Central Auditory Processing Disorder is a complex issue that affects many school-age children who require these processing skills to succeed in school. Prevalence has been found as high as 7% in this population making it a growing issue that must be addressed. Evaluating this population is exceedingly difficult due to the challenging nature of the pediatric population which requires a testing measure that will accomplish this task accurately and efficiently. The purpose of this paper is to systematically analyze the existing literature on the SCAN-C in order to investigate its’ reliability and validity in diagnosing Central Auditory Processing Disorders. This paper included studies completed after 1985 with a minimum of 10 participants.
Participants were required to fall within the ages of 5 and 13 and were previously tested for normal hearing or any other learning disabilities that would negatively affect the test results. Results revealed the increased performance after children were re-tested following a 6-7 week time period. In addition, results found that other tests such as the MAPA and the CELF-R contained aspects of APD that were not found in the SCAN. These results bring into question the validity of the SCAN and SCAN-C as a standalone diagnostic tool for APD in school age children.
