Reduced accuracy of classification with a short form of the Speech Sounds Perception Test.

This study attempts to cross-validate the accuracy in classification of Golden and Anderson's (1977) abbreviated version of the Halstead Speech Sounds Perception Test. A relatively high correlation was obtained between their short form and the standard long form for a sample of 150 patients, aged 15 to 70 yr. However, the long form was more accurate in discriminating between 31 brain-damaged and 31 nonbrain-damaged patients. These results suggest that the use of the short form of this test may reduce accuracy of classification.
