Table 5 Kendall’s Tau rank correlation coefficients of VSS with self-estimated disability and 3 items of UCLA-DQ

Kendall-Tau n = 202	VSS-G	VSS-VER	VSS-AA	frequency	intensity	disability
VSS-VER	.711^**
VSS-AA	.703^**	.397^**
frequency (UCLA-DQ1)	.317^**	.262^**	.299^**
intensity (UCLA-DQ2)	.227^**	.275^**	.108^*	.101
disability	.400^**	.385^**	.321^**	.369^**	.469^**
impact on daily activities (UCLA-DQ3)	.281^**	.309^**	.172^**	.133^*	.590^**	.508^**

** correlation is significant on a 0,01 Level (two sided).
* correlation is significant on a 0,05 Level (two sided).
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.
