Development and standardization of SCAN-A: test of auditory processing disorders in adolescents and adults.
This paper reports on the development and standardization of SCAN-A: Test of Auditory Processing Disorders in Adolescents and Adults. The standardization version of SCAN-A included six subtests; two filtered words (FW) subtests, two auditory figure-ground (AFG) subtests, a competing words (CW) subtest, and a competing sentences (CS) subtest. Studies included development of normative results on subjects at different ages, determination of subtests to retain in the final version, investigation of test-retest reliability, and a concurrent validity study comparing the results of SCAN-A to SCAN scores obtained on the same subjects. The final version of SCAN-A contains four subtests that take 20 minutes to administer. Raw scores can be converted to standard scores and percentile ranks. Cut-off scores are suggested for normal, questionable, and abnormal performance.
