Reliability and Test Environment of the SCAN-A with Children Ages 12-15

The SCAN-A is an extensively applied auditory processing screening tool to be used with adolescents and adults 12-to-50 years of age. The SCAN-A includes 4 subtests: Filtered Words, Auditory Figure-Ground, Competing Words, and Competing Sentences, and requires about twenty or so minutes to administer. Different versions of this screening tool exist (e.g., SCAN and SCAN-C) which are standardised for use with children under Twelve years of age. However, past reports suggest that test-retest reliability is bad and test environment impacts performance by young children. Within this research, the effect of test environment (sound attenuating booth versus quiet room) and test-retest reliability for the 12-to-15 year old age group was explored. Thirty individuals, ages 12-to-15 years old, who were typically developing, were tested using the SCAN-A four times, two times both in a quiet room and a sound attenuating booth, with testing in both environments conducted one month apart…
