Applicability of Central Auditory Processing Disorder Models

from the American Journal of Audiology

Purpose: Central auditory processing disorder ([C]APD) is a relatively recent construct that has given rise to 2 theoretical models: the Buffalo Model and the Bellis/Ferre Model. These models describe 4 and 5 (C)APD categories, respectively. The present study examines the applicability of these models to clinical practice. Neither of these models was based on data from peer-reviewed sources.

Method: This is a retrospective study that reviewed 178 records of children diagnosed with (C)APD, of which 48 were retained for analysis.

Results: More than 80% of the children could be classified into one of the Buffalo Model categories, while more than 90% remained unclassified under the Bellis/Ferre Model. This discrepancy can be explained by the fact that the classification of the Buffalo Model is based primarily on a single central auditory test (Staggered Spondaic Word), whereas the Bellis/Ferre Model classification uses a combination of auditory test results.

Conclusion: The 2 models provide a conceptual framework for (C)APD, but they must be further refined to be fully applicable in clinical settings.
