title: Translation and psychometric evaluation of Persian versions of Burn Specific Pain Anxiety Scale and Impact of Event Scale.
abstract: BACKGROUND
  Burn as a traumatic life incident manifests severe pain and psychological problems. Specific instruments are needed to evaluate burn patients' psychological issues related to the injury. The aim of this study was to translate and evaluate the reliability and validity of the Persian versions of Impact of Burn Specific Pain Anxiety scale (BSPAS) and Impact of Event Scale (IES).
  
  
  METHODS
  In this cross-sectional study, convenience sampling method was utilized to select 55 Iranian hospitalized burn patients. Combined translation was utilized for translating scales. Alpha cronbach, item-total correlation, convergent and discriminative validity were evaluated.
  
  
  RESULTS
  The Cronbach's α for both BSPAS- and IES-Persian version was 0.96. Item-total correlation coefficients ranged from 0.70 to 0.90. Convergent construct validity was confirmed by indicating high correlation between the scales designed to measure the same concepts. The mean score of BSPAS- and IES-Persian version was lower for individuals with a lower TBSA burn percentage which assessed discriminative construct validity of scales.
  
  
  CONCLUSIONS
  BSPAS- and IES-Persian version showed high internal consistency and good validity for the assessment of burn psychological outcome in hospitalized burn patients. Future studies are needed to determine repeatability, factor structure, sensitivity and specificity of the scales.
