Comparison of SCAN Results with Other Auditory and Language Measures in a Clinical Population

Abstract

This study was conducted to compare results of SCAN: A Screening Test for Auditory Processing Disorders with other central auditory and language tests. The SCAN, Staggered Spondee Word test (SSW), Competing Sentence test, Peabody Picture Vocabulary Test (PPVT), and the Clinical Evaluation of Language Fundamentals-Revised (CELF-R) were administered to 155 children between the ages of 6 and 15 years. All subjects were referred for possible auditory or language processing disorders. Results showed significant correlations between the SCAN, SSW, and Competing Sentence test results except for Filtered Word and Auditory Figure Ground subtests of SCAN that were not significantly correlated with the Competing Sentence Test. Significant correlations also existed between SCAN and the PPVT, but there were no significant correlations between SCAN and the CELF-R subtests. Patterns of responses according to histories of Attention Deficit Disorders were also found.
