title: Validation of the Thai version of a screening questionnaire for detection of systemic lupus erythematosus.
abstract: OBJECTIVE
  The present study was performed to assess the sensitivity and specificity of the translation questionnaire for Systemic Lupus Erythematosus (SLE) in Thai speaking populations.
  
  
  METHODS
  The 10- item questionnaire was applied to out-patients at the rheumatology clinic of the Chiang Mai University Hospital. One hundred and thirty-nine SLE, 109 Rheumatoid Arthritis (RA), and 35 Scleroderma (Scl) patients, as well as 88 Healthy Controls (HC) were enrolled into the present study.
  
  
  RESULTS
  All subjects completed the questionnaire within 2 minutes. A positive response to three or more questions of the questionnaire gave a sensitivity and specificity of 92.81% and 76. 39%, respectively, and was comparable to the original version.
  
  
  CONCLUSIONS
  This Thai-version of the screening questionnaire should be applied in the general population to determine the prevalence of SLE.
