Background: Today, the dental practitioners are finding many more medically compromised
patients in their practice. Aims: The aim of this study was standardization of the European
Medical Risk Related History (EMRRH) questionnaire for use among Persian population.
Materials and 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.
Statistical Analysis Used: 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.
