Popis: The aim of this study was to evaluate the psychometric properties of patient-reported visual analogue scale (VAS) ratings. All of the participants (100 Polish-speaking adults) completed a Tinnitus Functional Index (TFI) once and a 4-component VAS twice over a period of 3 days. Spearman’s correlation coefficients between the VAS score and global TFI ranged from ρ = 0.52 for VAS-coping (VAS-C) to ρ = 0.81 for VAS-annoyance (VAS-A). Using the Bland-Altman method, the agreement ranged from 93% for VAS-A to 96% for VAS-distress (VAS-D). Interclass correlation coefficients ranged from 0.67 for VAS-C to 0.90 for VAS-A. The VAS cutoff points representing significant tinnitus severity ranged from 45 points for VAS-C to 66 points for VAS-D. VAS scales are a valid and reliable brief screening tool for obtaining quick information about tinnitus.
