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: firstname.lastname@example.org Eve Galker, Copenhagen, e-mail: email@example.com firstname.lastname@example.org Acknowledge: Maj-Britt G Lauritsen, Copenhagen for the validation of the test
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.
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.
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.
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.
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-koeff.P-value –Girl0.190.005 –Age0.49<0.0001 –Education father0.110.03 –Audiometry0.30<0.0001 –Tympanometry0.200.01 –Language (Reynell) 0.59<0.0001 –Teacher (vocabulary) 0.35<0.0001 –Parents (vocabulary) 0.150.01
Validation by PhD MajBritt G Lauritsen Galker score associated to (adjusted) Gamma-koeff.P-value –Age0.33<0.0001 –Language (Reynell) 0.35<0.0001 –Teacher (vocabulary) 0.26<0.0001
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.
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
