Voice Disorder Index
The Voice Disorder Index (VDI) or Stimmstörungsindex
(SSI) has been established
in Europe as a reliable tool for describing voice-dependent
quality of life. The sole purpose of the VDI is to provide some
preliminary information regarding the severity of voice problem as it
relates to the most common activities in daily life.
Nawka developed a score
by using 12 questions, called in German Stimmstörungsindex [SSI] or
English Voice Disorder Index [VDI]).
Comparability and Conversion of
Stimmstörungsindex (SSI) and Voice Handicap Index (VHI)
The Voice Handicap Index
(VHI) has been established internationally as a reliable tool for
describing voice-dependent quality of life. Nawka developed a new score
by using 12 questions out of the VHI, called SSI (Stimmstörungsindex).
The SSI has proven its role in daily clinical routine, main problem
remains a lack of comparability of the SSI (range: 0 - 48) to the
internationally established VHI (Voice Handicap Index) (range: 0 - 120).
Aim of our study was to demonstrate that by a simple multiplication of
SSI scores a statistically significant correlation with scores of the
VHI can be achieved. Methods: 210 consecutive
patients of the ENT University Hospital Graz were evaluated by the
German version of VHI. We calculated total score of VHI as well as the
score of the SSI. By multiplication of the SSI scores by 2.5 we
calculated a new score, called „VHI-korr”. This score was compared with
the VHI. Results: We can demonstrate that by
simple multiplication of the SSI scores by 2.5 a statistically
significant correlation to the VHI can be achieved (r = 0.98; p < 0.01).
Conclusion:
The SSI- based „VHI-korr” provides good international
comparability of voice disorders with VHI and allows to maintain the
common use of SSI in daily clinical routine.

lingWAVES Voice Disorder Index module
lingWAVES offers a free usable VDI module with 12-item.
The module includes a print out function for a patient related form,
an editor to transfer the patient data to a patient related database and
a classification view of the results.
Input form to transfer the patients data
from the print out form to the database.
Classification view of 4 VDI results for one
patient: The view shows the VDI scores over the time above and the F
(functional), P (physical) and E (emotional) components at the
bottom.
How to use it
Using the VDI module is very easy:
-
Open lingWAVES.
-
Open the client/patient manager (click
icon
 )
and select the patient from the list above or create a new one (icon
 ).
At a minimum for a new patient you have to fill in surname and first
name.
-
Open a new VDI session (click on the
icon
at the bottom). You will see a new VDI window.
-
Print out a form for the patient (click
on the icon
in the menu bar). Forward the printed form to the patient and ask
the patient to fill in the form.
-
Transfer the patients data to the VDI
module.
-
After transfer click on the
"Classification" tab to see the VDI result. The classification view
will show the recent VDI result (marked geen) and all other VDI
results of former VDI sessions (marked red).
-
Print out the VDI results. Click on the
printer icon
in the menu bar. Note that you can define print out options. Select
in the printer dialog tree Modules > VDI and click on the button
"Details ...". Here you can also set up standard printing options.
