VALIDATION OF THE PERSIAN VERSION OF THE BRIEF PAIN INVENTORY

Abstract

Any pain relief program must include adequate measurement and assessment of pain. The brief pain inventory is a comprehensive instrument for pain assessment in different countries. The Persian version of the brief pain inventory (BPI-P) is the first pain related questionnaire that is validated in Iran. Aim of this study was to validate BPI-P. From October 200I to September 2002 a total of 118 pain outpatients completed the BPI-P. Similar to the original version of the BPI, factor analysis for the Persian version showed a common factor for pain intensity and a second factor for pain-related interference with a function comparative fit index of 0.86 confirming this model. Comparing the validity and reliability of the BPI-P with the original one confirmed that the BPI-P had the appropriate psychometric data. Acta Medica lranica, 43(6): 425-428; 2005
