Description: This code can be used to calculate VFS-C and VFS-T IRT scores and VFS-P IRT subscale scores, using the raw scores from a group of respondents who completed one of the Pediatric Vanderbilt Fatigue Scales (VFS-Peds). To download the code simply select the "Generate VFS-Peds IRT Scores" folder below and then click the "Download as zip" button to save the required files. Instructions for how to use the code are contained in the .R files for a given scale or subscale. A description of the development of the VFS-Peds is provided in: Hornsby, B. W. Y., Camarata, S., Cho, S.-J., Davis, H., McGarrigle, R., & Bess, F. H. (2022). Development and Evaluation of Pediatric Versions of the Vanderbilt Fatigue Scale for Children with Hearing Loss.
