Validation of the VEINES-QOL quality of life instrument in venous leg ulcers: repeatability and validity study embedded in a randomised clinical trial

Table 8 Increase in VEINES-QOL scores for those who have healed and those who have not healed after 4 months, with responsiveness coefficient

Scale	Healed		Not healed		Healed minus not healed^a			Responsiveness^b
Scale	Mean	SD	Mean	SD	Difference	95 % CI	P	Responsiveness^b
VEINES-QOL, external	4.7	9.7	2.1	7.9	2.6	0.5–4.7	0.01	0.50
VEINES-Sym, external	4.8	9.7	2.5	9.1	2.3	0.1–4.6	0.04	0.44
VEINES-QOL, intrinsic	9.8	22.1	4.3	17.2	5.5	0.8–10.2	0.02	0.48
VEINES-Sym, intrinsic	10.6	22.7	5.4	20.8	5.2	0.0–10.5	0.05	0.42

^aBigger changes in those who have healed than in those who have not healed indicate that healing is associated with change in reported quality of life
^ba value greater than zero (maximum is 1.00) indicates that the scale responds to changes over time
