Shortening the Speech Sounds Perception Test.

Abstract

Statistical means of shortening the Speech Sounds Perception Test were examined. Stepwise multiple regression analyses indicated that a 30-item version correlated quite highly with the 60-item version. Group means for representative clinical groups were presented, but no strong differences emerged using either version. Inclusion of length of stay and number of previous admissions as covariates did little to enhance the predictive validity of either form. Finally, the correlation of the 30-item test with demographic variables showed that age correlated most, followed by occupational status. these results were interpreted as indicating that the 30-item version could be used while maintaining the clinical utility of this test.
