT in
10 languages:English, German,
Dutch, Spanish, French, Portuguese,
Norwegian, Danish, Swedish and "Nonsense language".
NV-MSVT in any language:It is a nonverbal
task and there are only images on screen (no words).

which the Test of Memory Malingering (TOMM) was compared, the TOMM achieved
very high PPV (.98) and acceptable NPV (.78). How to incorporate the
strategy used into clinical practice is discussed".

In his Foreword to the manual for the Word Memory Test for Windows (Green, 2003), Dr. Paul Lees-Haley wrote "Neuropsychological assessments are no longer complete without evaluation of effort."
In doing so, he was anticipating by at least two years the position paper on Symptom Validity Testing from the National Academy of Neuropsychology (Bush, Ruff, Troster, Barth, Koffler, Pliskin, Reynolds and Silver, 2005, Archives of Clinical Neuropsychology, Volume 20, pages 419-426), which stated that it is necessary to evaluate symptom validity objectively in any neuropsychological assessment.

The
WMT,
MSVT, NV-MSVT and MCIprograms have many advanced features for
your convenience, in addition to automated test administration, scoring and
reporting of results. Each program allows you to compare your patient's
scores with data from numerous comparison groups, using flexible charts or
tables.
The WMT graph automatically
selects the four comparison groups whose profiles are most similar
to your client's. This will soon be a feature of all our tests.
Technical support for test users includes frequent program updates
and inclusion in a private internet users’ discussion group (WMT USER group)
that allows users to stay current with test administration and research, and
help interpreting WMT results via email by Dr. Green.
The program automatically do a safe back-up of all test data each
time they close. Results and demographics are easily saved as an
Excel file.
Who did the WMT, MSVT, NV-MSVT & MCI research?
Dr. Paul Green, a practicing Clinical Neuropsychologist for
over 30 years, invented the WMT, the MSVT, the nonverbal MSVT and the MCI.
Many
colleagues around the world have freely contributed to the validation of these tests.
Is the WMT Free
Recall score in a single case significantly different from the mean
score from a particular group of interest?

See the abstract of this paper in press, showing a very low
false positive rate on MSVT in dementia because of profile analysis.
Note that MSVT data do not just
yield 'pass' or 'fail' but that there is a specific "dementia profile",
which is unlike that from simulators.

Abstract
We prospectively evaluated performance of 63
referrals to a memory disorders clinic who
received the Medical Symptom Validity Test (MSVT)
as part of their standard neuropsychological
evaluation. The patients were grouped based on
independent medical diagnoses and presence or
absence of a potential financial incentive to
under-perform. Twenty-seven patients (42.9%)
scored below cutoffs on the MSVT symptom
validity indices. Two individuals in the
potential financial incentive group showed clear
signs of invalid responding (18.2%). Twenty-two
of the remaining 25 patients who failed the
symptom validity indices corresponded to the
dementia profile. Three individuals did not
correspond to the dementia profile but are
thought to have performed validly representing a
4.8% false positive rate. When considering all
MSVT indices, the base rate of invalid
responding in the potential financial incentive
to under-perform group increased to 27.3%.
Combining all groups our base rate of invalid
responding was 4.8%. Specific performances are
presented.

These findings were replicated by Robert Frerichs (Glenrose Hospital) in a
NAN poster, which will hopefully lead to publication soon.

DO YOU USE THE FBS & RBS? If
so, see Roger Gervais, P. Lees-Haley & Y. Ben Porath's poster on jointly
using FBS and RBS to get better prediction of cognitive symptom
exaggeration. For the poster click links.
In the graph, bars show percent failing SVTs.
Bar 2 is "High FBS/Low RBS" and bar 4 is "High FBS/High RBS".
Note the difference in SVT failures in these two groups. The
first group is "Low FBS/Low RBS" and the fourth group is "High FBS/High
RBS".
