Objective: The SCAN-A (Keith, 1994) is a test for auditory processing disorders in adolescents aged 11+ and adults developed in the USA. It was previously found that the children's version (the SCAN-C) over diagnoses auditory processing disorder in UK children. This study was conducted to assess the use of the SCAN-A with UK adults. Design: Comparison of UK adult's SCAN-A performance to US-based normative data. Study Sample: 31 UK adults aged 19 to 64 years (M 24, sd 10). Results: The UK sample scored significantly worse on three subtests: the Filtered Words (FW), Competing Words (CW) and Competing Sentences (CS) sections as well as on the Total Score. Conclusions: Applying US norms to UK adult's performance results in a high rate of over-identification of listening difficulties. Alternative UK norms are provided and implications for use of the SCAN-A with UK adolescents and adults are discussed.
