Abstract
A letter to the editor is presented regarding the recently published article by González-Fernández, Sein, and Palmer (2011). In this letter, Dr. Giselle Carnaby stipulates that although González-Fernández and colleagues' article reports on the revalidation of a common swallowing assessment tool, it does not, however, fully address issues surrounding (a) the use of retrospective data for revalidation, (b) the impact of missing data on analyses, and (c) the failure to replicate an assessment's scoring system. These issues are pertinent for the readership of the American Journal of Speech-Language Pathology (AJSLP) and for the interpretation and development of future assessment tools in this area.
