VSS-G = VSS-G total score, VSS-VER = VSS vertigo subscale, VSS-AA = VSS somatic anxiety subscale; UCLA-DQ1 = self-estimated frequency of dizziness, UCLA-DQ2 = self-estimated intensity of dizziness, UCLA-DQ3 = self-estimated impact of dizziness on daily activities; disability = self-rated mild, moderate, severe disability.
