      paralysis.

AB  - OBJECTIVES/HYPOTHESIS: The Voice Handicap Index-10 (VHI-10) is commonly used to
      measure patients' perception of vocal handicap. Clinical consensus has previously
      defined clinically meaningful improvement as a decrease >/=5. This study
      determines the minimal clinically important difference (MCID) for VHI-10 in
      patients with unilateral vocal fold paralysis (UVFP) using anchor-based
      methodology. STUDY DESIGN: Prospective cohort questionnaire analysis. METHODS:
      Two hundred eighty-one UVFP patients completed the VHI-10 on two consecutive
      visits (within 3 months). At the follow-up visit, patients answered an 11-point
      Global Rating of Change Questionnaire (GRCQ) scored from -5 to +5. Relationship
      between the GRCQ and change in VHI-10 was quantified using analysis of variance, 
      and MCID for the VHI-10 was determined using receiver operating characteristic
      (ROC) curve analysis. RESULTS: Overall mean VHI-10 change was -3.71 (standard
      deviation [SD] = 8.89) and mean GRCQ was 1.37 (SD = 2.51). Average interval
      between measurements was 1.73 months (SD = 0.83). Mean changes in VHI-10 scores
      were -7.45, -0.53, and +4.40 for patients whose GRCQ scores indicated
      improvement, no change, and worsening, respectively. Differences between mean
      scores were statistically significant (P < .001). Area under the ROC curve was
      0.80, demonstrating the classification accuracy of VHI-10 change scores. A VHI-10
      change of -4 was determined to be the optimal threshold that discriminated
      between improvement and no improvement (sensitivity and specificity 0.62 and
      0.88, respectively). CONCLUSIONS: The MCID for improvement in VHI-10 in UVFP
      patients is a decrease of 4. This information improves understanding of patients'
      response to treatment and allows comparison between different treatments. Future 
      research should determine MCID for VHI-10 across all voice disorders. LEVEL OF
