title: Persian language version of the "Tinnitus Handicap Inventory": translation, standardization, validity and reliability.
abstract: Tinnitus is a debilitating condition that is widespread yet difficult to successfully diagnose and treat. This symptom can seriously affect the individual's life quality.
  
  
  OBJECTIVE
  The aim of current study was to compose and validate a Persian version of the Tinnitus Handicap Inventory (THI-P).
  
  
  METHODS
  The linguistic validation of the original version of THI into Persian version (THI-P) included translation, back translation and data gathering. The THI-P was administered to 112 tinnitus subjects. Age, gender, medical history and tinnitus characteristics were recorded as baseline information. All participants complained of chronic unilateral or bilateral subjective idiopathic tinnitus lasting for at least 6 months before consulting about their tinnitus.
  
  
  RESULTS
  There was no significant difference between gender, age, hearing impairment and total score and subscales of THI-P. Pearson product-moment correlations revealed adequate test-retest reliability for the THI-P (r = 0.96). Cronbach's-alpha coefficient indicated adequate internal stability of the THI-P (r= 0.943), with a total item correction varying between r=0.939 and r=0.944, indicating its reproducibility.
  
  
  CONCLUSIONS
  The present study proved the internal consistency/ coherency of the Persian version of THI (THI-P). This provides satisfactory application in clinical/research environments.
