Title: The GALKER test; a speech reception in noise test for 3 to 6 year-old children.


1
The GALKER test a speech reception in noise test
for 3 to 6 year-old children.
  • Jørgen Lous, Research Unit of General Practice,
  • Institute of Public Health, University of
    Southern Denmark, e-mail jlous_at_health.sdu.dk
  • Eve Galker, Copenhagen, e-mail ejgalker_at_mail.dk
  • Acknowledge Maj-Britt G Lauritsen, Copenhagen
    for the validation of the test

2
Background
  • We have developed a speech reception in noise
    test to identity children with problems hearing
    and understanding verbal communication due to
    middle ear problems.

3
Method
  • The test has 35 test words presented by a speaker
    under heavy background noise as in day care
    centre to day
  • The child has to point at one of two alternative
    pictures on the screen.
  • The child uses
  • hearing,
  • lip-reading,
  • knowledge about the used words,
  • interpretation of the drawings illustrating the
    spoken word.

4
Method
  • The Galker test has been evaluated on 370
    children in a PhD study by Maj-Britt Glen
    Lauritsen in Hillerød. Now the test is used by
    several speech and language therapists.
  • The test is available on DVD and takes 5½
    minutes.

5
Results
  • The Galker score is now standardized to children
    between three and six years. We have chosen a cut
    point between 80 and 20.The lower quintile is
    failures
  • The children find the test interesting and only a
    few in the youngest group have problems
    completing the test.

6
Results
  • We have found god correlation between
    tympanometry, Galker score, the language test of
    Reynell, and the observation of functional
    hearing in the day care centre.

Validation by PhD MajBritt G Lauritsen
  • Galker score associated to (unadjusted) Gamma-k
    oeff. P-value
  • Girl 0.19 0.005
  • Age 0.49 lt0.0001
  • Education father 0.11 0.03
  • Audiometry 0.30 lt0.0001
  • Tympanometry 0.20 0.01
  • Language (Reynell) 0.59 lt0.0001
  • Teacher (vocabulary) 0.35 lt0.0001
  • Parents (vocabulary) 0.15 0.01

Validation by PhD MajBritt G Lauritsen
  • Galker score associated to (adjusted) Gamma-ko
    eff. P-value
  • Age 0.33 lt0.0001
  • Language (Reynell) 0.35 lt0.0001
  • Teacher (vocabulary) 0.26 lt0.0001

Conclusion
  • The results indicate that the Galker-35 provides
    valid and reliable measurement of speech
    reception in noise.
  • The method may potentially be useful to detect
    children who are disabled in daily communication
    by OME.
  • Further research will focus on the associations
    between the Galker-35 and measures of language
    development, hearing, and Quality of Life.

10
Perspective
  • At the moment the test is pilot-tested at the
    four-year examination in the University Practice
    in Odense.
  • We hope this testing will show that the test can
    be used in general practice to identify children
    with problems understanding the spoken word.
  • And maybe on the web for parental use with their
    kids
