ABSTRACT
BACKGROUND:
In clinical routine, vocal fatigue is a common symptom in patients with dysphonia.OBJECTIVE:
The aim of this study was to conduct a transcultural translation of the Vocal Fatigue Index (VFI), a standardized subjective questionnaire. Furthermore, pretesting and prevalidation were performed in 20 subjects, with comparison to the Voice Handicap Index (VHI9i) and the Vocal Tract Discomfort Scale (VTD). MATERIALS ANDMETHODS:
The translation, content review, and pretest of the German Vocal Fatigue Index (VFI-D) was divided into four sections 1. transcultural translation, 2. expert voting on comprehensibility, 3. test of comprehensibility through cognitive interviews in 15 participants, 4. pretest of the VFID with cross validation compared to VHI9i and VTD in 20 subjects. This process corresponds to current standards for transcultural translation and adaptation of questionnaires.RESULTS:
According to expert voting and cognitive testing, the VFID is correct and comprehensible (intercoder reliability κâ¯= 0.66). The factor analysis revealed three distinguishable parts VFID part 1 correlates strongly with VHI9i and VTD, VFID part 2 with VTD only (rhoâ¯≈ 0.800 each), and VFID part 3 correlates only weakly with VHI9i and VTD (rhoâ¯≈ 0.585). Thus, convergence and divergence validity are proven.CONCLUSION:
The first German version of the VFID might be a base for further research on symptoms, causes, and treatment options in vocal fatigue. Particularly patients in voice-intensive professions may benefit.Palavras-chave
