title: Development and psychometric adequacy of the screening version of the tinnitus handicap inventory.
abstract: OBJECTIVE
  To develop a screening version of the Tinnitus Handicap Inventory (THI-S) and establish its psychometric characteristics.
  
  
  METHODS
  : Prospective clinical study to analyze 1) the level of predictability between THI and THI-S; 2) test-retest reliability of the THI-S; 3) 95% confidence intervals (critical difference scores) for the THI-S; and 4) a THI-S cutoff score used for referral purposes.
  
  
  METHODS
  Head and Neck Institute at the Cleveland Clinic, a tertiary care medical center.
  
  
  METHODS
  : Thirty-three patients reporting tinnitus as their primary complaint.
  
  
  METHODS
  There was, on average, a 16-day interval between test-retest administrations of the THI-S.
  
  
  METHODS
  Comparability of scores between the THI and the THI-S and test-retest reliability of the THI-S was assessed using Pearson product-moment correlations. The level of agreement between the 2 administrations of the THI-S was evaluated using Bland-Altman repeatability plots.
  
  
  RESULTS
  Comparability between the THI and THI-S was high (r = 0.90). Test-retest reliability of the THI-S was adequate (r = 0.81), as well as the level of agreement between administrations as demonstrated by the Bland-Altman plot. Based on 95% confidence intervals, pretreatment and posttreatment scores would have to differ by more than 10 points for intervention efforts to be considered significant. A 6-point cutoff score was analyzed as an appropriate fence for referral.
  
  
  CONCLUSIONS
  The THI-S is a psychometrically robust screening measure of activity limitation and participation restriction.
