AB  - BACKGROUND: The Long Form and Short Form of the German (original) version of the 
      Urticaria Control Test (UCT) have shown to be valid and reliable instruments for 
      assessing patients with all types of chronic urticaria (CU). The cutoff scores 
      for identifying patients with well-controlled disease were  >/=  24 and  >/=  12 for 
      Long and Short Forms, respectively. However, the sensitivity to change and 
      minimal clinically important difference (MCID) of the UCT have never been 
      systematically evaluated. This study aimed to investigate the validity, 
      reliability, screening accuracy, sensitivity to change and MCID of the 
      linguistically validated translation of the UCT into the Thai language for 
      assessing CU in the Thai population. METHODS: A structured translation and 
      pre-testing were done to cross-culturally adapt the UCT for the Thai language. 
      All measurement properties of both forms of the Thai UCT were validated in 169 
      patients with CU. RESULTS: There were strong correlations between the Thai UCT 
      score and disease activity, health-related quality of life impairment, and 
      disease control (all correlations  >/=  0.7). Good internal consistency and 
      excellent intra-rater reliability were demonstrated. The same cutoff scores to 
      define patients with well-controlled disease should be used as those recommended 
      for the original UCT version. MCIDs equated to increase in scores of 6 and 3 for 
      the Long and Short Forms, respectively, of the Thai UCT should be used to 
      identify patients who had minimal responses. Score increments of >/= 10 and  >/=  6 
      for Long and Short Forms, respectively, should be used to define patients who had 
      marked responses. CONCLUSIONS: This study confirmed the applicability of the UCT 
      for use in Thailand, a country that has a very different language and cultural 
      setting than that of Germany and the United States. Further studies are required 
      to examine the suitability of the UCT for use in the pediatric population.
