title: Standardization of European Medical Risk Related History questionnaire for use with Persian-speaking population.
abstract: BACKGROUND
  Today, the dental practitioners are finding many more medically compromised patients in their practice.
  
  
  OBJECTIVE
  The aim of this study was standardization of the European Medical Risk Related History (EMRRH) questionnaire for use among Persian population.
  
  
  METHODS
  The English original version of the EMRRH questionnaire was translated into Persian language by a forward-backward translation method. Then reliability was tested on 50 subjects. Also, the sensitivity, specificity, and validity of the questionnaire were assessed.
  
  
  METHODS
  Cohen's kappa, a measure of agreement between observers that includes an adjustment for chance agreement, was likewise calculated.
  
  
  RESULTS
  The reliability coefficient (Cronbach's alpha) of the EMRRH was above the recommended 0.7 threshold and considered excellent (alpha 0.87). Specificity of the questions was 94% and of per EMRRH item was 93%. Sensitivity per question was 86.1% and of per EMRRH item was 94%. Cohen's kappa for the questionnaire was 0.89 and for subsequent questions was 0.82.
  
  
  CONCLUSIONS
  The EMRRH (Persian version) has been shown to be valid in comparison with the gold standard (a medical history taken by a physician experienced) and this instrument would be an effectual method of history taking for the dentist.
