Rasch modified NEI VF-11R or actually the VF-11R?

摘要

We would like to point out a few errors in the recent article by Kinard et al. According to Figure 1, the questions that were used constitute the Visual Function Questionnaire VF-11R (VF-11R), which is one of two revised versions of the Visual Function Index 14 questionnaire put forward by Gothwal et al. (R stands for Rasch, given that Rasch analysis was used to justify the revisions and provide interval scoring.) However, in the article, the VF-11R is wrongly referred to as "National Eye Institute Visual Function Questionnaire 11R (NEI VF-11R)," and it is cited incorrectly (refer to reference 4, Pesudovs et al. 2010 in Kinard et al.'s paper). The article by Pesudovs et al. does offer several Rasch-modified versions of the NEI VFQ, but none of the modified versions are the NEI VF-11R. The correct reference should be the Gothwal et al. paper published in JCRS in 2010.
