Construct and Known-groups Validity of the Thai-version of the Urticaria Control Test (UCT)

Construct validity (correlations)	Urticaria Control Test
	Long Form	Short Form
Urticaria Activity Score (UAS28)	−0.67*	−0.68*
Patient’s global assessment of disease severity (PatGA-VAS)	−0.81*	−0.72*
Patient’s global assessment disease control (PatGA-LS)	0.76*	0.83*
Physician’s global assessment of disease control (PhyGA-VAS)	0.71*	0.77*
Validated Thai version of Chronic Urticaria Quality of Life Questionnaire (CU-Q2oL)	−0.89*	−0.78*

*p value = < 0.0001, r > 0.60 (strong correlation). Please note that some correlations show negative values as higher scores of the UCT (well controlled disease) indicates lower disease severity (UAS, PatGA-VAS) and negative impact on healh-related quality of life (CU-Q₂oL)
