The Vanderbilt Fatigue Scale-Adult (VFS-A) is designed to assess listening-related fatigue in adults 18 years and older. There are two versions of the scales: 1) a 40-item scale typically used for research purposes and 2) a 10-item scale appropriate for clinical or research use. The scales are freely available for clinical and research use and can be downloaded below. For more information about administration and scoring of both the VFS-A-40 and VFS-A-10, please download and review the Adult Quick User Guide. For information about clinical interpretation of VFS-A-10 scores, please review the VFS-A-10 clinical interpretation guidelines.
